Abstract:
A system ( 9 ) of the invention is a system for detecting deterioration of a catalyst ( 8 ) provided in an exhaust passage ( 12 ) of an internal combustion engine ( 11 ), the system including: means ( 5 ) that detects a temperature of an exhaust on an upstream side of the catalyst ( 8 ); means ( 6 ) that detects a temperature of the exhaust on a downstream side of the catalyst ( 8 ); a recognition unit ( 10 ) that recognizes, both upstream and downstream of the catalyst ( 8 ), a change point at which the temperature changes from temperature fall or constant temperature to temperature rise during acceleration operation, or a change point at which the temperature changes from temperature rise or constant temperature to temperature fall during deceleration operation; and a determination unit ( 10 ) that determines that the catalyst ( 8 ) has deteriorated when a difference (ΔT or ΔT′) between the upstream and downstream change points becomes equal to or longer than a predetermined time.

Claim (Index 3):
The catalyst deterioration detecting system according to  claim 1 , wherein the upstream-side temperature detection means and the downstream-side temperature detection means respectively have different time constants.
