Product description
Safe and reliable
The overhaul period of high-strength engine block, crankshaft, connecting rod and cylinder head is 12000h
Rigorous and perfect test methods ensure the reliability of key parts and components
Strong power
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
Economical and fuel-efficient
Reasonable allocation of oil pump, turbocharger, air intake and exhaust system; low oil consumption under common working conditions; good economical nature
With shallow ω combustion chamber, the best cylinder clearance and swirl ratio, the fuel consumption rate is as low as 212g/kW•h
Comfortable and environmentally friendly
The NVH optimization for the whole engine effectively reduces vibration and noise
There is no IMO emission requirement
Strong practicability
LCD Internet instrument can be selected to monitor engine operating parameters in real time, so as to realize automatic alarm and stop
It is suitable for marine engines such as passenger ships, cargo ships, public service ships, fishing boats and tourist ships
