PROBLEM TO BE SOLVED: The present invention relates to thermal management of an integrated emission reduction system for removing particulate matter (PM) and nitrogen oxides (NOx) from a diesel engine exhaust gas stream. The integrated emission reduction system of the present invention comprises a diesel particulate filter (DPF), a heat source for regulating the temperature of an exhaust gas stream entering the DPF, and at least one selective catalytic reducer for NOx. , A heat exchanger for regulating the temperature of the exhaust gas stream entering the NOx reducer, and for monitoring the temperature and / or pressure of the exhaust gas stream entering the DPF and NOx reducer and the action of the heat exchanger and heat source And a computer for controlling. Thereby, the efficiency of the DPF and the NOx reducer is improved. [Selection] Figure 2 |
