“…The reduction in C−H ratio, superfluous oxygen composition, and absence of sulfur content in the VNSOME blends are the important causes of the effective reduction in smoke emissions. 49,56,57 The disparity of carbon dioxide (CO 2 ) emission of the test fuels (VNSOME5, VNSOME10, VNSOME15, VNSOME20, and diesel fuel) at different BPs is exhibited in Figure 11. When the load increases in the test, the engine emits higher CO 2 emissions for all the test fuels.…”

The rapid growth in industrialization steadily increased the energy demand. The world’s population ultimately depends on petroleum as a major share of fuel for transportation and industrialization. Even though it is widely used in various sectors, its emission into the atmosphere creates serious problems in the form of acid rain, smog, etc. This present experimental investigation highlights the utilization of Vachellia nilotica seed oil methyl ester (VNSOME) synthesized from Vachellia nilotica seed oil (VNSO) fueled in a diesel engine to assess the emission and performance characteristics. VNSOME is produced using the alkaline catalyst (NaOH) transesterification technique. Four different fuel blends of biodiesel, namely, VNSOME5, VNSOME10, VNSOME15, and VNSOME20, were prepared and fueled in an unmodified engine. The engine brake thermal efficiency is lower, the brake-specific fuel consumption (BSFC) using VNSOME20 is higher, and the temperature of exhaust gas emitted after combustion is increased. The thermal efficiency is reduced by 7.34% with increased BSFC and exhaust gas temperature (EGT) of 9.3 and 14.28%, respectively, as compared to diesel fuel. Similarly, using an optimized biodiesel blend (VNSOME20), the emission emitted such as HC and CO is reduced by 19.14 and 22.2%, respectively. However, the engine fueled with the VNSOME20 biodiesel blend increased the level of CO2 and NO x emitted into the atmosphere when compared to diesel fuel.

In the present study, newly developed waste cooking biodiesel (B20) with nanoparticles (Al2O3) was tested to optimize the response of a CRDI single‐cylinder four‐stroke VCR engine at various input parameters. A response surface methodology (RSM) was used to investigate the impact of various input parameters, such as injection pressure (IP), load, compression ratio (CR), and nanoparticle concentration as fuel additives on engine responses, including brake thermal efficiency (BTE), specific fuel consumption (SFC), carbon dioxide (CO), hydrocarbon (HC), and oxide of nitrogen (NOX) emissions. The RSM found the best suitable value of all input parameters at which the engine produced maximum performance and minimum emissions. Accordingly, the optimal setting of all input parameters was identified as a nano biofuel blend ratio of 1.10, IP of 656 bar, CR of 18.50, and a load of 7.10 kg. At this combination of input parameters, the optimal BTE, SFC, CO, HC, and NOx are 23.6%, 0.3461 kg/kWh, 0.0281%, 25.3756 ppm, and 536.41 ppm respectively. The predicted optimum value from RSM is compared with the experimental value for validity and found a fair agreement.

The compression‐ignition properties of crude Jatropha and camphor oil blends with di ethyl ether (DEE) added is covered in this research. Six fuel samples are made based on volume: 90% C70J30 with 10% diethyl ether (C70J30 + 10% DEE), 90% C30J70 with 10% di‐ethyl ether (C50J50 + 10% DEE), 70% Camphor oil with 30% crude Jatropha oil (C70J30), 50% Camphor oil with 50% crude Jatropha oil (C50J50), 30% Camphor oil with 70% crude Jatropha oil (C30750). A four‐stroke, one‐cylinder, naturally aspirated, compression‐ignition engine operating at a constant 1500 rpm with a load range of 0%–100% with a 25% interval is used for the experiment. According to test findings, the C70J30 + 10% DEE has the lowest brake‐specific energy consumption of 11.68 kJ/kWh, the maximum energy efficiency of 62.56%, and the highest thermal efficiency of 30.81%. Compared to the other biofuels examined, this puts it more in line with diesel. Additionally, blends of crude Jatropha oil and camphor oil showed at least 4.46 g/kWh of CO, 0.259 g/kWh of HC, and 74% of smoke opacity when DEE was added. However, it raises CO2 to 0.792 kg/kWh and NO to 9.54 g/kWh. The greatest peak pressure and quickest heat release are produced by adding more DEE as a fuel additive and using a larger percentage of camphor oil. It also increases the coefficient of variation of the peak pressure throughout 100 cycles. All things considered, the C70J30 + 10% DEE's CI engine features are better.
