STUDY ON REDUCTION OF AUTOMOTIVE ACCESSORY POWER REQUIREMENTS: FINAL EXECUTIVE SUMMARY. FINAL REPORT, JUNE 1974-JUNE 1978

This program was directed toward near-term automotive accessory optimization and toward evaluation of accessory systems for advanced Stirling and turbine automotive and truck propulsion engines. The objective was to define, evaluate and develop automotive accessory systems to minimize engine power consumption and significantly improve fuel economy. The program phases included: the conceptual, preliminary and detail design of automotive accessory systems and accessory drives; fabrication, assembly and laboratory testing of such systems and drives; vehicle/driving cycle energy source evaluation for accessory power augmentation, hybrid drive concept study, and an automotive air conditioning concept study for maximum required performance and minimum fuel consumption; and definition of automotive Stirling and gas turbine accessory requirements. Data from these studies are presented. It is concluded that equipping the 1979 US intermediate vehicle population with accessory speed control devices would conserve 69,000 bbl/d of fuel. If modified to take full advantage of energy reclamation and advanced accessory designs, the fuel savings could be as high as 150,000 bbl/d. If the entire US automotive population, with full accessory arrays, were equipped with accessory speed control devices, fuel conservation in the range of 180,000 to 400,000 bbl/d would be possible. The advanced accessory system technology discussed herein should be applied concurrently with new engine development to produce effective and efficient systems that maximize fuel economy potential.
