Abstract
LA INVENCION SE REFIERE A UN DISPOSITIVO DE INYECCION PARA MOTORES DE COMBUSTION INTERNA DE AUTOENCENDIDO. LA REDUCCION DEL RUIDO DE LA COMBUSTION DE MOTORES DIESEL REQUIERE NUEVOS PROCEDIMIENTOS DE INYECCION. SEGUN LA INVENCION SE PRETENDE UNA SUBDIVISION EN PREINYECCION E INYECCION PRINCIPAL. ESTO SE POSIBILITA POR MEDIO DE DOS CONDUCTOS DE INYECCION (3, 4) DE DIFERENTE LONGITUD, CUYA DIFERENCIA DE LONGITUD SE ELIGE PARA QUE LA DIFERENCIA DEL TIEMPO DE MARCHA DE LAS ONDAS DE PRESION CORRESPONDA AL RETARDO DE TIEMPO ENTRE PREINYECCION E INYECCION PRINCIPAL . PARA TENER EN CUENTA LA COMPRENSIBILIDAD DEL COMBUSTIBLE, LOS DOS CONDUCTOS DE INYECCION (3, 4) ESTAN BAJO UNA ALTA PRESION ESTATICA. LA INTERACCION HIDRAULICA DE LOS CONDUCTOS DE INYECCION (3, 4) ENTRE SI SE IMPIDE MEDIANTE RETENCION (8, 9) Y VALVULAS DE DERIVACION (10, 11). MEDIANTE LA INYECCION REGULADA SE REDUCEN CONSIDERABLEMENTE LOS RUIDOS DE LA COMBUSTION.
