Novel heat-integrated concepts for efficient automotive exhaust gas purification are presented. The general design consists of a counter-current heat exchanger coupled with purification devices. Transient and steady state experiments were carried out both in lab scale and on an engine test bench. The results show effective heat recovery at acceptable pressure drop. Comparative simulation studies show the advantages of the system under drive cycle conditions.
