“…Sahoo & Jain [83] examined the impact of nano-fuel additives with magnetic fuel conditioning and highlighted that the magnetic field facilitated better atomization of fuel particles. Niaki et al [84] found that magnetic fuel conditioning improved fuel economy by 4% to 12% and reduced emissions on a multi-cylinder gasoline engine.…”

Since the early 1980s, research on magnetically enhanced combustion has garnered significant attention and importance. These studies have primarily focused on investigating the influence of magnetic fields on the combustion process of fuels. During this period, studies that highlighted the potential to alter molecular structures and properties through powerful magnetic fields emerged as significant contributors to the field. Simultaneously, the effects of magnetic fields on flame formation, behavior, and propagation have been thoroughly explored through various combustion models and experiments. The significance of these investigations lies in their contribution to a better understanding of the effects of combustion on energy efficiency and emission profiles. The capability of strong magnetic fields to modify molecular arrangements can enhance fuel atomization, promoting the creation of a more homogeneous fuel-air mixture. Additionally, the potential of magnetic fields to influence the reaction rates and behavior of gas molecules holds promise for achieving improved combustion and reduced emission production. Investigations have also focused on how chemical reactions of fuels are altered under magnetic fields and how these changes translate into motor performance. Specifically, research has highlighted how chain reactions such as gas combustion and explosion can be altered under magnetic fields, potentially reducing the production of harmful emissions like carbon monoxide, hydrocarbons, and nitrogen oxides. In this context, a comprehensive exploration of various aspects such as flame formation, engine performance, emissions, and explosion intensity under the influence of magnetic fields is of paramount importance. Future endeavors can potentially yield a more profound and precise understanding of the effects of magnetic fields on combustion processes and enable the utilization of this knowledge for more efficient and cleaner energy production across different industrial applications.

“…As the researchers switching over to green energy in the future, alternative fuels are becoming increasingly crucial. The availability of the alternative fuel in a country is the most important factor to consider when choosing an alternative fuel [1]. Typical automotive fuels such as gasoline and diesel, emit harmful pollutants such as CO2, nitrogen oxides (NOx), particulate matter (PM) and soot, all of which contribute to the environmental pollution [2].…”

The study explores the impact of ammonia and DME on the combustion / performance characteristics and exhaust emissions of a dual-mode IDI diesel engine without making any major alterations to the engine. Fortran-77 programming is used to develop a computer simulation program. The findings show that blending in dual mode raises pre and main chamber temperatures and pressures, as well as IMEP and BP, but lowers BSEC as ammonia substitution increases from 5% to 25%. Blending (diesel + ammonia) increases BP by 15.93 percent, 37.25 percent, and 72.42 percent in dual mode at 20%, 40%, and 60% NG substitutions respectively and blending (diesel + DME) increases BP by 17.79 percent, 40.17 percent, and 76.99 percent in dual mode at 20%, 40%, and 60% NG substitutions respectively

“…Kahila et al [5] simulated the ignition and combustion process of a diesel pilot-ignited natural gas-air mixture using large eddy simulation and classified the combustion process into five phases. Khatamne et al [6] investigated the in-cylinder pressure variations with different loads, different natural gas premixing ratios and heat release rate variations. The lower reactivity of the natural gas Energies 2023, 16, 7899 2 of 16 causes a delay in the start of combustion at high natural gas premix ratios.…”

The effects of six control parameters, intake valve opening timing (IVO), exhaust valve opening timing (EVO), compression ratio (CR), engine speed, intake temperature, and intake pressure on engine output power, indicated specific fuel consumption (ISFC), and nitrogen oxides (NOx) emissions, are analyzed through engine simulation. The six parameters were categorized into two groups based on the degree of influence: high influence (EVO, speed and intake pressure) and low influence (CR, IVO and intake temperature). The relationship between these two groups of parameters and power, ISFC and NOx emissions was explored. Optimization was carried out for each of the two groups of parameters, and the optimization of the high impact parameters resulted in a higher diversity and wider distribution of the solution set. On the other hand, the optimization of the low-impact parameters resulted in a more concentrated distribution of the solution set, while better reflecting the trade-off between the optimization objectives. For the optimal solutions for both sets of parameters, the high-impact parameters provided significant optimization performance compared to the standard operating conditions. Although power and ISFC were optimized, the optimal solution for the low-impact parameter performed poorly with a significant increase in NOx emissions. Therefore, the parameters should be evaluated for optimization using high impact parameters to improve engine performance.
