SYSTEM AND METHOD FOR CONTROLLING FLUID FLOW INTO AND/OR OUT OF A CATALYTIC HEAT EXCHANGER BASED ON A CATALYST TEMPERATURE

摘要

A system includes a heat exchanger and a fluid flow control module. The heat exchanger includes a substrate, a catalyst applied to the substrate, and fluid passages. Exhaust gas from an engine flows through the heat exchanger and a working fluid in the fluid passages absorbs heat from the exhaust gas. The fluid flow control module controls fluid flow from the heat exchanger based on a temperature of the catalyst.
