Abstract

UN SISTEMA DE INYECCION DE COMBUSTIBLE PARA UN MOTOR DE COMBUSTION INTERNA, TAL COMO UN MOTOR DE COMBUSTIBLE DUAL GASOLEO/GAS DEL TIPO QUE REQUIERE UNA CAPACIDAD DE PROPORCION DE ACTIVACION DESACTIVACION DE SISTEMA TOTAL, DESDE LA MAXIMA TASA DE FLUJO DE COMBUSTIBLE HASTA LA MINIMA TASA DE FLUJO, EN EL ORDEN DE 100 A 1, EMPLEA UNA BOMBA (10) PRINCIPAL DE DESPLAZAMIENTO VARIABLE CONVENCIONAL QUE TIENE UNA PROPORCION DE ACTIVACION SISTEMA COMPLETO. LA SALIDA DE LA BOMBA (10) PRINCIPAL ES RAMIFICADA PARA SUMINISTRAR DOS CAMINOS (14, 16) PARALELOS PARA EL CONDUCTO DE COMBUSTIBLE. CADA CAMINO INCLUYE UNOS MEDIOS (22, 24) DE VALVULA DE PASO ACTUADOS POR PRESION. LOS MEDIOS (22) PRINCIPALES DE VALVULA DE PASO SE ABREN PARA PERMITIR EL FLUJO A TRAVES DEL CAMINO (14) PRINCIPAL PARA EL MOTOR A PRESIONES POR ENCIMA DE UN VALOR RELATIVAMENTE ALTO. LOS MEDIOS (24) SECUNDARIOS DE VALVULA DE PASO SE ABREN PARA PERMITIR EL FLUJO A TRAVES DEL CAMINO SECUNDARIO (16) EN RESPUESTA A UNA RELATIVAMENTE BAJA PRESION A LA SALIDA (12) DE LA BOMBA. Y, UN DISPENSADOR (26) DE CANTIDAD FIJADA DE FLUIDO EN EL CAMINO DE FLUJO SECUNDARIO (16) OPERA EN RESPUESTA A LA APERTURA DE LOS MEDIOS (24) SECUNDARIOS DE VALVULA DE PASO, PARA DESPLAZAR UNA CANTIDAD FIJA DE COMBUSTIBLE A TRAVES DEL CAMINO SECUNDARIO (16) Y DENTRO DEL MOTOR. EN GENERAL EL CAMINO SECUNDARIO (16) EVITA EL AUMENTO DE PRESION DE COMBUSTIBLE SUFICIENTE EN LA SALIDA DE LA BOMBA (10) PRINCIPAL PARA ABRIR LOS MEDIOS (22) PRINCIPALES DE VALVULA DE PASO CUANDO LA PROPORCION DE SALIDA VARIABLE DE LA BOMBA (10) PRINCIPAL ESTA ESTABLECIDA EN LA PARTE INFERIOR DE SU MARGEN. CUANDO LA SALIDA DE LA BOMBA (10) PRINCIPAL ESTA ESTABLECIDA SUFICIENTEMENTE ALTA, LA PRESION AUMENTA EN LA LINEA (12) DE SALIDA DE LA BOMBA (10) PRINCIPAL PORQUE LA PROPORCION DE LIBERACION DE LA BOMBA (10) PRINCIPAL EXCEDE LA PROPORCION EN LA CUAL EL FLUIDO PUEDE ESTAR DISPUESTO EN EL CAMINO (16) SECUNDARIO; EL COMBUSTIBLE ADICIONAL DESPLAZADO POR LA BOMBA (10) PRINCIPAL SE LIBERAPARA EL MOTOR EN CONSECUENCIA, A TRAVES DEL CAMINO (14) PRINCIPAL.
