Effects of DGM and Oxidation Catalyst on Diesel Exhaust Emissions 1999-01-1137

The authors of this article reported in the previous paper[1] that the employment of oxidation catalyst was superior to the fuel modification such as reduction of T90 or poly-aromatic hydrocarbons in the improvement in exhaust emission reduction effect, as a part of approach to reduce diesel exhaust emissions based on fuel modification. In this paper, the exhaust emission reduction effect of a mixed diesel fuel containing 10% di-ethylene glycol di-methyl ether (DGM), which is an oxygenated fuel, in diesel fuel was evaluated, and the reduction effect was also evaluated with oxidation catalyst equiped engine. As the result, the THC, CO and PM reduction effect of DGM was clarified and further great PM reduction effect of the combination of DGM and oxidation catalyst was clarified.
