Ultra boost for economy: realizing a 60% downsized engine concept

Abstract

The paper discusses Ultra Boost for Economy, a collaborative project part-funded by the Technology Strategy Board, the UK’s innovation agency. ‘Ultraboost’ combines industry- and academia-wide expertise to demonstrate that it is possible to reduce engine capacity by 60% and still achieve the torque curve of a large naturally-aspirated engine, while encompassing the attributes necessary to employ such a concept in premium vehicles.
