Abstract
An evaporative fuel-purging control system for an internal combustion engine includes a mass flowmeter arranged across a purging passage of the engine for measuring a flow rate of a mixture of evaporative fuel and air being purged. A desired flow rate of the mixture is set according to operating conditions of the engine. The desired flow rate of the mixture is compared with a measured flow rate of the mixture obtained by the mass flowmeter, and the opening of a purge control valve arranged across the purging passage is controlled based on results of the comparison.
