imuventtiilejä

Imuventtiilejä, often translated as intake valves, are crucial components in internal combustion engines. Their primary function is to control the flow of the air-fuel mixture or simply air into the engine's combustion chamber.

These valves are typically located in the cylinder head, opposite the exhaust valves. When the piston moves downwards during the intake stroke, the intake valve opens, allowing the charge to enter the cylinder. As the piston moves upwards, the intake valve closes, sealing the combustion chamber for the compression and power strokes.

Imuventtiilejä are actuated by the camshaft, which is synchronized with the crankshaft. The shape and size of the intake valve, as well as the timing of its opening and closing, significantly impact the engine's performance, efficiency, and emissions. Larger valves generally allow for a greater volume of charge to enter, potentially increasing power output.

The material used for imuventtiilejä is usually a strong, heat-resistant alloy to withstand the extreme temperatures and pressures within the engine. They are designed to be durable and operate reliably for extended periods. Wear and tear on the valve seat or the valve itself can lead to compression loss and reduced engine performance.
