Sisselaskeklapp

Sisselaskeklapp, also known as an intake valve, is a crucial component in internal combustion engines. Its primary function is to control the flow of the air-fuel mixture into the engine's combustion chamber during the intake stroke. The valve operates by opening and closing at precise moments in the engine cycle, synchronized with the piston's movement and the camshaft.

When the piston moves downwards, creating a vacuum within the cylinder, the sisselaskeklapp opens. This allows the pre-mixed fuel and air, or just air in direct injection systems, to be drawn into the combustion chamber. As the piston begins its upward movement, the sisselaskeklapp closes, sealing the chamber and preparing it for compression and subsequent ignition.

The design and material of the sisselaskeklapp are critical for engine performance and durability. They are typically made from hardened steel alloys to withstand high temperatures and pressures. The sealing surface of the valve and its corresponding seat must be precisely machined to ensure a tight seal, preventing leakage of the mixture. Multiple intake valves per cylinder can be employed to improve volumetric efficiency and power output. The proper functioning of the sisselaskeklapp is essential for efficient combustion, optimal engine power, and reduced emissions.
