- Scania
The engine valve with part number 21026535 is engineered for Scania internal combustion engines, which are commonly found in heavy-duty trucks, buses, and industrial machinery including cranes. This component manages the flow of gases into and out of the combustion chamber, regulating the intake of the air-fuel mixture and the expulsion of exhaust gases. Its precise design ensures a tight seal when closed to maintain cylinder compression and provides the necessary opening stroke to facilitate engine breathing.
This valve is compatible with various Scania engine configurations. It functions by reciprocating within the cylinder head, synchronized with the crankshaft and camshaft to open and close at specific intervals during the four-stroke cycle. By controlling these gas exchanges, the valve directly influences the volumetric efficiency and power output of the engine. Proper seating and movement of the valve are required to prevent compression loss and maintain the operational integrity of the combustion cycle.
