Laotie, where is the most professional car speaker modification in Qingzhou?

Automobile refitting refers to the external modeling, internal modeling and machine design of the prototype car produced by automobile manufacturers according to the needs of the owners.

The change of mechanical properties mainly includes body modification and power modification.

Modified parts:

braking system

There are many ways to upgrade the braking system, such as replacing enlarged brake discs and multi-piston brake calipers and high-performance high-temperature resistant brake pads.

In addition, you can also change into a higher level of brake oil, or replace the high-pressure brake oil pipe made of metal. Another way is to change.

Install a larger brake master cylinder to increase the auxiliary thrust of the brake pedal. As far as brake pads are concerned, they can basically be divided into two categories, one is universal.

For driving, the working temperature is between 50 and 450 degrees; The other is special for racing cars, and the working temperature is between 250 and 850 degrees, which belongs to high temperature.

Brake pads are not suitable for ordinary roads, because they cannot achieve ideal braking effect before reaching the service temperature.

It is easy to cause danger.

Suspension system

The modification of suspension system can be roughly divided into replacing shock absorber, strengthening suspension structural rod and installing balance rod. Among them, the influence is the biggest and the most.

The multi-person modification project is the shock absorber. The modification of shock absorber is actually to replace it with harder damping, better quality and enough springs.

Matching shock absorber.

engine power

The engine is to the car what the heart is to people, which is the most important part of the whole car. Although the power output of the engine has many aspects.

The method can be upgraded, such as changing the air-fuel ratio, expanding the forging piston, strengthening the connecting rod, replacing the crankshaft and replacing the high-performance spark plug. But it

The process of modification is basically divided into improvement, exhaust and ignition system modification.

Gas treatment system

The air filter on the engine is used to filter the air needed for engine operation. This device is installed on a gasoline engine.

From the driver's point of view, the air filter installed in the original car seems to have insufficient air intake. Therefore, car players have the practice of modifying the air intake system.

The engine will exhaust exhaust gas after doing work, and the exhaust efficiency is directly related to the engine efficiency. The original car design is often smaller.

Motion sound affects exhaust speed and reduces engine efficiency. When the intake air volume increases and the combustion condition is good, the exhaust efficiency also

Need to be strengthened.

oil supply system

The optimum air-fuel ratio of the engine is 14.7: 1, but if you want to get higher engine output at high speed and high load, you usually have to leave it empty.

The fuel ratio is increased to12:1~13:1. The reform of the fuel supply system is to increase the fuel supply at an appropriate time to make the air-fuel ratio change moderately.

Large quantity, timely and appropriate amount are also the basis for judging the quality of oil supply system.
