The Novi engine is an American dual overhead cam supercharged V8 engine used in the Indianapolis 500. It was designed by Bud Winfield and Leo Goossen and built by Fred Offenhauser. ==Early years== The Novi was first used in 1941 under the "Winfield" name and produced over , an amazing output for the time.〔http://www.studebaker-info.org/Indy/NOvi/novi1.html〕 It was fitted to a 1935 frame built for a Miller engine, but it was very difficult to handle.〔Andy Granatelli recounts the difficulties and fatalities involved with the Novi in Karl Ludvigsen's, Novi V-8: Indy Cars 1941 through 1965.〕 After World War II, the Novi returned in 1946 with 510 horsepower (fitted in a more advanced Kurtis Kraft front-wheel-drive chassis) and performed beautifully, setting the track record and leading 44 laps in a car driven by Ralph Hepburn. Drivers such as Paul Russo and Duke Nalon later drove cars powered by the engine at notable speeds, but were unable to win. In 1949, Nalon's Novi was involved in a spectacular crash, where he hit the wall in turn three, rupturing the gasoline tank and creating a napalm-like 'wall of fire' most of the way through the turn. The engine's crowd-pleasing 'shriek' was caused by its gear-driven centrifugal supercharger which turned at five (5.35) times the crankshaft speed, thus giving it a banshee-like scream at full power.〔Offenhauser By Gordon Eliot White〕 The engine's four-camshaft and oversized valve design also gave it an exhaust noise much louder than other engines of its period, resulting in a deep-bass roar that sounded like a fighter plane. Some claimed that the noise actually rattled their teeth. The whole Novi package became legendary and had a notorious reputation for being dangerously powerful, particularly after racing veterans Hepburn (in 1948) and Chet Miller (in 1953) both died in practice piloting the enormously powerfully engined vehicles. 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「Novi engine」の詳細全文を読む スポンサード リンク
