Limits of engine downsizing for reduced fuel consumption

Orian Welling (Energy)

Engine downsizing through turbocharging and supercharging is a strategy to reduce fuel consumption of gasoline engines. The extent to which the strategy can be implemented is currently limited by an intermittent low speed pre-ignition which leads to “megaknock”, a high amplitude high peak pressure knocking behaviour which can cause engine damage in a single cycle. This talk explores the origins of this low speed pre-ignition and possible solutions.
