摘要： In order to solve a problem that in an internal combustion engine in which abnormal combustion (knocking or an accidental fire) of an engine is detected from an ion signal, the setting of an abnormal combustion determination threshold value under a transient condition in which an engine operating state abruptly changes is difficult to thereby cause erroneous determination, the present invention is an engine control device provided with an ion signal detection means for detecting ions generated during combustion, and provided with an abnormal combustion determination means for determining knocking or an accidental fire according to an ion signal detected by the detection means, the engine control device being characterized by being provided with an in-cylinder temperature estimation means for estimating the in-cylinder temperature in a normal combustion cycle under a current operating condition of the engine, and by setting the knocking determination threshold value or accidental fire determination threshold value of the ion signal on the basis of the estimated in-cylinder temperature information. Consequently, it becomes possible to accurately detect abnormal combustion even under a transient operating condition.

摘要： A detection section includes first and second conductors embedded in a ceramic substrate and is attached such that the substrate is exposed to a space in which ions are generated as a result of combustion of fuel. A measurement section measures the value of current flowing through the second conductor as an ion current originating from the generated ions. A correction section or a control section is provided to mitigate the influence, on the accuracy in detecting an ion current value, of a change in the temperature of the detection section. The correction section corrects the current value measured by the measurement section on the basis of the electrical resistance of the substrate between the first conductor and the second conductor. The control section controls the supply of electricity to the first conductor such that the electrical resistance becomes equal to a predetermined value. In the case where the control section is provided, the measurement section measures the current value in a state in which the supply of electricity to the first conductor is controlled by the control section.

摘要： A method of controlling the spark lead of an internal combustion engine having at least one cylinder fitted with a spark plug; the method including the steps of: determining a standard spark lead value; determining an engine knock index in the cylinder; calculating a correction factor as a function of the engine knock index; determining a modified spark lead value by applying the correction factor to the standard spark lead value; and controlling the spark plug using the modified spark lead value. The correction factor is calculated by statistically analyzing a number of engine knock indexes to calculate a cumulative distribution; comparing the cumulative distribution with at least one target value; and modifying the current correction factor value as a function of the comparison between the cumulative distribution and the target value.

摘要： An object is to mitigate the influence, on the accuracy in detecting an ion current value, of a change in the temperature of a detection section which detects the ion current value.
A detection section includes first and second conductors and a substrate and is attached such that the substrate is exposed to a space in which ions are generated as a result of combustion of fuel. The substrate is formed of ceramic, and the first and second conductors are separately embedded and held in the substrate. A measurement section measures the value of current flowing through the second conductor as an ion current originating from the generated ions. An obtainment section obtains the electrical resistance of the substrate between the first conductor and the second conductor. The problem is solved by providing a correction section or a control section. The correction section corrects the current value measured by the measurement section on the basis of the electrical resistance obtained by the obtainment section. The control section controls the supply of electricity to the first conductor such that the electrical resistance obtained by the obtainment section becomes equal to a predetermined value. In the case where the control section is provided, the measurement section measures the current value in a state in which the supply of electricity to the first conductor is controlled by the control section.
