Abstract

CIRCUITO ELECTRONICO REGULADOR DE LA INYECCION DE COMBUSTIBLE EN MOTORES DE COMBUSTION INTERNA. EL INYECTOR SE ENERGIZA SEGUN LA CARGA DE UN CONDENSADOR (17), CONECTADO A MASA Y A UNA TARJETA DE CIRCUITO INTEGRADO (12), CUYO TIEMPO DE CARGA Y DESCARGA DEPENDE DEL ESTADO DE UNOS CONMUTADORES QUE CONECTAN O NO UNA SERIE DE RESISTENCIAS CON EL CONDENSADOR (17), DEPENDIENDO ESTAS CONEXIONES DE A TEMPERATURA DEL MOTOR, DETECTADA POR UNA RESISTENCIA (16) VARIABLE CON LA TEMPERATURA, Y DE LA VELOCIDAD DEL CIGUEÑAL, CONOCIDA POR LOS PULSOS PRODUCIDOS EN UNA BOBINA (15) POR UNA RUEDA DE RELUCTANCIA VARIABLE (14).
