Abstract
Description
本発明は、ディーゼル燃料に添加されるディーゼル燃料添加剤組成物、及びそれを用いた洗浄方法に関する。 The present invention relates to a diesel fuel additive composition added to diesel fuel, and a cleaning method using the same.
近年、環境問題への対応の観点から、ディーゼルエンジンの排気ガスに含まれる窒素酸化物（ＮＯｘ）や、粒子状物質（ＰＭ）等の低減が課題となっており、この課題を解決する手段として、コモンレール式の燃料噴射システムを備えたディーゼルエンジンがある。 In recent years, reduction of nitrogen oxides (NOx), particulate matter (PM), etc. contained in exhaust gas of diesel engines has become a problem from the viewpoint of dealing with environmental problems, and as a means to solve this problem There is a diesel engine equipped with a common rail fuel injection system.
コモンレール式の燃料噴射システムは、燃料を燃料噴射ポンプで加圧して、蓄圧室であるコモンレールに蓄圧し、このコモンレールに蓄圧された高圧燃料を燃料噴射ノズルよりシリンダー内に吹き込むものである。
コモンレール式の燃料噴射システムの燃料は高温、高圧に曝されることで、燃料中の様々な添加物が変性するようになり、特にインジェクターノズルに付着物が付着するという問題がある。
The common rail type fuel injection system pressurizes fuel with a fuel injection pump, accumulates pressure in a common rail that is a pressure accumulation chamber, and blows high pressure fuel accumulated in the common rail into a cylinder from a fuel injection nozzle.
