The function of the valve is specifically to introduce air into the engine and expel the exhaust gases after combustion. From the engine structure, it is divided into the intake valve and the exhaust valve. The intake valve's role is to draw air into the engine, where it mixes with fuel for combustion; the exhaust valve's function is to expel the combustion gases and dissipate heat.
