ABSTRACT:
An improved method and apparatus for increasing the charge air supply to an internal combustion engine throughout the engine operating range, and more particularly, at low engine speeds, and combines controlled two-stage compression of charge air with improved turbocharger operation to achieve a particularly flexible and effective supercharging system. Such supercharging systems are provided by a first charge air compressor driven by an electric motor, a second charge air compressor driven by an exhaust gas driven turbine, gas control means for the supercharging system and a control for the electric motor-driven compressor and gas control means. Preferably, the turbine-driven charge air compressor is also driven by a second electric motor operated by the control, and the gas control means comprises an exhaust gas diverter valve for the exhaust gas turbine inlet and pre-whirl vanes for the turbine-driven compressor inlet, both operated by the control.
