GM REVEALS 'HIDDEN' STEAM AND TURBINE RESEARCH

THE HISTORY IS REVIEWED OF GAS TURBINE DEVELOPMENT AT GENERAL MOTORS CORPORATION. GENERAL MOTORS' EXPERIENCE WITH STEAM VEHICLES DATES FROM 1929. A SIXTH-GENERATION REGENERATIVE TURBINE IS SLATED TO BE PRODUCED BY THE COMPANY'S DIESEL ENGINE DIVISION IN 1971. RECIRCULATING EXHAUST HEAT TO PREHEAT INTAKE AIR WILL IMPROVE FUEL ECONOMY, MAKING IT COMPARABLE TO GAS AND DIESEL ENGINES IN TRUCK, BUS, AND INDUSTRIAL USES. HOWEVER, PRODUCTION ENGINEERING AND OPERATING DATA SHOW IT IS NOT COMPETITIVE IN COST, SIZE, AND OPERATION FOR PASSENGER CAR APPLICATION. TWO TYPES OF STEAM ENGINES HAVE BEEN FITTED WHICH ARE PICTURED AND DISCUSSED. THE LATEST STEAMER DEVELOPED BY GM IS A SOPHISTICATED 160-HP MACHINE INSTALLED IN THE 1969 PONTIAC GRAND PRIX. VIRTUALLY AUTOMATIC OPERATION IS OBTAINED BY USE OF SOLID-STATE CONTROLS AND LOGIC CIRCUITS FOR STEAM SYSTEM OPERATION. ALTHOUGH THE INSTALLED WEIGHT OF THIS POWERPLANT IS 204 KG MORE THAN THE INTERNAL COMBUSTION ENGINE IT REPLACED, IT PRODUCES LESS THAN HALF THE HORSEPOWER. ALSO, IT IS CONSIDERABLY LARGER. APPARENTLY THIS IS THE FIRST STEAM-POWERED AUTO TO COMPLY FULLY WITH THE CURRENT ASME BOILER CODE.
