Two-stroke/four-stroke multicylinder gasoline engine for downsizing applications

Abstract

Following the great public interest aroused by the „2/4-sight“ concept and the successful completion of the fundamental investigations on the testbed, Ricardo is now starting work on the „2/4-car“ project. This project aims to prove the combinability of two- and four-stroke operation in a single internal combustion engine within a demonstrator vehicle. The additional degree of freedom of the engine operating mode opens the potential for down sizing beyond conventional technical limits, enabling a competitive CO2/cost trade-off compared to future diesel powertrains.
