Abstract: An ECU determines whether or not an engine water temperature has exceeded a predetermined value; and actively opens and closes a wastegate valve, and calculates a shift in a learning value amount. The ECU determines whether or not the learning value shift amount is sufficiently large to surpass a predetermined value and when the determination result is Yes (when the condition is fulfilled), takes in the learning value shift. The ECU determines whether or not the engine water temperature is sufficiently low to be below a predetermined value and reflects the learning value shift in the air-fuel ratio learning value.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: An apparatus and method for controlling an internal combustion engine can perform exact timing control for ignition timing, fuel injection timing and the like in an inexpensive manner. A crank angle sensing means 20 generates a crank angle signal .theta. comprising a series of successive pulses in synchronization with the rotation of the engine. A cylinder pressure sensor 21 senses an internal pressure in at least one of cylinders of the engine and generates a corresponding cylinder pressure signal P. A pressure peak detecting means 42 detects a peak in the internal pressure in the at least one cylinder during an engine cranking cycle. A reference position setter 43 sets as a reference position the crank angle signal at the instant when the pressure peak in the at least one cylinder is detected. A control timing setter 44 includes a position counter for counting the number of pulses in the crank angle signal. The counter is reset in response to an occurrence to the reference position. The control timing setter is operable to set a control time Ta corresponding to a control timing for each of the cylinders on the basis of a counted value of the counter. With this arrangement, the crank angle sensing means 20 generates no reference signal and hence can be simplified.

Abstract: An engine control apparatus and method for accurately controlling the operation of an engine such as ignition, fuel injection, etc., particularly in the high-speed range or during a sudden change in the rotational speed of the engine. A signal generator generates a positional signal in the form of pulses representative of a reference piston position of each cylinder in synchrony with the rotation of the engine. A sensor means senses the operating conditions of the engine. A control unit in the form of a microcomputer, which includes a timer means for controlling the operations of the corresponding cylinders, calculates, based on the positional signal and the output signal of the sensor means, control times for controlling the corresponding cylinders at every reference piston position, and determine, at every reference piston position, whether the timer means has already done control on the cylinders. If the timer means has yet to do control on the cylinders, the control unit resets or updates the dimer means to new control times which are calculated at the present reference piston position for controlling the present operations of the cylinders. On the other hand, if the timer means has already done control on the cylinders, the control unit sets the timer means to new control times which are calculated at the present reference piston position for controlling the next operations of the cylinders.
