Title: Catalyst deterioration detecting device for internal combustion engine
Inventor: NAGAI TOSHINARI
IPC: F02D45/00
Filed: 2003-04-11
Abstract: <P>PROBLEM TO BE SOLVED: To precisely detect catalyst deterioration without deteriorating emission characteristics related to a catalyst deterioration detecting device to detect deterioration of catalyst disposed in an exhaust passage of an internal combustion engine.  <P>SOLUTION: The catalyst to purify exhaust gas is provided in the exhaust passage in the internal combustion engine. Excess or lack in oxygen quantity in exhaust gas flowing inside the catalyst is estimated for each of blocks A-J in a flow direction of the exhaust gas. Based on result of estimation, a convergence point where the excess or lack of oxygen quantity in exhaust gas becomes a determination value or less is specified, and frequency for each block to have the convergence point (stoichiometric convergence point frequency) is counted. The air-fuel ratio is controlled in such a way that the convergent point is positioned on the upstream side of the catalyst. In a case where high convergence point frequency is recognized in a block on the downstream side even after the air-fuel ratio control, it is determined as catalyst deterioration.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
