Product description
Safe and reliable
- The safety factor of shafting parts is higher than the ship code standard, so as to ensure the safety and reliability of parts
- Side-pulling bolts are arranged on engine block to ensure the optimal stress distribution of the engine block, so as to reduce the deformation of parts and improve the service life
- Replace the filter without stopping
Strong power
- High power, about 15% higher than similar products
- High explosive pressure, about 20% higher than similar products
- The maximum torque output can be maintained at 70%-100% rated speed, and the range of high torque speed is wide
Economical and fuel-efficient
- Through simulation optimization and experimental verification, the shapes of high injection pressure fuel system, intake port and combustion chamber have reached the world advanced level. The intake air is sufficient, and fuel consumption is about 7% lower than that of similar products
- Customized design for lower fuel consumption
Comfortable and environmentally friendly
- The pulse supercharging system is featured by good load response, fast acceleration and low smoke intensity
- IMO II emission requirements are met
Strong practicability
- Mature structure, modular design and strong maintainability
- Three-section connecting rod, convenient cylinder lifting, and convenient maintenance
- The maintenance workload is small, and the maintenance time is less
