Abstract: Energy is the basic requirement for the existence of human being in today’s digital world. Diesel engines are widely used in light, medium and heavy-duty vehicles and power generation in heavy machinery, because of higher thermal efficiency and the ability for lean operation. Further, the lean burn capability helps to lower the carbon monoxide (CO) and Hydro carbon (HC) emissions compared to those of a spark ignition (SI) engine. The world energy stimulated the researchers to look for new sources of fuel, which must be renewable, locally available and environmentally benign. In this regard, the significance of biodiesel as technically and commercially viable alternative to fossil-diesel has led to intense research in the field. Biodiesel is made from different feedstock depending on the availability. This paper Extraction of non-edible forestry seed oil in the utilization as a Blend fuel. Milletia pinnata is a species of tree in the pea family, Fabaceae, that is native to southern Asia. It is often known by the synonym Pongamia pinnata as it was moved to the genus Millettia only recently. Common names include Indian Beech Tree, Honge Tree, Pongam Tree. The main advantage of biodiesel is that it potentially reduces the key pollutants, carbon monoxide, unburnt hydrocarbons and particulate matters. However, many further researches need to be carried out to understand the relationship between the type of biodiesel feedstock and performance and emission
