The fuel injection pump (code K 55000) is a critical component in the Sulzer ZV40/48 engine, responsible for delivering precise amounts of fuel to the combustion chamber at the correct pressure and timing. This ensures efficient fuel atomization, optimal engine performance, and reduced emissions. Designed for durability and precision, the pump operates under high-pressure conditions and must be regularly maintained to prevent wear and fuel delivery inconsistencies. Routine inspections and servicing of the fuel injection pump are essential for maintaining fuel efficiency, engine reliability, and long-term operational stability in marine and industrial applications.
