The first results of a fuel consumption study are given, in which the Stirling engine and automobile are treated as one system. Controlling the shaft power of the Stirling engine by varying the stroke of its pistons makes it possible to eliminate the torque converter and automatic transmission. A clutch and direct drive are used through-out the whole CVS speed range. The Philips computer program is used to optimize the engine for highest efficiency at a part load point. Constraints at low speeds and maximum power output are added. A layout of a transversely mounted engine is made, frontwheel drin wheel driving a 3500 lb automobile, using only existing technology and experience. The accessories of the 4-215 and the 4-98 engines were scaled to fit this application. Using Ford Motor Company simulation programs, a diesel fuel economy of 40 MPG is predicted for the Metro-High-way cycle. This high economy further enhances the favorable emission characteristics of the engine.
