Filed: 2019-07-19
Abstract: To determine an abrasion amount of an ignition plug with high accuracy and to determine presence or absence of abnormality in the ignition plug with high accuracy in performing early ignition and main ignition.SOLUTION: Early ignition is performed to activate an air-fuel mixture at an advance side with respect to main ignition for igniting the air-fuel mixture. An abrasion amount per one time of ignition of an ignition plug is estimated by abrasion amount estimation means. Abrasion amounts of the ignition plug estimated by the abrasion amount estimation means are integrated to acquire an abrasion amount integration value as the total abrasion amount until the current time. The abrasion amount estimation means performs the estimation such that the abrasion amount per one-time of early ignition becomes greater than the abrasion amount per one time of main ignition. On the basis of a value relating to the abrasion amount integration value, presence or absence of abnormality of the ignition plug (replacement timing or not) is determined.SELECTED DRAWING: Figure 20
