Depletion of fossil fuels and continuous increment of petroleum prices have prompted the interest towards the use of inedible vegetable oils as alternate source of fuel for diesel engines. Increased viscosity and poor volatility is a major problem related to the use of straight vegetable oils (SVOs) which may cause a number of operational and durability problems. Preheating is a simple technique to lower the density and viscosity of vegetable oil before utilizing in an engine for getting better results. Exhaust gas can be used as the heat source for this purpose. In this paper, a comprehensive study has been conducted to review the performance and emission characteristics of a compression ignition engine fuelled with preheated Jatropha, Mahua and Rice Bran Oil. Diesel is taken as the baseline fuel for comparison of performance and emission characteristics for all the three cases [1]. A single cylinder, four stoke, constant speed, water cooled, direct injection diesel engine is used for the experiments. The acquired data were analyzed for various parameters such as thermal efficiency, brake specific fuel consumption (BSFC), smoke opacity, CO 2, CO and HC emissions.
