Abstract: When an abnormality judgement section judges that there is a failure of an energy inputting circuit, an energy inputting line, through which electrical energy is inputted from the energy inputting circuit to a primary winding, is changed over to a disconnected state by output halt switching means. As a result, since inputting of electrical energy to the primary winding is thereby halted, problems arising due to continuation of inputting electrical energy to the energy inputting circuit can be prevented, even in the event of a failure of the energy inputting circuit, so that reliability can be enhanced.

Abstract: An ignition device for engine according to the present invention performs continuous spark discharge of an ignition plug by using a multiplex signal, an integration signal or a control signal. In the multiplex signal, discharge continuous signals IGW#1 to 4 for cylinders of the engine have been multiplexed. In the integration signal, a discharge continuous signal IGW and a secondary current instruction signal IGA have been added to an ignition signal IGT. In the control signal, the secondary current instruction signal IGA has been added into the multiplex signal or the integration signal. This structure can reduce the total number of signal lines connected between an ECU and a controller, and further reduce a signal line to transmit the secondary current instruction signal IGA.

Abstract: A battery, an energy charge inductance, and a first transistor are connected in series in an ignition system. A primary winding and a second switching device are connected in series between the ground and a point between the energy charge inductance and the first switching device. A drive circuit switches periodically on and of f the first switching device and the second switching device during multispark duration of the spark plug such that each switching device has a different switching status from each other. After the multispark duration, the drive circuit switches periodically on and off the second transistor with a short switching interval. The switching interval is set such that a relatively low voltage that almost causes a spark is impressed to the spark plug. An ion current detection is implemented by using this voltage as a power source.

Abstract: In a first operative mode, the control unit first causes energy to be stored by the inductor and then connects the inductor to the capacitor so as to form a resonance circuit whose energy is discharged into the primary winding of the coil in order to generate a spark. In a second operative mode, the unit causes a plurality of cycles to be effected to charge the capacitor so as to increase the voltage across its terminals at each cycle and the capacitor is then discharged into the primary winding of the ignition coil in order to generate the spark.

Abstract: An ignition device includes an ignition coil, an ignition plug and ignition control unit. The ignition control unit includes a secondary current adjusting unit that adjusts, in each cycle, an amount of the secondary current after initiating the discharge, a discharge extension detecting unit that detects an amount of extension of the discharge, and a short determination unit that determines whether a discharge-short has occurred. The ignition control unit controls the secondary current control unit such that a first step and a second step are repeatedly executed. The first step decreases the secondary current while keeping the secondary current higher than a predetermined lower current limit, when the extension amount detected by the discharge extension detecting unit is a predetermined extension amount or more. The second step increases the secondary current when the short determination unit determines that a discharge-short has occurred.
