“…Regarding the combustion behavior of pure OMEs, OME mixtures such as OME 3 – 5 as well as pure OMEs with uniform chain length have been investigated , . By excluding conventional diesel fuel, formation of particulate matter and NO x can be suppressed almost completely which enables to overcome the soot‐NO x trade‐off . The use of pure OMEs is currently compared to the use of OME‐diesel blends.…”

To counteract greenhouse gas and other harmful emissions, ambitious regulatory measures with respect to energy generation, supply and consumption have been set. In the fuel sector, successive substitution of common fossil fuels by non‐fossil ones is a promising option to meet the respective demands. Regarding diesel fuels, the use of oxymethylene ethers (OMEs) has been proposed. Especially OMEs of the type CH3O(CH2O)nCH3 (n = 3 – 5) exhibit properties that are similar to common diesel fuel and formation of soot and NOx is drastically reduced during combustion. Within this work, recent progress regarding production, application and evaluation of OMEs is summarized and discussed.

“…Oxymethylene ethers (OME n , CH 3 (OCH 2 ) n OCH 3 ) can be used as diesel fuels. These oligomeric compounds show advantageous combustion properties and contribute to the solution of the soot-NO x trade-off [14,52,53]. The addition of OMEs to gasoline has not been investigated yet.…”

“…Oxymethylene ethers (OME n , CH 3 (OCH 2 ) n OCH 3 ) [12,13] are currently investigated to optimise PM emission behaviour of diesel combustion. Several studies [14,15,16,17] have demonstrated significant reductions of PM emissions by admixture of OME1, which can be attributed to its high oxygen content (42.1 wt.-% [12]) and non-existent C-C bonds (acetylene hypothesis [18]).…”

Bio-fuels of the 2nd generation constitute a key approach to tackle both Greenhouse Gas (GHG) and air quality challenges associated with combustion emissions of the transport sector. Since these fuels are obtained of residual materials of the agricultural industry, well-to-tank CO 2 emissions can be significantly lowered by a closed-cycle of formation and absorption of CO 2. Furthermore, studies of bio-fuels have shown reduced formation of particulate matter on account of the fuels' high oxygen content therefore addressing air quality issues. However, due to the high oxygen content and other physical parameters these fuels are expected to exhibit different ignition behaviour. Moreover, the question is whether there is a positive superimposition of the fuels ignition behaviour with the benefits of an alternative ignition system, such as a corona ignition. To shed light on these questions two oxygenic compounds, oxymethylene ether-1 (OME1) and dimethyl carbonate (DMC) have been studied with respect to OH* emission throughout ignition and onset of flame-front propagation in a combustion chamber with a large optical access via a quartz window. OH* measurements have been recorded via a high-speed optical camera (5 kHz) coupled with 308 nm optical filter and image intensifier. Sealing material swelling tests have yielded a perfluoroelastomer (FFKM 72) as an ideal, cost-efficient material regardless of the applied fuel. Comparative measurements with both ignition systems for combustion of gasoline as well as moderate blend admixtures of OME1 and DMC have demonstrated the superior ignition stability with likewise implications on flame-kernel development for the corona ignition. Furthermore a strong influence of the mode of discharge on OH* formation rates was observed especially for the oxygenic blends. Finally, for admixture variations of both oxygenates, an increased OH* level was shown during discharge thereby proving the hypothesis of a positive superimposition of oxygenic fuel and corona ignition system.

“…This also enables the use of existing infrastructure for the transportation, storage, and distribution of OME blends with diesel. [6][7][8][9] The well-to-wheel (WtW) CO 2 emissions can be signicantly reduced compared to fossil-based fuels if OME are produced from renewable carbon sources and low-carbon H 2 . 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.…”
