The Lycoming O-540 is a family of air-cooled six-cylinder, horizontally opposed fixed-wing aircraft and helicopter engines of 541.5 cubic inches (8,874 cc) displacement, manufactured by Lycoming Engines. The engine is a six-cylinder version of the four-cylinder Lycoming O-360.
Design and development
[edit]Producing between 230 and 350 horsepower (170 and 260 kW)[1] these engines are installed in a large variety of aircraft.[2] The main competitors are the Continental IO-520 and IO-550 series.
An AEIO version was developed for high-performance competition aerobatics aircraft. Starting at 260 hp (190 kW) the power was eventually increased to 300 hp (220 kW). The AEIO-540 family has achieved considerable success in aircraft such as the Extra 300, CAP 232, and Zivko Edge 540.
Variants
[edit]All engines have an additional prefix preceding the 540 to indicate the specific configuration of the engine.[1] The numerous engine suffixes denote different accessories such as different manufacturers' carburetors, or different magnetos.
