The modification of the fuel supply system

The optimum air-fuel ratio of the engine is 14.7:1, but if the high-speed, high-load if you want to require higher engine output, usually want air-fuel ratio to 12:1-13:1. The modification of the fuel supply system is to "at the appropriate time to an amount of increase the amount of oil, so that the air-fuel ratio moderately larger. Modification of the jet fuel supply system can be divided into two categories of the changed hardware and change software, change hardware mesh to increase the amount of oil per unit of time. Change the software change its oil supply program. A regulatorThe pressure regulator in the system of multi-point injection passage of the nozzle, which is responsible for providing a fixed pressure, the greater the pressure, the amount of gasoline discharged by the same injection time more. Installation of a pressure regulator can be said that the modification of the fuel supply system, the most costly as the cheapest, and its installation is quite easy. Second, the injector
Third, oil supply computer chips usually professional tuner will supply special models modified with a computer chip. So the resulting oil program is still fixed, just amend the original car program, which is very important is no longer off the oil compensation off the oil injection program to control the time can be delayed or even canceled. The modification must be selected and your car modified condition similar chip.The variable program oil computer which is the most expensive in the fuel supply system modification is also the most effective one, is HALTEC computer. Via the computer owners in accordance with the degree of modification of the car engine with the air-fuel ratio meter measurements set out the best oil program, that is, before the text of the basic jet program as well as various compensation injection program can take advantage of an external laptop arbitrary changes. Its biggest advantage is the future engine and then the changed and modified, if the original oil program substandard condition can be corrected through the program immediately resolved.PlayHow happy how to playHigh-speed cornering Raiders bendIn high-speed corners is the larger arc bends (bend angle greater than 90 degrees) and can be used more than three-wave-band high speed through.Shui in high-speed corners often "outside the Chinese and foreign law mainly However, the greater the curvature of the bend, the turning point began difficult to hold up, imagine when the five waves bend close to a straight line passing through a turning point was to find out how difficult. So, when radians large high-speed corners to an extent, unless they are driving on the track, the corners are already know in advance, or should try to make their own growth in the inside lane of the time, so that it has been easy to drive.
SkillfulTips to solve a big problemCar clever refrigerationThe height of summer, the car in the sun for a while, the temperature inside the car could be as high as sixty to seventy degrees Celsius, then I wanted to drive this car is simply too painful. To come up with sprinted into the car starts, turn on the air conditioning to the wind speed maximum gear, then exit the vehicle waiting for a few minutes after the temperature inside the vehicle down into the car again. Actually, this is not only effective cooling methods have varying degrees of damage on the engine and catalytic converters, and to do so will cause the heat load of the air conditioning system, there are a lot of fuel consumed in vain. Here to introduce you to a few small ways.

Teach you Volvo Dice Vida clutch driving skills

Played a clutch as the important component of the car on the past and the important role so that the car smooth start, interruption to the power transmission system, with the shift, overload preventing drivetrain. Clutch nip, it ensures smooth transport of the power of the engine to the gearbox input shaft, in conjunction with the gearbox so as to achieve the purpose of the output power. There is also an important role in separation so that the gearbox input shaft and output shaft rotational speed synchronization to facilitate the shift.
The foregoing analysis clutch laminated to guarantee power output. Above said synchronization can smoothly shift to the clutch by the separation of the gearbox input shaft and output shaft rotational speed synchronization, in order to facilitate the shift, the key is the gearbox input shaft and the output shaft speed. Satisfied this premise does not depress the clutch so separated smooth shift. Specifically, by adjusting the speed of the engine when the clutch is not depressed in the nip state, that is, the engine speed is the rotational speed of the gearbox input shaft, as long as the shift operation can be performed in synchronization with the rotation speed of the output shaft. Eliminating the need to depress the clutch trouble. The clutch is wearing parts life, less natural to extend the service life.
However, this operation requires a certain amount of experience and skills, not blindly description section, or the transmission gears will be damaged, not worth the effort. The first description section clutch free operation Abstract file moving when you release the throttle the moment lever gently to the force pick a file, it will immediately slide into the neutral. 

Driving have this experience, is in the shift when the clutch is just step did not fully depressed, the clutch is not completely isolated, hand, feet, put a file, this is because the gearbox input shaft coincided with the results of the rotational speed of the output shaft, I said the clutch the operating shift the timing. Remember that speed and the speed will be able to repeat that shift.

Land Rover Defender interior conversion - luxurious aesthetic

Land Rover Defender for jungle and military students. Its life does not belong to the comfort of the city, just like the name "Guardian", its existence is to conquer. Service models in as many countries, military bases, fully embodies the Guardian of performance at the same time, this glory is irreplaceable.
 
Interior conversion, today the 60th anniversary edition Land Rover Defender from Cool Cars the town 5i5Car the in Beijing hand. When I saw the low-key that parking guards countless took a deep breath. From all appearances, it is difficult to be combined with the comfort, tall nose, earthy headlights, square shape, even you doubt pay big bucks to buy so neither comfortable nor beautiful the significance of the square box. Yes, the Land Rover Defender is not ready for fashion people, if you drove her shuttling between urban tarmac, then transfer it quickly!
 
The tall, narrow body leisurely in the harsh environment, to easily get rid of many difficulties. 16-inch wheels with General produced 235 off-road tires, minimum ground clearance 229mm, before and after the approach and departure angles of 51 ° and 53 °, respectively, this series of data to show its absolute is a cross-country players. I believe that here many interested in cross-country, men have been salivating longing for passion, do not hurry more temptation lie ahead. We mentioned earlier that the guards interior has been fully converted. Secretly revealing leather gloss dark brown with shades, subtle rough mad guards bring a little bit of luxury. Mclntosh audio from the United States in the trunk so that your body even if there are some fun in the tropical rain forest or muddy swamp. 

 The most interesting is the seat been replaced by the the German Recaro barrel chair drivers racing like wrapped.
Here I remind modification enthusiasts: the interior refit increasingly popular, it is also to make your car glow second spring magic weapon. But we must pay attention to the selection of interior materials, away from the toxic and hazardous or odor and shoddy products, these are the major factors affecting human health.

Method to increase vehicle lamp brightness

First, the lamp itself a problem. Have such as lampshades internal over-dirty; use shoddy lampshade, external sanding fade, will affect the luminescence. Lampshade can be removed to do the cleaning, or simply replaced;

Second, the lamp transformation of small power and lighting circuits design problem is relatively complex. A lot of car headlights are still using incandescent power 45/55W power is relatively small; headlights of some cars is directly on the separation of gross vehicle circuit harness the power transmission, the headlights get voltage than the total circuit The lower voltage to 1-2 volts. Ordinary incandescent lamp metal tungsten light in a vacuum environment to obtain the brightness, but the metal tungsten is energized under the vacuum environment, generating light while also generating the tungsten vapor, resulting in the gradual decline in brightness, lighting more darker.

If you want to improve the brightness of the headlights, do not directly replace the high-power light bulbs, as is likely to cause the circuit to overheat and even burn. But should be in the replacement of high power lamp at the same time, to change the circuit. Now the popular modified on the market in a better operability: the original car headlights interface of two is to plug an exterior circuit, through the vehicle's battery power transmission directly to the headlights, can guarantee a sufficient voltage; after the change of the original car headlight circuit used as a switching circuit, and in this way can the vehicle's headlights replaced 90/100W halogen lamp, brightness greatly improve the safety of driving at night is also greatly improved.

Often at dusk and dawn driving of the driver of the vehicle can be considered two small bright lights installed in the front of the vehicle, but also nice and safe.

Modified method on the headlights of the vehicle there is a better, but the price is expensive. That is, xenon headlights. The brightness of the lamp can be achieved the effect of sunlight. The use of such lamps, the visual fatigue of the driver driving the vehicle in the night greatly reduced, the security is also improved.

Snow day drive carefully to ensure safe arrival

Driving: snow driving attention to safety

    Braking distance increased speed increase, control speed and larger safe distance from the car in front is the key to driving of ice and snow. The same time, the snow driving, either to themselves or to others, to leave more distance:

    Slow traffic. Snow and ice road adhesion coefficient is very low, the wheel slippery, the greater the risk of driving, the driving speed is lower, in order to ensure safety. Moving speed to be smooth to prevent excessive speed, avoiding fierce acceleration. Need when accelerating or decelerating, the accelerator should be slowly depresses or loosen, to prevent drive wheel slippage due to sudden acceleration or deceleration.

    Snow slower traffic speed and distance between vehicles

    Maintain the distance between vehicles. Driving in the snow and ice on the road, rear-end accident prone, so to increase the driving distance to keep an appropriate distance from the vehicle, with the vehicle in front. The snowy ground resistance is small, only a dry asphalt road surface of 1/4, the brake non-secure area is greatly increased, too close with the car, it is difficult to within a short distance the brakes, once the situation is very likely to cause the rear-end. Distance from the vehicle in front, generally should be opened for more than 2 times the normal traveling distance.

 Encountered slow down in advance of the situation, and found that the front brake himself should immediately close oil and foot equipment ready on the brake pedal. If the vehicle is traveling too fast, safe distance of two workshops, in the event of an emergency situation, the consequences could be disastrous.

How to detect and maintenance handbrake

Foot brake pedal, handbrake handle a driving trip. Are usually required when pulling the handle to 70% of the entire trip, the handbrake system should be in the normal position of the brake, so check the handbrake before the braking force, you should first find out that 70% of the operating point of this work points can be the number the ratchet issued the "click" sound, until the handle is pulled to the end so far. Then calculate the sound of 70% of the total number of position, this position is the effective operating point of the handbrake handle. 
Car to the steep slopes of the pavement in good condition, slam the brakes hanging neutral (automatic hanging file in N), the handbrake handle is pulled to determine the operating point position. Then slowly release the brake pedal, if the car does not slip on the performance of the handbrake. Brake memory in the gap, sometimes after the pedal is released, the car will be a slight slide, and then come to a stop, as long as the sliding distance is small, the performance of the handbrake is normal. Uphill and downhill should each do. 
Addition to braking performance should also check the sensitivity of the handbrake, this is particularly important slope start. Slow driving on the road without the slope, slowly pulling the handbrake handle, feel the handle of the sensitivity and the junction. This the check method makes handbrake institutions wear should not be too much, so the number of inspections.In the above checks, if found unsatisfactory handbrake brake performance or sensitivity can usually adjust handbrake handling wire rope to solve. Connection at the bottom of the handbrake handle rope has an adjustable compensation mechanism, loosen the lock nut with a wrench, you can stretch the length of the brake cable. However, some cars adjusting mechanism is located at the bottom of the vehicle, if the inconvenience adjustment, should be left to professional maintenance staff to deal with.

In addition, some power larger cars, even in the case of the handbrake work started accidentally dragged handbrake driving will cause the hand brake and brake wear, handbrake and foot brake should be checked immediately after discovery performance.

The car modification Dictionary: short spring sports

Name suggests is relatively short spring sports short spring, its unstressed state the length and the length of the initial installation compared with the original car spring to short on a couple of centimeters. As we all know, the basic shock absorber shock absorber and spring combination, the components of these two parts can be separated replace them. Currently the most cost-effective method modified suspension system is the original car the original spring suspension system, the replacement of "short spring" modified car modification produced this short spring elastic resistance, short length, generally able to meet some appearance modifications, simply in order to reduce the vehicle chassis height modified vehicle owners.

    It needs to be noted that, due to the short spring and original spring there are differences in stroke and hardness, with a short spring and the original shock machine to use, whether it will cause the the original shock machine's overworked, shorten the shock machine use life, is still inconclusive. Short spring of the common market and other pitch springs and unequal pitch spring, they are the same hardness and stroke there is a difference, is not the same ride feel. Affect the spring-mass main processing materials, manufacturing processes and the diameter of the spring wire, the spring convoluted ratio (the ratio of the average diameter and the diameter of the spring wire of the spring), and so on.

Teach you to improve car performance modification

"Modified" - most people will think of the ride in the arena of imposing octahedral vehicle, those dizzying modified parts even more than the price of the vehicle, for most consumers is not practical 's. So let me introduce the for ordinary consumers modification programs.
 We must first distinguish change the purpose of the car, some people just want to change the car visually, such as modified surrounded by large, installed some lanterns, chassis lights, changed the interior of what such a modification of the car's performance in terms of no improvement . Another part of the pure and modified in order to improve driving pleasure.
Here I introduce to improve vehicle performance modification program:
1, balance rod.
Functions: to enhance body stiffness, inhibition of cornering roll, driving more smoothly.
2, enhanced ground.
Function: to reduce current consumption, eliminate clutter.
3, platinum or iridium spark plugs.
: Enhanced ignition performance, increase power, longer life.
4, high-performance ignition.
: Enhanced ignition strength, more complete combustion, fuel-efficient environmental efficacy, with platinum or iridium fire mouth better.
5, Headlight Brighter.
: Enhanced headlight brightness driving safer.

Car modification and exterior trim introduction

1, surrounded by largeThe scientific name is surrounded by a large body air spoiler assembly ", the material is carbon fiber. Surrounded by large car fitted to make the body longer, lower the car's center of gravity, the movement of air around the body to improve the characteristics to improve the car's high speed stability. However, surrounded by large domestic market mostly not after strict verification aerodynamics, may not significantly improve the aerodynamic characteristics of the body around this function is designed for the body beautiful.
2, body stickersBody sticker derived from motorsport, because all teams need more than the support of sponsors, so colorful sponsorship trademark of the body of the vehicle to become a Speed ​​advertising. Arena, the fans will like it, so the private car driving in urban and rural roads soon will put up a lot of stickers, its content is nothing more than a modified label, accessories trademark, lubricants ads.
3, tailThe car also with a certain amount of "Nouveau" If you like sports, certainly, and then the car fitted with 'a tail is a good choice. Car tail design principles with reference to the aircraft tail and do in the past for a long period of time, has been widely used in the car, after which they were transplanted into ordinary cars.Most automobile tail are made of glass fiber or carbon fiber, lightweight and tough, and put on a pretty tail, your car will be more angry.
4, automotive rust (engine guard plate, etc.)Car anti-rust mainly of two parts: chassis rust (chassis, chassis frame) with the car this rust (including skirts, fenders, door cavity, trunk, engine cover). Antirust processing method in composite metal surface spray varnish (ie sealed plastic), chassis rust is the key, so the owners have put the car rust treatment called sealed plastic chassis.
5, roof rackRoof rack can not only make your car the styling more "cool", but also can be useful when you travel. In general, station wagon and sport utility vehicle is more suitable for the installation of roof rack.

The speaker failure check

The car horn is not a frequently used device is sometimes necessary, but not wishful ringing or makes strange sound, very big sense of confusion.
The horn chirp big reasons for the poor are poor contact. Wherein, in particular the steering wheel around each contact, due to prolonged use, so that contact poor contact. Check the fault of the speaker, left and right to turn the steering wheel, if this case a larger the hissing friction sound, mostly contact surface is not smooth. To solve this problem, it can be removed to the upper cover of the steering column, injection grease to the contact portion. So most of them can reduce the hissing sound of friction, can also improve the response of the speaker.
For thorough maintenance of the speakers push switch contacts, it is necessary to remove the steering wheel itself to clear the dirt on the contacts, re-coated with a layer of grease, so that we can significantly improve the conductive contacts, which can be assured by move the car horn.
Check the speaker of the song, if you feel song not ringing, low and weak, are contacts of a bad contact.
Repeatedly pressing the switch, pressing the speaker if the speaker sometimes ringing, sometimes not ringing, mostly pressing the switch contacts within the contact is not good.
Left and right to turn the steering wheel, larger the hissing friction sound, injected some grease to the contact site.
If the speaker is completely sound, is likely to be a fuse is blown, check the fuse. Speaker power cord, to find the speaker's power cord, the wiring of the power cord plug disassembly, check whether there is poor contact.
If the horn chirp dull, very horn itself is faulty, then as long as the horns knocked most of them can be improved.

Highway lane driving -5 rules

The freeway run up happy chic, even the usually drive carefully ladies and the age of the vehicle is not too long "childish" drivers who have tasted recruit speed on the highway, "You" to 100 km / h or more. However, some every robbery by grinding, "many vicissitudes" old man "motorists they often taste have another choice: Ning to wear vegetable market, not take the" slaughterhouse "(highway). Up fine but wondering, there is some truth in this argument.In fact, "Zhiyizhibi, know yourself" discipline-honored, as long as a good understanding of the characteristics of highway driving, and then according to their actual ability to lane can be safely and quickly through the highway destination. 

1, the highway is generally much smaller than the city's downtown area density of vehicles, while the intersection, bend majority moderate, so the speed limit is higher. Many motorists in the high-speed set foot naturally and unconsciously speed mentioned that the upper limit of their ability to control the car, at which point any unforeseen circumstances will result in a dangerous situation or accident. So the most important thing is for highway traffic to control their emotions, maintain a safe speed, never exceeding the speed limit by speed limit signs. Of course, can not exceed their own ability to control the car to the pursuit of speed limits on the speed limit.  

Best to let the speed to 8O% lower than the capacity of their own control car.Highway speed, it seems everybody seems rapid staunch, but be sure to keep in mind the principle of the high-speed lane on the road should be: gentle, tender, and then gentle. High-speed traffic is the most taboo action blunt, hit the steering wheel when the steering to excessive over most of the rear wheels lose grip and cause loss of control of the vehicle. 

 Especially the current square unexpected, but can not scramble to play the direction should decelerate while as comfortable as possible to the direction of rotation, allowing the car to escape the danger smooth.3, 'early' referrals' late 'reporting' is also a highway driving one of the safety rules. Whether to overtake or to slow down, want to change the channel and line, or to exit the main road, each intent should be early signals of vehicles around the action has to later. Signals consequences of immediate action is often not the cause of the accident is to interfere with the normal running of other vehicles.

5 ways to solve the bad engine system cooling

Engine and air conditioning system cooling efficiency, causing the water temperature is too high following failure phenomenon:
    In bad traffic - traffic jams or long idling, engine water temperature gauge shows excessive, long working hours electronic fan high gear, the engine noise increases, the failure is most obvious when the temperature is too high off the air conditioning.
    Reminder: air conditioning refrigerant filling too little or too much will reduce the cooling effect.
    The car doctor Quotations: 5 warning signal to determine a patient
    When you take the car to the repair shop, should pay attention to the noise and symptoms related to the maintenance man described the the automotive performance degradation or problems. It can be said, the more you understand the car, the better you can describe the car failed to help the maintenance man to make a correct diagnosis, which prescribe the right medicine.
    1 new or unusual noise is usually the the car fault indication signal. For example, the low hum of voices could be bearing failure, may also just be a tire problem; screaming sound may indicate the need to replace the brake pads, or loose belt. In the description of the failure, it is best to explain clearly the reason or action causing the noise.
    Addition to performance loss or noise indication signal on the instrument panel is another place can not be ignored. Carefully read the user manual of the car, to understand the meaning of various signals that can help you to discover a new failure.
    If you feel the steering wheel while driving tight car to one side, or abnormal vibration in a certain speed range, you need to check the tire or wheel balance and positioning. Just found these problems in a timely manner for maintenance can prevent the failure to continue to expand, but also to avoid a greater loss.
    4. Require special attention with the braking system, braking system have a very close relationship with traffic safety, to ignore such failure is tantamount to take personal and other people's lives do adventure.
    Note the car start smoothly. If the car begins to become difficult to start, the best time to open to the repair station overhaul.

car modification knowledge in multi valve engine technology

 The multi-valve technology by improving the intake air, increasing the output power of the engine. 2-valve engine intake limited cross-sectional area at high speed is likely to cause its intake is not smooth, multi-valve technology will be able to change this situation effectively.


 4 valve engine

    Traditional 2-valve engine can only occupy 1/3 of the area of ​​the top of the combustion chamber as the area of ​​the intake port, the intake efficiency is limited. When the 4-valve engine plot with respect to the 2-valve engine, the cross section of the intake air can be increased more than 50%, and more suitable for high speed running smoothly. Meanwhile, since the 4-valve design may be a spark plug can be disposed at the center of the combustion chamber, the flame of the spark plug can be more evenly distributed to the respective corners of the combustion chamber, the combustion of the mixture can burn more fully, the heat loss is small, so the 4 valve engine is also more conducive to improve combustion efficiency and reduce emissions.

    The 4-valve engine can be designed two camshafts to drive the valve, a driven intake valve, a drive exhaust valve, can be more accurately controlled, and may adopt more new technology. Now, most mainstream 4-valve engine with a double overhead camshaft design. Honda and Mitsubishi in its ordinary civilian car still prefer to use a single overhead camshaft for cost considerations. It needs to be arranged on the camshaft rocker, ultimately driven by rocker valve. This design can reduce costs, but increase the frictional resistance and movement inertia affect the power output when the high engine speed. Honda and Mitsubishi sports car for performance improvement considerations are equipped with a dual overhead camshaft design engine.
3 valve engine

    Early multi-valve engine in general using three valves, this is due to the technical structure of valve 3 is simple - the three valves may be arranged in a straight line, so only need a camshaft of a cylinder can be simultaneously driven into the and exhaust valves. Until now, still a small number of multi-valve engine with this low-cost design, for example, the old Mercedes-Benz V6 and V8 engines, KIA Maxima 1.3 liter engine. Of course, this low-cost design for improving the work efficiency of the engine is very limited.

    4 valve engine

    Traditional 2-valve engine can only occupy 1/3 of the area of ​​the top of the combustion chamber as the area of ​​the intake port, the intake efficiency is limited. When the 4-valve engine plot with respect to the 2-valve engine, the cross section of the intake air can be increased more than 50%, and more suitable for high speed running smoothly. Meanwhile, since the 4-valve design may be a spark plug can be disposed at the center of the combustion chamber, the flame of the spark plug can be more evenly distributed to the respective corners of the combustion chamber, the combustion of the mixture can burn more fully, the heat loss is small, so the 4 valve engine is also more conducive to improve combustion efficiency and reduce emissions

Car Audio routine maintenance tips and four Troubleshooting

The car audio considered important parts in the automotive equipment, good sound allows you to enjoy the journey in the wonderful music, to reduce driving Lawton sense. Especially when you Lu-yu traffic jam, surround sound, high-quality CD series of notes out of rhythm, irritable mood soon evaporated. However, the city's dirty and dust is the biggest enemy of your car stereo, so be sure to pay attention to regular cleaning and maintenance of car audio.

    1 often wipe with a wet cotton swab

    Audio cassette machine platen and the head of the CD player are easy to dust accumulation. The most important parts of the CD player laser head laser head wearing parts and more expensive, should focus on conservation. Although now part of the car stereo in the design process to consider the problem of dust, but the protective measures is necessary, you can often use a wet swab to wipe the cassette tape cartridge, and the disc slot CD player as well as a panel of the sound system.

    2 cleanup tool cleaning tape and CD-ROM

    In addition to audio host kept clean, tape and CD-ROM should guarantee clean. The dirt will not only affect the sound quality of the playback tape and disc damage even be sound. CD player laser head at high speeds, dust, make the laser head deviate from the track of the original laser, resulting in distortion of the sound, and the laser head damage. It is understood, tape and disc cleanup tool can buy in most audio and video store.

    3, slow disk less disc change

    Spring is the high incidence of damage to the car audio laser head, because of the dry climate, prone to static electricity. Put the disk when it is best not to directly touch by hand, do not take the middle, slowly into them, try not to frequent CD changer plug plate to make lighter.

    4 Do not suddenly maximize volume

    Audio use them to avoid a sudden maximize volume, so that the speaker coil will burn, the amplifier will affect the amplitude suddenly increase also burning power amplifier.

    Common Faults

    Car audio is generally difficult to achieve due to the environment of the effect of the same grade home audio, home audio than in the course of some failures easier, Here are some common car audio fault and fault exclusion method.

Positive and negative effects brought by BMW 5 long wheelbase

Wheelbase like discussion today we discussed the car, the house facing south or north just as common and important. Obviously, you can see the impact of increased wheelbase also obvious need long-term feelings only experience the difference.
Positive impact
A space increases. The increase of the wheelbase, often at the same time will increase the track (height is not necessarily). For example, the 2010 BMW wheelbase is 3028 Wheelbase 1558 and 1581, while the the 2011 BMW wheelbase is 3108, the front and rear tracks of 1600 and 1627, respectively. Therefore, the increase of the wheelbase is the means that the vehicle becomes longer fat. The direct benefits of variable length fat of course, is the increased space.
Second, increased comfort. Increased comfort is also well understood. Imagine you lying in a 2 m long bed, bed one was filed a meter high, the other head is still on the ground, it is estimated that you can not lay, but slide down. But if you lie is a 10-meter-long bed, a lift of 1 m, it is estimated that not sleeping, you wake. Although this is an exaggerated example, but the truth is, the longer the width of the car, in the face of the same bumps, the smaller the internal changes, so the more comfortable.
Negative impact
Three car look a bit difficult to avoid touching the rear wheel. The larger the car, see a bit more difficult, "turn to turn, but" I believe we can guess intuitively. But in the end Difficulties How things have changed? How to avoid I am afraid that is not easy to say clearly. To see bit difficult, let's do an experiment.
Attentive friend should ordinarily be able to find this problem: steering wheel, if the pool of water on the ground, there is left round India. Seal of the front and rear wheel does not coincide, sometimes deviate from the big points, sometimes deviate from a small point, steering wheel play more small turning radius, deviate from the big hand on small. If we look at the analysis, you will find: the rear wheel of the imprinted forever in the same side of the inner side of the front wheel.

How to care for BMW OPS DIS V57 tire frequent flat

Their car in heavy rain occurs, such as engine suddenly stalled, brake runaway, which is mostly a flat tire. The experts have warned that the rainy summer, the public car should drive carefully in the rain, after the rain, do not forget to doing the maintenance for the car.
"To the rainy season, more tires damaged leak, one morning today, there are several cars to fill tires." Second Ring Road of an auto repair shop owner Zhang Xiaodong, told reporters slippery due to rainy weather, combined with the road surface is not small puddle, the car quickly through, is likely to hurt the tires.
Remind car owners, rainy day traveling to be careful to avoid the foreign body, encounter puddles when the speed is not too fast. When feeling increasingly heavy or there is a body tilt steering wheel, it may be a flat tire, car owners should find the nearest repair shop processing. Zhang Xiaodong, also listed in the public a rainy car maintenance list.
1, should be promptly cleaned. Some owners believe that rainy day without car wash, In fact, encountered heavy rain, the car should be carried out promptly cleaned, otherwise the gap at the front and rear car tires easily accumulated sludge, moisture hiding them, the car body will rust. To prevent of acidic substances rainwater damage to the body, the most simple and effective way owners can prepare a dry cloth, the body to conduct a simple wipe Until the weather turned fine after the repair shop or 4S shop to the car to a full range of waxing and polishing once sealed glaze.
2, rainy day cover sewing more susceptible to injury. In addition, many owners habits put on a sewing machine to the vehicle, although you can prevent damage to the vehicle surface, but weather such as the case of wind and rain, sewing repeatedly whip paint, especially when sand blown into sewing, to draw countless Road tiny scratches in the body of the vehicle, and over time will cause the paint to darken.
3, the scratch should be repaired immediately. Car surface scratch place, paint protective layer peeling a case of damp weather, rust born. Therefore, the body of the vehicle spray paint peeling or deeper scratches should be repaired immediately, and regular inspection and cleaning drainage holes at the bottom of the door and the body.
4, the self-check whether the brake fluid damp. Produce a lot of water in the rainy season when the wet weather causes the brake fluid cup and into the brake fluid. If moisture into the brake fluid, the heat generated by the vehicle in the braking process transpiration a lot of water vapor, the compressibility of gas will cause Zhidongshiling or even failure.
The owners three cases confirmed brake system: brake very deep need to step on the brakes heard a noise, extended braking distances than ever before, to appear in one of three vehicles to go into the repair plant inspection.

5, headlights, fog into a hidden danger. Rainy day, the car's headlights easily water affected brightness change the direction of the light exposure, may also damage the headlight, a security risk. If mist in the headlights, you can open the headlights. Open 10 minutes after the lights mist began to disappear completely disappeared after one hour; if there is mist, it is necessary to professional service station for processing.

Digimaster III Original and naturally aspirated distinction

Turbocharged, supercharged and naturally aspirated distinction
  Often said that natural air intake car and turbo models the upgrade how different, in the end, what is the naturally aspirated models and turbine models it Xiaobian to share with you the next.
   The most common way to the suction by the piston in the suction process using natural pressure intake air, the air passes through the air cleaner, the throttle and fuel to form a mixed gas to enter the cylinder. In this way is called a naturally aspirated engine (NA). This car is also known as the naturally aspirated models.

    Of course, more large displacement engine, the cylinder volume is greater, once the intake air amount is the greater, the stronger the power of the engine, and the truth is not in doubt. During power conversion, it tends to expand cylinder volume or direct transplantation of a larger displacement engine. However, the engine displacement is restricted, that is to expand is impossible case taken to install additional booster, mandatory pushes air into the cylinder is also very common. This engine is a supercharged engine.

    According to the characteristics of the engine, two different supercharged, turbocharged engine (Turbo Charger) and a supercharged engine (Super Charger). Thus the car into mechanical the supercharger models and turbocharged models. They are being used in different types of engines, because of the working range of different. For the modification of the engine, the means of installation of the turbocharger in the naturally aspirated engine is very important.

    Visualize the turbocharger like is installed in the intake duct of the engine on the one facing the cylinder internal hard hair blower. The turbocharged engine fan is formed by the use of engine exhausts reflux rotation, so the formation of sufficient pressure to promote the turbine blades rotate, when the engine reaches a certain speed the job. Means that the turbine blades are not immediately blast, this does not form a pressurized period of time known as "turbo lag" (Turbo Lag), it occurs just on the engine speed rise after the sharp decline of the engine speed or early rapid acceleration initial also that the engine speed is in the region between 1000 ~ 3000r/min.

    Another, the working principle of the supercharged engine, the turbocharger through the belt as connecting the cooling pump as directly connected to the engine crankshaft is rotated by the rotation of the crankshaft driven turbocharger blades, to provide a greater amount of air for the engine . This has the advantage that it is unlike the turbocharger, as there is a turbo-lag phenomena, because the rotation of the mechanical supercharger is synchronized and the crank. That is, once the engine speed increases, the turbocharger immediately.

Turbocharged, supercharged and naturally aspirated distinction

Turbocharged, supercharged and naturally aspirated distinction
  Often said that natural air intake car and turbo models the upgrade how different, in the end, what is the naturally aspirated models and turbine models it Xiaobian to share with you the next.
   The most common way to the suction by the piston in the suction process using natural pressure intake air, the air passes through the air cleaner, the throttle and fuel to form a mixed gas to enter the cylinder. In this way is called a naturally aspirated engine (NA). This car is also known as the naturally aspirated models.

    Of course, more large displacement engine, the cylinder volume is greater, once the intake air amount is the greater, the stronger the power of the engine, and the truth is not in doubt. During power conversion, it tends to expand cylinder volume or direct transplantation of a larger displacement engine. However, the engine displacement is restricted, that is to expand is impossible case taken to install additional booster, mandatory pushes air into the cylinder is also very common. This engine is a supercharged engine.

 According to the characteristics of the engine, two different supercharged, turbocharged engine (Turbo Charger) and a supercharged engine (Super Charger). Thus the car into mechanical the supercharger models and turbocharged models. They are being used in different types of engines, because of the working range of different. For the modification of the engine, the means of installation of the turbocharger in the naturally aspirated engine is very important.

Teach you how to quickly listen the converted audio quality

It is well known car audio component departments are usually composed of four parts by the host, speaker, amplifier and subwoofer, subwoofer allows the sound field to extend the music kind of gentle feeling. However, the installation of the car subwoofer gate technology live, if you choose properly, it will be counterproductive, music, sounds dim and cluttered.For many audiophiles, they only ears can hear a car audio with perfect sound quality, but for mostly primary modification of my friends, to identify a good sound quality, or difficult. Treble field is certainly to improve, but the subwoofer is also indispensable, because it will make enjoying the sound more charming funChoice of speaker audio positioning
First, from the human ear can hear the audio range, the range between the extremely high frequency of 20Hz ELF to 20000Hz, if the modified sound, audio tweeter range generally can be overridden to 20000Hz, but the bass speaker For as low as 20Hz is extremely difficult. On view common audio speakers, 5 inches, 6-inch woofer speaker because the speaker cone area as well as the operation of stroke limit, can play a 60Hz ELF has been quite good, if the layout of the sound field is not reasonable or poor installation conditions, even low frequency sound below 100Hz will be difficult, this speaker sounds bass dry Shen, dynamic, lost this flexibility, and the breadth of the entire sound field and the extension of sense will restricted music gives the feeling as buoyant in the air, top-heavy insecure. So, the sound quality of the subwoofer range limited you have to be less than 100Hz course, 60Hz better, 20Hz, almost.The horn good sound quality to be okay?
