Abstract

In diesel-fueled internal combustion engines (ICEs), a preferred method is to add small amounts of additives to the fuel to reduce the negative impact of harmful exhaust emissions without compromising engine performance. The main reasons for preferring this method are the laws and regulations that are made mandatory and its easy applicability. For example, as the sulphur content of diesel fuels has been drastically reduced by legal regulations, the use of lubricity enhancing in diesel fuel additives has become a necessity. In this study, an experimental study was carried out to increase the performance of the diesel engine and reduce the harmful emission values by adding 10% fusel oil, which is ethanol production residue, to biodiesel produced from domestic waste oils. In order to obtain the desired benefits, different amounts of cetane enhancer n-octadecane and lubricity enhancer diethylenamine were added to the fuel mixture. The effects of n-octadecane and diethyleneamine additives added in equal amounts (500, 1000, 1500 and 2000 ppm) to biodiesel fuel and fusel alcohol mixture (B90F10) on engine performance and emissions were investigated. Engine performance and emission values of these fuel blends were measured between 1400 to 2600 rpm at full load. It was experimentally determined that fusel alcohol can be used as a fuel blend, that the residual material can gain economic value, and a total of 2000 ppm n-octadecane and diethylenamine additive can be added to a mixture of B90F10 by volume at optimum values to reduce harmful exhaust emissions.
