Title:
リーンNOx吸着体後処理システムにおける熱変動の管理
Document Type and Number:
Japanese Patent JP2007502385
Kind Code:
A
Abstract:
A method and apparatus manage heat in exhaust gas in an aftertreatment system that employs a lean NOx adsorber. A de-sulfation hot line and cooling line are employed to control exhaust gas temperatures for adsorption, regeneration and de-sulfation cycles of the aftertreatment system where each cycle can require different chemical and exhaust gas temperatures independent of the engine operation. The method and apparatus include a SOx adsorber to provide greater system durability.
