Experimental on eucalyptus oil with additives blend as a fuel for diesel engine

Abstract

Oils extracted from vegetables exist as future fuel full or partial alternate diesel fuels. Experiments have been done on using ethanol and diethyl ether as additives of eucalyptus ester to find out the impact of the fuel on the release of toxic gas, and engine effectiveness of using fuel directly in the engine without altering. Varied proportions of eucalyptus composition have been used as fuel. The proportion of the fuel in B20 has 20% of eucalyptus ester fuel and 80% of diesel,. The second 90% of B20 and 10% mass of ethanol is B20+E10 whereas B20+D10 has 90% of B20 and 10% mass of diethyl ether. Experiments has been carried out using varied composition of eucalyptus oil to find the impact on the engine feature such as engine power, brake specific fuel consumption, brake thermal efficiency, exhaust gas temperature, has been determined with the help of performance tests. The impact on the smoke opacity has also been done to find out the release of toxic gas such as CO, CO2, HC and NO. The outcome of such tests show that using B20 fuel lessens release 10% of diethyl specifically release of NO lessens by 51% in contrast to diesel. Mixture of B20+D10 offers enhanced engine effectiveness and lesser release of toxic gas in contrast to B20+E10 and B20 blends.
