SUPERCHARGER SYSTEM FOR STOP/START HYBRID OPERATION OF AN INTERNAL COMBUSTION ENGINE

摘要

A supercharger system for supplying compressed air to an internal combustion engine, including a supercharger; an active clutch operationally connected to the engine that can be selectively opened and closed; a motor/generator operationally connected to the supercharger; an energy storage device operationally connected to the motor/generator; and a secondary drive element connecting the supercharger, the clutch, and the motor/generator to permit synchronous rotation thereof, the clutch being disposed either directly on the crankshaft of the engine or on a primary accessory drive element of the engine. Other devices such as an HVAC compressor may be included optionally on the secondary drive element. At low engine speeds, the supercharger is powered by the motor/generator; at high engine speeds, by the engine.
