Title: Study on reduction of accessory-horsepower requirements. Third quarterly progress report

Abstract

The objective of this study program is to minimize automotive accessory horsepower consumption, and thereby maximize overall vehicle fuel economy, by utilizing continuously variable speed drives or auxiliary power units (APUs) in a standard passenger automobile. As an aid to definitizing accessory performance, load requirements and fuel economy, a baseline vehicle has beeen established. This vehicle is a conventional intermediate size 5- or 6-passenger automobile with a 4.1 to 5.7 liter (250 to 350 cubic inch) displacement, spark ignition engine. Accessories to be considered are the alternator, power steering system, power brakes, air conditioner, cooling fan, water pump and emission control air pump. A program summary of major accomplishments is presented including: accessory drive devices analyses; vehicle computer model fuel economy analyses; improved accessory efficiency analysis; resized engine fuel economy analysis; accessory evaluation matrix completed; drive-systems trade-study completed and the prime concept presented; and variable-speed belt-drive concepts reviewed.
