"Formulas" limiting engine capacity had been used in Grand Prix racing on a regular basis since after World War I. The engine formulae are divided according to era. ==Operation== Formula One currently uses 1.6 litre four-stroke turbocharged 90 degree V6 reciprocating engines. The power a Formula One engine produces is generated by operating at a very high rotational speed, up to 15,000 revolutions per minute (RPM).〔(Engine / gearbox ) Understanding the Sport, Official Formula 1 Website〕 This contrasts with road car engines of a similar size which typically operate at less than 6,000 rpm. The basic configuration of a naturally aspirated Formula One engine had not been greatly modified since the 1967 Cosworth DFV and the mean effective pressure had stayed at around 14 bar MEP.〔(F1 Engine Power Secrets ), Ian Bamsey, June 2000 RACER magazine〕 Until the mid-1980s Formula One engines were limited to around 12,000 rpm due to the traditional metal valve springs used to close the valves. The speed required to operate the engine valves at a higher RPM called for ever stiffer springs, which increased the power loss to drive the camshaft and the valves to the point where the loss nearly offset the power gain through the increase in rpm. They were replaced by pneumatic valve springs introduced by Renault, which inherently have a rising rate (progressive rate) that allowed them to have extremely high spring rate at larger valve strokes without much increasing the driving power requirements at smaller strokes, thus lowering the overall power loss. Since the 1990s, all Formula One engine manufacturers used pneumatic valve springs with the pressurised air allowing engines to reach speeds of over 20,000 rpm.〔〔https://www.youtube.com/watch?v=_HwHgEWnpfs〕〔https://www.youtube.com/watch?v=BPdm51QwZEw〕 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「Formula One engines」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
