Lycoming IO-360 family
Lycoming IO-360 is a family of four-cylinder, horizontally opposed, air-cooled aircraft piston engines with direct drive. Fuel injection meters fuel in proportion to induction airflow, with fuel vaporization at the intake ports. Lycoming's operator's manual distinguishes these injected engines from the carbureted O-360 series and covers differences among the individual IO-360 models. The family shares a basic opposed-cylinder layout while its suffix models have their own installation and equipment details.
