SPARK PLUG ABRASION DETECTING METHOD AND ITS DEVICE

PURPOSE: To prevent nonconformity and a misfire caused by abrasion of a spark plug, and replace only the spark plug which must be replaced. CONSTITUTION: A load of an engine is detected (14), and voltage inputted to a spark plug 1 by an electric cord 6 is detected. When the detected voltage is large...

Zusammenfassung:	PURPOSE: To prevent nonconformity and a misfire caused by abrasion of a spark plug, and replace only the spark plug which must be replaced. CONSTITUTION: A load of an engine is detected (14), and voltage inputted to a spark plug 1 by an electric cord 6 is detected. When the detected voltage is large when compared (12) with a reference value set on the basis of the detected load, an abnormal signal is outputted (13).
