Valve for Scania D12A

The valve, identified by part number 20450002, is engineered for the Scania D12A, D12C, and D12D engine series. This component is integrated into the cylinder head assembly to regulate the movement of gases into and out of the combustion chamber. By managing these cycles, the valve ensures the engine maintains the necessary compression and airflow for proper operation.

This component is compatible with Scania D12A, D12C, and D12D engine models. It is designed to meet the specific fitment requirements of these diesel power units, ensuring alignment with the valve train and cylinder head geometry.

In an internal combustion engine, valves are responsible for the timing of air intake and exhaust gas discharge. Intake valves allow air to enter the combustion chamber, while exhaust valves permit the exit of burned gases after the power stroke. Precise synchronization of these valves is necessary for the engine to maintain power output, fuel efficiency, and emission standards. Proper seating of the valve against the valve seat is required to prevent loss of compression during the combustion process.
