Sisselaskeklappide

Sisselaskeklappide, or intake valves, are crucial components within the internal combustion engine. Their primary function is to control the flow of the air-fuel mixture into the engine cylinders. During the intake stroke of the engine cycle, the piston moves downwards, creating a vacuum within the cylinder. This vacuum draws the air-fuel mixture through the open sisselaskeklapp.

The sisselaskeklapp is a precisely engineered poppet valve. It consists of a head and a stem. The head is designed to seal against a valve seat within the cylinder head, preventing any flow when closed. The stem extends through a guide and is connected to the valve train, which includes components like camshafts, rocker arms, and springs. These components are responsible for opening and closing the valve at the correct time in relation to the piston's movement and the engine's rotational speed.

The timing of the sisselaskeklapp opening and closing is critical for optimal engine performance, fuel efficiency, and emissions control. Modern engines utilize sophisticated valve timing systems to adjust the valve events dynamically. The number of sisselaskeklappide per cylinder varies, with most engines having at least one, and performance-oriented engines often featuring two or even four intake valves per cylinder to improve airflow and volumetric efficiency. The material and design of the sisselaskeklapp are chosen to withstand high temperatures and pressures within the combustion chamber.
