摘要： An electronic control ignition system, for internal combustion engines, is disclosed in which a rotation angle of a crank shaft of an engine is calculated. The angle is calculated based on a crank angle signal generated every time the crank shaft rotates by a certain angle. Further based on the calculation result, ignition timing is controlled. The control is made to obtain an optimum ignition timing. This optimum ignition timing is based on one train of signals generated every time the crank shaft of the engine rotates by a certain angle, and (n/2-1) (n is an even number equal to or larger than 4) identical train of signals, generated subsequently with a phase delay of 1/n wavelength.

摘要： In an electronic ignition control device which operates based upon a sawtooth shaped crankshaft rotation position signal with conversion of the sawtooth shaped signal into an on/off pulse signal, a ratio of on or off duration of the on/off pulse signal to a cycle time span thereof is used to predict a next top dead center and to determine the ignition timing thereupon.

摘要： An ignition system for an internal combustion engine comprising a semiconductor switching device, which is controlled by a control unit, is disclosed. In response to an output from a device for detecting a shorting breakdown or a heat generation of a power switching device, the power switching device and the ignition coil are cut off from a power supply by a current cut-off device. Even when the power switching device is broken by shorting, the power generation due to continuous energization of the ignition coil is prevented, thereby preventing the ignition coil from being heated abnormally.

摘要： A constant spark rate ignition exciter is disclosed which functions to store a predetermined constant amount of energy in an energy storage element of an ignition system independent of power supply variations. A first embodiment of the invention is a capacitive discharge ignition system. A second embodiment of the invention is an inductive discharge ignition system. Each embodiment produces the constant frequency ignition pulses by the counting of a predetermined count in a counter. The interval during which energy is stored in energy storage elements of the embodiments of the invention is determined by sensing the power supply potential and controlling the time interval for coupling the power supply to the energy storage element in a manner which is inversely proportional to the sensed voltage.

摘要： An ignition system for internal combustion engines is constructed so that, in response to each ignition signal from ignition signal generating means, through a predetermined angle before a succeeding ignition timing, a storage quantity of storing means is gradually increased from an initial value and then it is gradually decreased, and a time point when the storage quantity of the storing means has been decreased to reach the initial value is detected by first storage quantity detecting means to thereby turn on a power transistor for turning on and off a primary current of an ignition coil at that time point, and further the fact that the storage quantity of the storing means has been decreased to reach a set value larger than the initial value is detected by second storage quantity detecting means to thereby change a decrease rate of the storage quantity of the storing means.

摘要： In an ignition control system for the internal combustion engine, a reference angle sensor detects the rotational speed of the internal combustion engine, and detects a point near the top dead center, and generates a reference angle signal. An angle sensor similarly detects the rotational speed of the internal combustion engine, and discriminats the rotational speed for each predetermined angle, and generates an angle signal. A microcomputer includes an output compare register, a free-running counter and a timer control status register, and computes the ignition timing and energization time of the ignition coil in response to a reference angle signal from the reference angle sensor and an angle signal from the angle sensor.

摘要： In an ignition system for an internal combustion engine, a signal generator generates a given ac signal in synchronism with the rotation of the engine and a waveform reshaping circuit reshapes the waveform of the ac signal from the signal generator thus generating a pulse signal. An ignition timing control circuit is responsive to the pulse signal from the waveform reshaping circuit to control the timing of ignition of an ignition coil in which a primary current is switched on and off in accordance with the pulse signal.
