venttiilijouset

Venttiilijouset, often translated as valve springs, are essential components in internal combustion engines. Their primary function is to close the engine's intake and exhaust valves quickly and effectively after they have been opened by the camshaft. This ensures proper sealing of the combustion chamber, which is critical for the engine's efficiency and performance.

The operation of a valve spring is based on storing and releasing mechanical energy. When the camshaft lobe pushes on the valve train mechanism, it forces the valve open against the spring's resistance. Once the camshaft lobe rotates away, the stored energy in the compressed valve spring is released, rapidly pushing the valve back into its closed position. This rapid closing action is crucial to prevent the valve from colliding with the piston, especially at high engine speeds.

Valve springs are typically made from high-strength steel alloys to withstand the repeated stress and high temperatures encountered within an engine. Their design, including wire diameter, coil count, and free length, is carefully engineered to achieve the desired spring rate and operating characteristics for a specific engine application. Factors such as engine speed, valve lift, and valve mass influence the choice of valve spring. Incorrect or worn valve springs can lead to various engine problems, including reduced power, misfires, and potential engine damage.
