Overview of engine intake and exhaust valves

Today, the editor brought friends knowledge about the intake valves of automotive engines. The function of the gate valve is to input gas into the engine and exhaust the exhaust gas after combustion. From the perspective of engine structure, it includes intake and exhaust valves. The function of the intake valve is to suck gas into the engine and mix it with fuel for combustion; The function of the exhaust valve is to discharge exhaust gas, which emits heat after combustion.

Engine intake valves: valve functions

The gate valve is specifically responsible for inputting gas into the engine and emitting exhaust gas after combustion. From the perspective of engine structure, it includes intake and exhaust valves. The function of the intake valve is to suck gas into the engine and mix it with fuel for combustion; The function of the exhaust valve is to discharge exhaust gas and heat after burning.

Engine intake valves: current situation

In order to ensure intake and exhaust efficiency, multi valve technology is currently commonly used. Each cylinder often has four valves (one cylinder also has three or five valves, with the same principle, such as the Audi A6 engine). The four cylinders have a total of 16 valves, and everyone has car data
