“…Entropy production is affected by all irreversibilities, especially friction and temperature. As a result of Sanli et al [33] analyses, the entropy production of all fuels was the lowest during this period because the maximum torque occurred at 1800 rpm. The entropy generation for the fuels in the study was found to be 0.16-0.25 kW/K.…”

“…The addition of waste oil with a high thermal value allowed combustion become more efficient, reducing exhaust exergy. Sanli et al [33] have stated that the exergy decimation rate of fuels at 1800 rpm is between 45-50 kW, and it rises above this value at high engine speeds. The exergy destruction was calculated using fuel exergy, engine power and exergy of all losses.…”

We use fuel oil as an alternative fuel in compression ignition engines without modification. In this study, we performed tests at different engine speeds using diesel fuel oil fuel blends in a compression ignition engine. Energy and exergy analysis was carried out using the performance and emission values got from these tests. Through energy analysis, the energy distribution of the engine was determined and the thermal efficiency was calculated. The highest thermal efficiency is 34.76% on F40 fuel at 2250 rpm. In the exergy analysis, fuel exergy, exhaust exergy, entropy production, and exergy efficiency were calculated. The highest exergy destruction is 17.36 kW at 3250 rpm on D100 fuel. The exergy efficiency increases with engine speed. The highest exergy efficiency is 28.2% on F40 fuel at 2250 rpm.

“…For actual states, the output work done by the system is lower than maximum reversible work due to the irreversibility of the system. Therefore, the exergy efficiency can be defined as follows (Şanli and Uludamar 2019):…”

This research investigates the effects of the addition of Fe2O3 and Al2O3 nanoparticles (30, 60, and 90 ppm) and Fe2O3-Al2O3 hybrid nanoparticles to pure diesel fuel on the combustion, performance and emission characteristics of a diesel engine. The results indicated that fuel blends improved the combustion (in-cylinder pressure and heat release rate), performance (power, fuel consumption, and thermal and exergy efficiency), and emission characteristics of the engine. The results showed that the peak combustion pressure increased by 4% and the heat release rate was improved by 15% in comparison with pure diesel with the addition of the nanoparticles. Moreover, the rate of pressure rise increased by 18% compared to pure diesel with nanoparticle additives. Based on the results, the effects of Fe2O3 fuel blends on brake power, BTE, and CO emission were more than Al2O3 fuel blends, such that it increased power and thermal efficiency by 7.40 and 14%, respectively, and reduced CO emissions by 21.2%; moreover, the blends with Al2O3 nanoparticle additives in comparison with Fe2O3 nanoparticle blends showed a better performance in reducing BSFC (9%), NOx (23.9%), and SO2 (23.4%) emissions. Overall, the Fe2O3-Al2O3 hybrid fuel blend is the best alternative if the performance and emission characteristics of the engine are both considered.

“…The researchers argued that this could be due to the many variables that affect the irreversibilities. Moreover,Şanli and Uludamar [73] have reported that only a slight difference was observed among the destruction exergy rate of the different biodiesels with respect to diesel fuel and also concluded that the fuel type was not effective on the irreversibilities fraction. The comparison between the energy and exergy efficiency (i.e., energy and exergy outlet work) shown in Figure 8a-e demonstrates that both efficiencies had similar findings, approximately 26%, and 24%, respectively, with a small variation between them.…”

This research investigates the effects of a synthetic diesel-like fuel (Fischer-Tropsch diesel) and biofuels (ethanol and biodiesel) fuel blends on the energy-exergy efficiencies and gaseous exhaust emissions characteristics of a compression ignition engine. Two blends of alternative fuels denoted as E15B35FTD50 (15% ethanol, 35% biodiesel, and 50% Fischer-Tropsch diesel) and E15B35D50 (15% ethanol, 35% biodiesel, and 50% diesel) were experimentally studied on a single-cylinder diesel engine and compared to diesel fuel. The results show that the energetic and the exergetic efficiencies of the alternative fuels are comparable to those of the engine fueled with diesel fuel. The unburnt HC, NO, N2O, and NH3 emissions were reduced for the two alternative fuel blends compared to diesel, while CO emissions increased. The light HC species were found to slightly increase for the alternative fuel blends in comparison with diesel fuel. However, the total HC was considerably reduced by the combustion of E15B35FTD50 not only when compared to the diesel fuel combustion, but also when compared to E15B35D50. Overall, these results may contribute to identifying advantages and limitations in terms of energetic-exergetic analysis and emissions for the new generation of conventional diesel and hybrid electric vehicles that aim to achieve future emissions regulations.
