ABSTRACT Energy demand is the hot topic of all developing and developed countries. Every day Energy demand increases in a big rate. So it is necessary to find an eco-friendly alternative solution, biodiesel is a promising alternative solution for this problem. The main purpose of this paper is to test and compare the performance of diesel engine using pure Lemon grass oil and Ginger grass oil blended with blended with diesel and cerium oxide is used as a catalyst. Lemon grass oil and Ginger grass oils were esterified using the transestrification method. Then samples A10, A20, A30, C10, C20 and C30 were prepared using magnetic stir ration process. The measuring parameters are break power; break thermal efficiency, specific fuel conception, and volumetric efficiency. Result shows that C10 gives better performance than D100 and other biodiesel samples. Keyword: Biodiesel, Lemon grass oil, Ginger grass oil, cerium oxide, break thermal efficiency, specific fuel consumption.

INTRODUCTION
Diesel engines, are used in a variety of applications, such as, power generation, transportation ,agriculture ,offshore drilling, military marine ,telecommunication eneratorsets ,and elsewhere[1–These are the back bone of nation’s economy especially for the developing countries, like India. This attribute dtoit fundamental dvantagesinthe for mofhigh torque, turbo charging capability, high efficiency, and lower main- tenancy [1,3]. However, as the use of diesel engines increasing, the stock of diesel is diminishing vary rapidly, with a continuous increase in harmful pollution.Thes include oxides of nitrogen (NOX), oxides of carbon (COandCO2), oxidesofsulfur(SOX), hydrocarbon (HC) ,smoke,etc. [3].countries who import fossil fuels from other countries for their current energy requirements, economic growth and progress are very much worried about their fast depletion , it might create in the event of our not being able to find a suitable alternative fuel [4]. This has pushed the researchers all over the world to find a suitable alternative energy sources like, photovoltaic, hydrogen fuel and bio fuels and emerge themselves as energy independent nations [5].Among the available options, biodiesel looks to be the most promising solution to the fuel calamity [6].Usage of vegetable oil in a diesel engine is not a new concept. Rudolph Diesel, who invented diesel engine, himself, had tried peanut oil in his engine. Vegetable oil has both positive and negative influence on the engine. Cold flow properties, the viscosity and volatility of vegetable oils are noted as negative impacts on the diesel engine and may lead to engine reduced performance and chocking. [7].On the other hand, their rich oxygen content, biodegradability, renewability and emission reduction are their merits [8].Researchers Puhan et al. [9] observed that there is a increase in oxides of nitrogen emission as on increasing the injection pressure researchers Jaichandar and Annamalai [10] studied the influence of open combustion geometry with pongamia biodiesel and showed that Toroidal combustion chamber geometry caused thermal efficiency to increase due to better air and fuel mixing. Xue [11] reviewed the effect of biodiesel on engine emissions and performance, and concluded that, blends with a less than 50% of biodiesel are technically feasible as alternative fuels in a CI engine with no or minor changes to the engine. . Hansen [12] reviewed the ethanol-diesel fuel blend for engine performance, emissions and durability. Riberio [13] reviewed the role of additives for diesel and biodiesel blended (biodiesel or ethanol) fuels. Gürü [14] observed that the manganese additive had a stronger impact on the reduction of the fuel's freezing point, and also the exhaust emission of the fuel. Jung [15]. They observed that the addition of cerium to the diesel shows significant changes in number e weighted size distributions, kinetics of oxidation, and light off temperature.
