Tappet for Scania

The tappet, part number 1116635, functions within the valve train of a Scania internal combustion engine. It serves to transfer the mechanical motion from the camshaft to the intake and exhaust valves. By maintaining this connection, the component ensures that valves open and close at the correct intervals and with the required lift for the combustion cycle. This synchronization is necessary for the volumetric efficiency of the engine and the regulation of air and fuel flow through the cylinders.

This component is engineered for use in various Scania engines found in trucks, buses, and industrial machinery. The part operates in direct contact with the camshaft lobes and the valve stems to facilitate the valve train movement. Proper function of the tappet helps maintain engine compression and power output while preventing irregular valve timing that can lead to mechanical noise or damage to the camshaft and surrounding valve train components.
