Abstract
The present invention involves thermal management of an integrated emission reduction system for the removal of particulate matter (PM) and nitrogen oxides (NOx) from diesel engine exhaust streams. The inventive integrated emission reduction system may include a diesel particulate filter (DPF), a heat source for adjusting the temperature of the exhaust stream entering the DPF, at least one selective catalytic reducer of NOx, a heat exchanger for adjusting the temperature of the exhaust stream entering the NOx reducer, and a computing device for monitoring the temperature and/or pressure of the exhaust stream entering the DPF and the NOx reducer, and for controlling the operation of the heat exchanger and heat source, thereby improving the efficiency of the DPF and the NOx reducer.
