ABSTRACT:
An evaporative fuel-purging control system for an internal combustion engine comprises a mass flowmeter and a differential pressure type flowmeter arranged in a purging passage of the engine for measuring a flow rate of a mixture of evaporative fuel and air being purged. The flowmeters have different output characteristics relative to change in the concentration of evaporative fuel in the mixture from each other. Output values from the flowmeters are compared to obtain a difference or a ratio therebetween. Failure of at least one of the flowmeters is detected based upon the difference or the ratio.
