Dual Fuel engines with Biodiesel & Oxygenated fuels-A Study

Biodiesel is receiving increased attention as an alternative, non-toxic, biodegradable and renewable diesel fuel. Biodiesel comes in use due to depletion of petroleum fuels and the environment benefits. Biogas can also be used with the biodiesel in I.C engine because of its better mixing ability and clean burning nature with very minor modifications in the engine. The usage of oxygenated fuels can reduce the particulate matter (PM) emissions from the engine without large modification of the engine. The present study has conducted to evaluate the properties of rice bran biodiesel and effect on the performance and emissions characteristics of C.I. engine using rice bran oil methyl ester with oxygenated fuel of Diethyl Ether blended with diesel as a pilot fuel and biogas as a gaseous fuel under dual fuel mode. This study is conducted in two phases. In the first phase, the blends of D80-B10-DEE10 and D60-B20-DEE20 with the use of biogas at a fixed flow rate of 0.9 kg/hr are performedat different load conditions and compared with diesel. In the second phase, the blends of D80-B10-DEE10 and D60-B20-DEE20 are performed at different load conditions.
