Abstract
The selective catalytic reduction of nitrogen oxides (especially NO and NO) in exhaust from diesel and other lean burn engines is improved by use of a compact hyperplasma reactor for generating ozone and other highly oxidizing species in a stream of air. A portion of the ozone containing air stream is blown directly into the exhaust for oxidizing NO to NO. The other portion of plasma treated air is used to fractionate and reform a volume of diesel fuel to produce low molecular weight hydrocarbons and oxidized hydrocarbons to be added to the exhaust as NOreductants in the catalytic reduction.
