WP10 diesel truck engine has a broad range of big torque, and its fuel economy is fine at all conditions. The performance has been improved obviously and the fuel consumption decreased by more than 10% after optimization for combustion
Wide power range(336-480kW) and high torque back up (up to 30%) of the engine insure the vehicle working
normally under all kinds of conditions.
High rigidity of cylinder block with special framed main bearing structure, strict quality management system and global sourcing for major components insure the reliability of the engine. The target of durability reaches l0000h without major overhaul.
One cylinder one head is convenient for maintenance. Major parts of WD615 and WD12 engines are interchangeable thus lower the running costs. Outline dimensions of the whole series are of the same which can make the design and manufacture easier.
By optimizing of the combustion, intake and fuel supply systems of the engine, emissions of exhaust pollutants from any Weichai Power product for vehicle are prior to the limit of Euro II regulation and has the potential for meeting Euro III.
