Internal combustion engines are established as the main power source for automobile vehicles. At presentemission norms become strict for any IC engine. The main emissions are CO, HC, NOX, PM and sooth. These emissions areformed due to incomplete combustion of fuel and high temperature available in the combustion chamber. Many techniquesare used to reduce this emissions such as changing the combustion chamber geometries, EGR, changing the pressure ofintake air and using catalytic convertors. The present work discuss about the effect of toroidal shape combustion chambergeometry for four stroke single cylinder DI diesel engine fueled with blends of an olive oil. The idea behind this geometry isto provide a powerful squish along with air movement within the toroidal chamber. Due to powerful squish the mask neededon inlet valve is small and there is better utilization of oxygen. It is proposed to carry out an experiment on a four strokesingle cylinder diesel engine by using olive oil as an alternate fuel at different proportions. Performance parameters such asBrake power, Brake specific fuel consumption and Brake thermal efficiency are calculated based on experimental study onthe single cylinder four stroke CI engine and emissions such as CO, CO2, UHC and NOX are measured. Performanceparameters and emissions characteristics of normal piston are compared with modified piston and other blends of olive oil. Ithas been observed that Performance parameters such as Brake Thermal efficiency is increased for modified piston withalternative fuel at B20 compared to Diesel fuel and Brake Specific Fuel Consumption is good for alternative fuel at B20compared to Diesel fuel. Emissions such as CO is slightly decreased for alternative fuel at B30 compared to Diesel fuel andNOX is slightly increased for modified piston with alternative fuel at B30 compared to Diesel fuel.
