    • 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.

    • 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.

    • An AD converter includes a VT converter circuit part which inputs an analog input voltage and a sampling clock, converts the analog input voltage to a corresponding delay time, and outputs time domain data. A ring oscillator circuit part of N stages inputs the time domain data, and an error propagation circuit part takes out delay information containing a quantization error from phase information of the ring oscillator circuit part of the previous stage, and propagate the delay information to the ring oscillator circuit part of a subsequent stage. A counter circuit part measures a number of waves of an output oscillation waveform of the ring oscillator circuit part of each stage, and an output signal generator part generates an output signal from an output counted value of each counter circuit part. A reset part resets each error propagation circuit part and each counter circuit part with a sampling clock.
