PRESENT AND FUTURE TRENDS IN AUTO FUEL CONSUMPTION

PRESENT AND FUTURE MILEAGE PATTERNS AND THE EFFECT OF EMISSION CONTROL MEASURES, PROSPECTS FOR ALTERNATIVE POWER PLANTS, THE POSSIBILITIES FOR SYNTHETIC FUELS, AND THE EFFECT ON AUTO FUEL CONSUMPTION OF COMPONENTS AND ACCESSORIES ARE DISCUSSED. PROJECTIONS ARE PRESENTED OF THE FUEL DEMAND IN 1985, BASED ON CALCULATIONS MADE FOR SYSTEMS USING UNLEADED 91 RON AND 83 MON FUEL IN LIGHT DUTY VEHICLES. ALTERNATIVES WHICH WOULD LOWER THE PROJECTED VALUES ARE SUGGESTED. A RELAXATION OF SOME OF THE ENVIRONMENTAL REQUIREMENTS AND THE POPULARIZATION OF SMALL CARS ARE CONSIDERED. THE FUEL ECONOMY OF PRESENT AND FUTURE POWER PLANTS AND A COMPARISON OF THE ROAD LOAD EFFICIENCES OF THE SAME VEHICLES OVER THE FEDERAL DRIVING CYCLE ARE ILLUSTRATED. THE FUEL ECONOMY AND THERMAL EFFICIENCY OF THE STRATFIELD CHARGE ENGINE, THE DIESEL POWER PLANT, THE WANKEL, STIRLING, BRAYTON AND RANKINE SYSTEMS ARE DISCUSSED. THE EFFECT OF SIZE, WEIGHT, TRANSMISSION AND ACCESSORIES ON FUEL CONSUMPTION ARE SUMMARIZED. FUELS SUCH AS SYNTHETIC GASOLINE, LIQUID HYDROCARBONS, METHANE, METHANOL, ETHANOL, HYDROGEN, AMMONIA, AND HYDRAZINE ARE CONSIDERED PROMISING, AND THE HYDROGEN VEHICLE, IT IS THOUGHT, WILL PROVIDE THE COMPLETE ANSWER TO THE PRESENT SUPPLY AND POLLUTION PROBLEMS.
