The respective functions of valve group parts

Automobile valve, also known as throttle, is responsible for inputting fuel to the engine and discharging exhaust gas.

In traditional engines, each cylinder has only one intake valve and one exhaust valve. Multi-valve technology is widely used now. Usually, each cylinder is equipped with four valves. This multi-valve structure is easy to form a compact combustion chamber, and the fuel injector is arranged in the center, which can make the fuel-air mixture burn faster and more evenly, and the weight and opening of each valve are reduced appropriately, so that the valves can be opened or closed faster.
