- Abstract
- Ignition delay times and counterflow diffusion flame products are predicted by blending oxymethylene ether-2 (OME-2) into a surrogate diesel. OME-2 is one of a promising e-diesel blendstock which is synthesized from carbon dioxide and hydrogen, thereby reducing net carbon emission from a carbon life-cycle perspective. Results show that OME-2 is more reactive in engine-relevant conditions and the formation of particulate matter from a diffusion flame could be suppressed, thanks to its higher oxygen content. However, potentially harmful intermediates, e.g., formaldehyde and methyl formate, could be formed in large quantity with the use of OME-2, therefore novel combustion strategy and proper exhaust after-treatment system shall be essential for its practical use.
