Abstract
A control system for an internal combustion engine has a catalyst arranged in the exhaust system, for purifying exhaust gases emitted from the engine. An ECU controls operation of the engine, based on at least one predetermined control parameter, and detects a temperature state of the catalyst at the start of the engine. The at least one predetermined control parameter is changed, based on the detected temperature state of the catalyst, after the start of the engine.
