Abstract
The motor-assisted variable geometry turbocharging system has a motor to add power to the turbocharger rotating assembly, especially at low exhaust gas volume. Additionally, the system includes a control over compressor air inlet direction, and/or control of exhaust gas to a two-volute expander. These are individually controlled, or controlled in combination, to enhance turbocharged engine performance. In a preferred embodiment, the system comprises an electric motor, mounted directly within the turbocharger main housing, variable pre-whirl vanes mounted upstream of the turbocharger compressor, and a diverter valve in the exhaust piping upstream of a divided turbine volute.
