摘要： An ignition timing control system for an engine provides a counter-measure for an abnormal condition of a signal. The ignition timing control system has a first signal generator for generating a first signal at intervals of a predetermined crank angle while an engine is rotated n times (n is an arbitrary positive number), this first signal including a marked signal designating a particular cylinder each time the engine is rotated n times; a second signal generator for generating a second signal having pulses in a number equal to that of all cylinders of the engine at intervals of substantially an equal crank angle in synchronism with the first signal, this second signal including a signal of a form which is distinguishable from other second signal and which occurs in synchronism with the marked signal; a unit for producing an ignition signal in response to the first signal; a distributor for receiving the ignition signal and distributing the ignition signal in response to the marked signal of the first signal to each cylinder in a predetermined ignition order; a unit for detecting an abnormal condition of the first signal; and a unit for distributing the ignition signal to each cylinder in a predetermined ignition order in response to the signal synchronized with the marked signal of the second signal in place of the marked signal when the abnormal condition of the first signal is detected.

摘要： A method and apparatus is disclosed for controlling the duration of ionization of spark plugs in an internal combustion engine. Generally, the ionization times of the spark plugs are individually measured and compared against a reference ionization time to develop an error signal representing an undesired deviation from the reference ionization time. Then, the duration of current dwell time in the engine's ignition coil is adjusted so as to change ionization time and reduce the size of the error signal.

摘要： An ignition system for an internal combustion engine is widely known which includes a primary current control switch circuit adapted to be turned off at an ignition position to interrupt flowing of a primary current through an ignition coil, to thereby induce a high voltage for ignition across the ignition coil. Continuation of the flow of the primary current causes an increase in power consumption and generation of heat from the ignition coil. An ignition system of the present invention utilizes charging and discharging of a control capacitor to permit control over the time for which the primary current is flowing to be accomplished with a simple structure. A discharge resistor which is arranged in parallel with the control capacitor carries out discharge of the control capacitor to interrupt the flow of the primary current when the internal combustion engine is stopped.

摘要： The circuit according to the invention comprises a hysteresis comparator 9 connected to a transistor 2 controlling the current flowing in an inductive load 1. The voltage taken across the terminals of a measurement resistor 3 is compared with a reference voltage established by a source 6. According to the invention, a feedback loop 10 establishes a proportional action of the transistor 2 on the current in the load 1 when the voltage at S exceeds a predetermined threshold. In this way an oscillation is obtained between two values on either side of a nominal value, these two values being associated with the thresholds of the hysteresis comparator. Application to the production of an integrated circuit for the control of the ignition coil of an internal combustion engine.

摘要： An ignition signal distributing circuit for a multicyclinder engine in accordance with the present invention comprises a delay circuit which delays an output signal of a crank angle sensor or a cranking switch signal for the duration until the first output signal of the crank angle sensor is completed in the early stage of the time immediately after a starting of power supplying, and thereby an output of an error ignition signal can be prevented which is caused by that the crank angle sensor outputs a detection signal when power supplying is started.

摘要： An ignition system for at least one spark plug of an internal combustion engine includes an ignition coil having a secondary winding connected to the plug, a control commutator device controlling the flow of current in the primary winding of the ignition coil, a device for monitoring the intensity of the current flowing in the primary winding and electrical sensors which provide signals indicative of the operating conditions of the engine. A control unit is provided with memory devices in which are stored data indicative of predetermined final values for the current in the primary winding of the ignition coil associated with various operating conditions of the engine. The control unit is also arranged to pilot the commutator device so that each time a spark needs to be generated the flow of current in the primary winding of the ignition coil is stopped when the magnitude of current has reached the final value which is associated in the memory device with the prevailing operating conditions of the engine.

摘要： In an electronic ignition apparatus, there are provided an ignition signal generator, an ignition circuit, an ignition-noise masking signal generator, a switching transistor and an ignition coil. The ignition signal of the ignition signal generator is supplied to the ignition circuit to produce a first ignition pulse and a second ignition pulse which is electrically isolated from the first ignition pulse. The first ignition pulse is applied to the switching transistor so as to switch the collector voltage thereof, whereby high voltage ignition pulse is produced in the ignition coil. The second ignition pulse is applied to the ignition-noise masking signal generator to produce an ignition-noise masking signal. The ignition-noise masking signal is superimposed on the ignition signal so as to mask the ignition noise at least when the high voltage ignition pulse is produced in the ignition coil.

摘要： In an ignition system for an internal combustion engine, on-off signals each responsive to one of a plurality of ignition signals from an engine control unit to switch on and off the primary current in an ignition coil are detected. A first trigger signal is produced from the logical sum of the detection signals and a second trigger signal is produced from the logical sum of the plurality of ignition signals from the engine control unit. A single nonretriggerable monostable multivibrator receives the first and second trigger signals to generate an engine ignition monitor signal.
