Summary: This study investigates the use of cyclohexanol-diesel blends in diesel engines. The results show that the blends have a longer ignition delay and a shorter combustion duration, and increase NOx emissions. However, with the appropriate blending ratio and injection timing, the blended fuel can reduce particulate emissions.

Summary: This study investigates and compares the effects of blended fuels with different alcohol substitution ratios on the combustion, performance, and emission characteristics of a diesel engine. The results show that the D80M10B10 blended fuel is the most beneficial in improving cylinder pressure, prolonging ignition delay, and shortening combustion duration. Additionally, the addition of alcohol fuels reduces soot, HC, and CO emissions, but increases NOx emissions.

Summary: The experiments conducted on a high pressure common-rail diesel engine using different fuel blends showed that increasing n-pentanol concentration in diesel/n-pentanol mixtures led to higher soot oxidation reactivity. The addition of EHN to DP30 fuel resulted in varying levels of soot oxidation reactivity changes. There was a nonlinear correlation between soot reactivity and nanostructure, indicating that other factors like active surface area and surface functional group could also influence soot oxidation reactivity.

Summary: This research investigates the impact of renewable fuels, including three types of biodiesel and ethanol, on the physical properties and structural characteristics of particulate matter (PM) emitted from a diesel engine. Three biodiesel blended fuels (10% grape seed biodiesel, 10% spent coffee ground biodiesel, and eucalyptus oil biodiesel) and one ethanol blend (9% ethanol and 1% biodiesel) were tested. The results show that both biodiesel blends and ethanol blend affect the properties of PM compared to pure diesel, with biodiesel blends having a slightly weaker influence than ethanol blend. Among the biodiesel blends, grape seed biodiesel has the greatest impact on the reduction of PM mass, making it a promising renewable fuel for diesel engines.

Summary: The effect of microstructure of biodiesel combustion particulate matter (PM) on the extinction characteristics was investigated. The results show that combustion of biodiesel can significantly reduce PM emissions. Biodiesel PM has smaller particle size and higher aggregation degree compared to diesel PM, resulting in weaker light absorption capacity. The quantity concentration of biodiesel PM decreases and the fractal dimension increases with decreasing iodine number of biodiesel, leading to the formation of more complex agglomerates and a consequent reduction in extinction coefficient.

Summary: This work investigated the effects of different fuel blending ratios on the spray, combustion, and emission characteristics of a diesel engine fueled with diesel/methanol/n-butanol blended fuel. The results showed that blended fuel had longer ignition delay, higher cylinder pressure, and higher peak heat release rate compared with diesel. The blended fuel also reduced NOx, CO, soot, and HC emissions.

Summary: With the global emphasis on environmental protection and carbon neutrality, there is a need for reductions in pollutants such as carbon dioxide, nitrogen oxide, and particulate matter. Diesel engines are a major contributor to particulate matter pollution, and diesel particulate filter (DPF) technology has proven to be effective in controlling soot. This review discusses the exacerbating effect of particulate matter on human infectious diseases, the latest developments in DPF performance, soot catalytic oxidant schemes, and areas for future research.

Summary: In this study, bioethanol production was increased by optimizing the conditions for commercial Saccharomyces cerevisiae on hydrolysate obtained from the enzymatic saccharification of Aspergillus niger. Large-scale production of bioethanol was achieved, and the produced bioethanol was characterized using GC analysis and H-1 NMR. The testing of new fuel blends showed that bioethanol addition improved engine performance but led to increased emissions in certain ratios.

Summary: This study investigates the performance and emissions of a diesel engine fueled by coal-based diesel fuels and their blends with polyoxymethylene dimethyl ethers (PODEn). The results showed that the coal-based diesel blends had slightly lower output torques and powers compared to petroleum diesel fuel. The addition of PODEn improved emission characteristics but reduced the engine power and torque.

Summary: The chemistry of soot particles plays a crucial role in the emissions of engines, specifically in relation to soot growth and oxidation behaviors. Adding methanol to diesel fuel is believed to alter these behaviors, but the exact mechanisms are not well understood. This study characterized the chemical features of soot emissions from a methanol-diesel blend fueled diesel engine, revealing the impact of methanol blending content on the surface and bulk species of the soot particles under different engine load conditions.
