Title: Exhaust emission control device for internal combustion engine
Inventor: GOTO MASAHITO
IPC: B01D53/94
Filed: 1997-04-03
Abstract: PROBLEM TO BE SOLVED: To avoid NOx emission from NOx absorbent during stopping of an engine. SOLUTION: NOx absorbent 18 is arranged in an exhaust pipe 17 in an internal combustion engine 1, and a controlling circuit 30 which controls the amount of injected fuel in the engine 1 is provided. The control circuit 30 operates the engine 1 at lean air-fuel ratio, and estimates amount of NOx absorbed by the NOx absorbent 18, and when the amount of absorbed NOx reaches a specified value, operates the engine 1 at rich air-fuel ratio, emits NOx from the NOx absorbent, and reduces and purifies it. When an enginestop operation is done, the control circuit 30 does not stop the engine immediately after the stopping operation, and stops the engine after a specific period operation at rich airfuel ratio. Thus, NOx is emitted from the NOx absorbent and it is reduced and purified.  Because NOx is not kept in the NOx absorbent during stopping of the engine, decrease of the NOx absorbent temperature after stopping of the engine is prevented from causing emission of non-purified NOx from the NOx absorbent.
