Truck Diesel Engines WP3N
WP3N is Weichai's high-end Euro V-compliant model recently lauched to meet the new market environment. As the outcome of four years of development, it is based on integration of worldwide resources and a VM product introduced from Europe. The engine is suitable to high-end light trucks of mainstream makes, with the wheel base of 2.8m - 3.8m and wide, medium, and narrow bodies.
Economy : The standard configuration includes a silicon oil fan that saves oil by 3% as compared to a rigid one. The L/100km fuel consumption is 1L less than that of competitors.
Dynamic performance : A 13%-increase in low-speed torque provides more powerful starting and acceleration. Max.torque is 14% higher than comparably powerful competitors, resulting in enhanced gradeability and overloading capacity.
Reliability : The model has undergone strict tests and assessments on stands, under high and low temperature, on high altitude, and over revolving drums. All its mission-critical components asre proven to be highly reliable, with the B10 life as high as up to 800,000km.
NVH : With a high torque at low speed, the engine normally runs at lower speeds than those of its competitors. This avoids its range of high-frequency torsional oscillation and reduces its noise by 2dB. the NVH performance is better than that of its competitors, and the noise emitted during accleleration is 4dB (A) lower than that of its competitors.
