Day by day vehicle population in the world is increasing and usage of fossil fuel is also increasing. By using fossil fuel as a fuel in I C Engines will cause for health hazards, Global pollution, at the same time sources of fossil fuels are also decreasing. The countries like INDIA are depending on other countries for the petroleum based fuel and it will affect the development of the country also. The usage of Diesel fuel in India is six times greater than the Gasoline (petrol) fuel. The India has lot of resources to produce Liquid alternate fuels like Ethanol, Methanol, and Bio-Diesel etc... Bio-Diesel is a one of the Alternate fuel for Diesel fuel and it is produced from renewable sources (Plants). The pongamia tree is normally grown in the banks of canals, rivers etc... If the ripen and fallen seeds are collected that is sufficient to produce the bio fuel for the Indian farmers requirements.  This paper presents a brief review about different research work done on the pongamia bio diesel. Plenty of researchers are doing their research on bio diesel by various innovative methods, fuel parameters like blending, pre – heating, dual fuel and engine parameters like compression ratio, fuel injection pressure, injection timing etc... In this paper various journals are collected from web resources and brief study has been done, concluded.
