Title: Device and method for controlling air/fuel ratio of internal combustion engine
Inventor: IDE KOJI
IPC: F02D41/14
Filed: 2002-02-15
Abstract: <P>PROBLEM TO BE SOLVED: To prevent ammonia reserved inside a catalyst from being converted to a nitrogen oxide and emitted.  <P>SOLUTION: The device for controlling the air/fuel ratio of the internal combustion engine estimates the absorbed and stored oxygen quantity OSA in the three-way catalyst mounted in an exhaust pathway and controls the air/fuel ratio of the engine so that the estimated absorbed and stored oxygen quantity OSA equals to a target absorbed and stored oxygen quantity OSAref (time t0-t1). When the air/fuel ratio of the engine becomes temporarily richer than a prescribed air/fuel ratio AFR, the control of the air/fuel ratio to make the absorbed and stored oxygen quantity OSA equal to the target absorbed and stored oxygen quantity OSAref is suspended, and the control based on the theoretical air/fuel ratio is executed for a prescribed period of time (time t2-t5). As a result, when ammonia is reserved in the three-way catalyst, the gas with a lean air/fuel ratio including oxygen doesn't flow into the three-way catalyst, and therefore, ammonia isn't converted to the nitrogen oxide and emission of the nitrogen oxide is prevented.  <P>COPYRIGHT: (C)2003,JPO
