Abstract

Se proporcionan realizaciones para reactivar un catalizador. En un ejemplo, un método para reactivar un catalizador acoplado a un motor comprende cuando el motor se reinicia después de la desactivación, lo cual ajusta el nivel de enriquecimiento del combustible sobre la base de una duración del apagado del motor y la cantidad de aire en el motor durante el reinicio.
