翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Low-speed pre-ignition ： ウィキペディア英語版 Low-speed pre-ignition Low-speed pre-ignition (LSPI), also known as stochastic pre-ignition (SPI),〔(【引用サイトリンク】url=http://papers.sae.org/2014-01-1226/= SAE International )〕 is a pre-ignition event that occurs in gasoline vehicle engines when there is a premature ignition of the main fuel charge.〔(【引用サイトリンク】url=http://www.autoblog.com/2010/10/15/aggressive-engine-downsizing-held-back-by-low-speed-preignition/=Auto Blog )〕 LSPI is most common in certain turbocharged direct-injection vehicles operating in low-speed and high-load driving conditions.〔(【引用サイトリンク】url=http://saeeng.saejournals.org/content/7/2/584.abstract=SAE International )〕 LSPI events are random and infrequent, and their effects on impacted vehicles can include very high-pressure spikes, loud knocking noises and sometimes catastrophic engine damage.〔(【引用サイトリンク】url=https://books.google.com/books?id=8xW85EAKkKwC&lpg=PP1&pg=PA397#v=onepage&q&f=false=Engine Testing: The Design, Building, Modification and Use of Powertrain Test Facilities )〕 ==Impact on engine design== Automakers use engine downsizing to help improve vehicles’ fuel efficiency and reduce emissions, and use turbocharger technology to recover power lost in the downsizing process.〔(【引用サイトリンク】url=http://www.autoblog.com/2010/10/15/aggressive-engine-downsizing-held-back-by-low-speed-preignition/=Auto Blog )〕 The presence of LSPI limits automakers’ ability to capture the full potential of turbocharged engines to meet increasing fuel-efficiency requirements 〔(【引用サイトリンク】url=http://papers.sae.org/2014-01-1226/=SAE International )〕 and to further reduce carbon-dioxide emissions.〔(【引用サイトリンク】url=http://www.greencarcongress.com/2010/10/p3-20101007.html= Green Car Congreess )〕 Updated oil-performance standards are taking shape to address LSPI. General Motors’ next-generation dexos1 specification, scheduled for release in 2015, will include an engine test based on a GM 2.0-liter four-cylinder Ecotec that will test for LSPI.〔(【引用サイトリンク】url= http://www.calact.org/assets/Mike%20Kershaw.ppt= Calact )〕 The proposed ILSAC GF-6 standard will also include a test for oil-related LSPI events in gasoline direct-injection engines based on a Ford 2.0 L four-cylinder Ecoboost engine.〔(【引用サイトリンク】url=http://www.stle.org/resources/articledetails.aspx?did=1671=STLE )〕 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「Low-speed pre-ignition」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.
