Title: Deterioration detecting method of exhaust emission control catalyst
Inventor: KATO NOBUHIDE
IPC: F01N13/02
Filed: 1995-12-15
Abstract: PROBLEM TO BE SOLVED: To detect deterioration of a catalyst with good accuracy without carrying out constant speed running for a long time by detecting reduction of a heat quantity generated from exhaust gas a unit quantity of exhaust gas in a unit time by reaction accelerated by the catalyst. SOLUTION: Since reaction for oxidizing combustible component by an exhaust emission control catalyst is a heating reaction, reaction is not accelerated efficiently in the case where a catalyst is deteriorated, and a generating heat quantity Eg is reduced. The reduction of the generation heat quantity Eg caused by deterioration appears more notably comparing with the case of high temperature, the lower the temperature of the catalyst is. Reduction of a cumulative value in the temperature range, in the heat quantity Eg generated from exhaust gas having the unit quantity in the unit time by reaction accelerated by the catalyst is detected in a proper temperature partition composing of a temperature range, while the temperature of the catalyst is raised in a prescribed range after an engine is started.  It is thus possible to detect deterioration of the catalyst with good accuracy rapidly and easily without carrying out constant running for a long time.
