Continental O-470 is a series of air-cooled six-cylinder boxer engines that was specially developed for use in small aircraft by the American manufacturer Continental Motors . The engines were produced both as carburetor models (type designation O-) and as injection engines (type designation IO-).

The series also includes the models E165 , E185 , E225 , E260 and various special models. It was produced from 1950 to 1986.

construction and development

The first engine in the series was the E165 with a displacement of 7.7 liters and an output of 165 hp (121 kW). It was also the first engine in Continental's E series. Later models were given the designation E185 with 185 hp (136 kW) and E225 with 225 hp (165 kW). After the US military gave these three engines of the series the designation O-470, the company adopted the designation for all future models.

The O-470 series covers a wide range of outputs between 213 hp (157 kW) and 260 hp (191 kW). Development of the first engines began in the late 1940s. The first type certification under the US Civil Air Regulations was applied for on October 23, 1950 and issued January 19, 1951.
