Experimental Investigation of the Effect of Acetone Additive to Diesel Fuel on Engine Performance and Exhaust Emissions at Partial Loads

Abstract

In this study, it is aimed to gain good characteristics that can directly affect daily life with more environmentally friendly, economical, and performance fuels. For these purposes, acetone has been added to the fuel. Since acetone has a high vapor pressure, it is aimed to increase engine performance by taking advantage of its volatility. It is thought that emissions will also improve with increased engine performance. The experiments were carried out using a heavy-duty engine with a displacement of 11670 cc. Engine performance and emission values were investigated at 100, 200, and 300 Nm partial loads and at 600 rpm constant engine speed by adding 5% and 10% acetone to diesel fuel. The results were compared with pure diesel fuel. Compared to the pure diesel fuel, the BTE value of A5D95 fuel was observed to be 3.28% and 2.60% better, respectively, under 100 and 200 Nm load, while the BTE value of A10D90 fuel was 0.23% and 0.05% worse. Compared to the pure diesel fuel, the BTE value of A5D95 fuel was observed to be 3.28% and 2.60% better, respectively, under 100 and 200 Nm load, while the BTE value of A10D90 fuel was 0.23% and 0.05% worse. Since there was an unexpected decrease in the BTE value of pure diesel under 300 Nm load, only A5D95 and A10D90 fuels were compared at this load. It was found that the BTE value of A5D95 fuel under 300 Nm load was 0.65% higher than A10D90 fuel. While 10% acetone additive A10D90 fuel could not have a positive effect on efficiency, it was determined that A5D95 fuel with 5% acetone additive was more efficient than other fuel types at all loads. When the emission rates of D100, A5D95, and A10D90 fuels are evaluated according to the power they produce under 100, 200, and 300 Nm loads, the CO emission rate of A5D95 fuel is less than that of pure diesel at other loads except 100 Nm load. However, the NOx ratio was higher at all loads. These results support the higher efficiency of A5D95 fuel compared to pure diesel. Other results are discussed in detail in section 3.
