Stripping ethanol from ethanol-blended fuels for use in NO

x A method to use diesel fuel alchohol micro emulsions (E-diesel) to provide a source of reductant to lower NOemissions using selective catalytic reduction. Ethanol is stripped from the micro emulsion and entered into the exhaust gasses upstream of the reducing catalyst. The method allows diesel (an...

Summary:x A method to use diesel fuel alchohol micro emulsions (E-diesel) to provide a source of reductant to lower NOemissions using selective catalytic reduction. Ethanol is stripped from the micro emulsion and entered into the exhaust gasses upstream of the reducing catalyst. The method allows diesel (and other lean-burn) engines to meet new, lower emission standards without having to carry separate fuel and reductant tanks.
