Transcripción del resumen del autor. Dieselhols (blends of diesels, biodiesels, and alcohols) have received considerable attention because of their low emission of CO2. In this study, new blended fuels were formed by adding 1-3 wt % of water-containing acetone (WA) or dehydrated acetone (AC) into a regular diesel (95-97%) and using 1 wt % of isopropyl alcohol (P) and 1 wt % of neat soybean oil (S) or soybean biodiesel (B) as stabilizers. The blended fuels were tested for their energy efficiencies and pollutant emissions in a diesel-fueled engine generator. Experimental results showed that the fuel blend WA3P1S1, which is composed of 3 wt % WA, 1 wt % P, and 1 wt % neat soybean oil, had a good fuel stability and 1.4-5.5% reduction of brake-specific fuel consumption (BSFC, mL kW-1 h-1). The better engine performance of WA3P1S1 was due to its higher fuel oxygen content, more complete combustion, and lower reaction temperature based on the water-cooling effect, which reduced emissions to 6.7-13.6% NOx, 9.6-33.3% particulate matter (PM), 7.7-14.3 total polycyclic aromatic hydrocarbons (PAHs), and 7.5-11.4% total BaPeq. Nevertheless, using recycled solvents for WA3P1S1, the CO2 emission was 4.92% lower than a regular diesel. Consequently, WA3P1S1 is a more sustainable fuel that can both save energy and reduce pollution.
