Abstract

See full text

The objective is to obtain an internal-combustion-engine ignition apparatus that raises the ignitability at a time when a smolder occurs. An internal-combustion-engine ignition apparatus having a main combustion chamber and a subsidiary combustion chamber includes

    an ignition plug,an ignition coil having a primary coil, a secondary coil, and a tertiary coil,a first switching circuit that turns on or off energization of the primary coil,a second switching circuit that turns on or off energization of the tertiary coil, anda control apparatus that estimates a combustion state, that performs on/off-control of the first switching circuit so that a spark discharge is produced in the ignition plug and that performs on/off-control of the second switching circuit so that magnetic flux in the tertiary coil is changed so as to increase a secondary current, when deterioration of a combustion state has been estimated.
