Compressor drive for IC engine has a variable epicyclic gearing between the compressor and the engine and a synchronous electric motor

摘要

A mechanical compressor drive for enhancing the performance of an IC engine has a mechanical design with an epicyclic gearing (16, 18) between the compressor (10), the engine (12) and a synchronous electric motor (34) to vary the compressing rate to match the engine requirements, from idling speed to maximum output. The three connections to the epicyclic gearing are fitted with clutches (44). The sun wheel is connected to the electric motor, the planetary cage is connected to the compressor and the hollow ring gear is connected to the crankshaft of the engine via a belt and pulley drive.
