“…NO x emission was increased by 2.12-8.32% compared to diesel. Tüccar et al [151] compared the emission characteristics between pure diesel and 20% of microalgae blend together with 80% of pure diesel. They claimed that the smoke emitted using the B20 blends fuel is reduced by 3.1% compared when using pure diesel.…”

“…Compared to methanol and ethanol, butanol is an appropriate renewable fuel that has a number of desirable properties for its application in diesel engines, because it is less hydrophilic, has a higher cetane number and heat value, a lower vapor pressure, and a much greater miscibility with diesel [7]. The previous studies have reported that butanol-diesel blends show the satisfied exhaust emissions and engine performance [8][9][10].…”

“…In the last few decades, alcohols have been used as additives and alternative fuels in the diesel engine (Agarwal, 2007;Campos-Fernández et al, 2012;Fraioli et al, 2014;Tüccar et al, 2014) to address the challenges of emissions of particulate matter (PM), total hydrocarbons (HC), nitrogen oxides (NO x ) carbon dioxide (CO 2 ), carbon monoxide (CO) as well as toxic chemicals such as polycyclic aromatic hydrocarbons (PAHs) (Doğan, 2011;Popovicheva et al, 2014;Tsai et al, 2014). These exhaust pollutant emissions pose huge risks to human health in form of cardiovascular disorders, respiratory diseases and lung cancer especially PAHs, which are carcinogenic as well as mutagenic .…”

In this study, two diesel blends with different iso-butanol and isopropyl alcohol ratios, 5% iso-propanol with 15% isobutanol and 1% iso-propanol and 19% iso-butanol, were used and compared against the performance of petroleum diesel as a base fuel. Additionally, water addition strategy was included for further comparison. Brake specific fuel consumption (BSFC) increased with increasing ratios of iso-butanol and water fractions, since the heating value decreased resulting in more fuel being combusted to maintain the same power output. On the other hand, brake thermal efficiency (BTE) increased with increasing water content. Specifically, P5B15W1 had a higher BTE than regular diesel at low engine loads (12 kW and 25 kW-LS). Compared to the regular diesel, the results show that in-cylinder pressures slightly increased while HRR had longer ignition delay with higher iso-butanol and water content. For the two different ratios of blended diesel, P1B19 registered NO x emission reductions factors by about 12-35% compared regular diesel due to its low heating value and combustion temperature, while those for P5B15 were reduced 8-33% in comparison to regular diesel. For CO and PM emission factors, P5B15 had better performance than P1B19 which showed 13-37% and 37-50% lower than regular diesel, respectively. However, HC emission factors were all greater than those of regular diesel with the highest increase being from P1B19. This diesel blend, P1B19 showed 6-30% and 3-10% higher HC emission factors than regular diesel and P5B15, respectively. For water containing blends, NO x emission factors decreased with an increase in water content. The trends for CO and PM emission factors were similar to those of non-water containing diesel blends. P5B15W1 had largest decrease which showed 5-17% and 7-26% lower CO and PM than regular diesel, respectively. Notably, the CO and PM emission factors are all higher than non-water contain blended diesel. As for HC, P5B15W1 had an increase of about 26-51%. Moreover, the total-PAHs emission factors between two different ratios of blended diesel were compared whereby P5B15 had 12-22% lower than P1B19. Besides, total-BaPeq emission factors are similar to totalPAHs emission, which P5B15 had largest reduction by 28-44%. In summary, P5B15 would be a best choice in terms of PM reduction, while the best choice for NOx control would be P1B19W0.5 blend. Ultimately, further economic feasibility studies are recommended for an overall performance evaluation.
