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-Cessna FRA150 Aerobat, a more powerful aerobatic model of the Cessna 150 constructed in France by Reims Aviation 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.

IO-240-A
Dual ignition, 125 hp (93 kW) at 2800 rpm, dry weight 246 lb (112 kg), uses a TCM 639231A27 fuel injector[1]
IO-240-B
Dual ignition, 125 hp (93 kW) at 2800 rpm, dry weight 246 lb (112 kg), uses a TCM 639231A34 fuel injector[1]
