1 A Successful Approach to Reduce Emissions Using a Group Holes Nozzle Yoshiaki NISHIJIMA Makoto MASHIDA Satoru SASAKI Kenji OSHIMA The Common Rail System, (CRS), has revolutionized diesel engines. DENSO has been working on CRS technologies since they were first developed. This report describes the technology to simultaneously reduce NOx and PM through an innovative Group Holes Nozzle concept. We can obtain a more homogeneous, lean air-fuel mixture through Group Holes Nozzles, and by the addition of a cooled EGR, achieve pre-mixed combustion. This has underscored the potential in clearing future emission standards. Key words : Diesel engine, Fuel injection, Nozzle, Spray, Common Rail System, Pre-mixed combustion PM (g/km) Diesel technologies st step Pre-mixed combustion - Common rail technologies - EGR cooler, Intercooler (Reducing compression ratio) nd step Catalyzed DPF.4... nd step Future regulation EURO4 BASE st step...
