Piston for Scania

The piston with part number 1393166 functions as a primary moving component within Scania engines. It travels within the cylinder bore to compress the air-fuel mixture and receives the force generated by the combustion process. This force is then transferred to the crankshaft via the connecting rod to produce mechanical output. The component features integrated grooves for piston rings, which maintain the seal of the combustion chamber and regulate oil film distribution along the cylinder wall.

This component is engineered to meet the specific dimensional and tolerance requirements of Scania engine blocks. It ensures proper clearance within the cylinder liner to manage thermal expansion and mechanical friction during operation. Accurate fitment of this assembly is necessary for maintaining compression ratios and overall engine efficiency in heavy machinery applications.

In internal combustion engines, pistons serve as the moving boundary of the combustion chamber. They must withstand the cyclic pressure loads and thermal cycles inherent in the power stroke. By housing the piston rings, they also act as a heat transfer path, moving thermal energy from the combustion gases to the cylinder walls and the cooling system.
