Ignition system
Ignition systemBySpark plugCombined with the ignition wire, the original car configuration is a single groupWire harness, The passability and throughput of voltage and current are not satisfactory. There are many types of spark plugs. The materials are nickel, platinum, and iridium alloys. There are single-head, double-head, and four-head differences in form, and there are differences in high temperature and low temperature in heat resistance. The selection of spark plug can be based on the compression ratio of the engine,SpeedAnd air-fuel ratio. Engines with high compression ratios need to use spark plugs with high temperature resistance; conversely, spark plugs with low compression ratios have a correspondingly lower temperature resistance. The temperature resistance of ordinary spark plugs is 6 to 7 degrees. Due to the increased power of the modified vehicle, the spark plug needs to be improved a little bit in temperature resistance.

The temperature resistance of ordinary spark plugs is 6 to 7 degrees. Due to the increased power of the modified vehicle, the spark plug needs to be improved a little bit in temperature resistance. Generally, the original factory uses a 7-degree spark plug, and after the modification, it should be increased once to use a 6-degree spark plug. If the spark wire and spark plug are replaced, the engine performance will be improved instantly, the throttle will harden, and the start will be rapid.
People who like to play cars generally hope that the speed of the car is strong enough and the braking distance is short enough. However, most of the original cars in this aspect are mostly moderate and can not meet the needs of car users. Then, after changing the power, you need to talk about changing the brakes. NS.
Braking System
There are several ways to upgrade the brake system. In addition to replacing high-performance discs, you can also use higher-grade brake fluid, or use metal high-pressure brake hoses. Another method is to replace brakes with larger specifications. Multiplier to increase the auxiliary thrust of the brake pedal.byBrake padsBasically, it can be divided into two categories, one is for ordinary driving, the operating temperature is between 50 degrees and 450 degrees; the other is for racing, the operating temperature is from 250 degrees to 850 degrees, high-temperature brake pads are not suitable for use in It is usually used on the road, because it can not exert the ideal braking effect before reaching the operating temperature, and it is easy to cause danger.
You can't have both fish and bear's paws. Comfort and handling are themselves a pair of rivals. The suspension system of the vehicle is an important factor related to the speed and stability of the vehicle. Most family car manufacturers on the market now use softer shock absorbers to get a more comfortable road feel under normal driving conditions. This kind of suspension should be sufficient to deal with general driving, but if it is used to deal with violent driving, it seems a little powerless, so the modification of the vehicle suspension system is also very important.
Shock absorber, suspension system
The modification of the suspension system can be roughly divided into replacing the shock absorber, strengthening the suspension structure rod, and addingBalance barWait. One of the most influential and most modified items is the shock absorber. The modification of the shock absorber is actually to replace it with a shock absorber with harder damping, better quality and capable of fully cooperating with the spring. It is very important to choose a suitable set of shock absorbers. It is especially difficult to achieve a compromise between comfort and handling. However, in a purely competitive racing car, everything is centered on control. At this time, a set of tough avoidance The shock is undoubtedly more practical for modified cars.
familyCar modificationWe should proceed from actual needs and make improvements as needed after the purpose is clarified, not just a single imitation. Whether it is to satisfy 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 the vehicle. Blind modification is not only not fun, but also dangerous.
Engine power
The engine is to the car as the heart is to the person, and the most important part of the car lies in this.Although the power output of an engine can be upgraded in many ways, such as changing the air-fuel ratio and expanding the forgingpiston, Strengthen the connecting rod, changeCrankshaft, Change the spark plug, etc. However, the modification process is basically divided into improvement, exhaust, and ignition system modification.
Intake system
The air filter on the engine is to filter the air needed for the engine to run. This device is available on gasoline engines. From the perspective of car players, the air filter installed in the original car seems to have insufficient intake air. Therefore, car players have the practice of modifying the air intake system (commonly known as Mushroom). The modified product is made of special chemical fiber. Its biggest advantage is that while filtering the air, it increases the air flow and velocity into the combustion chamber, so that fuel combustion is more complete, the unit efficiency is higher, and the engine performance Naturally different.
Exhaust system
Exhaust gas will be discharged after the engine has done work. The performance of the exhaust is directly related to the performance of the engine. While the intake is increasing and the combustion is intact, the exhaust efficiency also needs to be strengthened. Now it is mostly changed to direct exhaust, that is, changing the middle and front sections of the exhaust system, removing the muffler and other purification devices, shortening the entire exhaust process, and the exhaust gas is discharged after simple treatment. After the improvement, the car will accelerate more quickly. The modified inline barrel will release loud noises when accelerating, but the co-shock should not be too large, otherwise it will aggravate the driver’s fatigue and irritability when driving the vehicle for a long time.
