Weichai Engines Product advantages

  • More reliable-high configuration, low failure rate

Global procurement, select domestic and foreign famous suppliers for parts and components, effectively improve reliability and reduce failure rate.
The 93 sand dust filter adapts to various environments such as dusty and different soil quality, extending the maintenance period of the main filter element and reducing user operating costs.
The crankshaft is made of forged steel, which has higher strength.
Integrated fuel filter to facilitate vehicle layout and maintenance.
More efficient-strong power and high efficiency
  • High speed and constant power, low speed and large torque, good acceleration.

The torque reserve rate is as high as 25%, which is more suitable for the soil quality and agronomic requirements of different regions, and the work efficiency is high.
  • More economical-accurate fuel control, low fuel consumption

Optimize supercharger, fuel injector and calibration ECU data, through flexible control of fuel injection pressure, realize multiple injections, reduce engine fuel consumption and improve combustion efficiency
  • More comfortable-low vibration and noise 

Large-flow water pump and low-speed fan effectively reduce cab noise and avoid driving fatigue.
Controlled by the electronic control system, the fuel injection pressure is more stable, the response is fast, the fluctuation is small, and the combustion noise is low.
