The overhaul period of high-strength engine block, crankshaft, connecting rod and cylinder head is 12000h.
The high-quality suppliers of Weichai system are used. It is developed according to the high requirements of large displacement engines for reliability. Rigorous and perfect test methods ensure the reliability of key parts and component.
The torque reserve is as high as 20%-35%,the range of large torque section is wide, and the ships equipped with the engine will have good acceleration.
Reasonable allocation of oil pump, turbocharger, air intake and exhaust system; low oil consumption under common working conditions; good economical nature.
With shallow combustion chamber, the best cylinder clearance and swirl ratio, the fuel consumption rate is as low as 195g/kW•h.
The NVH optimization for the whole engine effectively reduces vibration and noise. There is no IMO emission requirement.
