Supercharging i.c. engines

The engine is responsive to an engine power demand and is operable over a range of engine speeds to provide an engine power output in response to the engine power demand. The engine comprises: one or more combustion chambers; an air inlet for admitting air into the combustion chambers; a compressor...

Zusammenfassung:	The engine is responsive to an engine power demand and is operable over a range of engine speeds to provide an engine power output in response to the engine power demand. The engine comprises: one or more combustion chambers; an air inlet for admitting air into the combustion chambers; a compressor for compressing said air admitted into the combustion chambers in order to boost engine power output (SCB); a compressor driver by which the compressor is driven when the engine power demand is relatively high and deactivated when the engine power demand is relatively low; an engine controller responsive to the engine power demand in order to control engine power output, said engine power output in the absence of the compressor power boost (SCB) peaking at a moderate engine speed. According to one aspect of the invention, the engine controller enables use of the compressor driver when the engine speed is relatively low or moderate and disables use of the compressor when engine speed is relatively high. According to another aspect of the invention, the engine controller enables use of the compressor driver only in such a way that the engine power output with the compressor power boost (SCB) , peaks at an engine speed less than said moderate engine speed.
