Continental O-240

The Continental O-240 engine is a four-cylinder, horizontally opposed, air-cooled aircraft engine that was developed in the late 1960s for use in light aircraft by Continental Motors, Inc. The first O-240 was certified on 7 July 1971.[1][2]

Design and development

The 130 hp (97 kW) O-240 was a new engine design derived from the six-cylinder Continental O-360 and introduced in 1971. It is generally similar in overall dimensions to the Continental O-200, but with a higher 8.5:1 compression ratio, designed to run on 100/130 avgas. The O-240 delivers 30% more power than the O-200 while it weighs only 12% more. It may be mounted in tractor or pusher configuration.[3][4]

The O-240 was produced under license in the United Kingdom by Rolls-Royce Limited and was used to power the Reims Aviation-built Cessna 150s constructed in France under license.[5] Rolls-Royce acquired the rights to the O-240, but not the IO-240 in 1977.[2]

The fuel-injected IO-240-A and -B were introduced in 1993. The A and B versions differ only in the type of fuel injector used.[1][4]

The IOF-240 is similar to the IO-240-B except that it employs an Aerosance FADEC system to control the ignition and fuel injection systems.[1] The engine was not selected to power any production North American-manufactured aircraft until the Liberty XL2 entered production in 2006 powered by the IOF-240-B.

Performance

gollark: Please indent stuff in the if blocks and put the then on the same line as the if.
gollark: That's worse.
gollark: In Rust infinite looping is done with just `loop`, which is cool.
gollark: Yes, but it's NICE TO NOT BE HORRIBLE.
gollark: Well, stuff in your ifs have four spaces, but your loop is two spaces deep.
