What is the function of the valve?

[AthenaRose]

The function of the valve is intake and exhaust. Here are the related introductions: 1. Structure: Engine valves are divided into intake valves and exhaust valves. When the intake valve opens, the air-fuel mixture enters the cylinder. After being compressed by the piston and ignited by the spark plug, it turns into exhaust gas and is expelled through the exhaust valve. 2. Function: The valve is specifically responsible for introducing air into the engine and expelling the exhaust gases after combustion. In terms of engine structure, there are intake valves and exhaust valves. The intake valve's role is to draw air into the engine to mix with fuel for combustion. The exhaust valve's role is to expel the burned exhaust gases and dissipate heat.
