摘要： In a method for determining an air fuel ratio of an internal combustion engine on the basis of an ion current, for detecting an ion current generated per ignition within a combustion chamber of the internal combustion engine, the method measures a generation period in which the ion current is greater than a determination value set as long as the ion current is generated, computes a divisor for computing a rate of fluctuation of the generation period of the ion current on the basis of a plurality of measured generation periods, computes the rate of fluctuation of the generation period of the ion current by weighing in a direction of increasing the computed divisor, and determines that an air fuel ratio is excessively high in the case that the calculated rate of fluctuation is equal to or more than a predetermined value.

摘要： A diagnosis device for an exhaust gas recycling device diagnoses whether or not an exhaust gas recycling device is operating normally; the temperature of an exhaust gas recycling passage is detected by a temperature detection means, a decision is made by an exhaust gas recycling operating region detection means whether or not the operating region is such as to carry out exhaust gas recycling, when a decision is made that the operating region is such as to carry out exhaust gas recycling a counter is incremented and when otherwise is decremented, and a decision that the exhaust gas recycling is not being carried out normally, that is that the exhaust gas recycling device has failed, is made when the count value of this counter is at least a certain value and the temperature of the exhaust gas recycling passage is not more than a certain value.
