Abstract
An apparatus for predicting and discriminating whether or not misfire, knocking and the like will occur from the cylinder pressure before the occurrence of the misfire, the knocking and the like by the use of a three layered neural network. The cylinder pressure signal detected by a cylinder pressure sensor is sampled and input to each of the elements of the input layer. The signal then is modulated corresponding to the strength (weight) of the connection between each of the elements, and transmitted to the hidden and output layers. The magnitude of signal from the elements of the output layer represents the prediction and discrimination results. The weight is learned and determined by a back propagation method.
