ABSTRACT:
An ignition apparatus for an internal combustion engine is provided in which malfunctions due to noise induced by a high ignition voltage can be avoided in a reliable manner. A controller controls the ignition timing of a cylinder of the engine in synchronism woth the rotation thereof. A detector 7-13 detects an ion current which is generated between the electrodes of the spark plug upon combustion of an air/fuel mixture in the cylinder. A filter 21 is connected to an input side of the detector for filtering noise contained in the ion current, the noise being induced by the ignition coil upon sparking of the spark plug. The ignition coil has a primary winding connected to the controller and a secondary winding connected to the spark plug. The filter is connected between the detector and a node P2 between the secondary winding of the ignition coil and the spark plug.
