Product advantage
High reliability
- The mean time between failures is 1000 hours, and the overhaul period is 10000 hours.
Modular design
- Parts are more than 20% less than similar products – integrated fuel filter module, integrated design of primary filter and fine filter;Filter module, oil filter, cooling, rotor filter, water filter integrated design One-piece cylinder head, compact design.
Excellent NVH performance
- The body is strong and vibration-less, greatly reducing noise.
- Rear gear chamber, high precision gear is used to shear gear, which provides stable operation and further reduces mechanical noise.
- Multiple injection technology for significant combustion noise reduction powerful power.
Ultra-low fuel consumption
- It uses an electronically controlled high-voltage common rail system, with high injection pressure, good atomization, and good economy.
- Powerful: High speed constant power, constant engine speed in common conditions.
