Abstract:The most important environmental problem of the society and recent studies is the pollution and emission of harmful gasses like unburnt hydrocarbons, soot formation and nitrous oxide from the CI engines, which necessitates to search on alternative fuel with additives for IC engine. Perovskites showed great interest in several applications and useful properties in various fields. It can be utilized as catalytically active catalyst for several reactions like carbon monoxide and hydrocarbons oxidation, hydrogen evolution reaction and nitrogen oxides, and oxygen reduction reactions. In present research paper, experimentation is carried out to study the effect of perovskite ceramic nanomaterial as an fuel additive with biodiesel an alternative fuel for diesel. Optimization technic was made by using Taguchi Design of experimentation. Suitable orthogonal array L25 was selected for a design of experiment. Keywords: Perovskite nanomaterial, palm biodiesel, castor biodiesel, Taguchi, etc.

INTRODUCTIONAlthough diesel engines are generally more efficient than spark ignition engines, emissions from the diesel engine are typically higher. This has resulted in a somewhat negative impact on its wide acceptance and use, especially in automotive applications. Recently, stringent emission legislation has been imposed worldwide on the oxides of nitrogen (NOx), and smoke and particulate matter emitted from automotive diesel engines. The different fuel properties such as the volatility, density, and the sulfur content in the fuel can be altered by the use of fuel additives. The fuel injection and mixture preparation processes are strongly influenced by properties such as the density, volatility, and viscosity, which are often interdependent. A number of experimental investigations have been reported with a wide variety of metal additives to improvethe fuel properties and the engine performance, as well asto reduce emissions. The effect of calcium, barium, iron, and nickel naphthenates have been studied, concluding that calcium and barium most efficiently reduce soot, by both suppressing soot formation and enhancing soot oxidationDiesel emissions from mobile sources have raised health and welfare concerns, but a number of technologies exist that can greatly reduce emissions from diesel-powered vehicles. One of the methods to vary the physicochemical properties and combustion characteristics of a hydrocarbon fuel is the use of additives, which are found to be especially effective in nanoparticle form, due to the enhancement of the surface area to volume ratio.Oxygenated fuel is nothing more than fuel that has a chemical compound containing oxygen. It helps fuel to burn more efficiently and reduce some types of atmospheric pollution. It can also reduce deadly carbon monoxide emissions and smog formation. Oxygenated fuel allows the fuel in vehicles to burn more completely.
