STUDY ON SPARK PLUG CARBON FOULING

To determine the spark plug fouling mechanism, the structures and properties of the deposit were investigated mainly by using x-ray and electron microscopic techniques. The deposit was found mainly to consist of a graphitic carbon black with highly dense network structure when the insulation resistance of the spark plug was an indicating extremely small value. Further carbon depositing processes were observed by several dynamic analyzers such as high speed flame pictures.
