Abstract

UN METODO Y EQUIPO PARA EXAMINAR LAS JUNTAS Y LOCALIZAR CUALQUIER GOTEO EN EL SISTEMA DE SUMINISTRO DE ESCAPE (A) DE UN MOTOR DE COMBUSTION INTERNA CON COMBUSTIBLE DE INYECCION PARA VEHICULOS DE MOTOR. EL EXAMEN ES EFECTUADO MEDIANTE LA ADMISION DE AIRE COMPRIMIDO AL TUBO DE ENTRADA (C) DEL MOTOR A UNA PRIMERA PRESION REGULADA, DETECTANDO EL VALOR DE LA PRESION DE FLUJO ASCENDENTE DEL TUBO DE ENTRADA, DESCARGANDO EL AIRE COMPRIMIDO DESDE EL TUBO DE ENTRADA, Y DETECTANDO LA PRESION DE DESCARGA. LA PRESION DE DESCARGA ES COMPARADA CON LA PRESION DE SUMINISTRO Y, SI ESTA ESTA POR DEBAJO DE UN VALOR PREDETERMINADO, SE INCREMENTA LA PRESION DE SUMINISTRO DE AIRE, PARA ASI IDENTIFICAR LA LOCALIZACION DE LA GOTERA.
