Abstract
Since the PCI combustion is limited by strong knock at high load condition, a conventional diesel combustion is normally used. However simultaneous reduction of NOx and SOOT emission is difficult in the conventional combustion because its characteristic of the mixture has broad band of equivalence ratio distribution. Therefore homogenize of a mixture is required even though a conventional combustion. Thus 300MPa capable, the ultra high pressure injection system was made as a proprietary device for improvement of turbulent mixing rate and engine testing was conducted by using this.
