Design and developmentEdit
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.
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. Rolls-Royce acquired the rights to the O-240, but not the IO-240 in 1977.
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. 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.
