Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA EL CONTROL DE CALENTAMIENTO DE UN CONVERTIDOR (8,14,15,16) CATALITICO QUE PUEDE SER RAPIDAMENTE CALENTADO DE FORMA ELECTRICA, AL MENOS EN UNA REGION (8) CORTA, Y ESTA COLOCADO POR DEBAJO DE UN MOTOR (1) DE COMBUSTION INTERNA DE UN VEHICULO A MOTOR. EL CALENTADOR (13) ELECTRICO ESTA CONECTADO DESPUES DE UN RETRASO CORTO QUE SIGUE AL ARRANQUE DEL MOTOR (1), SI LA RELACION DE CAMBIO DE TEMPERATURAS EN LA REGION (8) CALENTABLE DEL CONVERTIDOR (8,14,15,16) CATALITICO ORIGINADO MEDIANTE CALENTAMIENTO EN LOS GASES DE ESCAPE DEL MOTOR (1) LLEGA A SER APROXIMADAMENTE LA MISMA O MENOR QUE LA RELACION DEL CAMBIO DE TEMPERATURAS OBTENIBLE MEDIANTE CALENTAMIENTO ELECTRICO. CON ELLO EL CALENTADOR SE CONECTA DESPUES DE 3 HASTA 10 SEG., Y EL MOTOR (1) RUEDA CON PREFERENCIA DE FORMA INICIAL A UNA ALTA VELOCIDAD DE VACIO Y DISPONE DE UNA MEZCLA POBRE Y A VELOCIDAD DE VACIO INFERIOR UNA MEZCLA RICA. LA ADAPTACION DE LOS INTERVALOS DE CALENTAMIENTO Y EL CONTROL DEL MOTOR ASEGURA LA UTILIZACION OPTIMA DE LA POTENCIA ELECTRICA PARA EL CALENTAMIENTO DEL CONVERTIDOR (8,14,15,16) CATALITICO DE FORMA RAPIDA. LA TEMPERATURA EXTERIOR, LA TEMPERATURA DEL MOTOR O LA TEMPERATURA DEL MOTOR PUEDEN SER TENIDAS EN CUENTA TAMBIEN EN EL ESTABLECIMIENTO DEL PRINCIPIO DE CALENTAMIENTO DE MANERA PRECISA. ESTO SIGNIFICA QUE LA POTENCIA ELECTRICA DISPONIBLE SE UTILIZA DE LA MEJOR MANERA POSIBLE.
