“…[43][44][45][46] In low-load circumstances, incorporating decanol into JFME generates wall-wetting and flame-quenching consequences, eventually due to the more significant latent heat of evaporation, resulting in a subsequent decrease in BTE. [47] However, as the in-cylinder temperature increases due to more outstanding atomization and faster flame speed, BTE was enhanced under higher load circumstances. Furthermore, the delay period is prolonged, allowing more fuel to accumulate throughout this time, eventually resulting in more excellent premixed combustion.…”

Biomass‐based biofuel production is a promising solution to the decline of fossil fuels. Prosopis juliflora seed‐derived vegetable oil, known as Prosopis juliflora methyl ester (JFME), offers a potential feedstock for biodiesel. To enhance its properties, the addition of Decanol is investigated, a higher‐order alcohol similar to Diesel. Experiments are conducted on a 5.2 kW compression ignition (CI) engine using JFME blended with different decanol concentrations (5%, 10%, 15%, and 20%). Fourier‐transform infrared spectroscopy and gas chromatography‐mass spectrometry analysis confirm its compliance with fuel standards. The findings reveal that the 20% decanol blend (D20) achieves a brake thermal efficiency of 29.9% at full load, with reduced NO, smoke, and hydrocarbon (HC) emissions compared to diesel. D20 shows NO emissions of 1265 ppm, smoke opacity of 53%, and HC emissions of 69 ppm, while diesel records 1320 ppm, 69%, and 75 ppm, respectively. The CO emissions for D20 are 0.359 vol%, slightly higher due to decanol's higher latent heat of evaporation. Moreover, D20 exhibits improved combustion with a higher mass fraction burnt and faster heat release rates. These results indicate the potential of using JFME blended with 20% decanol as an alternative fuel for CI engines, offering higher performance and reduced emissions.

“…As a result, periodic enhancements to diesel engines are necessary in order to bridge the gap between the requirements for energy and the availability of energy, particularly in the automotive sector. 3,4 Various combustion technologies have been applied to diesel engines, including low-temperature combustion, dualfuel combustion, and the use of alternative fuels with diesel, like bio-diesel. [5][6][7][8][9][10][11] The use of dual-fuel engines is expected to provide a better way to regulate combustion than traditional diesel engines.…”

This investigation used the Diesel‐RK simulation program to carry out a numerical analysis of the effects that dual‐fuel mixes have on the combustion, performance, and emissions of a dual‐fuel diesel engine. It applied the multizone combustion model, and the controlling equations were solved for each individual combustion region. The engine characteristics were examined under the following scenario: it was initially powered by single‐fuel regular diesel (DF), then it switched to dual‐fuel use with 20% biogas, and then it was changed again with the use of 30% dimethyl ether (DME). On this basis, the mentioned biogas and DME ratios were used. The results showed that combustion pressure for the operation of 30% DME and 20% biogas was reduced by 2.45% and 9.57%, respectively, with respect to diesel fuel alone. The Sauter mean diameter (SMD) of the droplets was reduced by 12.6% for 30% DME and 16.2% for 20% biogas. Heat release and brake thermal efficacy (BTE) were reduced slightly with the use of biogas or DME in comparison with DF. The brake‐specific fuel consumption (BSFC) increased by 15.27% and 8.34%, with 30% DME and 20% biogas respectively due to the difference in the energy content of the tested fuels. Nitrogen oxide emissions decreased by 2% and 28% for the operation of 30% DME and 20% biogas, respectively. The summary emission equation (SE), which describes the combination of NOx and PM emissions, decreased by 4.23% and 5.40% with 30% DME and 20% biogas respectively. Based on the results, this paper recommends the use of 20% biogas with diesel rather than 30% DME. The current findings matched well with other scientists' results.
