Title (EN) IGNITION SYSTEM
(FR) SYSTÈME D'ALLUMAGE
(JA) 点火装置
Abstract:
(EN) An ignition system (10) comprises 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) connected to a spark plug (80) and magnetically coupled with the primary coil, a first switch (31) that interrupts an electrical pathway between a first terminal (12) and the ground, a second switch (32) that interrupts an electrical pathway between a power source (90) and a second terminal (13), a third switch (33) that interrupts an electrical pathway between the power source and the first terminal, a fourth switch (34) that interrupts an electrical pathway between a connection point and the ground, and a switch control unit (60) that performs opening/closing control for the switches and causes the electrical pathways to be interrupted.
(FR) L'invention concerne un système d'allumage (10) comprenant une bobine primaire (11) comportant un premier enroulement (11a) et un second enroulement (11b) connecté en série au premier enroulement, une bobine secondaire (21) connecté à une bougie d'allumage (80) et accouplée magnétiquement à la bobine primaire, un premier commutateur (31) destiné à interrompre un trajet électrique entre une première borne (12) et la terre, un deuxième commutateur (32) destiné à interrompre un trajet électrique entre une source d'alimentation (90) et une seconde borne (13), un troisième commutateur (33) destiné à interrompre un trajet électrique entre la source d'alimentation et la première borne, un quatrième commutateur (34) destiné à interrompre un trajet électrique entre un point de connexion et la terre, et une unité de commande (60) des commutateurs destinée à effectuer une commande d'ouverture/fermeture des commutateurs et à provoquer l'interruption des trajets électriques.
(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(12)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(13)との間の電気経路を断続する第2スイッチ(32)と、電源と第1端子との間の電気経路を断続する第3スイッチ(33)と、接続点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。
