ABSTRACT:
A turbocharger drive system associated with an internal combustion engine includes a plurality of turbochargers drivable by exhaust gases from the engine, a plurality or rotary electric machines mounted on the rotatable shafts, respectively, of the turbochargers and operable as electric motors or generators, and a single rotary electric machine coupled to the rotatable shaft of the engine. When the engine rotates at a low speed and under a high load, the rotary electric machine coupled to the engine shaft operates as an electric generator to generate electric power to drive the rotary electric machines mounted on the turbocharger shafts as electric motors, so that the boost pressure is increased to increase the output power of the engine. As the temperature in the combustion chambers rises because of the increased output power of the engine, the timing for supplying fuel into the combustion chambers is delayed to normalize the timing to start burning fuel, which would otherwise be advanced.
