摘要： 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.

摘要： There is provided a control system for an internal combustion engine, which is capable of properly controlling the amount of exhaust gas recirculation according to a degree of flow rate degradation of an exhaust gas recirculation system and at the same time suppressing progress of the flow rate degradation. The control system has an exhaust gas recirculation system including an exhaust gas recirculation passage for communicating between an exhaust passage and an intake passage, and an exhaust gas recirculation valve for controlling the rate of exhaust gas recirculation to the intake passage via the exhaust gas recirculation passage according to the operation amount of the valve. An ECU cuts off supply of fuel to the engine during deceleration of the engine. An intake pipe absolute pressure sensor detects pressure within the intake passage. Further, the ECU sets an upper limit of the operation amount of the exhaust gas recirculation valve according to a change in the pressure within the intake passage detected when the exhaust gas recirculation valve is opened and closed during the cut-off of fuel supply.

摘要： A control system for controlling an internal combustion engine having an exhaust gas recirculation mechanism consisting of an exhaust gas recirculation passage connected between the exhaust passage and the intake passage of the engine, and an exhaust gas recirculation valve provided in the recirculation passage for controlling an exhaust gas amount to be recirculated. Control parameter(s) of the engine are calculated according to operating conditions of the engine. An amount of change in the intake pressure between when opening the exhaust gas recirculation valve and when closing the exhaust gas recirculation valve, in the fuel-cut operation, is calculated. The abnormality of the exhaust gas recirculation mechanism is determined according to the amount of change in the intake pressure. The engine is controlled by using the control parameter suitable for a closed condition of the exhaust gas recirculation valve during a predetermined time period.
