“…Reason may be the high calorific value and faster flame speed of hydrogen and oxygen buffering effect of nanoparticle which enhanced the combustion process and efficiency. [6,11] Figure 3 demonstrates the CO emission change with engine speed. Incomplete combustion can be the main reason of CO formation.…”

In this study, effects of iron oxide (Fe 3 O 4 ) and hydrogen (H 2 ) additions into 20% sunflower biodiesel + 80% diesel (B20) operated compression ignition engine performance and emissions are evaluated. Diesel fuel (D) is selected as a reference fuel for comparison purpose. Reduced performance level with B20 can be recovered with use of nanoparticle and hydrogen due to their superior combustion characteristics. In comparison to diesel, B20 mixture has caused to reduction on power by 6.44% while addition of nanoparticle and hydrogen (H_B20_Fe) have increased power by 5.76%. B20 mixture led to decrease carbon monoxide (CO) emission by 7.92% whereas nanoparticle and hydrogen addition have caused further decrement by 12.35% compared to diesel. Diesel shows best nitrogen oxides (NO x ) emission characteristics of all. Increment levels are 7.24% and 12.94 for B20 and H_B20_Fe, respectively.

In recent years, the application of nanoadditives in biofuels is gaining much attention due to their increase in thermophysical properties such as high surface area, thermal conductivity, and mass diffusivity. However, lack of stability, high additive cost, and difficult recovery from engine exhaust are the high-priority and demanding characteristics, which may be chosen by many researchers. In this regard, the most promising nanoadditives are magnetite nanoparticles, having a high-specific area, strong magnetic response, control over the particle size and, most importantly, easy and rapid separation from exhaust gas by applying external magnetic bars. Moreover, it can be easily diluted into biodiesel, and thus, it can collect the advantages of biodiesel in water emulsion. From the literature survey, it is found that there is a lacuna in the synthesis and performance of magnetite nanofuels for internal combustion engine applications. Thus, the present study aims to epitomize the research findings related to the synthesis, characterization, stability, and properties of biodiesel/diesel-based fuels blended with magnetite nanoparticles and the influence of the magnetite nanofuels on engine performance. The study shows that the addition of nanoparticles to biodiesel has positive effects in reducing harmful emissions such as carbon black, smoke opacity and NOX, with improved thermal efficiency and fuel consumption.

“…In addition, ethanol has a high laminar flame propagation velocity, which could significantly improve diesel engine combustion conditions and reduce engine particulate emissions [20]. Some previous studies have also shown that the use of alternative fuels will have a great impact on the combustion performance and exhaust emissions of diesel engines [21,22]. Many regions have adjusted energy policies in the search for clean fuels [23,24].…”

Combustion Performance and Emission Characteristics of Marine Engine Burning with Different Biodiesel

Ship emissions are one of the main sources of air pollution in port cities. The prosperous maritime trade has brought great harm to the air quality of port cities while promoting the development of the world economy. During the berthing process, ship auxiliary machines emit a large amount of air pollutants, which have a great impact on air quality and public health. Alternative marine fuels are being studied and used frequently to reduce ship emissions. This research was carried out to investigate the gaseous and particles emission characteristics of a marine diesel engine during the application of experimental biodiesel fuels. To study the influence of mixed fuels on engine performance, measurements were made at different engine loads and speeds. Different diesel fuels were tested using various ratios between biodiesel and BD0 (ultra-low sulfur diesel) of 0%, 10%, 30%, 50%, 70%, 90%, and 100%. The results indicated the use of biodiesel has little influence on the combustion performance but has a certain impact on exhaust emissions. The octane number and laminar flame speed of biodiesel are higher than those of BD0, so the combustion time of the test diesel engine is shortened under the mixed mode of biodiesel. In addition, a high ratio of biodiesel leads to a decrease of the instantaneous peak heat release rate, causing the crank angle to advance. As the biodiesel blending ratio increased, most of the gaseous pollutants decreased, especially for CO, but it led to an increase of particle numbers. The particle size distribution exhibits a unimodal distribution under various conditions, with the peak value appearing at 30–75 nm. The use of biodiesel has no effect on this phenomenon. The peak positions strongly depend on fuel types and engine conditions. The particulate matter (PM) emitted from the test engine included large amounts of organic carbon (OC), which accounted for between 30% and 40% of PM. Whereas the elemental carbon (EC) accounted for between 10% and 20%, the water-soluble ions components accounted for 6–15%. Elemental components, which accounted for 3–8% of PM emissions, mainly consisted of Si, Fe, Sn, Ba, Al, Zn, V, and Ni. Generally, biodiesel could be a reliable alternative fuel to reduce ship auxiliary engine emissions at berth and improve port air quality.
