Effects of novel microemulsion fuel additive Ce–Ru–O catalysts on diesel engine emissions

ABSTRACT

This paper investigated the role of microemission characteristics of a diesel engine when CeRuO₂ blended with diesel is used as a fuel. The major problem areas for combustion ignition (CI) engines are emissions. A novel microemulsion-based protocol was utilized to disperse the catalysts in the diesel fuel. The fuel was prepared comprising CeO₂, Ce_0.95Ru_0.05O₂, Ce_0.9Ru_0.1O₂, and Ce_0.8Ru_0.2O₂ by volume (0, 5, 10, and 20 mole%) was used in a CI engine. The catalyst microemulsion system remains stable upon its addition to the diesel fuel. The results show that the CI engine works well and the power outputs are steady running with the biodiesel blends at different loads. The acquired information were studied and found a decrease in HC, CO, NO_x, and soot.
