Abstract
Octane requirement and road octane rating studies were conducted in two production turbocharged automotive gasoline engines -- one aircooled and the other liquid cooled.
Road octane ratings obtained by the Modified Borderline Method compared reasonably well with corresponding road octane ratings obtained using an octane requirement approach and were considered representative. Fuel factors, important as regards antiknock performance in naturally aspirated engines were directionally similar in importance in the turbocharged engines. Sensitivity had less effect on fuel antiknock performance under high speed supercharge conditions than might be expected under naturally aspirated conditions.
Details of the tests on the 1962 turbocharged Corvair and Oldsmobile F-85 are presented.
