IPC: F01N13/02
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To carry out suitable purifying treatment by calculating a maximum NOx capacity threshold level as a function of a trap temperature while calculating an accumulating rate of NOx in a trap as a function of engine speed and a load, and starting NOx purifying operation when the accumulating rate of NOx exceeds a threshold level. SOLUTION: In a catalyst converter 26 in which exhaust gas generated in an engine is passed, a catalyst material 28 is stored, exhaust gas is changed chemically so as to generate exhaust gas in which a catalyst is added. Exhaust gas in which the catalyst is added is supplied to a NOx trap 32 arranged on a downstream side, and the NOx is collected. A NOx accumulating rate in the trap 32 is estimated on the basis of an exhaust rate of exhaust gas, speed when exhaust gas is entered into the trap 32 is obtained, and the maximum capacity level of the trap 32 is found out as a function of a temperature of the trap 32. When the accumulating rate of NOx exceeds the maximum capacity level, the mode of an engine is changed from a lean mixture mode into a rich mixture mode so as to purify NOx to be accumulated.
