Potentials of OME/diesel blends for stationary power production – Improving emission characteristics of a diesel CHP unit

Particle emissions of a heavy-duty engine fueled with polyoxymethylene dimethyl ethers (OME)

“…24 Popp et al also observed this effect with OME-diesel-blends on a heavy-duty engine. 25 Investigations with an OME 3-5 mix in a single-cylinder research engine demonstrated particle emissions in the so-called sub-23 nm range with a peak around a size of 10 nm. 26,27 Neither study included a description of the sampling system, so it is unknown whether or not the results contained volatile particles.…”

Experimental and numerical study on the effect of oxymethylene ether-3 (OME3) on soot particle formation

“…OMEs have shown positive effects in terms of reducing CO, unburned hydrocarbons and soot particle emissions when used as an additive to diesel in engine experiments [19][20][21][22][23][24][25]. A higher rate of exhaust gas recirculation (EGR) can be applied to reduce NOx emissions [23,26]. Investigations on OME1 as an alternative fuel indicate that soot is suppressed entirely [27].…”

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

“…In addition to the energy efficiency of the process routes, the material balance was assessed, and the performance was indicated by two parameters. The rst parameter, h C , reecting the carbon efficiency, i.e., the ratio of carbon atoms, C, in the feedstock and the carbon atoms in the OME 3-5 product stream, is dened in eqn (18). The second parameter, h mass , considers the mass ow rates, i.e., the ratio of the OME 3-5 product mass ow rate with respect to the feedstock mass ow rate, as dened in eqn (19).…”

“…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.…”
