WP12 is a Weichai Blue Power product power range 276-360kW and a maximum torque of 2300N•m, which Euro II/III/IV/V/VI emission standards. Applied in a 6 × 4 medium and long distance composite transport tow tractor.

High reliability
Frame block, dry cylinder liner, high engine reinforcement, over 45,000 hours of bench test cumulatively, and over 50 million kilometers of whole vehicle road test
Excellent NVH performance
Idle noise 81dB(A) - the body is drum-shaped skirt design, with high body strength and low vibration, which greatly reduces noise
Rear gear chamber, high precision gear is used to shear gear, which provides stable operation and further reduces mechanical noise
Multiple injection technology to reduce combustion noise significantly
Ultra-low fuel consumption
The lowest fuel consumption rate of 183g/(kW•h) is achieved by optimizing combustion, improving camshaft profile, and high efficiency supercharger, using multiple high efficiency components. The low-speed fuel consumption area covers the usual conditions of 1000-1400r/min, making it more economical and fuel-efficient
Powerful
Maximum torque 2300N•mfor superior acceleration
A smaller rear axle ratio can be selected for power, up to 120km/h
Altitude capability
Underated power at 3500m altitude and less than 5% power loss at 4100m rated speed for extreme environmental suitability
