The present fossil fuel crisis and increasing vehicle population made us to think of alternate fuels. The abundance of the fossil fuels is expected to be exhaust in another 30-40 years. The cost of the fossil fuels is day by day increasing and also the emission from these fuels increases the air pollution. With keeping in view of all the above said points, it is made us to think of alternate fuels for all CI Engines. Among alternate fuels, the Pongamia oil blended with Methanol will promise for substituting the diesel. With pure vegetable oils there is combustion problems and which leads to more emissions in the exhaust. The present investigation evaluates Pongamia oil blended with Methanol in Diesel Engine. A Twin cylinder Diesel Engine adapted to study the Brake thermal efficiency, Brake specific energy consumption, and emissions in Low Cetane fuels. In this study, the diesel engine was tested using Diesel and Low Cetane Fuels. From this study the emissions like HC and CO has been reduced and Low Cetane Fuels are substitute to diesel fuel. To overcome the above problems we use combustion additives at the time of combustion. So here we use Pongamia oil blended with Methanol as alternative fuels in diesel Engine and perform various tests and evaluate its performance.
