Abstract: An ignition apparatus includes a blow-off determining unit. The blow-off determining unit determines, when a secondary electric current drops below a predetermined threshold value Ia during a determination period, that blow-off has occurred; the determination period is a predetermined time period ΔT from the start of a spark discharge by a main ignition circuit. Further, when it is determined that blow-off has occurred during a main ignition (full-transistor ignition), it is controlled to perform a continuing spark discharge after the main ignition in a next cycle. Moreover, a secondary electric current command value I2a in performing the continuing spark discharge is set to an electric current value that is obtained by adding a predetermined electric current value α to the predetermined threshold value Ia used in the blow-off determination. Consequently, in the next cycle, it is possible to reliably prevent blow-off, thereby reliably preventing a misfire.

Abstract: There is provided a leakage detection apparatus that can accurately detect a leakage condition in an internal combustion engine having a cylinder resting function. An ignition plug provided in the combustion chamber of a cylinder is made to generate an ignition signal at least once when based on an instruction from a cylinder resting control unit, a fuel injection valve and a valve driving mechanism are stopping the operation thereof; the leakage condition of the ignition plug is detected based on an output signal generated by an ion current detection circuit at a timing other than the timing when ignition discharge is caused.
