- A method for non-intrusive measurement of spark plug fouling, burn quality, pre-ignition and spark characteristics is described. The technique relies on a continuous monitoring of the leakage current to the spark plug centre electrode, via a high voltage diode stand off arrangement. By way of demonstration, the system operation is reported for investigations of cold start plug fouling.
