Valve for Scania

The valve, part number 105-35654, functions as a critical component within the distribution system of Scania engines. In an internal combustion engine, valves are responsible for controlling the intake of the air-fuel mixture or the exhaust of combustion gases from the cylinders. This component operates by sealing against the valve seat in the cylinder head, while the stem moves through a guide to facilitate the timing of the gas exchange.

Precise dimensions and surface finish are required for this component to ensure a tight seal and smooth operation, which directly influences engine compression and combustion efficiency. The valve is engineered to withstand the operational temperatures and pressures present within the combustion chamber during the engine cycle.

Valves are mechanical components that open and close at specific intervals to manage the gas exchange process in an engine. By ensuring that the combustion chamber is properly sealed during the compression and power strokes, the valve helps maintain the power output and fuel efficiency of the machine. Regular maintenance and inspection of the valve train are necessary to prevent issues such as loss of compression or damage to internal engine components.
