The role of the valve is specifically responsible for the input of air into the engine and exhaust the exhaust gas after combustion. From the engine structure, it is divided into Intake Valve and Exhaust Valve.
The role of the intake valve is to draw air into the engine and mix it with the fuel to burn; The function of the exhaust valve is to discharge the exhaust gas after combustion and dissipate heat.
The valve is composed of a valve head and a rod. The valve head temperature is very high (intake valve 570~670K, exhaust valve 1050~1200K), but also withstand the pressure of the gas, the valve spring force and the transmission component inertia force, its lubrication, cooling conditions are poor, requiring the valve must have a certain strength, stiffness, heat and wear resistance.
The intake valve is generally made of alloy steel (chromium steel, nickel-chromium steel), and the exhaust valve is made of heat-resistant alloy (silicon chromium steel).
Sometimes in order to save heat resistant alloy, the exhaust valve head is made of heat resistant alloy, and the rod is made of chromium steel, and then the two are welded together.
