Four ways to improve the power part of automobile modification knowledge

1. If the car wants to improve the power, it can enterThe following modifications: modification of exhaust and engine intake: modification of the exhaust system to reduce the exhaust return pressure, reducing the return pressure is actually to make the alternation of suction and exhaust smoother, which is equivalent to prolonging the overlapping time of the valve.

2. Changing the cylinder gasket or transforming the cylinder The combustion efficiency of the engine affects the explosive power of the mixed gas. How to complete the combustion process of the engine in the shortest time and produce the maximum explosive force is closely related to improving the engine power.

3. Upgrade exhaust throat technology: Using a high-performance exhaust throat system can effectively improve the performance of engine operation and enhance the power of the car. Replace the fuel injector: Replacing an ordinary fuel injector with a high-performance fuel injector can improve the combustion efficiency of fuel, thus increasing the power of the engine.

How to modify a car

The easiest way to change the appearance of the car body is to install an aerodynamic kit. The so-called aerodynamic kit is commonly known as the big bag, which basically includes the air intake grille, side spoiler (side skirt), rear surround and rear spoiler flow (tail wing), etc.

For example, installing navigation, inControl large screen, reversing radar, driving recorder, audio system, etc., or replace the interior chair cover, add sports kits, etc. In a word, the scope of modification of the interior is very wide. Generally speaking, as long as it does not affect the safety structure of the vehicle itself, most of them are legal and do not need to be approved. Change the color.

First of all, for the appearance decoration, there is no problem with conventional paint decoration, but the spraying cannot imitate public vehicles such as police cars and fire trucks.

Car modification must-read basic knowledge: Car modification must-read basic knowledge Modification is not only an expression of personality, but also an attitude towards using a car. The modification effect of a car represents the taste of the owner and his views on driving.

The only way to increase the speed of the vehicle is to start with power. The most basic thing is to replace high-voltage wires, spark plugs and exhaust pipes.Then, Bian Xiao will tell you some tips for modifying cars. Replacing high-voltage silicon wires and spark plugs with strong discharge can indeed strengthen the ignition.

What are the projects of car modification?

The items of automobile modification include: engine modification; chassis modification; electrical equipment modification; body modification; in-car modification; safety device modification; entertainment and information system modification; off-road vehicle modification, etc.

Car modification includes engine modification, chassis modification, electrical equipment modification, body modification, car interior modification, safety device modification, entertainment and information system modification. The following is the extended information: engine modification: intake system, exhaust system, oil supply system, crankshaft connecting rod mechanism, gas distribution mechanism, compression ratio, supercharging system, etc.

etc. More modification items are as follows: security device modification: anti-theft device, reversing radar, safety warning system, etc. Entertainment and information system modification: audio, in-vehicle hands-free, walkie-talkie, in-vehicle GPS, car black box, etc. Off-road vehicle modification: protective rod, anti-roll frame, off-road vehicle tires, off-road vehicle lights, winches, etc.

Different types of modifications have different items: bumper modification After getting a new car, some car owners may pay more attention to the safety of the car and feel that the front and rear bumpers of the original car are not strong enough, so they do bumper modification. There is no problem with this, and the annual review can be passed.
