Valve for Scania D13A/ C

The valve, part number 7421428655, is a component engineered for Scania D13A and D13C series engines. It functions within the cylinder head assembly to manage the intake of air or the exhaust of combustion gases. By opening and closing at precise intervals during the engine cycle, this component ensures the proper movement of gases into and out of the combustion chamber.

This part is compatible with several engine configurations, including the Scania D13A/C, D13A/C EURO, D13K 25º/EURO 5-6, and D13K EURO models. It is designed to meet the specific fitment requirements of these engine series, maintaining the necessary seal for combustion pressure and gas flow management.

In internal combustion engines, valves are tasked with the timing of gas exchange. Intake valves allow the entry of air for the combustion process, while exhaust valves facilitate the removal of spent gases after the power stroke. Proper seating and timing of these valves are necessary to maintain compression, which directly influences the power output and operational efficiency of the machinery.
