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
- Customized design for lower fuel consumption
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
