Product advantages

Air filter system

  • Weichai’s patented "93% dust filter” is used, such that the first-level coarse filtration efficiency is as high as 93%, prolonging the replacement period of the filter element and reducing the early wear rate of the engine.

    Cooling system

  • The hyperboloidal fan and the high-capacity water pump guarantee low noise and power consumption.

    Long maintenance period

  • 500h oil change period is ensured, reducing the usage cost.

    Environmental adaptability

  • The engine functions normally at -35°C ~ 50°C.
