Abstract

EL DISPOSITIVO SE APLICA ESPECIALMENTE EN LA INYECCION MULTIPUNTO EN MOTORES DE AUTOMOVIL. CONSTA DE AL MENOS UN INYECTOR (34) Y DE UN CIRCUITO ELECTRONICO DE CONTROL (46) ENLAZADO A UNOS CAPTADORES DE PARAMETROS DE FUNCIONAMIENTO DEL MOTOR, EN ESPECIAL DE LA VELOCIDAD DE ESTE ULTIMO, Y SUMINISTRANDO AL INYECTOR UNAS SEÑALES PERIODICAS DE RELACION CICLICA FUNCION DE DICHOS PARAMETROS, EN SINCRONISMO CON LOS MOVIMIENTOS DEL MOTOR DURANTE EL FUNCIONAMIENTO NORMAL DEL MISMO. EL CIRCUITO ELECTRONICO DE CONTROL (46) ESTA CONSTITUIDO DE FORMA QUE SE APLIQUEN AL INYECTOR O A CADA INYECTOR (34) UNAS SEÑALES ASINCRONAS, DE FRECUENCIA MUY SUPERIOR A LA QUE PROPORCIONARIA LA LEY DE FUNCIONAMIENTO NORMAL, TANTO TIEMPO COMO LA VELOCIDAD DEL MOTOR TARDE EN ALCANZAR UN UMBRAL PREDETERMINADO A PARTIR DEL COMIENZO DEL LANZAMIENTO.
