An Effect of Biosolar-Water Emulsion on Small Marine Diesel Engine

This study aims to analyze the effect of water/biosolar emulsion fuel on the performance of engine diesel used in small capacity diesel engines. The fuel used is a mixture of biosolar 20% which is added 10% and 15% water (b20,WDE 10%, WDE 15%) which will be compared with dexlite fuel and biodiesel 20% (b20). Measurement of engine performance with various fuels was carried out in accordance with IMO marine engine regulation tier 3. The water-emulsified diesel could be used in the light-duty small diesel engine without modifications. The result shows that the net diesel fuel consumption and the exhaust gas temperature decreased with increasing water content of fuels over the investigated loading range.Performance produced by DWE 10% and 15% will been reduce Power, and Torque at each RPM. In detail, DWE 10% has better results than the DWE 15%. In the NOx emission test results, the use of water/biodiesel emulsified fuels 10% and 15% can reduce NOx emissions.
