Title
(EN) IGNITION CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE
(FR) DISPOSITIF DE COMMANDE D'ALLUMAGE DESTINÉ À UN MOTEUR À COMBUSTION INTERNE
(JA) 内燃機関用点火制御装置
Abstract
(EN)
A control unit (319) in this ignition control device (30) controls switching elements such that stored energy is released from a capacitor (317) (due to a second switching element (314) being turned on) during an ignition discharge (which is started by a first switching element (313) being turned off), thereby supplying primary current to one end of a primary winding (311a), the other end thereof being connected to a DC power supply (312). In particular, the control unit controls the second switching element or a third switching element such that the amount of stored energy released from the capacitor can be varied in accordance with the operating state of an internal combustion engine.
(FR)
L'invention concerne un dispositif de commande d'allumage (30) comportant une unité de commande (319) commandant des éléments de commutation de telle sorte que de l'énergie stockée est libérée d'un condensateur (317) (par l'activation d'un deuxième élément de commutation (314)) durant une décharge d'allumage (qui est démarrée par la désactivation d'un premier élément de commutation (313)), ce qui alimente en courant primaire une extrémité d'un enroulement primaire (311a), l'autre extrémité de celui-ci étant connectée à une alimentation électrique à courant continu (312). En particulier, l'unité de commande réalise la commande du deuxième élément de commutation ou d'un troisième élément de commutation de telle sorte que la quantité d'énergie stockée libérée du condensateur peut être variée conformément à l'état opérationnel d'un moteur à combustion interne.
(JA)
 点火制御装置(30)において、制御部(319)は、点火放電(第一スイッチング素子(313)のオフにより開始される)中に、コンデンサ(317)から蓄積エネルギを放出させる(第二スイッチング素子(314)のオンにより行われる)ことで、一次巻線(311a)の直流電源(312)に接続された一端とは反対の他端側に一次電流を供給すべく、各スイッチング素子を制御する。特に、制御部は、コンデンサからの蓄積エネルギの放出量を内燃機関の運転状態に応じて可変とすべく、第二スイッチング素子又は第三スイッチング素子を制御する。
