    摘要: A method and apparatus are provided for synchronizing an event of an internal combustion engine at least in part as a function of the load on the engine. Desirably, the ignition timing of the engine may be controlled as a function of the load on the engine. Preferably, the system and apparatus utilize existing engine sensors to provide the information needed to determine the load on the engine. Also preferably, the system and apparatus provide the load determination to other systems such as a fuel injection system to improve the timing of the injection event of the system.

    摘要: An ignition timing control device for an internal combustion engine is capable of preventing shock of an engine upon rapid acceleration by suitably controlling the ignition timing of the engine. When the width of the opening of a throttle valve is kept within a specific width for a first specific time or more in a state where the opening of the throttle valve is smaller than a specific low opening and immediately after, the opening of the throttle valve is increased from the specific low opening to more than a specific high opening for a second specific time or less, it is decided that the internal combustion engine is in a rapid acceleration state. Ignition timing of the engine is therefore retarded.

    摘要: The invention relates to an ignition system for a 14 V or 42 V on-board power system voltage which is connected to the ignition transformer directly via the semiconductor power output stage without an intermediate power unit. After an input signal from a superordinate engine control device, the semiconductor power output stage is switched on by an ignition control device. As a result, a current is built up at the primary side of the ignition transformer. After the predefined maximum current value is reached for the first time, the primary side of the ignition transformer is switched off for a predefined time period. In this time period, a maximum voltage for the spark breakdown is built up at the electrodes of the spark plug according to the principle of self induction. After the spark discharge, the primary side of the ignition transformer is timed and current-limited until the end of the ignition process which is predefined by the superordinate engine control device. The timed control operates with selected, predefined time intervals for switching the semiconductor power output stage alternately on and off. A current limitation is superimposed on the timed control and switches off the primary side of the ignition transformer whenever the primary current reaches a predefined maximum value.

    摘要: A circuit to achieve a large ignition advance, limitation of speed of revolutions and to prevent backfiring and reverse direction running in a magnetic ignition system that comprises a flywheel with two poles and a two-legged iron core. An ignition transformer (L3/L4), a charging coil (L1) and a triggering coil (L2) that may be connected in antiphase to the charging coil are arranged on the first leg in the direction of rotation of the flywheel. A time-constant circuit (an RC net) and a control switch (T2) are arranged between the charging coil and a main switch (T1) that open/block triggering pulses such that charging takes place one revolution later than triggering. Limitation of the speed of revolutions is achieved with a time constant that can be determined.

    摘要: A method is provided for igniting a fuel/air mixture within a preselected time after the fuel/air mixture has been injected into the combustion chamber of a cylinder. In this way, the ignition event occurs while the fuel/air mixture is stratified and before it has an opportunity to mix within the cylinder and become homogenous. By assuring that the fuel/air mixture is stratified, the wetting of cylinder walls is significantly decreased and the variability of conditions within the combustion chamber are reduced.

    摘要: In an automotive engine control apparatus used for a multi-cylinder engine where both an injection coil and an ignition coil are employed with each of multiple cylinders, abnormal states are systematically detected, while an injection system is mutually interconnected with an ignition system as to these abnormal states. The injection coils are driven via a first switch element by a microprocessor, and injection operations of these injection coils are monitored by a first detection circuit. The ignition primary coils are driven via a second switch element by the microprocessor, and ignition operations of these ignition coils are monitored by a second detection circuit. The microprocessor controls drive stopping means to perform a turn-out drive operation such that this drive stopping means stops both a fuel injection operation and an ignition operation of an abnormal-operated cylinder with respect to an abnormal state occurred in either the injection system or the ignition system. Also, abnormal-state storage operation by abnormal state storage means separatedly provided for the injection system/ignition system/cylinder system, which is derived from stopping of the drive operations, is prohibited by storage prohibiting means.

    摘要: An ignition timing control system for an internal combustion engine includes an electronic control unit. In a transition state where an in-cylinder EGR rate varies, the unit calculates an ignition timing corresponding to the in-cylinder EGR rate by means of linear interpolation based on ignition timings for EGR and non-EGR operations determined from maps, sets a retard amount based on the ratio of the in-cylinder EGR rate to a target EGR rate, and performs ignition timing control based on a corrected ignition timing obtained by subtracting the retard amount from the calculated ignition timing, thus preventing occurrences of knocking due to excessively advanced ignition timing, and deteriorated fuel consumption and drivability.
