Abstract

SE DESCRIBE UN METODO PARA REDUCIR LAS EMISIONES TOTALES DURANTE LOS ARRANQUES EN FRIO DE UN MOTOR QUE QUEMA UN COMBUSTIBLE DE HIDROCARBONO Y QUE TIENE UN POSQUEMADOR DISPUESTO CORRIENTE ARRIBA DE UN CONVERSOR CATALITICO. EL METODO COMPRENDE LOS PASOS DE: I) AÑADIR UN EXCESO DE COMBUSTIBLE A LA CARGA DE COMBUSTIBLE DEL MOTOR Y AÑADIR AIRE A LOS GASES DE ESCAPE DEL MOTOR INMEDIATAMENTE DESPUES DE QUE EL MOTOR HAYA EFECTUADO EL PRIMER QUEMADO PARA ASEGURAR LA PRESENCIA EN LA MEZCLA DE GASES DE ESCAPE-AIRE DE CONCENTRACIONES SUFICIENTES DE HIDROGENO Y OXIGENO COMO PARA PERMITIR QUE LA MEZCLA RESULTANTE DE GASES DE ESCAPE/AIRE PUEDA SUFRIR UNA IGNICION Y SE QUEME CON LA LLAMA DEL POSQUEMADOR MIENTRAS QUE ESTE ULTIMO SE ENCUENTRA A UNA TEMPERATURA CERCANA A LA TEMPERATURA AMBIENTE Y II) ENCENDER LA MEZCLA DE GASES DE ESCAPE/AIRE EN EL POSQUEMADOR INMEDIATAMENTE DESPUES DE QUE EL MOTOR SE HAYA ENCENDIDO LA PRIMERA VEZ. EN UNA CONFORMACION MAS ADECUADA DE LA INVENCION, EL COMBUSTIBLE EN EXCESO Y/OEL AIRE ADICIONAL SE REGULAN DESPUES DE QUE SE HAYA PRODUCIDO LA IGNICION EN EL POSQUEMADOR PARA MANTENER LA LLAMA EN EL POSQUEMADOR HASTA QUE AL MENOS PARTE DE LA MATRIZ DE CONVERSOR CATALITICO HAYA ALCANZADO SU TEMPERATURA DE FUNCIONAMIENTO.
