Abstract

LA INVENCION SE REFIERE A UN DISPOSITIVO PARA INYECCION DE COMBUSTIBLE EN MOTORES DE COMBUSTION INTERNA CON UNA TOBERA DE INYECCION (5), A LA CUAL SE ALIMENTA EL COMBUSTIBLE POR MEDIO DE UN DISPOSITIVO A PRESION QUE COMPRENDE UNA BOMBA ACELERADORA DE COMBUSTIBLE (1) Y UN DISPOSITIVO RETARDADOR DE COMBUSTIBLE (6), EL CUAL CUANDO ES ACTIVADO, CONVIERTE LA ENERGIA CINETICA DEL COMBUSTIBLE ACELERADO BRUSCAMENTE EN UNA ONDA DE CHOQUE DE PRESION QUE CAUSA QUE EL COMBUSTIBLE SEA INYECTADO A TRAVES DE LA TOBERA DE INYECCION (5). DE ACUERDO CON LA INVENCION, SE EMPLEA UNA BOMBA ACELERADORA DE COMBUSTIBLE (1) QUE TRABAJA DE MODO INTERMITENTE. ESTA BOMBA (1) Y EL DISPOSITIVO RETARDADOR (6), CON PREFERENCIA ACCIONADO ELECTRICAMENTE, SON CONTROLADOS, CON PREFERENCIA, POR UN DISPOSITIVO DE CONTROL COMUN (8). POR ELLO SE LOGRA QUE EL DISPOSITIVO DE INYECCION SE PUEDA ACCIONAR CON POCA ENERGIA UTILIZADA DE MODO OPTIMO, LO QUE HACE POSIBLE INYECTAR COMBUSTIBLE DE MODO CONTROLADO CON PRECISION MUY RAPIDAMENTE, ASI COMO DESACOPLADO DE LAS OPERACIONES MOTORIZADAS.
