“…Increasing price, environmental pollution, and depletion of non-renewable fossil fuels have encouraged researchers to find renewable fuels. One alternative fuel that has been widely used in compression ignition (CI) engines is biodiesel [1][2][3][4]. Some researchers have analyzed the first law of thermodynamics (thermal balance) at different operating conditions, especially by using biodiesel fuel [5][6][7][8][9].…”

Contrary to energy, exergy may be destroyed due to irreversibility. Exergy analysis can be used to reveal the location, and amount of energy losses of engines. Despite the importance of the exergy analysis, there is a lack of information in this area, especially when the engine is fueled with biodiesel–diesel fuel blends under various injection operating parameters. Thus, in this research, the exergy analysis of a direct-injection diesel engine using biodiesel–diesel fuel blends was performed. The fuel blends (B0, B20, B40, and B100) were injected into cylinders at pressures of 200 and 215 bars. Moreover, the simulation of exergy and energy analyses was done by homemade code. The simulation model was verified by compression of experimental and simulation in-cylinder pressure data. The results showed there was good agreement between simulation data and experimental ones. Results indicated that the highest level of in-cylinder pressure at injection pressure of 215 bars is more than that of 200 bars. Moreover, by increasing the percentage of biodiesel, the heat transfer exergy, irreversibility, burnt fuel, and exergy indicator decreased, but the ratio of these exergy parameters (except for heat transfer exergy) to fuel exergy increased. These ratios increased from 46 to 50.54% for work transfer exergy, 16.57 to 17.97% for irreversibility, and decreased from 16 to 15.49% for heat transfer exergy. In addition, these ratios at 215 bars are higher than at 200 bars for all fuels. However, with increasing the injection pressure and biodiesel concentration in fuel blends, the exergy and energy efficiencies increased.

Summary Prolonged storage of biodiesel leads to deterioration of fuel properties and its usage in engines results in drop‐in performance characteristics. The present study deals with the effect of natural antioxidants on the storage stability of binary biodiesel blend of Jatropha biodiesel and lemongrass oil, which are synthesized through transesterification and steam distillation process, respectively. Natural antioxidants such as sesame, horse gram, sweet basil, coffee, and peas were employed in the current study. Thermal analysis of the antioxidants was carried out utilizing differential scanning calorimetry and thermogravimetric analysis to study the effect of temperature on antioxidants. Ethanol extract of natural antioxidants was prepared at various concentrations such as 500, 1000, and 1500 ppm. Total phenol content in the antioxidant extracts was determined through the Folin‐Ciocalteu method in terms of gallic acid equivalent (GAE). The oxidation stability of fuel samples with the addition of antioxidant extracts was estimated by the Rancimat method in terms of the induction period (IP). As a result, the scavenging effect in percentage for sesame, horse gram, sweet basil, coffee, and peas were 88.76%, 86.51%, 75.28%, 74.15%, and 70.78% at 1500 ppm, respectively. Besides, the total phenol content (mg GAE/100 g) for sesame, horse gram, sweet basil, coffee, and peas observed are 97.37, 39.99, 35.07, 30.15, and 25.25, respectively. More interestingly, adding antioxidants extracted from sesame, horse gram, sweet basil, coffee, and peas could increase the IP of the Jatropha biodiesel‐lemongrass oil binary blend to 9.92, 8.10, 7.74, 7.10, and 4.10 hours, respectively compared to the case of binary blend without antioxidant (only 2.06 hours). In general, the inclusion of natural antioxidants additives increased the oxidation stability of biodiesel, promoting its prolonged storage, and the overall effectiveness of selected natural antioxidants was found to be in the order of sesame > horse gram > sweet basil > coffee > peas. Highlights The incorporation of a binary biodiesel blend reduces the cost of biodiesel synthesis. Replacement of synthetic antioxidant additive with natural antioxidant additive. Natural antioxidant addition enhances the storage stability of binary biodiesel blend.
