Technology roadmap
- Electronically controlled high-pressure common-rail technology contributes to high combustion efficiency, low noise level and low vibration intensity. Meeting Euro V emission standard.
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.
Lubrication system
- Remote transmitting oil filter effectively improves in-vehicle installation arrangement and adds convenience for repair and maintenance.
Intake 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.
Transmission system
- Rear mounted gear system and anti-gear gears design contributes to smooth operation and low noise level.
Improved comfort
- Unique "engine body vibration damper web plate” is a standard configuration item. Reasonable curved surface design and effective reinforced arrangement improve skirt stiffness.
- Reinforced oil sump, high strength, high modality, effectively suppresses radiation noise.
Maintenance period
- Extra-long oil replacement interval: 500h, reducing use cost.
Environmental adaptability
- Meeting use in the environment of -35°C~50°C.
