abstract

Because of its excellent catalytic activity and its ability to act as oxygen buffer causing simultaneous oxidation of hydrocarbons as well as the reduction of Nitrogen Oxide, Cerium Oxide (CeO2 ) is very special as a fuel additive for internal combustion engines. The present work investigates, through a series of experiments, the influence of the addition of CeO2 in the nanoparticle form on various physicochemical properties of Diesel oil, such as the cloud and pour points, the flash and fire points, the viscosity and the volatility which influence not only the spray characteristic but also the fuel atomization. Diesel oil samples, containing various percentage dosing levels of CeO2 nanoparticles of size range 20-30 nanometers are prepared using standard procedures of ultrasonic mixing, and used in the experiments. The physicochemical properties of the base fuel and the modified fuel are measured accurately using ASTM standard test methods. The effects on the individual fuel properties and the overall performance on a Diesel engine are studied, leading to inferences on the optimum dosing level.
