Product Description

The valve is composed of a valve head and a stem. The temperature of the valve head is very high (intake valve is 570~670K, exhaust valve is 1050~1200K), and it also bears the pressure of gas, the force of valve spring and the inertia force of transmission components. Its lubrication and cooling conditions are poor, and the valve must be required It has certain strength, rigidity, heat resistance and wear resistance. The function of the valve is specifically responsible for inputting air into the engine and exhausting the exhaust gas after combustion. From the engine structure, it is divided into intake valve and exhaust valve. The function of the intake valve is to suck air into the engine and mix and burn with fuel; the function of the exhaust valve is to discharge the burned exhaust gas and dissipate heat. In order to improve the efficiency of intake and exhaust, multi-valve technology is now used. It is common that each cylinder is arranged with 4 valves (there are also single-cylinder designs with 3 or 5 valves, the principle is the same). 4 cylinders have 16 valves in total. The "16V" often seen in automobile materials means that the engine has a total of 16 valves. This kind of multi-valve structure is easy to form a compact combustion chamber. The injector is arranged in the center, which can make the oil and gas mixture burn more quickly and evenly. The weight and opening of each valve are appropriately reduced, so that the valve can be opened or closed faster.
