“…This behavior is explained by a greater total energy discharge at higher loads with a constant frictional power loss; so, net power output increases and BSFC decreases. Another explanation would be that higher cylinder pressure and temperature (at high loads) improve combustion efficiency [35]. With an increasing water ratio in fuel emulsion, there is also an increase in BSFC, as presented in Figure 13a.…”

“…Based on previous studies, using a water-diesel emulsion effectively reduced NOx emission [1,3,6,[24][25][26][27][28][29][30][31]. In contrast, many studies showed a decrease in brake thermal efficiency (BTE) and an increase in brake-specific fuel consumption (BSFC) with an increasing water ratio in the emulsion fuel due to a lower heating value [32][33][34][35][36][37][38]. To combat this issue, Al 2 O 3 nanoparticles are chosen as the combustion enhancer and mixed with the water-diesel emulsion fuel.…”

This study aims to assess the impact of the water ratio and nanoparticle concentration of neat diesel fuel on the performance characteristics of and exhaust gas emissions from diesel engines. The experimental tests were conducted in two stages. In the first stage, the effects of adding water to neat diesel fuel in ratios of 2.5% and 5% on engine performance and emissions characteristics were examined and compared to those of neat diesel at a constant engine speed of 3000 rpm under three different engine loads. A response surface methodology (RSM) based on a central composite design (CCD) was utilized to simulate the design of the experiment. According to the test results, adding water to neat diesel fuel increased the brake-specific fuel consumption and reduced the brake thermal efficiency compared to neat diesel fuel. In the examination of exhaust emissions, hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (NOx) in the tested fuel containing 2.5% of water were decreased in comparison to pure diesel fuel by 16.62%, 21.56%, and 60.18%, respectively, on average, through engine loading. In the second stage, due to the trade-off between emissions and performance, the emulsion fuel containing 2.5% of water is chosen as the best emulsion from the previous stage and mixed with aluminum oxide nanoparticles at two dose levels (50 and 100 ppm). With the same engine conditions, the emulsion fuel mixed with 50 ppm of aluminum oxide nanoparticles exhibited the best performance and the lowest emissions compared to the other evaluated fuels. The outcomes of the investigations showed that a low concentration of 50 ppm with a small amount of 11 nm of aluminum oxide nanoparticles combined with a water diesel emulsion is a successful method for improving diesel engine performance while lowering emissions. Additionally, it was found that the mathematical model could accurately predict engine performance parameters and pollution characteristics.

“…This allows for a simultaneous reduction in nitrogen oxides and exhaust smoke. It is possible to produce emulsion fuel from non-biodegradable shopping bags (PGB) [7]. The research showed that using the water-oil emulsion derived from PGB reduces smoke and nitrogen oxide emissions.…”

This article discusses the potential applications of the Fuel Shot liquid catalyst in compression ignition (CI) engines for reducing toxic substances in exhaust gases. Incorporating catalysts into fuel can optimize the combustion process, consequently reducing the emission of toxic substances into the atmosphere. Toxic compounds, such as nitrogen oxides, particulate matter, and hydrocarbons, adversely affect flora and fauna. Various methods are known for reducing their concentration in engine exhaust gases, one of which is the Fuel Shot liquid catalyst. The authors conducted experiments on a Fiat 1.3 JTD engine with a Common Rail system. The results indicate that the application of the liquid catalyst reduces the content of nitrogen oxides and hydrocarbons in the exhaust gases and slightly decreases fuel consumption. Additionally, investigations were carried out on the engine’s injection apparatus, which was fueled with modified fuel. The findings demonstrate that the fuel additive does not affect the wear of precision parts of fuel injectors and high-pressure pumps.
