Diesel injection equipment is required to be more accurate and higher in pressure to meet the increasingly strict emission, fuel consumption regulations and higher engine performance. It also needs to achieve a number of requirements such as robustness against diversified market fuels, easy installation to engine, etc. DENSO has been working to develop 4th Generation Common Rail System (G4CRS) according to the following four concepts which are seemingly conflicting, since several years. This paper reports the G4CRS concepts, structure and performance combining high pressure up to 250 MPa as well as excellent fuel robustness and reliability. NOx and PM emission were reduced drastically and Fuel consumption was improved.
