Downsized Engine optimised for CNG Operation

Zusammenfassung

Gasoline engine downsizing is already established as a technology to reduce automotive fleet CO₂ emissions. Further benefits are possible through more aggressive downsizing, however, the trade-off between the CO₂ reduction achieved and vehicle drive-ability limits the level of engine downsizing currently adopted [1]. The ability to maintain or 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 assisting in meeting these stringent new CO₂ targets across their entire fleet.
