OSTI ID:5056620
A method of compressing the air supply to the carburetion system of a variable speed engine operated by the combustion of an air fuel mixture therein is described comprising: interconnecting the discharge outlet of a single stage, high speed centrifugal air compressor with the carburetion system of the engine, interconnecting the power output shaft of a variable speed electric motor with the impeller of the compressor through a differential transmission, the compressor having an inlet which opens into ambient atmosphere of the compressor for the intake of air therefrom, electrically activating the motor to drive the impeller and deliver compressed air to the carburetion system of the engine, the motor and the transmission being adapted to rotate the impeller within a range of 30,000 revolutions per minute or greater, and the speed of the motor being controlled so as to vary the speed of the impeller within the aforesaid range, commensurate with the speed of the engine.
