Two modified fuel-injection systems, a drilled-inducer type and a spinner type, that prevent serious fuel-evaporation icing were installed on a V-type, liquid-cooled aircraft engine and a preliminary investigation was conducted to determine the effect on engine operating characteristics. The spinner system was also ground- and flight-tested on a twin-engine fighter airplane. Flight measurements of cylinder-head temperatures over a range of fuel-air ratios and engine power conditions were made at an altitude of approximately 10,000 feet.
