Technology roadmap
- Electronically controlled high-pressure common-rail system contributes to high combustion efficiency, low noise level and low vibration intensity.
Air filter system
- Patented "Type 93 dust collecting filter” of Weichai delivers first-stage primary filter efficiency up to 93%, extends filter replacement cycle and reduces premature wear failure rate of engine.
Cooling system
- Hyperboloid fan and high-flow pump; low noise level and low power consumption.
Long maintenance period
- Extra-long oil replacement interval: 500h, reducing use cost.
Environmental adaptability
- Meeting use in the environment of -35°C~50°C.
