摘要： A magnetic detector to detect a magnetic object's rotation and movement using a magnetoresistive element having hysteresis. The magnetoresistive element is set so as to tilt from the magnetizing direction of a magnet up to a predetermined angle &thgr; between the rotational magnetic object to be detected and the magnet. The magnetic detector provides a high accuracy signal that corresponds to the distance between the rotational magnetic object to be detected and the magnetoresistive element. The signal obtained is independent of the rotational direction or rotational speed of the magnetic object to be detected or the atmospheric temperature of an apparatus. Moreover, the temperature dependency of the output signal (amplitude) of the magnetoresistive element is decreased.

摘要： An ignition controller for an internal combustion engine includes a control/calculation circuit for creating drive signals to injectors and ignition coils based on the rotation angle SGT and the operating state of the internal combustion engine. The control/calculation circuit includes means for calculating the respective timings at which the injectors and the ignition coils are controlled according to an operating state, means for discriminating a predetermined operating state corresponding to a state where fuel adheres to the ignition plugs and means for switching the timings at which the ignition plugs are driven according to a signal which discriminates the predetermined operating state. When the predetermined operating state is not discriminated, the timings at which the ignition coils are driven are set to the vicinity of the upper dead point of a compression stroke and when the predetermined operating state is discriminated, the above timings are set to the respective vicinities of the upper dead point of the compression stroke and the upper dead point of an exhaust stroke. With this arrangement, the ignition controller for the internal combustion engine can always maintain a stable combustion state by avoiding the adhesion of fuel to the ignition plugs.

摘要： Misfiring in a cylinder of an engine can be detected with high reliability using a statistical treatment even if the level of ion current generated by a spark plug upon ignition thereof is affected by noise. An ion current, which is generated when a spark plug for a cylinder discharges, is detected to provide a corresponding voltage which is then integrated or peak held to produce a current component signal which is generated for a predetermined time from the time of discharge of the spark plug. The current component signal is used as misfiring information and compared with a prescribed threshold so as to determine whether there is misfiring in the cylinder. Misfirings thus detected are counted so as to evaluate the state or extent of misfiring in the cylinder. If the state of misfiring is serious, the fuel supply to the cylinder is stopped. If, however, it is light, an appropriate measure for optimizing the operation of the misfiring cylinder is taken to remedy such a situation and recover normal combustion therein.
