Exhaust emission reduction system includes particulate filter within exhaust stream, heat exchanger to adjust temperature of diesel exhaust stream and catalytic absorber of nitrogen oxides within temperature adjusted diesel exhaust stream
Exhaust emission reduction system includes particulate filter within exhaust stream, heat exchanger to adjust temperature of diesel exhaust stream and catalytic absorber of nitrogen oxides within temperature adjusted diesel exhaust stream
An exhaust emission reduction system includes a diesel particulate filter (DPF) (20) contained within the exhaust stream, a heat exchanger (40) to adjust the temperature of the diesel exhaust stream; at least one catalytic absorber (60) of nitrogen oxides (NOx) within the temperature adjusted diesel exhaust stream; a heat source (30) capable of heating the exhaust stream and a computing device. The computing device monitors the temperature of the exhaust stream entering the DPF and the NOx absorber. Independent claims are included for the following: (a) controlling the exhaust emission reduction system for reducing exhaust stream emissions produced by a diesel engine; and (b) a computing device for controlling the system for reducing exhaust stream emissions produced by the diesel engine.
