摘要： In an electronically controlled engine supplying fuel from a fuel injector near an intake port to an intake system, asynchronous acceleration fuel injection is carried out in relation to the secondary differential d.sup.2 X/dt.sup.2 of intake pipe pressure or intake air flow rate with respect to time t. Since the d.sup.2 X/dt.sup.2 increases rapidly and accurately after the start of acceleration of the engine, the asynchronous acceleration fuel injection can be carried out rapidly and accurately.

摘要： A method for detecting knock for an internal combustion engine having a plurality of cylinders in which a vibration sensor is attached to each cylinder and a peak value of vibration detected by the sensor is sampled over a predetermined interval near the top dead center. The sampled value is converted from analog to digital and stored for a predetermined number of sampling times to obtain the average value for each cylinder. Then the frequency of occurrences in which the ratio between the sampled peak value and the average value exceeds a reference value is obtained, and the knock is determined when the frequency of occurrences in any one cylinder exceeds a predetermined value or when the average frequency of occurrences of the all cylinders exceed another predetermined value.

摘要： A method and apparatus for performing air/fuel ratio feedback control for an internal combustion engine by comparing the results of the two comparisons; (a) comparing a determined (i.e., decision) value with a measured value detected by an oxygen sensor, and (b) comparing the determined value with a reference value, so as to determine if either is relatively large or small. Further included is an arrangement for determining whether the determined value coincides with the measured value as well as whether it coincides with the reference value, and then increasing or decreasing the determined value in accordance with the result of the determination (comparison), thereby correcting an abnormal condition of the determined (i.e., decision) value whenever the determined value is displaced from a normal condition due to injected random noise.
