The guide piston for the fuel injection pump (code K 55013) plays a vital role in maintaining precise fuel delivery in the Sulzer ZV40/48 engine. This component ensures the controlled movement of the injection pump’s internal mechanism, optimizing fuel flow and combustion efficiency. Manufactured from high-quality, wear-resistant materials, the guide piston is designed to endure high pressures and continuous operation. Regular inspection and proper lubrication are necessary to prevent wear and ensure consistent engine performance, contributing to fuel efficiency and reliable operation in marine and industrial applications.
