Title: Catalyst deterioration detection device for internal combustion engine
Inventor: MITSUYA NORITAKE
IPC: F02D45/00
Filed: 2002-05-23
Abstract: PROBLEM TO BE SOLVED: To prevent erroneous decision accompanying counter control and decide deterioration of a catalyst by a catalyst downstream O2 sensor, in a system for constantly controlling an O2 storage amount using an A/F sensor. SOLUTION: When deciding the deterioration of a three-way catalyst on the basis of a track length of an output of the O2 sensor within a period during air-fuel ratio feedback control, calculation of the locus length is interrupted for a period wherein an output VAF of the A/F sensor is out of a prescribed range, and for a prescribed period after the output VAF of the air-fuel ratio sensor becomes a value within the prescribed range thereafter. Alternatively, an upper limit value is set to an integration term gain or an absolute value of an integration term in PI control during catalyst deterioration decision processing.

The exhaust gas containing the NO<SB>2</SB>components is converted into gas extensively reduced in NO<SB>2</SB>components by an NO<SB>2</SB>decomposing reaction by catalytic action of Al<SB>2</SB>O<SB>3</SB>composing a catalyst bed 3 when passing the catalyst bed 3. The exhaust gas coming out from the catalyst bed 3 rises in an exhaust gas passage and it is lead to a sub heat exchanger 10. The exhaust gas gives heat to tap water supplied via a water supply pipe 6, and it itself is cooled further. In the sub heat exchanger 10, a temperature of the exhaust gas becomes a dew point or lower, and condensed water forms on a sub heat exchanger 10 surface. The formed condensed water drips into a condensed water recovering tray 17, and it is drained outside through a drain pipe 12. In such a case, since NO<SB>2</SB>components in the exhaust gas are already extensively reduced by the catalyst bed 3, pH reduction of the condensed water due to dissolution of NO<SB>2</SB>is an ignorable degree.  <P>COPYRIGHT: (C)2004,JPO
