RESEARCH ON THE INFLUENCE OF ONION OIL AS ADDITIVE ON THE OPERATION OF DIESEL ENGINE POWERED BY BIODIESEL

The conventional fuel used to produce electrical energy and the burning of the conventional fuel causes global warming. Also, there is a depletion of these fuel and hence there is a need of alternative fuels. The biodiesel is a renewable fuel and it is a sustainable fuel. The biodiesel can be derived from waste cooking oil (WCO) as it increases the commercial value of the WCO. The biodiesel has lower oxidation stability and hence onion oil which has good anti oxidation value was added with WCO biodiesel. The engine tests were carried with WCO biodiesel added with onion oil shows that the addition of onion oil improves the thermal efficiency and improvement in cylinder pressure and heat release rate. We conclude that the onion oil can be used as additive to the WCO biodiesel.
