Design and development

The first engine in this series was the E165, a 471 cubic inch (7.8 L) engine producing 165 hp (123 kW) and the first of Continental's "E" series engines.

Later versions were given the company designation of E185 (185 hp (138 kW) continuous) and E225 (225 hp (168 kW)).

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.

The O-470 family of engines covers a range from 213 hp (159 kW) to 260 hp (194 kW).

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.
