Abstract

UN PROCEDIMIENTO PARA CALIBRAR LOS INYECTORES (I) DE UN SISTEMA DE INYECCION DE UN MOTOR DE COMBUSTION INTERNA (M) CON EL QUE SE PUEDEN COMPENSAR LAS DIFERENTES MAGNITUDES DE FLUJO DE LOS INYECTORES (I) MONTADOS EN EL MOTOR (M), DEBIDO A LAS TOLERANCIAS DE PRODUCCION DE LOS INYECTORES (I), PARA VOLVER A IGUALAR LOS INYECTORES (I) CON UN EQUILIBRIO CONSIGUIENTE DE LA COMBUSTION Y UNA MEJORA GENERAL DEL RENDIMIENTO DEL MOTOR (M). EL PROCEDIMIENTO SE BASA EN LA DETERMINACION DE LAS MAGNITUDES DE FLUJO DE LOS INYECTORES (I) TANTO CON BAJAS ADMISIONES (MARCHA LENTA) Y CON ALTAS ADMISIONES (ACELERACION) A BASE DE MEDIR LOS IMPULSOS DEL PAR SUMINISTRADO POR CADA CILINDRO DEL MOTOR (M) A TRAVES DE UN PROCEDIMIENTO DE MEDICION DEL PAR DINAMICO.
