Abstract

SE DESCRIBE UN METODO DE DIAGNOSTICO QUE INCLUYE LOS PASOS SIGUIENTES: GENERAR UNA SEÑAL DE PRESION (S{SUB,P}) RELACIONADA CON LA PRESION DEL COMBUSTIBLE DE UN SISTEMA DE INYECCION (1) DE UN MOTOR (2); COMPARAR LA SEÑAL DE PRESION (S{SUB,P}) CON UN VALOR DE PRESION DE REFERENCIA (P{SUB,O}); DETERMINAR EL ESTADO DE FUGA DE COMBUSTIBLE DEL SISTEMA DE INYECCION (1) CUANDO LA SEÑAL DE PRESION (S{SUB,P}) ES MENOR QUE EL VALOR DE PRESION DE REFERENCIA (P{SUB,O}); REDUCIR LA CANTIDAD DE COMBUSTIBLE INYECTADO EN LOS CILINDROS (3) DEL MOTOR (2) CUANDO SE DA UN ESTADO DE FUGA; CALCULAR UN VALOR DE PARTICIPACION (C{SUB,I, I}) DADO POR CADA CILINDRO (3) PARA EL VALOR DEL PAR DE TRABAJO (C{SUB,U}) GENERADO POR EL MOTOR (2); COMPARAR CADA VALOR DE PARTICIPACION (C{SUB,I, I}); DETERMINAR UN ESTADO DEL INYECTOR ABIERTO-ATASCADO CUANDO AL MENOS UNO DE LOS VALORES DE PARTICIPACION (C{SUB,I, I}) ES MAYOR QUE EL VALOR DE PARTICIPACION DE REFERENCIA RESPECTIVO (C{SUB,O, I}); DETERMINAR UN ESTADO DE ERROR DEL CIRCUITO DE SUMINISTRO CUANDO LOS VALORES DE PARTICIPACION F(C{I,I}) SON MENORES QUE LOS VALORES DE PARTICIPACION DE REFERENCIA RESPECTIVOS (C{SUB,O,I}).
