  • Evaporative fuel-purging control system for internal combustion engines
    Patent number: 5299544
    Abstract: An evaporative fuel-purging control system for an internal combustion engine includes at least one flowmeter arranged across a purging passage for outputting a detection parameter indicative of a flow rate of a gaseous mixtured purged through the purging passage, and a purge control valve arranged across the purging passage for controlling the flow rate of the gaseous mixture based on a control parameter indicative of a control amount for the purge control valve. One of the detection parameter and the control parameter is corrected based on a value of the one of the detection parameter and the control parameter assumed when the other of the detection parameter and the control parameter assumes a value corresponding to a state in which the flow rate of the gaseous mixture is equal to the minimum value.
