# Continental IO-360

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]

Type | Piston aero-engine |

National origin | United States |

Manufacturer | Teledyne Continental Motors |

First run | 1962 |

Major applications | Cirrus SR20 Cessna 172 Ilyushin Il-103 Cessna Skymaster Piper PA-34 Seneca Cessna O-2 Skymaster Cessna T-41 Mescalero |

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]
