Internal combustion engines are established as the main power source for automobile vehicles. At present emission norms become strict for any IC engine. The main emissions are CO, HC, NOX, PM and soot. These emissions are formed due to incomplete combustion of fuel and high temperature available in the combustion chamber. Many techniques are used to reduce this emissions such as changing the combustion chamber geometries, EGR, changing the pressure of intake air and using catalytic convertors. The present work discuses about the effect of cylindrical shape combustion chamber with truncated cone piston bowl geometry for four stroke single cylinder DI diesel engine fueled with blends of an olive oil. The idea behind this geometry is to provide a truncated cone cavity on piston head with base angle of 300. In truncated cone cylindrical shape combustion chamber due to the desirable squish and swirl there is a better utilization of oxygen. It is proposed to carry out an experiment on a four stroke single cylinder diesel engine by using olive oil as an alternate fuel at different proportions. Performance parameters such as Brake power, Brake specific fuel consumption and Brake thermal efficiency are calculated based on experimental study on the single cylinder four stroke CI engine and emissions such as CO, CO2, UHC and NOX are measured. Performance parameters and emissions characteristics of normal piston are compared with modified piston and other blends of olive oil. It has been observed that Performance parameters such as Brake Thermal efficiency is increased for modified piston with alternative fuel at B20 compared to Diesel fuel and Brake Specific Fuel Consumption is good for alternative fuel at B20 compared to Diesel fuel. Emissions such as CO is slightly decreased for alternative fuel at B20 compared to Diesel fuel and NOX is slightly increased for modified piston with alternative fuel at B30 compared to Diesel fuel.
