Abstract
In an internal combustion engine and a method of operating the engine which comprises a compressor having an impeller disposed in a housing including a main inlet duct in which the impeller is supported and an additional inlet duct joining the main inlet duct in the area of the compressor impeller, and valving means for controlling the gas supply to the inlet ducts and an electric motor connected to the compressor impeller for rotation therewith so that the compressor is operable by the electric motor and by the pressure drop in the air intake line of the engine, a flywheel is coupled to the impeller for storing rotational energy when the impeller is driven by the intake gas and returning the energy to the impeller when the pressure drop collapses upon a sudden increase in the demand for engine power.
