The cylinder liner has fire ring structure.The cylinder unit consists of cylinder head cylinder liner and connecting rod.After fixing the cylinder unit.it is mounted on the engine,it is fast and convenient in maintenacne.
3 Connecting rod
Connecting rod consists of connecting rod body,connecting rod marine head (upper and lower both).Decrease hoisting height to make crankshaft pin bigger and increase crankshaft strength.
4 Supercharged and intercooled system
MAN's advanced turbocharger is adopted to provide the best matching
Two-stage intercooled system is adopted in intake process to control air temperature more precisely and rapidly.
5 Fuel pump
Specialized unit pump producted by MAN is adpoted.
Adopting the "engine with no pipeline"design concept,oil pipeline is intergrated in the cylinder with no water pipeline.
7 Safety control system
