CORRELATION OF THE CHARACTERISTICS OF SINGLE-CYLINDER AND FLIGHT ENGINES IN TESTS OF HIGH-PERFORMANCE FUELS IN AN AIR-COOLED ENGINEnⅡ - KNOCK-LIMITED CHARGE-AIR FLOW AND CYLINDER TEMPERATURES

摘要

An investigation was conducted to correlate the knock-limited performance of flight and single-cylinder engines under a variety of operating conditions. Knock-limited performance of 28-R, triptane blend, and xylidine blend was determined on a full-scale air-cooled single cylinder mounted on a CDS crankcase. The inlet-air temperatures were such that the mixture temperatures were the same as the multicylinder engine with high and low blower ratios.
