, now part of AVIC International since 2010. 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.Taylor 1976, pp. 792–793 There was no carbureted version of this engine, which would have been designation ''O-360'', therefore the base model is the ''IO-360''.
