STIRLING ENGINES FOR LIGHT AND MEDIUM DUTY AUTOMOTIVE APPLICATIONS

A 75 kW four-cylinder double-acting Stirling engine with multifuel capability is described which provides extremely low emission levels and engine efficiency equal to or better than that of a diesel engine at slightly higher manufacturing cost. The 75 kW engine and an eight-cylinder version (two 75 kW modules in line) are scheduled for market introduction in 1985. The current status of United Stirling engine development and vehicle installation (Opel Record passenger car, Volvo delivery truck) is reviewed, and potential improvements in fuel economy are outlined. Near-term applications of this Stirling engine in low-emission vehicles for use in confined spaces or in an urban environment (e.g. underground mining equipment, forklift trucks, and city buses) are indicated. Emissions are compared to those of corresponding diesel engines.
