Technology roadmap
- Electronically controlled high-pressure common-rail technology. Euro Stage IIIa emission standard. Small change to subsequent harmful emissions reduction.
Fuel system
- Special “three-stage auxiliary filter element” of Weichai completely removes water and impurities in the fuel, and greatly reduces fuel system failure rate.
Improved comfort
- Advanced product platform. Low noise level. Excellent sound quality. High vehicle comfort.
High reliability
- High reliability of product. B10 life is up to 25,000 hours.
Long maintenance period
- Extra-long oil replacement interval: 500h. Oil filter and fuel filter only need to replace filter paper. Repair and maintenance costs of vehicle are low.
Environmental adaptability
- Meeting use in the environment of -25°C~50°C and altitude 2,000 meters.
