Why should we increase the throttle when refitting a car? What are the advantages of modifying power? Will it increase fuel consumption?

Increasing the throttle is generally not a single modification. If you are a naturally aspirated car, you should have done cylinder liner operation on it.

For example, from 1.8 to 2.0, when your compression ratio changes, you need a bigger throttle to inhale more oxygen. If you just change the throttle.

There is no positive effect, just because the original compression ratio is suitable for the throttle intake of your original factory, so the number of times to clean the throttle is increased. How much air you blow in at this time, the value really used for compression combustion has not changed.

braking system

There are many ways to upgrade the brake system, such as replacing enlarged brake discs, multi-piston brake calipers and high-performance and high-temperature resistant brake pads with higher-grade brake oil or high-pressure brake oil pipes made of metal.

Another method is to replace the brake master cylinder with larger specifications and improve the auxiliary thrust of the brake pedal. As far as brake pads are concerned, they can be basically divided into two categories. One is ordinary driving, and the working temperature is between 50 and 450 degrees.

The other is for racing cars, and the working temperature ranges from 250 degrees to 850 degrees. High-temperature brake pads are not suitable for ordinary pavement, because the ideal braking effect can not be fully exerted before reaching the service temperature, which is easy to cause danger.

You can't have your cake and eat it. Comfort and handling are a pair of enemies. An important factor related to the extreme stability of the vehicle is the suspension system of the vehicle.

Most automobile manufacturers in the market will use soft shock absorbers to get a more comfortable road feeling under general driving conditions.

This kind of suspension should be enough for general driving, but if it is used for violent driving, it will be a bit inadequate, so the modification of vehicle suspension system is also very important.

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 most influential and modified item is the shock absorber. The modification of the shock absorber is actually to change a shock absorber with hard damping, good quality and full cooperation with the spring.

It is very important to choose a suitable shock absorber, and it is especially difficult to compromise between comfort and handling. But in pure competitive racing, everything is centered on manipulation, so a set of hard shock absorbers is undoubtedly more practical for modified cars.

The modification of the family car should proceed from the actual needs and be improved as needed after the use is clear, not just a single imitation. Whether it is to meet luxury or comfort, or to improve vehicle performance and make up for the lack of functions.

Always pay attention to ensuring the safety, passability and environmental protection of vehicles. Blind modification is not only not fun, but also dangerous.

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 there are many ways to improve the power output of an engine, such as changing the air-fuel ratio, expanding the forged piston, strengthening the connecting rod, changing the crankshaft, changing the high-performance spark plug and so on.

But 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. In the eyes of riders, the air filter installed on the original car seems to have insufficient air intake.

Therefore, car players have the practice of modifying the air intake system. This improved product is made of special chemical fiber. Its biggest advantage is that it can filter air, and at the same time, it can increase the flow and speed of air entering the combustion chamber, thus making the fuel burn more fully and the unit efficiency higher.

The performance of the engine is naturally different. The air filter used in the original car is a disposable product, while the modified high-flow air filter or mushroom head is made of higher material and can be cleaned and reused, which is more environmentally friendly.

exhaust system

The engine will exhaust exhaust gas after doing work, and the exhaust efficiency is directly related to the engine efficiency. The design of the original car tends to make the engine sound smaller, which affects the exhaust speed and reduces the engine efficiency.

With the increase of air intake and good combustion condition, the exhaust efficiency needs to be strengthened. Now it is mostly changed to direct exhaust, that is, the middle and front sections of the exhaust system are changed, and the muffler and other purification devices are removed, so that the whole exhaust process is shortened, and the exhaust gas is discharged after simple treatment, and the improved vehicle will accelerate faster.

The modified in-line bucket will release deafening sound when accelerating, but the vibration should not be too big, otherwise driving the vehicle for a long time will aggravate the driver's fatigue and irritability.
