Abstract
A hybrid electric vehicle (10) includes an internal combustion engine (12) which drives a generator (20) to produce electrical energy for a traction motor (44) of the vehicle. The generator (20) is provided with a cooling air intake port (20i). A air mover or compressor (30) is driven from the engine (12) or from an auxiliary motor (84), to produce air under positive pressure. The air from the air mover (30) is coupled by air paths (60, 62, 64) to the cooling air input port (20i) of the generator (20) and to the combustion air aspiration or input port (16) of the engine (12). If the air mover serves the purpose of cooling the generator (20) and, if a non-positive-displacement pump, also provides an effect similar to turbocharging, and if a positive-displacement type, supercharges the engine (12).
