“…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. Preuß et al observed an increase of this sub-23 nm mode with increasing mixing ratios of OME 3-5 in blends with hydrogenated vegetable oil (HVO) and rapeseed methyl ester used as diesel reference fuels, but also without specifying the sampling system.…”

“…A 20% (v/v) admixture of OME 3-4 into diesel fuel that meets the EN 590 B7 norm requirements results in a varied (throughout the engine operating range) reduction of the generated soot particulate mass, which can be found in the range of 50-80% of the original value [27]. This effect has been confirmed multiple times in the studies of mixtures containing 5-35% (v/v) OME 3-5 [2,9,20,25,31,35]. However, in order not to exceed the limits specified in EN 590, the maximum admixture of OME 3-5 must not exceed 5-7% (v/v).…”

The article explains the differences between synthetic fuels of first and second generation. The potential of e-fuels to reduce GHG emissions was indicated. The application requirements that synthetic fuels need to meet in order to be used for powering internal combustion engines have been described. The possibility of using synthetic fuels as "drop-in" fuels, in blends with conventional petroleum-derived fuels as well as by themselves was discussed. E-fuels developed and optimized to power compression ignition and spark ignition engines were characterized. The possibilities of synthetic fuels to reduce emissions of regulated and unregulated exhaust components and to improve the work and operational parameters of the engine were also analyzed using the research carried out so far as basis. At the end of the article, forecasts for synthetic fuels development and applications were presented in the form of a SWOT analysis.

“…The composition varied from OME2 to OME6 or from OME3 to OME5. 10,13,18 These mixtures have the advantage that they are close to diesel standards and can be produced by various synthesis. 22,24,27−30 The actual technical challenges consist of optimizing the process yields of existing synthesis routes as well as using renewable resources like biomass, residues, and wastes.…”

“…Poly(oxymethylene) dimethyl ether is a collective term that contains a number n of CH 2 –O units . The number of units discussed in the literature for engine application ranges from n = 1 (OME1, also known as DMM) to n = 6 (OME6). − ,− The molecular structure of OME is shown in eq . The fuel properties of OME1–OME6 are different from those of diesel fuel, as shown in Table . Many of the parameters do not fit the European diesel fuel standard EN 590 but are largely comparable. , The density of all OME variants is above the EN 590 standard, and the kinematic viscosity of OME1–OME4 as well as the flash point of OME1 and OME2 is below EN 590.…”

“…Often OME mixtures are used for engine tests instead of individual OME components. The composition varied from OME2 to OME6 or from OME3 to OME5. ,, These mixtures have the advantage that they are close to diesel standards and can be produced by various synthesis. ,,− The actual technical challenges consist of optimizing the process yields of existing synthesis routes as well as using renewable resources like biomass, residues, and wastes . While engine combustion of OME seems to be promising, the possibilities of ecologically sustainable and economically sensible production have yet been sufficiently clarified up to now because of the low technology readiness level.…”

While a large part of traffic volume can be electrified to avoid local pollutant emissions, some applications will still require an internal combustion engine as an energy converter in the future. Construction machines such as vibratory plates, excavators, or emergency generators are examples of such applications. In order to reduce or avoid the pollutants of the remaining internal combustion engines, exhaust aftertreatment systems or synthetic fuels can be implemented. One category of these literature-discussed fuels is poly(oxymethylene) dimethyl ether (OME). In this work, neat OME as well as four OME− diesel blends and conventional diesel fuel as reference were investigated according to the material compatibility of two elastomers (NBR and FKM) and long-term storage stability of the fuel itself. The material compatibility of OME according to both elastomers NBR and FKM is difficult. The tensile stress test (DIN 53504), the Shore hardness (ISO 7619-1), and the compression set (ISO 815-1) show significant changes for neat OME compared to the diesel used elastomers. In addition, the change of mass and volume of the elastomers (DIN ISO 1817) are up to 75 wt % and 140 vol % higher compared to diesel fuel. Only FKM specimens, which were submerged in an OME−diesel blend with 5 vol % OME content, show comparable properties to the diesel reference. Based on the findings of this work, it is concluded that engines with NBR or FKM seals should replace their seals with OME resistant seals. In contrast, the long-term storage stability (ASTM D4625-14) of OME has much better properties than diesel fuel. No deposits were detectable after 24 weeks accelerated fuel aging at an ambient temperature of 43 °C.
