Effect of polyoxymethylene dimethyl ethers on particle properties and diesel particulate filter regeneration

Effect of nano-graphene lubricating oil on particulate matter of a diesel engine

“…Figure 6 respectively shows the changes in particle size distribution of different lubricating oils added to the fuel under different load conditions at the rated speed of 3000 r/min. It can be clearly seen from the figure that the particle size all presents a bimodal logarithmic distribution, with the peaks occurring at 9–19 nm and 69–81 nm, which is basically consistent with the peak position in the literature 44 . The quantity concentration of accumulated particles of MGL25 is significantly higher than that of PLO, and this phenomenon is more obvious at large loads.…”

BaFe1−xNixO3 Catalysts for NOx-Assisted Diesel Soot Oxidation

“…Diesel engines are preferred for these applications because their efficiency and durability are higher than that of gasoline engines [3,4]. However, diesel engines generate pollutants such as particulate matter (also called soot particles) and nitrogen oxides (NO x ), being both highly dangerous for human health and the environment [5][6][7]. Consequently, vehicle emission regulations are becoming more demanding, and the use of after-treatments systems is mandatory.…”

Techno-economic assessment and carbon footprint of processes for the large-scale production of oxymethylene dimethyl ethers from carbon dioxide and hydrogen

“…10 Several studies investigated different blends of OME with diesel fuel to conform to the EN590 standard, which showed a signicant reduction in local emissions for both heavy duty and passenger cars. [11][12][13][14][15][16][17][18][19][20][21][22][23][24] Under certain conditions, even a mixture of 10 vol% OME with diesel can lead to a signicant reduction in NO x and soot emissions. 12 A stoichiometric evaluation showed that already 10 vol% OME blend with diesel will correspond to ca.…”
