The objective of this program is to evolve and define an accessory drive system that will minimize system power consumption of driven accessories on an internal combustion engine in a passenger automobile. The initial program phases established concept feasibility, determined potential fuel savings, and selected a drive system design for concept mechanization. The present Phase IV carries the program through prototype fabrication and bench, engine, and vehicle tests. The final program objective is a detail drive system design and a demonstrated overall vehicle fuel savings potential. The major technical accomplishments during this reporting period were: hydromechanical and mechanical variable-ratio belt …

Description
The objective of this program is to evolve and define an accessory drive system that will minimize system power consumption of driven accessories on an internal combustion engine in a passenger automobile. The initial program phases established concept feasibility, determined potential fuel savings, and selected a drive system design for concept mechanization. The present Phase IV carries the program through prototype fabrication and bench, engine, and vehicle tests. The final program objective is a detail drive system design and a demonstrated overall vehicle fuel savings potential. The major technical accomplishments during this reporting period were: hydromechanical and mechanical variable-ratio belt drive fabrications completed; compact vehicle fuel economy analysis completed; initial engine check runs for both drive systems were completed; mechanical drive system development and performance mapping was initiated; hydromechanical drive system development tests and modifications were initiated; the hydromechanical drive system installation into the test vehicle was completed; the engine/dynamometer test rig, including accessory load simulators, was completed; and the basic test vehicle instrumentation was completed.
