Inside each marine diesel cylinder is a piston that slides up and down, and as it does so, it turns a crankshaft that's attached to a gearbox, which in turn powers the propellor in case of the main engine. The cylinders are also equipped with valves that let in air and fuel, and allow exhaust to escape.

The piston is a cylindrical engine component that slides back and forth in the cylinder bore by forces during the combustion process. The piston head is the top surface of the piston which is subjected to tremendous forces and heat during normal engine operation.

At Damen Schelde Parts we deliver, stock and supply pistons for main and auxiliary marine diesel engines from Sulzer, Wärtsilä, MAN B&W, Yanmar and Daihatsu.
