The Common-Rail System, (CRS), has revolutionized diesel engines. DENSO has been working on CRS technologies since it produced. This report describes the technology to reduce NOx and PM simultaneously through an innovative Group Holes Nozzle concept. We can obtain a more homogeneous lean air-fuel mixture through the 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.
