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.
