“…Carbon dioxide (CO 2 ) emission is produced when the fuel is burned it releases CO 2 as a byproduct of combustion. A hydrocarbon fuel should ideally only burn to produce CO 2 and water vapor 56–58 . Figures 17A–C and 18A–C indicates the change of CO 2 concerning Load with IT/CR.…”

“…A hydrocarbon fuel should ideally only burn to produce CO 2 and water vapor. [56][57][58] Figures 17A-C and 18A-C indicates the change of CO 2 concerning Load with IT/CR. This rise in CO 2 emission was noticed as the load increased which led to an increase in fuel consumption and the burning of fuel will have CO 2 as a byproduct of combustion.…”

The manuscript addressed experimental work related to microalgae‐based biodiesel blend B20, that is, 20% algae biodiesel and 80% diesel, as an alternative fuel as a possible source to power diesel engines. The physiochemical characteristics of this B20 blend were almost in line with diesel fuel as per American Society for Testing and Material standards. Coupled experimentation related to variations in compression ratio (CR) 17, 19, and 21 and fuel injection timing (IT) of 21°, 23°, and 25° before top dead center (bTDC) with load variations noted on diesel engines. We observed that, at full load, CR21 and 23° bTDC fuel IT, the brake thermal efficiency parameters rose significantly, whereas brake‐specific fuel consumption, and combusted flue gas temperatures also plummeted. The CO, HC, and smoke opacity emission for the B20 blend at CR21 and FIT23 has decreased by 30.52%, 33.33%, and 32.96%, respectively. At full load conditions, NOx emission for B20 biodiesel at CR21 was increased compared with the standard setting and compared with diesel it was increased by 6.46%.

Assessment of alternate fuel is categorized on thermophysical aspects and performance—emission derived due to its combustion. Data derived from such analysis is short as the energy expenditure to available chemical exergy of fuel is rarely studied. The study of energy derived from fuel energy gives a detailed picture of fuel efficiency and broadens the field of fuel search criteria. The current article aims to find the thermodynamic effects in terms of energy and exergy utilization of neem biodiesel blends and nickel oxide nano additive dosed neem biodiesel blends. Neem biodiesel was transesterified using standard procedures and analyzed using gas chromatography and mass spectroscopy. Later, neem biodiesel was blended with diesel in three volumetric proportions, that is, NB25, NB50, NB75, and pure Neem Oil Methyl ester was investigated as an engine fuel, and later synthesized nickel oxide nano additives of 25 mg/L was added to all the above fuels and further studied for energy, exergy utilization on a TV‐1 VCR engine test rig under varying engine CR. Nickel oxide additives were manufactured using homogenous addition method and were thoroughly studied for formation and presence of constituents using XRD, FE‐SEM, and EDS methods. The usage of nano additives does prove reduction in exergy destruction and entropy generation for NB25 base blend with 25 mg/L NiO leading to a reduction of 8.2% and 9.7% when compared to base blends. Also, the emission found for hydrocarbon, and carbon monoxide for all base fuel blends reduced by an average of 16.8% and 7.35%.

The search for an effective solution to improve performance and emission characteristics of internal combustion (IC) engines used in the commercial sector is regarded as one of the most important and essential issues in recent years due to increasing levels of pollution. Nanoparticles with their additive ability to increase fuel reactivity and atomization, due to their large surface area and high heat transfer coefficient, can improve the performance and emission characteristics of a fuel. This review highlights the use of nanoparticles as fuel additives to enhance the emission and performance characteristics of IC engines. Detailed comparisons of performance, emission, and combustion characteristics of IC engines using fuels blended with nanoparticles have been done. Nanoparticles were observed to be an oxygen buffer for fuel combustion and boost fuel atomization, thus enhancing engine performance. While alumina exhibited a decrease in levels of HC and CO but a considerable increase in NOx, graphene nanoparticles and ceria were found to be particularly effective in enhancing engine performance. Detailed study has been done on other nanoparticles, including metal‐oxide, nonmetal‐oxide as well as carbon nanoparticles. Overall, the use of nanoparticles can enhance the thermophysical characteristics of fuels, improving the emission and performance characteristics of engines. The review suggests that selecting the right dosage and variety of nanoparticles is crucial for optimizing engine performance, and thus directly helps in tackling the ongoing pollution problem.
