Automotive Engines for the 1980's

Abstract There are five major contenders to replace or supplement today's piston engine. Changing social requirements and new technological developments will lead to major changes in automotive power plants. This paper makes projections through the 1980's of the market penetration of Wankel, Stirling, Turbine, stratified charge and diesel engines for passenger car, heavy duty and small engine applications. These engines are compared on the basis of ten major selection parameters. Major factors affecting the rate of commercialization of new engines are reviewed including social, political and economic forces of change and historical perspective. Major inputs came from more than 60 worldwide in-depth interviews.
