Abstract
UN SISTEMA DE ENCENDIDO PARA ACCIONAMIENTO DIRECTO DE UN MOTOR DE COMBUSTION INTERNA QUE TIENE UN CONJUNTO DE BOBINA CAPAZ DE FIJARSE EN CADA BUJIA. CADA CONJUNTO DE BOBINA TIENE UN TRANSFORMADOR DE ALTO VOLTAJE PARA PRODUCIR UN VOLTAJE SUFICIENTE PARA OCASIONAR QUE LA BUJIA GENERE UNA CHISPA, UN CAPACITOR INTEGRAL PARALELO CON LA BUJIA, Y UN CIRCUITO SENSOR DE BUJIA ACOPLADO CON EL TRANSFORMADOR DE ALTO VOLTAJE PARA GENERAR UNA SEÑAL DE CONFIRMACION DE CHISPA CUANDO SE GENERA UNA CHISPA. EL CIRCUITO SENSOR DE CHISPA RESPONDE A UNA SEÑAL DE ALTA FRECUENCIA GENERADA EN EL TRANSFORMADOR DE ALTO VOLTAJE DENTRO DE UNA ESCALA DE FRECUENCIA PREDETERMINADA A FIN DE GENERAR LA SEÑAL DE CONFIRMACION DE CHISPA. EL SISTEMA DE ENCENDIDO DE ACCIONAMIENTO DIRECTO ES COMPATIBLE CON LOS MODOS DE FUNCIONAMIENTO DE UN SOLO ENCENDIDO O ENCENDIDO MULTIPLE.
