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.

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.

How modified xenon headlamps also has standard

Modified xenon lamp standard due to the different works, the xenon headlights basic assembly including: light bulbs, ballast, lens. Lamp naturally do not have to explain, is the main unit of luminous, color temperature and brightness depends on it. Ballast is provided for the driver of the bulb 23000V instantaneous high voltage equipment, along with overload protection circuit control drive current role. Lens is constrained to the light, the light is concentrated in one area, not everywhere radiance (Remember not to install the lens harm to others).

Bubble the color and brightness of the indicators:Color indicators (color temperature):The color temperature not represent the brightness on behalf of a light color, light intensity in lumens. So our choice of lighting can not color temperature as a reference, and gives the impression of more than 5500K color temperature of light is very dazzling!Color temperature to absolute temperature K, is heated to a standard black color when the temperature rises to a certain extent by the red, orange, yellow, green, blue, violet, purple and gradually change, the use of such a light color changes characteristics, is defined as the color temperature

Indicators brightness (lumens):Lumens luminous intensity referred to light strong international unit is the candela (cd) short cd. Lcd is the light source of the luminous flux emitted within a unit solid angle in a specified direction. Specific not Here, interested owners can understand, we only need to remember that the greater the lumens represent higher luminous intensity on the line.Some knowledge of the bulb:Halogen lamp label:In accordance with the progress of science and the development, most of the car accessories are standardized, the lights are no exception lights used standard H1, H3, H4, H7. And reference numeral T shows the diameter of the lights, for example, T5 bulb diameter of 5 mm, T10 is 10 millimeters.

Standard xenon lamp is not using the above code, but the use of the "D * X" code. For example: D1S, D2R. Where D represents xenon bulb, for digital code "1, 2, 3, 4", the singular with starter, double the number without starter. 1,2 mercury design, 3,4 for the mercury-free design. X is a letter: "S, R", S for the lens; R denotes a reflective bowl.

Car modification affect the used car price

Paint a matte, a change surrounded ...... the car to a greater pull the wind, but you thought, which may affect the value of its used car? Recently, a reporter investigating the used car market in Hangzhou, the conclusion is - car modification, which will definitely affect the used car price! However, the modification actually makes the car devaluation or appreciation will depend on what kind of car, how to change it. Some luxury cars would rise later to turn over
Modified later, the prices will really reduce it? Monday, second-hand car market in Hangzhou Motor City, the reporter consulted on this issue, a number of merchants. Get the answer is basically the same - will! "Most of the modifications indeed would lower the prices of second-hand car." Hangzhou easy first motor vehicle brokerage company Niliang Yong told reporters, in which the main reason there are two points: first, the modified car is a relatively small customer base. Change color, for example, will tend vehicles have changed maverick, but this is not acceptable to all. The customers N group equivalent difficult to dispose of a used car, naturally it will affect the price. Second, high maintenance difficulty. For example, change color, change the exhaust change surrounded the future in case the car is broken, or out of the accident, a lot of trouble to repair. Some of the car, where the change, have back where repair, which is equal to an increase of the cost of maintenance.
The reporter asked the market circle, found difficult to sell second-hand car modifications, examples abound - a matt yellow horse 6 months Shaorenwenjin second-hand merchants anxious; exhaust pipe of a Subaru Impreza, changed denied when transfer business completely yellow ... Used car dealers say, do used car funding pressure, usually in a car from acquisition to sell the resale cycle 3 to 7 days. Modified cars this cycle will be stretched at least doubled. Met modified car, they tend to drive down the purchase price - unless it is very cost-effective, otherwise, do not accept.
However, not all modifications to the second-hand car will decline in value. "We are here there is often a modified car easier to dispose of than ordinary used car." Hangzhou Shuguang used car company official said, "such as cars Maserati sports car. Before Sapphire owners later changed to a matte white look better and more personalized. changed color, at least be able to sell more than 1 million more recently, a Porsche 911, turn over the exhaust pipe, and selling more expensive than the normal 911.
