Abstract

LA INVENCION SE REFIERE A UN SISTEMA DE CONTROL DE EMISIONES MEJORADO. EL SISTEMA TIENE UNA APLICACION PARTICULAR PARA SU USO EN UN MOTOR DE COMBUSTION INTERNA (10) QUE UTILICE COMBUSTIBLES ALTERNATIVOS TALES COMO EL GAS NATURAL. MAS PARTICULARMENTE, LA INVENCION SUMINISTRA UN APARATO Y UN METODO EN LOS QUE SE ELIMINA EL HIDROGENO MEDIANTE UN CATALIZADOR DE ACONDICIONAMIENTO (16) DE LA CORRIENTE DE GASES DE ESCAPE (21) PARA PRODUCIR UN GAS DE ESCAPE ACONDICIONADO (22). UN SENSOR DE OXIGENO DE LOS GASES DE ESCAPE (EGO) (18) ESTA EN COMUNICACION CON EL GAS DE ESCAPE ACONDICIONADO (22) Y GENERA UNA SEÑAL EN RESPUESTA A LA CONCENTRACION DE OXIGENO DETECTADA DE LOS GASES DE ESCAPE ACONDICIONADOS (22). LA MEZCLA DE AIRE/COMBUSTIBLE QUE PENETRA EN EL MOTOR (10) SE AJUSTA MEDIANTE UN MEDIO DE CONTROL DE CIRCUITO CERRADO (14) EN RESPUESTA A LA SEÑAL GENERADA POR EL SENSOR DE EGO (18). LA ELIMINACION DEL HIDROGENO DE LA CORRIENTE DE GASES DE ESCAPE (21) ELIMINA LOS DESPLAZAMIENTOS IMPRODUCTIVOS Y PERMITE QUE EL SENSOR DE OXIGENO (18) Y EL MEDIO DE CONTROL DE CIRCUITO CERRADO (14) CONTROLEN MAS EXACTAMENTE LA RELACION DE AIRE/COMBUSTIBLE. COMO RESULTADO DEL CONTROL MEJORADO SOBRE LA MEZCLA DE AIRE/COMBUSTIBLE QUE PENETRA EN EL MOTOR (10), UN CATALIZADOR PRINCIPAL DE TRES VIAS (20) CONVIERTE DE FORMA OPTIMA LOS COMPONENTES NOCIVOS PRESENTES EN LOS GASES DE ESCAPE ACONDICIONADOS (22) PARA PRODUCIR UNA CORRIENTE DE ESCAPE PURIFICADA (23).
