Observation of OME-diesel blends spray injected by a single-hole nozzle injector under engine-relevant conditions

Nihon Kikai Gakkai ronbunshu, 2021
The fuel generated from CO2 and H2 derived from renewable energy is called “e-fuel”. Among the e-fuels, polyoxymethylene dimethyl ether (OME) is expected as a promising drop-in fuel for CI engines because it has good ignitability and low-soot combustion ...
