Abstract
A compression ignition internal combustion engine system combusts DME as fuel using high fuel injection pressures (e.g., above 800 bar) and low oxygen concentrations (e.g., below 17%, through high levels of EGR), thereby resulting in simultaneously very low NOx and PM engine-out emissions.
