The Sulzer ZV 40/48 engine relies on precision components like the elastic screw for the fuel injection pump, designated with code number K 55042, to ensure optimal performance. This elastic screw plays a critical role in maintaining the precise alignment and secure fastening of the fuel injection pump, which is essential for efficient fuel delivery and combustion. Its elasticity helps absorb vibrations and reduce stress on the pump, contributing to smoother engine operation, improved durability, and consistent performance in demanding marine or industrial applications.
