Title: Abrasion amount estimation device and abnormality determination device for ignition plug
Inventor: KAI TATSUYA
IPC: F02P17/12
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 main ignition and additional ignition.SOLUTION: An engine executes additional ignition after main ignition for igniting an air-fuel mixture. An abrasion amount per one time of main ignition on the ignition plug and an abrasion amount per one time of additional ignition are estimated by abrasion amount estimation means. The abrasion amount per one time of main ignition and the abrasion amount per one time of additional ignition, estimated by the abrasion amount estimation means are integrated by abrasion amount integration means, and the abrasion amount integration value as the total abrasion amount until the current time is acquired. The abrasion amount estimation means performs the estimation such that the abrasion amount per one time of additional ignition becomes smaller 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 14
