In a cooperative venture, Rolls-Royce produced these same designs in England, under separate certification, with model designations beginning RR, e.g. the Rolls-Royce RR C90-12FH is the equivalent of the Continental C90-12FH; the Rolls-Royce versions are "directly interchangeable with the equivalent models manufactured by Continental."<ref name="TCDS E3IN">Type certificate data sheet no.

The C90 was introduced in 1947 as a follow-on to the A-65, which had been in production since 1939.<ref name="Aerofiles">Motors. Aerofiles: A Century of American Aviation.

[edit] Record applications
An engine designated the IOL-200, an O-200 variant modified with fuel injection and liquid cooling, powered the 1986 non-stop, non-refueled global circumnavigation flight of the Scaled Composites Voyager. The 110-horsepower (82 kW) IOL-200, also referred to as the Voyager 200, was the rear engine and—unlike the forward engine, another modified engine, a Continental-built O-240—ran throughout the entire 9-day flight save for a four-minute shutdown due to a fuel problem.<ref name="NASM Voyager">Rutan Voyager.

Formula One racer Nemesis, the Sharp DR 90 designed and and flown by Jon Sharp, was powered by a stock O-200. Between 1991 and 1999, the plane won 45 of the 48 events in which it was entered, as well as winning three Louis Blèriot Medals, four Pulitzer Trophies, and setting 16 speed records in its class. In one of those records, Nemesis was clocked at over 290 mph (467 km/h).<ref name="NASM Nemesis">Sharp DR 90 "Nemesis". Smithsonian: National Air and Space Museum.

[edit] Design
Four-stroke reciprocating engines, all versions of the C90 and O-200 are similar in size, displacement, and weight. These engines are typically fitted with an updraft carburetor, though the C90-8FJ, -12FJ, and -14FJ are equipped with fuel injection systems. They utilize an a redundant ignition system requiring no external power, driving two magnetos, each of which fires one spark plug per cylinder. Each cylinder has one intake valve and one exhaust valve, pushrod-activated.<ref name="TCDS E-252"/>
Continental's recommended time between overhaul (TBO) for these engines is 1,800 hours of operation or 12 years in service, whichever is reached first.<ref name="SIL98-9A">Teledyne Continental Motors (2003-03-28). Service Information Letter SIL98-9A.</ref> The standard certification for the C90 and O-200 specifies the use of aviation gasoline of a minimum 80/87 grade;<ref name="TCDS E-252"/> both are eligible for operation on automobile gasoline on the basis of Supplemental Type Certificates.<ref name "SE2031CE">Department of Transportation.

[edit] C90
While the C90 is approved for takeoff power of 95 horsepower (71 kW) for 5 minutes, the designation derives from its continuous power rating of 90 hp (67 kW). As noted above, certain models of the C90 replace the usual carburetor with a fuel injection system. In addition, there are models which provide for the installation of a controllable pitch propeller and one, the C90-12FP, designed for pusher installation.<ref name="TCDS E-252"/>
[edit] O-200
The O-200 is an updated and upgraded version of the engine, achieving increased power of 100 hp (75 kW) as a result of higher maximum rpm. The standard and most common model of the engine is the O-200-A; the -B model is designed for pusher installation, and the -C model provides for the installation of a controllable pitch propeller.<ref name="TCDS E-252"/>
