High reliability
- The mean time between failures is 1000 hours, and the overhaul period is 5000 hours.
Modular design
- Compared with similar products, the parts and components are reduced by more than 20%-integrated fuel filter module, integrated design of coarse filter and fine filter.
- Machine filter module, integrated design of oil filter, cooling, rotor filter and water filter.
- Integral cylinder head, compact design.
Excellent NVH performance
- High body strength, low vibration, greatly reducing noise.
- The rear gear room uses high-precision gears to cut the gears, stable operation and further reduction of mechanical noise.
- Multi-injection technology greatly reduces combustion noise.
Ultra low fuel consumption
- Using electronically controlled high-pressure common rail system, high injection pressure, good atomization, and excellent economy.
Powerful
-
- High speed and constant power, the engine speed is stable and does not drop in the common working conditions of the harvester.
- Good adaptability.
