The ERCO IL-116 was an American inline aircraft engine designed and built in the late 1930s. The type was not placed into series production due to competition from cheaper engines. Design and developmentIn late 1938, the Engineering and Research Corporation (ERCO) searched unsuccessfully for a suitable engine for its new "safe" airplane, the Ercoupe. ERCO hired Harold Morehouse, former engineer in charge of small engine design at Continental Motors, to design a new engine. He came up with the inverted, in-line IL-116, which provided good pilot visibility and enhanced aircraft streamlining. ERCO installed the IL-116 in the prototype Ercoupe Model 310 in 1939. The engine performed well, but ERCO discontinued it when Continental introduced the Continental A65 engine in 1940, which generated comparable horsepower at half the cost. ERCO manufactured parts for six IL-116s but built only three were built.
