The Advanced Diesel Common Rail System for Achieving a Good Balance Between Ecology and Economy 2008-28-0017

At present, various efforts are being made in the industrial world to preserve the earth's environment. Automobile industry has to comply with the emission control regulations including NOx and PM and the requirement of reducing CO2 emission from the viewpoint of global warming protection and energy saving. In these situations, diesel engines having a high potential to reduce CO2 emission are attracting much attention. In order to enhance the potential of diesel to reduce CO2 while solving its problems (“slow, dirty, noisy”), common rail systems are vital. DENSO developed an advanced common rail system (CRS) that integrates fuel injectors capable of delivering up to five injection events per combustion cycle at 180MPa injection pressure. This paper describes the injection performance and effects of the 180MPa common rail system and then explains the next generation common rail system.
