Numerical analysis of the combustion process of oxymethylene ethers as low-carbon fuels for compression ignition engines

To ensure a future for this technology, Mitigation of the carbon footprint of internal combustion engines is essential. E-fuels are regarded as a potential alternative to replacing conventional fossil fuels within this framework. For this reason, this paper is focused on the synthesis of oxymethylene ethers as a potential low-carbon fuel substitute. When replacing fossil Diesel in internal combustion engines under similar operating conditions, the aim is to increase the understanding of the combustion process of these e-fuels. A numerical fluid dynamics simulation of an optical compression ignition engine has been created to achieve this goal. While OME X was simulated as a simpler mixture of oxymethylene ether molecules, n-Heptane was used as a surrogate of fossil Diesel. The results reveal striking differences between Diesel and OME X. Consequently, oxidation reactions are favored in wider areas inside the combustion chamber, contributing to a quicker combustion process.
