Abstract
A system and method for treating an engine exhaust is provided. In particular, waste heat from an engine exhaust is stored in a latent heat storage structure through a controllable heat exchanger and a selective catalytic reduction (SCR) catalytic converter is heated by the stored thermal energy in the latent heat storage structure using the controllable heat exchanger. The exhaust treatment system includes a selective catalytic reduction catalytic converter that has an inlet for connecting to an internal combustion engine to intake an engine exhaust and an outlet to output a catalytically treated engine exhaust. The system further includes a latent heat storage structure and a controllable heat exchanger for selectively exchanging heat to and from the catalytic converter and the latent heat storage structure.
