Potentials to simplify the engine system using the alternative diesel fuels oxymethylene ether OME1 and OME3−6 on a heavy-duty engine

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

“…Additionally, OMEs are non-toxic and miscible in diesel fuel. 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].…”

Economic and life-cycle assessment of OME3–5 as transport fuel: a comparison of production pathways

“…7 It has been reported that OME can be used directly in conventional compression ignition engines with minor or even no modications. [8][9][10][11] The need for blending OMEs with fossilbased diesel depends on the oligomerization chain length n. OME 1 (n ¼ 1)also known as methylalrequires blending with fossil-based diesel since its vapour pressure and boiling point (42 C) are comparable to those of other gaseous fuels. 6 By contrast, OME 3-5 (3 # n # 5) has a lower vapour pressure and higher boiling point (cf.…”

Comparing pathways for electricity-based production of dimethoxymethane as a sustainable fuel

“…Recently, oxymethylene ethers (OME n , CH 3 O(CH 2 O) n CH 3 ) have received considerable attention as full substitutes [4][5][6] or blend components [7][8][9][10] for diesel fuels. Currently, fossil diesel largely dominates fuel consumption in long-distance and heavyduty transportation and will maintain its crucial role in the next decades, as highlighted by the International Energy Agency.…”

“…8,24 However, engine modifications seem to remain indispensable for both DMM and OME 3-5 . 4,5,25 In addition to the potential direct application in internal combustion engines, DMM is a key intermediate in OME 3-5 production via paraformaldehyde, 26 trioxane, 27,28 or in novel routes via gaseous formaldehyde. 29,30 Commercial DMM production takes place via the condensation reaction of methanol and aqueous formaldehyde (FA).…”
