The **Continental IO-360** is a family of fuel-injected air-cooled, horizontally opposed six-cylinder aircraft engines manufactured by Continental Motors in the United States of America, now part of AVIC International since 2010.^{[1]}^{[2]}

The engine is available in both naturally aspirated, fuel injected **IO-360** models and turbocharged **TSIO-360** versions. It is also available in both left and right hand rotation versions for use on twin-engined aircraft.^{[3]}

There was no carbureted version of this engine, which would have been designation *O-360*, therefore the base model is the *IO-360*.^{[4]}^{[5]}

## History

The IO-360 was first certified by the Federal Aviation Administration on 15 May 1962 to the CAR 13 certification standard, effective June 15, 1956, as amended by 13-1 thru 13–3. The engine is produced by Continental under Production Certificate No. 508.^{[4]}

The turbocharged TSIO-360 series was first certified on 11 October 1966 to the Federal Aviation Regulations Part 33 standard effective February 1, 1965, as amended by 33–1. This series is manufactured under Production Certificate No. 7, except the TSIO-360-D which is under Production Certificate No. 508.^{[5]}
