Title: Exhaust emission control device of internal combustion engine
Inventor: NIIZAWA MOTOHIRO
IPC: F01N3/18
Filed: 2000-09-14
Abstract: PROBLEM TO BE SOLVED: To ensure continuous recombustion of a particulate filter using NO2, by controlling a temperature of an oxidizing catalyst to the temperature at which conversion from NO to NO2 is actively performed. SOLUTION: An oxidizing catalyst is placed upstream of the particulate filter for collecting exhaust fine particles, NO in an exhaust air is converted to NO2 so that the exhaust fine particles are continuously burnt again with this NO2. Conversion to NO2 by the oxidizing catalyst is active at a temperature of the catalyst of 250 to 450 deg.C. At the temperature of 600 deg. or more, the exhaust fine particles can be burnt by O2. Thus, when recycling is required, in the range a and b at the exhaust temperature of 200 to 250 deg.C, the temperature of the oxidizing catalyst is raised by post ignition, and in the range of d to f at the exhaust temperature of 450 to 600 deg.C, the temperature is lowered by introducing air.
