Abstract
The invention relates to a vehicle engine system. The engine system includes an internal combustion engine, a cooler of a cooling circuit, an electric generator driven by the engine from a side of the engine which is other than that which faces the cooler, and a fan for moving air through the cooler, all disposed in an engine compartment. An electric motor is powered by the generator and mechanically drives the fan through an output shaft which is mechanically connected to the fan. The output shaft of the motor is disposed in the engine compartment near a mechanical power take-off of the engine. The mechanical power take-off includes a belt pulley connected to a free end of an engine crankshaft.
