EXPERIMENTAL INVESTIGATION ON THE EFFECTS OF RAW MATERIALS DEGRADATION ON PERFORMANCE, COMBUSTION AND EMISSIONS OF A SINGLE CYLINDER ENGINE RUNNING ON BIODIESEL FROM WASTE LIPIDS

Abstract : In this paper, a single cylinder air cooled for strokes direct injection diesel engine was used to compare biodiesel from fat trap grease (AFRBD) with biodiesel from waste cooking oil (WCOBD) and with diesel fuel. The main difference between both biodiesel samples resides in the presence of short chain and branched methyl esters on AFRBD, and in its lower non saturated fatty acids content. Comparison was based on engine performance, combustion parameters and emissions. AFRBD resulted on a slight drop of brake power at 1500 rpm but it increased engine efficiency at full load. Biodiesel reduced polluting emissions of the engine as compared to diesel fuel. WCOBD recorded higher reduction of unburned hydrocarbon, carbon monoxide and particulate matter emissions but it increased the nitric oxides emissions. AFRBD has the advantage of reducing all pollutant emissions, including nitric oxides.
