Abstract
A NOx control system includes a lean NOx catalyst and an alcohol generator. The lean NOx catalyst includes a substrate and a hydrocarbon selective catalytic reduction (HC-SCR) catalyst disposed on the substrate. The HC-SCR catalyst catalyzes a reduction of NOx with an alcohol. The alcohol generator generates the alcohol.
