翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク VarioRam ： ウィキペディア英語版 VarioRam VarioRam is a Porsche-patented engine induction system that was first introduced on the 1992 model year 964 Carrera RS motor sport special. It became standard on the 911-series starting from the M64/21 engine on the model year 1996. As the name suggests, VarioRam varies the effective length of the inlet ducting depending upon engine load and speed. A long intake length at low rpm provides a better pulse tune because the pulse won't travel back and forth as many times, which aids low-end torque because the high pressure pulse may otherwise contribute to reversion and thereby decreased volumetric efficiency. At higher engine rpm, the intake length is reduced. The result is a flatter torque curve, with more torque available at low- and mid-range engine speeds compared to a similar non-VarioRam engine. ==External links== * (VarioRAM Explained ) * (VarioRAM diagram ) 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「VarioRam」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.
