Abstract
(EN)
This ignition system is provided with: a main primary coil; a sub primary coil; a secondary coil; a control unit that switches a main primary coil mode from cutoff mode to electrification mode by driving a main IC, switches the main primary coil mode from electrification mode to cutoff mode by ceasing to drive the main IC, switches a sub primary coil mode from cutoff mode to electrification mode by driving a sub IC, and switches the sub primary coil mode from electrification mode to cutoff mode by ceasing to drive the sub IC; and a detection circuit that detects the state of the secondary coil, the ignition system being configured such that when the state of the secondary coil detected by the detection circuit is a non-electrification state, the driving of the sub IC ceases.

Ce système d'allumage est pourvu : d'une bobine primaire principale ; d'une sous-bobine primaire ; d'une bobine secondaire ; d'une unité de commande qui commute un mode de bobine primaire principal du mode de coupure à un mode d'électrification par entraînement d'un CI principal, commute le mode de bobine primaire principal du mode d'électrification à un mode de coupure en arrêtant l'entraînement du CI principal, commute un mode de sous-bobine primaire du mode de coupure au mode d'électrification en entraînant un sous-CI, et commute le mode de sous-bobine primaire du mode d'électrification au mode de coupure en arrêtant l'entraînement du sous-CI ; et un circuit de détection qui détecte l'état de la bobine secondaire, le système d'allumage étant configuré de telle sorte que lorsque l'état de la bobine secondaire détectée par le circuit de détection est un état de non-électrification, l'entraînement du sous-CI cesse.

点火装置は、メイン一次コイルと、サブ一次コイルと、二次コイルと、メインICを駆動させることでメイン一次コイルモードを遮断モードから通電モードに切り替え、メインICの駆動を停止させることでメイン一次コイルモードを通電モードから遮断モードに切り替え、サブICを駆動させることでサブ一次コイルモードを遮断モードから通電モードに切り替え、サブICの駆動を停止させることでサブ一次コイルモードを通電モードから遮断モードに切り替える制御部と、二次コイルの状態を検出する検出回路と、を備え、検出回路によって検出された二次コイルの状態が非通電状態である場合、サブICの駆動が停止するように構成されている。
