    摘要: The invention relates to an ignition timing control method and apparatus for an internal combustion engine having a plurality of cylinders. The apparatus includes a knock sensor (401) for detecting a knocking condition in the engine, sensors (40, 50, 60) for detecting other operating conditions of the engine, a microprocessor unit (12) for receiving signals from the sensors (40, 50, 60) to determine a basic ignition timing of the engine and generate an ignition timing control signal, and a power transistor circuit (74) responsive to the ignition timing control signal from the microprocessor unit (12) to switch on and off the primary current in an ignition coil and generate a high-voltage ignition signal. The microprocessor unit (12) has a control function of retarding the basic ignition timing a predetermined amount in response to a knock detected during an ignition operation at the basic ignition timing and another control function of gradually restoring the retarded ignition timing to the basic ignition timing in response to a knock detected during an ignition operation at the retarded ignition timing from the basic ignition timing. The apparatus includes control means (12) responsive to the occurrence of a knock to correct the basic ignition timing for each cylinder of the engine whereby the basic ignition timing of each cylinder is controlled to be retarded in response to the detection of a knock in each cylinder.

    摘要: Accurate detection of abnormal combustion is enabled even in an engine in which a combustion chamber has only one ignition plug provided with an ion-current detection function. An engine control system according to the invention is provided with an ion detector(4) for detecting ions generated during combustion, and a control unit (20) including a combustion-state determination unit for determining on whether the combustion state of the engine is either a normal combustion or an abnormal combustion on the basis of a time-length (Δt) from a fall-time of an ignition-control signal (4h) to a rise-time of an ion-signal (4g) outputted from the ion detector.

    摘要: The invention relates to a method for adjusting adaptive programme maps of an adaptive knock control in an internal combustion engine and to a method for adjusting the knock control. According to said methods, the adaptive programme map (20) is determined by at least one operating parameter (22, 24), whereby the adaptive programme map (20) for each operating parameter range (26) is composed of a precontrol part (bi), which characterizes the environmental conditions, and a remaining part (ai), which results from the knock control. The value of the adaptive programme map for each operating parameter range is determined from the sum of the precontrol part (bi) that corresponds to the respective operating parameter range and the remaining part (ai) that corresponds to the respective operating parameter range. The adaptive programme map is adjusted first by identifying whether a change in the environmental conditions has occurred and subsequently by determining a new precontrol part, in accordance with the changed environmental conditions for each operating parameter range, if the environmental conditions have changed. If the environmental conditions have not changed, the precontrol part for each operating parameter range is held constant.
