Technology roadmap
- Electronically controlled high-pressure common-rail technology. Euro Stage IIIa/II emission standards.
Fuel filter system
- Three-stage fuel filter integrates three functions of electric pump oil, oil-water separation and fuel filtration, and shows high adaptability to fuel quality variation.
Fuel system
- Direct injection in cylinders improves combustion state and combustion efficiency, and effectively reduces engine fuel consumption, vibration and noise.
Intake system
- Air filter technology of special "Type 93 dust collecting filter" of Weichai delivers first-stage primary filter efficiency up to 93%, and reduces premature wear failure rate of engine “quadruple” kit (cylinder liner, piston, piston rings and piston pin) by more than 90%.
Cooling system
- Hyperboloid plastic fan effectively reduces engine radiation noise level while increasing heat dissipation efficiency, making driving more comfortable and secure.
Maintenance period
- Extra-long oil replacement interval: 500h, reducing use cost.
Environmental adaptability
- Meeting use in the environment of -35°C~50°C and altitude more than 5,000 meters.
