The Continental C90 and O-200 are a family of air-cooled, horizontally opposed, four-cylinder, direct-drive aircraft engines of 201 in³ (3.29 L) displacement, producing between 90 and 100 horsepower (67 and 75 kW).〔''Type certificate data sheet no. E-252.'' Revision 29. (Sep. 15, 1982.) Department of Transportation. Federal Aviation Administration.〕 Built by Continental Motors these engines are used in many light aircraft designs of the United States, including the early Piper PA-18 Super Cub,〔''Aircraft specification no. 1A2.'' Revision 37. (Sep. 4, 1996.) Department of Transportation. Federal Aviation Administration.〕 the Champion 7EC,〔''Aircraft specification no. A-759.'' Revision 67. (Jun. 3, 2005.) Department of Transportation. Federal Aviation Administration.〕 the Alon Aircoupe,〔''Type certificate date sheet no. A-787.'' Revision 33. (Jul. 14, 2005.) Department of Transportation. Federal Aviation Administration.〕 and the Cessna 150.〔''Type certificate data sheet no. 3A19.'' Revision 44. (Mar. 31, 2003) Department of Transportation. Federal Aviation Administration.〕 Though the C90 was superseded by the O-200, and many of the designs utilizing the O-200 had gone out of production by 1980, with the 2004 publication of the United States Federal Aviation Administration light-sport aircraft regulations〔''Federal Register.'' Vol. 69, No. 143 (Jul. 27, 2004), pp. 44772-44882. Federal Aviation Administration, 14 CFR Parts 1, 21, et al., "Certification of aircraft and airmen for the operation of light-sport aircraft;" Final rule.〕 came a resurgence in demand for the O-200. The light-sport aircraft standard is for small, simple single- and two-seat aircraft for which the O-200 is well-suited. ==Design and development== The C90 was introduced in 1947 as a follow-on to the A65, which had been in production since 1939.〔(【引用サイトリンク】 title=Motors )〕〔(【引用サイトリンク】 title=Company Background )〕 Many of the designs powered by the C90 are upgraded variants of earlier A65 powered designs, such as the Piper J-3 Cub and PA-11 Cub Special,〔''Aircraft specification no. A-691.'' Revision 32. (Oct. 1, 1997.) Department of Transportation. Federal Aviation Administration.〕 Aeronca 7AC,〔 and Luscombe 8A.〔''Aircraft specification no. A-694.'' Revision 23. (Jul. 8, 1993.) Department of Transportation. Federal Aviation Administration.〕 The engine was developed from the earlier O-190 by increasing the stroke inch. This engine family is considered to be dependable, according to both industry publications and the FAA.〔''Special airworthiness information bulletin no. NE-03-45.'' (Jun. 27, 2003.) Department of Transportation. Federal Aviation Administration. Aircraft Certification Service.''〕 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."〔''Type certificate data sheet no. E3IN.'' Revision 3. (Jan. 16, 1968) Department of Transportation. Federal Aviation Administration.〕 The Rolls-Royce O-200-A powers the Beagle B.121 Pup 100,〔''Type certificate data sheet no. A22EU.''

Federal Aviation Administration.〕 the Bölkow BO 208 C Junior,〔''List 4: Propeller-driven aeroplanes not exceeding 8618 kg MTOM (including self-launching powered sailplanes.''

Germany.〕 the Avions Robin DR 220,〔 the Morane-Saulnier MS-880,〔 plus the Victa Airtourer 100.〔 All versions of the C90 and O-200 are four-stroke reciprocating engines and are all 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 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.〔 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. The standard certification for the C90 and O-200 specifies Avgas 80/87 as the minimum fuel grade.〔 Both are eligible for operation on automobile gasoline on the basis of Supplemental Type Certificates.〔(【引用サイトリンク】 title=STC number SE2031CE )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Continental O-200」の詳細全文を読む スポンサード リンク
