“…There is a decrease in the temperature of the torch due to the suppression (blocking, ballasting) of the zone of active combustion with water vapor at larger sizes of the dispersed phase. In this case, the NO x concentration decreases to 113 mg/m 3 [11,12]. Studies of the fractional composition of PM in WFE combustion products revealed that the fineness of PM does not depend on the size of the WFE dispersed phase.…”

“…It contributes to more complete combustion and a decrease in the content of oxides in gases. According to Wang, Z. et al the concentration of particulate matter (PM) depends on the fineness of the emulsion too [11,12]. The curve of the change in PM concentration has a pronounced minimum of 19 mg/m 3 within the range of the emulsion dispersed phase sizes from 35 to 45 µm.…”

The application of water-fuel emulsion (WFE) in internal combustion engines enables to reduce the consumption of sulfurous fuel oils, thereby protecting the environment from emissions of sulfur and nitrogen oxides, as well revealing a great potential for the heat utilization of exhaust gases. The efficiency of utilization of exhaust gas heat in exhaust boilers (EGB) depends on their temperature at the outlet of EGB, id est. the depth of heat utilization. Exhaust gas temperature is limited by the rate of low-temperature corrosion (LTC), which reaches a level of 1.2 mm/year at the wall temperature of about 110 °C for the condensing heat exchange surfaces (HES) and reduces the reliability of the HES operation. Therefore, decreasing the corrosion rate of condensing HES at wall temperature below 110 °C to an acceptable level (about 0.2 mm/year) when undergoing WFE combustion will make it possible to reduce the exhaust gas temperature and, consequently, increase the efficiency of EGB and fuel saving during the operation of the ship power plant. The aim of the research is to assess improvements to the reliability, durability and efficient operation of condensing HES in marine EGB undergoing WFE combustion in a diesel engine based on experimental studies of the LTC process. A special experimental setup was developed for investigation. The use of WFE with a decreased wall temperature of HES below 80 to 70 °C would improve the reliability of the EGB along the accepted service life, increase the lifetime of the HES metal by almost six times as well as the overhaul period, and reduce the cost of repairing condensing HES. Furthermore, due to the reducing corrosion rate under WFE combustion, the application of low-temperature condensing HES makes it possible to enhance the efficiency of deeper exhaust gas heat utilization and provide sustainable efficient operation of a diesel engine plant on the whole at a safe thermal and environmentally friendly level.

The current situation of high prices of petroleum oil needs to be studied to find alternative fuels that can reduce some emissions. The use of biodiesel in a mixture of diesel fuel is an alternative to address the global crisis related to the depletion of petroleum reserves. Moreover, mixing biodiesel into diesel fuel can reduce some emissions such as CO, HC, and particulate matter. However, the NOx emissions are still high. The purpose of this study is to analyze the performance and emissions using diesel fuel with a mixture of deionized water (ratio 60:40) in comparison with Indonesian diesel fuel (B30). Test fuels are conducted in a diesel engine with different loads of idle, 36% and 68% with the engine rotation of 1500 rpm. The results show that mixing 40% deionized water with diesel fuel can reduce emissions of HC up to 0,29%, and NOx by 21,56% than diesel fuel at 68% load. Moreover, the specific fuel consumption can be down up to 3% more than diesel fuel. Therefore, deionized water fuel can be the solution to make better fuel properties, can reduce emissions, and be friendly to the environment.

“…This study aims to investigate diesel engines' performance characteristics and emissions by mixing water, Al 2 O 3 nanoparticles, and diesel fuel at two stages of experimental work. 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].…”

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.
