Abstract

um dispositivo de ignição (1) é provido com: um elemento de comutação de ignição (2); um capacitor (3); um elemento de comutação de pré-acionamento (5); e um circuito de corrente contínua desligado (4off). o elemento de comutação de ignição (2) está conectado a um enrolamento primário (11) de uma bobina de ignição (10). o capacitor (3) está conectado a um terminal de controle (21) do elemento de comutação de ignição (2). o elemento de comutação de pré-acionamento (5) está conectado em paralelo com o capacitor (3). o circuito de corrente contínua desligado (4off) está eletricamente conectado entre o terminal de controle (21) e o capacitor (3). o circuito de corrente contínua desligado (4off) descarrega, em corrente contínua, carga elétrica acumulada no capacitor (3).an igniter (1) is provided with: an ignition switching element (2); a capacitor (3); a pre-drive switching element (5); and a DC circuit disconnected (4off). the ignition switching element (2) is connected to a primary winding (11) of an ignition coil (10). the capacitor (3) is connected to a control terminal (21) of the ignition switching element (2). the pre-drive switching element (5) is connected in parallel with the capacitor (3). the DC circuit disconnected (4off) is electrically connected between the control terminal (21) and the capacitor (3). the direct current circuit disconnected (4off) discharges, in direct current, the electrical charge accumulated in the capacitor (3).
