Technical route
- Electronically controlled high-pressure common rail plus SCR technology to meet China's five-stage road emissions.
Fuel filter system
- Three-stage fuel filter, good oil adaptability, and improved reliability.
Fuel system
- Direct injection in the cylinder to improve combustion efficiency, strong power and good economy.
Transmission system
- A variety of optional rear power output, maximum torque 1000N.m, flange output: 1:1/1:1.16 speed ratio; SAE internal spline output: 9 teeth/11 teeth/14 teeth.
Front gear train
- Automatic tensioning of the front wheel train, belt life of 10000h, optional crankshaft fan or 272mm height bracket fan.
Maintenance period
- The long oil change period of 500h reduces the use cost.
Environmental adaptability
- It can meet the environment of -35℃～50℃.
