Abstract
A control system for an internal combustion engine has a canister for adsorbing evaporative fuel generated in the fuel tank, a purging passage extending between the canister and the intake system of the engine, for purging evaporative fuel into the intake system, and a purge control valve arranged across the purging passage, for controlling the flow rate of evaporative fuel supplied to the intake system through the purging passage. An ECU controls the engine, based on at least one predetermined engine control parameter, and a canister temperature sensor detects the temperature of the canister. The at least one predetermined engine control parameter is changed according to the detected temperature of the canister.
