The piston, code P50602-03, is a high-performance component at the heart of the MAN L21/31 engine’s combustion cycle. Made from heat-resistant alloys, it endures explosive pressures and high temperatures while moving rapidly within the cylinder liner. Its carefully engineered crown shape maximizes combustion efficiency, while its light weight and strength reduce inertia and wear. Designed for long service life, this piston plays a key role in fuel efficiency, emission control, and overall engine performance.
