  • Publication number: 20260264010
    Abstract: An exhaust system with a semi-closed cycle includes a main flow path having an inlet node, an outlet node, and a recirculation node; an exhaust gas recirculation flow path that diverts a recirculated exhaust gas from the recirculation node, and recirculates the recirculated exhaust gas to the inlet node; an engine configured to produce an exhaust gas based on a mixture of ambient air and the recirculated exhaust gas; a heat exchanger that transfers heat from a first portion of the exhaust stream to an exchanger fluid, resulting in the exchanger fluid being heated and the first portion of the exhaust stream being cooled to produce a first portion of a cooled exhaust stream; and an absorption chiller that extracts heat from a second portion of the exhaust stream to cool the second portion of the exhaust stream and produce a second portion of the cooled exhaust stream.
