Abstract

EL CONTENEDOR (6) COMPRENDE MEDIOS DE ADSORCION DE OXIDOS DE NITROGENO CONTENIDOS EN ESTOS GASES. SE INICIA UNA PURGA POR UN AUMENTO DE LA RIQUEZA (R) DE LA MEZCLA AIRE/COMBUSTIBLE DE ALIMENTACION DEL MOTOR (1) A PARTIR DE UNA RIQUEZA QUE CORRESPONDE A UNA MEZCLA POBRE O ESTOQUIOMETRICA. SE EVALUA, MEDIANTE UNA TABLA BASADA EN LA TEMPERATURA (T CAT ) Y EN EL NIVEL DE LLENADO (NS/NSC) DEL CONTENEDOR (6) DE OXIDOS DE NITROGENO, LA EFICACIA (EFFNOX, EFFSTOCK) DEL CONTENEDOR EN MATERIA DE ADSORCION DE LOS OXIDOS DE NITROGENO CUANDO EL MOTOR (1) FUNCIONA CON MEZCLA POBRE, Y SE INICIA UNA PURGA DEL CONTENEDOR (6) CUANDO DICHA EFICACIA (EFFNOX; EFFSTOCK) CAE POR DEBAJO DE UN VALOR PREDETERMINADO (EFFMIN), BASADO EN LA TEMPERATURA (T C AT ) DEL CONTENEDOR (6). APLICACION EN UN MOTOR DE COMBUSTION INTERNA QUE PROPULSA UN VEHICULO A MOTOR.
