MAN L21/31: Turbocharger

Written by

The turbocharger in the MAN L21/31 engine plays a crucial role in boosting engine performance by forcing additional air into the combustion chamber. This increases power output and fuel efficiency while reducing harmful emissions. Designed to operate under extreme heat and high speeds, the turbocharger must be precisely manufactured and regularly maintained to ensure long-lasting and reliable engine operation.

The joint ring bearing code number K 81259 is a sealing element designed for use with the screw plug K 81258 in the Sulzer ZV40/48 engine. Its primary function is to provide a leak-proof seal between the plug and the housing, ensuring that fluids such as oil or coolant remain contained under pressure. Manufactured from resilient and heat-resistant material, the joint ring is essential for maintaining the engine's operational integrity and avoiding performance issues caused by leaks or pressure loss.
