Abstract
There is provided an internal combustion engine ignition apparatus that can effectively raise the ignitability of an inflammable fuel-air mixture, by applying electric power corresponding to the combustion state of an internal combustion engine. A combustion state detection apparatus detects an combustion state inside a combustion chamber of the internal combustion engine; based on the combustion state detected by the combustion state detection apparatus in accordance with an operation state of an ignition coil apparatus, a current supply apparatus supplies an AC current to a spark discharge path formed in the gap of an ignition plug; then, a control apparatus controls the output of the current supply apparatus.
Claims12
An internal combustion engine ignition apparatus comprising:
- an ignition plug that is provided with two or more electrodes facing each other through a gap and produces a spark discharge in the gap so that an inflammable fuel-air mixture inside a combustion chamber of an internal combustion engine is ignited;
- an ignition coil apparatus that supplies a predetermined ignition voltage to the ignition plug so as to form a spark discharge path in the gap;
- a resonance apparatus that forms a band-pass filter;
- a current supply apparatus that supplies an AC current to the spark discharge path formed in the gap, by way of the resonance apparatus;
- combustion state detection apparatus that detects an combustion state inside the combustion chamber of the internal combustion engine;
- and
- a control apparatus that controls an output of the current supply apparatus, based on the combustion state detected by the combustion state detection apparatus in accordance with an operation state of the ignition coil apparatus.
