Continental O-470

From PlaneSpottingWorld, for aviation fans everywhere

The Continental O-470 engine is a family of carbureted six cylinder, horizontally opposed, air-cooled aircraft engines that was developed especially for use in light aircraft by Continental Motors. The family includes the E165, E185 and the E225 engines. It has been in production since 1950.[1][2][3][4][5][6][7]

The IO-470 is a fuel injected version of the same basic engine.[2][4]

Design and development

The first engine in this series was the E165, a 471 cubic inch (7.8 L) engine producing Template:Convert and the first of Continental's "E" series engines. Later versions were given the company designation of E185 (Template:Convert continuous) and E225 (Template:Convert). When the US military gave them all the designation of O-470 the company adopted the designation and future models were known as Continental O-470s.[5]

The O-470 family of engines covers a range from Template:Convert to Template:Convert. The engines were first developed in the late 1940s and certification was applied for on 23 October 1950 on the regulatory basis of Part 13 of the US Civil Air Regulations effective August 1, 1949 as amended by 13-1. The first O-470 model was certified on 19 January 1951.[1][2][3][4]
