Now a days due to development in all areas and increase in demand of fossil fuels from automobile sector, it is necessary to find another sources of energy. Fossil fuel is the main source of energy. Biodiesel prepared from waste cooking oil is the best replacement for the fossil fuels. In this study biodiesel was prepared from waste cooking oil by trans-esterification process. This biodiesel mixes with conventional diesel in volume percentages 6, 12, 18, 24, 30, 36 as B06, B12, B18, B24, B30, B36 along with constant 5% EHN as an additive. Prepared biodiesel blends were tested in single cylinder four stroke diesel engine at constant engine speed of 1500 rpm and compression ratio maintained at 16:1. The results of experiments shows increase in brake power and brake thermal efficiency with load for all the blends. The brake specific fuel consumption decreases with increase in load. CO, HC emissions for waste cooking oil biodiesel blends were lower than diesel oil. NOx emissions for biodiesel blends were higher than diesel fuel.
