What is the role of motorcycle valves?

The motorcycle valve is a key component of the engine, primarily consisting of the intake valve and the exhaust valve. These valves are responsible for controlling the intake of the air-fuel mixture into the engine and the discharge of exhaust gases after combustion, respectively. Their central function is to ensure the precise operation of the engine's air intake and exhaust processes, directly affecting combustion efficiency and output power.

The specific role of valves

Intake port: It opens during the engine's intake stroke to mix the intake air cylinder with fuel, forming a flammable mixture. This process determines the amount of air entering the engine and directly affects the adequacy of combustion and the output power.

Exhaust port: It opens during the engine's exhaust stroke to expel the burned exhaust gases from the cylinder and, at the same time, remove some heat through the flow of exhaust gases, helping the engine dissipate heat. The efficiency of the exhaust directly affects the engine's ventilation performance and the quality of the intake air for the next cycle.
