Weichai WP7 series engines for construction machinery are new high-end diesel engines independently developed by Weichai in 2007. Displacement: 7.47L. Power range: 162-199kW. Electronically controlled common-rail fuel injection system is a standard configuration item. Four-valve integral cylinder head, gantry-type engine body, and rear mounted gear chamber are used. Power, fuel consumption, torque, etc. and other main technical indicators all reach the advanced level of diesel engines having the same displacement. Euro Stage IIIa emission standard. Equipped with a suitable after-treatment system to meet higher emission standard.
