OM355 Diesel Engine Emission Estandards Upgrading Use of Biodiesel from Waste Chicken Fat

Abstract:   (356 Views)

Vegetable oils or animal fats are the main sources for biodiesel fuel production. In this study, biodiesel (ethyl ester) was produced from chicken fat feedstock. The thermo-physical properties were measured according to ASTM standard. Biodiesel fuel blends (5, 10, 15 and 20) with different percentages of diesel were used. Experimental tests according to standard ECR-49 on the OM355 EU2 diesel engine were performed. The results showed that the properties of biodiesel from] chicken fat is in accordance with ASTM standard. The heating value of biodiesel lower than diesel fuel, but the density, cetane number, cloud point and flash point is higher than diesel fuel. The Chicken Fat Methyl Ester contains Oleaic (C18=1), Linoleaic (C18=2), Stearic (C16=0), Palmitaic (C18=0), Linolenic (C18=3) respectively 38.6, 33.8, 19.3, 6.1 and 2.2 percent. The brake specific fuel consumption (at all engine loads) increased at 1500 rpm engine speeds, but reduced at 2000rpm. Use of biodiesel in the OM355 EU2 diesel engine is generally found to reduce emissions of HC, CO and PM.  So, the use of B20 is upgrading UHC emission standard engines from EU2 to EU3. Also, the use of biodiesel to increase emission of NOX as compared to conventional diesel fuel but the use of B5 is reducing NOX.
