The Combustion and Exhaust Gas Emission of a Direct Injection Compression Ignition Engine Using Physic Nut Oil (Jatropha Curcas L.oil) 2007-01-3622

Due to the depletion of world petroleum resource and the increasing of exhaust gas emission, further efforts on the research to seek for new energy and reduce the exhaust gas emission have been made to fulfill the huge energy demands today. From this aspect, Biofuel has been found as one of the most promising fuel for its energy contribution and polluted exhaust gas emission reduction.
From various feedstock, Jatropha Curcas oil (JO) is motivated to use in diesel engine because of its several advantages such as non-edible oil, available in tropical areas, biodegradable and low cost compared to other biofuels. From the long-term durability test, using JO10 still has some problems caused by the high phosphor content in the fuel [1]. This presence causes much effect on injector coking and finally, piston and liner erosion, ring sticking. Further improvement is needed to remove the phosphor from the fuel (Degummed fuel). In this experiment, the Degummed Jatropha Curcas Oil (DJO) is tested and the results will be compared to JO for its performance, exhaust gas emission and combustion characteristics.
