ME011143
Piston
Mitsubishi FUSO®

A piston is a cylindrical component of an engine that moves up and down in a cylinder bore. It is typically made of aluminum alloy or cast iron and is responsible for transferring the force generated by the combustion of fuel to the crankshaft. The piston has several important features, including the crown, which is the top surface that receives the force of combustion, and the skirt, which contacts the cylinder wall to maintain proper alignment. The piston also has rings that seal against the cylinder wall to prevent leakage of combustion gases and oil into the combustion chamber. The ME011143 is a specific part number for a piston used in certain models of trucks.
