| Outline of Final Research Achievements |
We proposed to reduce simultaneously nitrogen oxide (NOx) and soot emission from diesel engines’ exhaust gas by using a fuel of light oil blended with liquid dimethyl ether (DME) or by adding DME or ozone (O3) to intake air. In the method of using light oil blended with DME, 15wt% of DME blending was most effective for simultaneous reduction of NOx and soot formation. In the method of adding DME to the intake air, up to 1.5 NL/min DME addition, soot was reduced with no NOx increase. In the method of adding O3 to the intake air, promotion of combustion of engine was confirmed by experiment and numerical simulation.
