Title: Device for controlling exhaust gas for internal combustion engine
Inventor: IKEMOTO NOBUAKI
IPC: F01N13/02
Filed: 2002-02-25
Abstract: <P>PROBLEM TO BE SOLVED: To quickly consume oxygen stored in catalyst and to reduce emission discharged to the air even if estimated value of oxygen storing quantity is shifted.  <P>SOLUTION: When fuel cut is executed on timing T2, oxygen storing quantity SMO2 stored in the catalyst is calculated. A target air fuel ratio λTG is set to 0.990 at recovery from fuel cut on timing T4. When it is detected based on output VOX2 of an oxygen sensor that oxygen in an upstream side catalyst is consumed, the target air fuel ratio λTG is switched to 0.995. When oxygen storing quantity SMO2 get 0 at the end, normal feed back control is recovered. Consequently, oxygen stored in a catalytic converter is consumed quickly and emission discharged in the air is reduced even if the estimation value of oxygen storing quantity is shifted by switching the target air fuel ratio λTG like this.  <P>COPYRIGHT: (C)2003,JPO
