Abstract

See full text

There is provided an ignition apparatus that makes it possible that after a spark discharge starts, a secondary current is reduced so that a plug is suppressed from being consumed. The ignition apparatus is provided with an ignition coil including a primary coil, a secondary coil, and a tertiary coil, a first switching circuit for performing on/off-switching of energization of the primary coil from a power source, a second switching circuit for performing on/off-switching of energization of the tertiary coil, and a controller that performs on/off-control of the first switching circuit so as to generate a secondary current in the secondary coil, thereby causing a spark discharge in an ignition plug, and then turns on the second switching circuit so as to reduce the secondary current through a change in flux in the tertiary coil.
