Product advantages

The WEICHAI Landking engine features compact structure and meets the Euro V and Euro VI emission requirements.

Comfort: The customized development of NVH ensures low noise and vibration.

Reliable

The standard WCBS has a braking power up to 263 kW.

B10 life is greater than 1,000,000 km.

Better economy

The speed that can achieve minimum fuel consumption covers the whole working speed range.

The WEICHAI ECU control system improves driver’s shift schedule and thus reduces fuel consumption.

The engine speed matching point for the same vehicle speed is lowered by 200 r/min, reducing frictional work and fuel consumption.

High configuration

The lightweight and modular design of the engine significantly reduces the weight of the engine and reduces the number of peripheral parts.
