Title (EN) IGNITION DEVICE
(FR) DISPOSITIF D'ALLUMAGE
(JA) 点火装置
Abstract:
(EN) An ignition device (10) is equipped with: a primary coil (11) having a first winding (11a) and a second winding (11b) connected in series with the first winding; a secondary coil (21) which is connected to a spark plug (80) and is magnetically coupled to the primary coil; a first switch (31) for interrupting the electrical path between a first terminal and a ground; a second switch (32) for interrupting the electrical path between a power source (90) and a second terminal; a third switch (33) for interrupting the electrical path between the power source and a connection point; a fourth switch (34) for interrupting the electrical path between the second terminal and the ground; and a switch control unit (60) for interrupting each of the electrical paths by controlling the switching of each of the switches.
(FR) L'invention concerne un dispositif d'allumage (10) équipé : d'une bobine primaire (11) comportant un premier enroulement (11a) et un second enroulement (11b) monté en série avec le premier enroulement ; d'une bobine secondaire (21) qui est branchée sur une bougie d'allumage (80) et qui est magnétiquement couplée à la bobine primaire ; d'un premier commutateur (31) permettant d'interrompre le passage électrique entre une première borne et une masse ; d'un deuxième commutateur (32) permettant d'interrompre le passage électrique entre une source d'alimentation (90) et une seconde borne ; d'un troisième commutateur (33) permettant d'interrompre le passage électrique entre la source d'alimentation et un point de branchement ; d'un quatrième commutateur (34) permettant d'interrompre le passage électrique entre la seconde borne et la masse ; et d'une unité de commande de commutateur (60) permettant d'interrompre chacun des passages électriques par commande de la commutation de chacun des commutateurs.
(JA) 点火装置(10)は、第1巻線(11a)及び第1巻線と直列に接続された第2巻線(11b)を有する1次コイル(11)と、点火プラグ(80)に接続され、1次コイルと磁気的に結合される2次コイル(21)と、第1端子とグランドとの間の電気経路を断続する第1スイッチ(31)と、電源(90)と第2端子との間の電気経路を断続する第2スイッチ(32)と、電源と接続点との間の電気経路を断続する第3スイッチ(33)と、第2端子とグランドとの間の電気経路を断続する第4スイッチ(34)と、各スイッチの開閉制御を実行して、各電気経路を断続させるスイッチ制御部(60)と、を備える。
