| Research Abstract |
Improvement of diesel combustion by ethanol intake port injection for the promotion of premixing of the in-cylinder injected diesel fuel, and by increased EGR for the reduction of combustion temperature. The smoke emission was reduced with promotion of premixing due to longer ignition delay and shorter injection period of diesel fuel with ethanol port injection, and the NOx was reduced with decreases in intake oxygen content by EGR regardless of ethanol quantity. When ethanol quantity was set to 20% of the total energy supply and intake oxygen was reduced to 15% with EGR, smokeless and low NOx operation was established over a wide load range.
