Low-temperature combustion paired with the use of carbon-free ammonia and carbon-neutral biofuels is a novel approach for improving performance, reducing greenhouse gases, and reducing regulated emissions. Reactivity-controlled compression ignition (RCCI), a low-temperature combustion technology, dramatically reduces NOx and smoke emissions compared to traditional engines. Ammonia can be projected as a good transit fuel in the journey toward achieving net zero emissions and cleaner energy. This study examines the impact of ammonia energy premixing fraction (AEPF) (20, 30, 40, and 50%) as a lowreactive fuel (LRF) and algal biodiesel as a high-reactive fuel on the performance and emission characteristics of a single-cylinder, water-cooled 3.5 kW CI engine at a constant speed of 1500 rpm under various loading conditions. The research results indicate that the 40% ammonia share RCCI mode exhibited a reduction in carbon dioxide (CO 2 ) by 14.16%, nitrogen oxide (NOx) by 22.6%, and smoke by 42.1%, with an 11.5% improvement in thermal efficiency compared to the neat biodiesel-fueled conventional engine. Furthermore, the analytical hierarchy process (AHP) will be used in conjunction with the technique for order of preference by similarity to ideal solution (TOPSIS) of multiple criteria decision-making techniques to determine the optimal energy share in the RCCI combustion with the goal of achieving superior thermal efficiency and lower emissions. According to the AHP-TOPSIS study findings, AEPF40 is the best choice for all engine loads.

“…Isopropyl alcohol has been used as a substitute in a variety of studies . It was discovered that enhancing the concentrations of n -heptane–isopropanol in a homogeneous charge compression ignition engine decreases both the cylinder pressure and the volume of heat released . When isopropanol is mixed with diesel, it has a longer delay time, less NO x and CO 2 emissions, and a faster combustion rate …”

Regulations governing pollution, declining fossil fuel supply, and technological breakthroughs in renewable fuels all have a profound influence on the development of alternative fuels. This current research focuses on the influence of nanoadditives with alcohol in an exhaust gas recirculation-cooled engine. As nanoadditives have high thermal conductivity and alcohol has high oxygen content, they work synergistically to speed up the catalytic process and increase the combustion rate. The areca nutshell-reduced graphene oxide with a mass fraction of 25 pmm was ultrasonically blended with two isopropanol–diesel mixtures 10% isopropanol + 90% diesel (IDR10) and 20% isopropanol + 80% diesel (IDR20), respectively, and tested in a single-cylinder, 4-stroke internal-combustion engine at a typical injection timing of 23° TDC with an EGR rate of 20%. The results of experiments showed that IDR10 has better combustion and emission parameters than other fuel blends. Compared to other biodiesel blends, the IDR10 blend has 2.3% less BSFC and 2.45% more BTE. The IDR10 blend has lower HC emissions by 42.85%, CO emissions by 33.34%, NO x emissions by 2.42%, and smoke emissions by 15.4%.

“…Light naphtha is composed of pentane and slightly heavier material. It is produced from crude oil distillation or natural gas liquid (NGLs) separation and, in this case, called natural gasoline or pentanes plus [12,19,[25][26][27]. Light naphtha is often blended directly with gasoline in the refinery up to 5% blending ratio due to its low octane number and relatively high vapour pressure, which limits utilization at a higher percentage [19].…”

Fuel quality is an important indicator for the suitability of alternative fuel for the utilization in internal combustion (IC) engines. In this paper, light naphtha and fusel oil have been introduced as fuel additives for local low octane gasoline to operate a spark ignition (SI) engine. Investigated fuel samples have been prepared based on volume and denoted as GN10 (90% local gasoline and 10% naphtha), GF10 (90% local gasoline and 10% fusel oil), and GN5F5 (90% local gasoline, 5% naphtha and 5% fusel oil) in addition to G100 (Pure local gasoline). Engine tests have been conducted to evaluate engine performance and exhaust emissions at increasing speed and constant wide throttle opening (WTO). The study results reveal varying engine performance obtained with GN10 and GF10 with increasing engine speed compared to local gasoline fuel (G). Moreover, GN5F5 shows higher brake power, lower brake specific fuel consumption, and higher brake thermal efficiency compared to other investigated fuel samples over the whole engine speed. The higher CO and CO2 emissions were obtained with GN10 and GF10, respectively, over the entire engine speed and the minimum CO emissions observed with GN5F5. Moreover, the higher NOx emission was observed with pure local gasoline while the lowest was observed with GF10. On the other hand, GN5F5 shows slightly higher NOx emissions than GF10, which is lower than GN10 and gasoline. Accordingly, GN5F5 shows better engine performance and exhaust emissions, which can enhance the local low gasoline fuel quality using the locally available fuel additives.
