“…The nitrogen oxide emission with load variation for BD100, BD100 + DMC and diesel is shown in the Exhibit 5. BD100 emits more NOx compared to all test fuels due to the higher temperature of the combustion process which is due to higher oxygen content in BD100 (Saha & Roy, 2023). DMC in the BD100 + DMC blend improves fuel oxidation and minimize ignition delay, resulting in lower NOx emissions than the BD100…”

In this work, diesel engine emissions are studied by adding a cetane improver to the engine fuel. Dimethyl carbonate (DMC) additive is used as a cetane improver. A single‐cylinder, four‐stroke diesel engine is used to test the fuels. Three fuels are selected to run the engine, namely, biodiesel derived from neem oil + 1 vol% DMC (BD100 + 1DMC), BD100, and diesel. BD100 + 1DMC fuel emits a reduced amount of carbon monoxide and unburnt hydrocarbons compared to diesel under the same operating conditions of engine. The level of nitrogen oxides emission for BD100 + 1DMC is slightly higher compared to diesel and significantly lower compared to BD100.

“…The latter corresponds to the complete disintegration of the parent droplet [22,23]. The effective fuel droplet size distribution is enhanced, improving the surface contact area of the fuel molecules with the surrounding air and ultimately leading to a better mixture formation, more optimized combustion, and fewer emissions [24][25][26]. An example of the micro-explosion phenomenon in a fuel droplet is shown in Figure 2.…”

Diesel engines are known for their excellent efficiency and are therefore used in a variety of applications. However, they are also one of the main sources of hazardous emissions such as nitrogen oxides (NOx) and smoke. Water-in-Diesel Emulsion (WiDE) is an alternative fuel that can possibly reduce some of the pollutant emissions without compromising engine performance. The surfactant formulation for WiDE usually follows the one used in water-in-oil (w/o) emulsions, where low hydrophilic–lipophilic balance (HLB) emulsifiers are preferred for better solubility in the diesel phase and stabilization at storage temperatures. However, by using a hydrophilic blend with a non-ionic surfactant, it is possible to develop an optimized formulation at higher fuel temperatures, which occur during an engine’s operating condition, achieving possibly higher benefits. Across the different speeds, the results for the emulsion show 7.57% mean improvement in specific fuel consumption (SFC), 19.14% mean improvement in thermal efficiency (TE), 5.54% mean reduction in carbon dioxide (CO2), 20.50% mean reduction in nitric oxide (NO) and 75.19% mean reduction in smoke levels. However, carbon monoxide (CO) and hydrocarbons (HC) emissions were higher, with a mean increase of 81.09% and 93.83%, respectively.

“…The surfactant assists in creating stable water-in-fuel emulsions by reducing the interfacial tension between the two substances [5]. Different types of surfactants, such as Span 20, Span 60, Span 80, Tween 20, Tween 80, and Triton X100, with different ratios, have been used in several studies [6][7][8][9][10][11].…”

“…Based on their results, E20 exhibited similar in-cylinder pressure and heat release rates to pure diesel fuel, concurrently reducing NOx and PM emissions significantly. In their study, Azimi et al [7] studied water-diesel emulsions as a possible solution to reduce engine pollution. The emulsion fuel varied in water content, ranging from 0% to 10% by volume.…”

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.
