Dynamic downsizing gasoline demonstrator

48 V mild-hybrid architectures, currently receiving increasing attention, pave the way for increased levels of engine downsizing. This is facilitated through the ability to achieve a virtually instantaneous and continuous supply of boost air for the engine, even at low engine speeds, via the addition of an electrically powered supercharger (eSupercharger). The ability to increase the level of engine downsizing, while retaining good fuel efficiency across the majority of the engine operating map, would provide manufacturers with a transferable, and scalable, means for meeting these stringent new CO2 targets across their entire fleet.
