An ECU outputs an ignition signal and a discharge waveform control signal. An ignition device closes an ignition switching element in a period during which the ignition signal is input. After a stop of the input of the ignition signal and in a period of input of the discharge waveform control signal, the ignition device controls current flowing through a primary coil to a discharge current command value that is determined by the discharge waveform control signal by opening or closing a control switching element. A discharge control unit determines whether there is an abnormality. When it is determined that there is an abnormality, the ECU avoids control executed by the discharge control unit, and causes the discharge control unit to execute control during times of low-rotation and low-load operation of an internal combustion engine in order to determine whether the discharge control unit has returned to a normal state.

An ECU outputs an ignition signal and a discharge waveform control signal. An ignition device performs a closing operation of an ignition switching device while the ignition signal is input into the ignition device. The ignition device adjusts a current flowing through a primary coil to a discharge current command value determined based on the discharge waveform control signal, by performing an opening-closing operation of a control switching device in a period in which the discharge waveform control signal is input into the ignition device after an input of the ignition signal into the ignition device is stopped. The ECU sets the discharge current command value that is a command value for a discharge current of a spark plug to a higher value as a rotation speed is higher, and prolongs a duration, in which discharge controller controls the discharge current, as the rotation speed is lower.

An ignition system for an internal combustion engine has a power source, a transformer having a first primary winding and a second primary winding and a secondary winding, a connector extending from the secondary winding so as to connect with a terminal of a spark plug, and a multi-strike circuit cooperative with the electronic spark timing circuit so as to fire the transformer with multiple strikes between the falling edge and the rising edge. A booster circuit is cooperative at the electronic spark timing circuit so as to collect and store energy from the power source while the electronic spark timing circuit fires the transformer. A delay circuit fires the transformer at a time subsequent to the falling edge and before the rising edge. 1. An ignition system for an internal combustion engine , the ignition system comprising:a power source;a transformer having a first primary winding and a second primary winding and a secondary winding, said first and second primary windings connected to said power source such that said transformer produces an alternating voltage output from said secondary winding of between 1 kHz and 100 kHz and the voltage of at least 20 kV;a connector extending from said secondary winding, said connector adapted to connect with a terminal of a spark plug of the internal combustion engine;electronic spark timing circuit cooperative with said transformer so as to activate deactivate voltage to said first and second primary windings, said electronic spark timing circuit producing a square wave of voltage in which the square wave has a rising edge and a falling edge, said electronic spark timing circuit firing said transformer at or subsequent to said falling edge and before said rising edge; anda multi-strike circuit cooperative with said electronic spark timing circuit so as to fire said transformer with multiple strikes between said falling edge and said rising edge.2. The ignition system of claim 1 , said multi-strike circuit having an ...

An ignition system and a method for suppressing an ignition spark discharge at a spark gap at an unsuitable time are provided. The method includes a recognition of a spark breakaway and/or a failed ignition and, in response thereto, by producing a conductive path via an ignition spark at the spark gap at a suitable time. 113-. (canceled)14. A method for operating an ignition system for an internal combustion engine , the ignition system including a voltage generator and a spark gap for producing an ignition spark , the method comprising:recognizing at least one of a spark breakaway and a failed ignition; andproducing, in response thereto, a conductive path via an ignition spark at the spark gap in a suitable working stroke of the internal combustion engine or at a suitable ignition time.15. The method of claim 14 , wherein the suitable working stroke includes a working stroke claim 14 , wherein at least one of the following is satisfied:(i) in which at least one of a combustion and an ejection of fluid from a combustion chamber containing the spark gap occurs; and(ii) in which at least one of an intake and a compression occurs, and in which the residual energy stored in at least one electrical energy storage device of the ignition system is below a specified threshold value.16. The method of claim 14 , wherein the production of the conductive path occurs via the ignition spark at the spark gap following each ignition time of an operating state under consideration claim 14 , or of all operating states.17. The method of claim 14 , wherein the recognizing and producing tasks include the following:ascertaining a secondary-side current,ascertaining whether an exceeding condition is met by ascertaining whether a change in the secondary-side current exceeds a specified first threshold value,ascertaining whether an ignition condition is met by ascertaining whether no ignitable mixture is present in a combustion chamber of an internal combustion engine, andproducing a ...
