An engine-and-electric-machine assembly is provided that includes an engine and an electric machine, a crankshaft being provided in the engine, the crankshaft including a main body and an extension section that extends out to the exterior of the engine, the extension section forming a rotation shaft of the electric machine, and a rotor of the electric machine being mounted on the extension section. Moreover, a terminal of the rotation shaft is connected to a coolant pump, a rotor of the coolant pump is mounted to the rotation shaft, and while the rotation shaft is rotating the rotation shaft drives the coolant pump to provide coolant to the electric machine. By connecting the rotation shaft of the electric machine to the coolant pump, the assembly enables the pump to be highly integrated into the system and reduce manufacturing cost.
