Truck Diesel Engines WP3.7/WP4.1

WP3.7/WP4.1 light engines have been developed with the outstanding resources consisting of platform R&D, power train, NVH and application engineering teams at Weichai's head office.

Excellent economy: The min. SFC is as low as 205g/kW•h and the fuel-saving range is extended to 1,100 - 2,400 RPM.

Dynamic performance: Extremely strong gradeability and overtaking capacity - For example, WP3.7 has the max. torque of 400 N•m, representing a torque reserve of up to 27%; Robust starting and acceleration - An optimized turbo charger provides large torque at low speed, or 350N•m@1,000 RPM.

NVH: A reinforced cylinder block of a gantry form and additional reinforcing plates for the engine body provide higher strength, reducing the noise by 0.7dB and vibration intensity by 10%. Helical gears of Grade 7 precision enables more accurate engagement, additionally decreasing the noise by 0.5dB.
