A jacketed fuel injection pipe (also known as double walled, twin walled or sheathed fuel injection pipe) is a special type of fuel injection pipe fitted to diesel engines. The pipe incorporates an outer jacket that shrouds the inner high pressure pipe. This jacket is usually metallic in construction and can either be a thin walled tube or convoluted hose. In the event of a burst in the injection pipe the leaking fuel will be collected by the jacket and piped away safely to an alarm device to notify operators of a potential problem. Jacket fuel lines are found predominately in marine applications. Adoption in power generation is becoming more common. ==Legislation== In 1994 the International Maritime Organization required all ships subject to SOLAS to be fitted with jacketed fuel lines. Existing vessels and new builds constructed before 1998 were required to comply by 1 July 2003. Dispensation was given to engines smaller than 375 kW (500 hp) providing they were fitted in a suitable enclosure. In 2006 the IMO relaxed the regulation by applying it only to ships constructed on or after 1 February 1992, but without engine power limitation. 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「Jacketed fuel injection pipe」の詳細全文を読む スポンサード リンク
