170 series marine diesel engine
- Torque reserve 20%-34%
- Minimum fuel consumption 197g/kW.h
- Overhaul period 20000h
- Emissions meet IMO II/China I
Product advantages
Safe and reliable
- High-strength body, crankshaft and connecting rod to ensure that the diesel engine overhaul period is not less than 20000h
- Utilizing Weichai's global excellent supplier system, the quality of parts is reliable
- Large flow first filter and then cold lubrication system and efficient cooling system, modular design and one cylinder and one cover design, ensure the reliability of diesel engine parts and the convenience of use and maintenance
Powerful
- The high-pressure fuel pump, supercharger, fuel injector, valve and combustion chamber shape are reasonably optimized and matched, the power coverage is wide, and the torque reserve is large (greater than 30%), which makes its power index at an advantageous level among similar products.
Economical and fuel-efficient
- Four-valve technology, pulse conversion supercharger, large intake air, sufficient combustion, wide economic operating range, and the lowest fuel consumption rate can reach 197g/kW.h
Comfortable and environmentally friendly
- Strengthen the design of key components, so that the vibration index of the product has reached the A-level level of 11, and the noise index is 5 decibels lower than similar products, reaching the world's advanced level
- Emissions meet the requirements of IMO Tier II and China's first stage regulations
Practical
The unique Yuanhangbao monitoring system can monitor the speed, water temperature, oil temperature, oil pressure and other parameters of the diesel engine in real time. When the parameters of the diesel engine exceed the limit, it can automatically alarm and stop, and increase the wind and wave mode to ensure that the ship encounters key factors such as wind and waves. never stop
