“…The results show that PODEn can reduce these emissions significantly. In 2012e2013, Leonardo et al [24,25] studied PODE 3-5 supplied by Ente Nazionale Idrocarburi on diesel engines, and the mass distribution of oligomers in the PODE 3-5 product was the following: 36% However, the injection system exhibits a different dynamic response when fed on pure PODE 3-5 or 50% PODE 3-5 blends. In 2013, 10% and neat PODE 3-5 were tested on a Euro 2 Diesel engine.…”

“…As a new type of oxygenated fuel, polyoxymethylene dimethyl ethers (abbreviated to PODE n ) can effectively reduce emissions of diesel PM as PODE n have no C-C bonds in their molecular structure, have a huge carbon/hydrogen ratio and a high oxygen content with a large cetane number6789. PODE n can be synthesized by polymerization reaction using methanol as a raw material10. There are many crude materials that can be used to produce PODE n , including coal and biomass.…”

This paper focuses on oxidation reactivity and nanostructural characteristics of particulate matter (PM) emitted from diesel engine fuelled with different volume proportions of diesel/polyoxymethylene dimethyl ethers (PODEn) blends (P0, P10 and P20). PM was collected using a metal filter from the exhaust manifold. The collected PM samples were characterized using thermogravimetric analysis (TGA), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Raman spectroscopy. The TGA results indicated that the PM produced by P20 had the highest moisture and volatility contents and the fastest oxidation rate of solid carbon followed by P10 and P0 derived PM. SEM analysis showed that PM generated from P20 was looser with a lower mean value than PM emitted from P10 and P0. Quantitative analysis of high-resolution TEM images presented that fringe length was reduced along with increased separation distance and tortuosity with an increase in PODEn concentration. These trends improved the oxidation reactivity. According to Raman spectroscopy data, the intensity, full width at half-maximum and intensity ratio of the bands also changed demonstrating that PM nanostructure disorder was correlated with a faster oxidation rate. The results show the use of PODEn affects the oxidation reactivity and nanostructure of PM that is easier to oxidize.

“…Regarding diesel blends, it is well‐known that soot formation can be efficiently suppressed by oxygen‐containing components, so‐called oxygenate fuels , . Within an early study, the potential of DMM has been demonstrated and shortly after, results obtained with OME 3,4 as well as OME 3 – 5 mixtures have been reported , . In a systematic study carried out by Härtl et al, the use of different oxygen‐containing compounds has been comprehensively investigated .…”

“…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 .…”

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.
