Abstract

SEGUN LA INVENCION, EN LOS INYECTORES (2) DE UN MOTOR (1) PARA EL CUAL LA DURACION DE INYECCION EN FUNCION DE LAS NECESIDADES DEL MOTOR (T INJ M) SE CALCULA POR UN CALCULADOR (21), SE APLICA UNA DURACION DE INYECCION (T INJ A) = T INJ M RGA DE BOTE (16) EXPRESADA POR LA CANTIDAD DE COMBUSTIBLE INTRODUCIDA EN FORMA DE VAPOR ENTRE DOS INYECCIONES CONSECUTIVAS Y CALCULADA EN FUNCION DEL CONTENIDO DE COMBUSTIBLE ESTIMADO DEL CIRCUITO DE PURGA (16, 17, 19) Y DE LA CANTIDAD DE MEZCLA AIRE-VAPOR DE COMBUSTIBLE CONTROLADO POR LA VALVULA (20) DE PURGA DEL BOTE (16). ESTA CANTIDAD SE CALCULA A PARTIR DE LA DIFERENCIA DE PRESION A LA QUE LA VALVULA ES SOMETIDA Y DE SU DURACION DE ABERTURA ENTRE LAS DOS INYECCIONES. APLICACION EN LA CORRECCION DE LA DURACION DE INYECCION Y EN LA MEDICION DEL CONSUMO REAL DE COMBUSTIBLE DE LOS MOTORES DE INYECCION.ACCORDING TO THE INVENTION, INJECTORS (2) OF AN ENGINE (1) FOR WHICH THE INJECTION DURATION DEPENDING ON THE NEEDS OF THE ENGINE (T INJ M) IS CALCULATED BY A CALCULATOR (21), AN INJECTION DURATION IS APPLIED (T INJ A) = T INJ M RANGE OF JAR (16) EXPRESSED BY THE AMOUNT OF FUEL INTRODUCED IN THE FORM OF STEAM BETWEEN TWO CONSECUTIVE INJECTIONS AND CALCULATED DEPENDING ON THE ESTIMATED FUEL CONTENT OF THE PURGE CIRCUIT (16, 17, 19) AND OF THE AMOUNT OF AIR-VAPOR MIXTURE OF FUEL CONTROLLED BY THE VALVE (20) OF BLEEDING (16). THIS AMOUNT IS CALCULATED FROM THE PRESSURE DIFFERENCE TO WHICH THE VALVE IS SUBJECTED AND ITS DURATION OF OPENING BETWEEN THE TWO INJECTIONS. APPLICATION IN THE CORRECTION OF THE INJECTION DURATION AND IN THE MEASUREMENT OF THE REAL CONSUMPTION OF FUEL OF THE INJECTION ENGINES.
