ABSTRACT:
A combustion state detecting apparatus for an internal combustion engine includes: an ignition plug (2) for generating a spark discharge for igniting an air-fuel mixture in a combustion chamber; an ignition coil (1) for supplying a high voltage to cause the ignition plug (2) to generate the spark discharge; and an ECU (3) for feeding a driving signal for driving the ignition coil (1). An electromotive force (secondary voltage) due to electromagnetic induction when a primary current is caused to flow through a primary winding of the ignition coil (1) in response to the driving signal from the ECU (3) is applied to the ignition plug (2) to detect an ion current generated in the combustion chamber to detect a combustion state in the ignition plug based thereon.
