Energy is the main source for economic growth of any nation. The fossil fuels are the main source of energy. Many of the researchers concluded that these sources are going to be depleted in near future because of rapid increase in consumption of these fuels. The cost of the fuel is also increasing day by day due to the increase in demand for petro diesel. In addition the more usage of petro diesel products increases the environmental pollution. Therefore there is a necessity to go for alternative fuel in place of petro diesel products. The properties of vegetable oils are nearer to diesel fuel but certain properties like low voltality, high viscosity creates some problems in CI engine. Hence in this work to reduce the effect biodiesel properties combustion chamber design is modified. The various combustion chamber geometries considered in this work are Toroidal, Shallow depth and Hemispherical. The performance parameters like indicated, brake thermal efficiencies, mechanical efficiency and specific fuel consumption are evaluated. The pollutants parameters like oxides of nitrogen, un burnt hydrocarbons, carbon monoxide and carbon dioxides are determined. From the investigation it is observed the brake thermal efficiency and mechanical efficiency are about 1.14% and 7.1% increased respectively. Further the oxides of nitrogen pollutants are decreased about 18.7%.
