Abstract: An exhaust system includes a light-off catalyst, an exhaust system component, and at least one H2O trap. The exhaust system component is upstream from the light-off catalyst and includes catalyst material, the catalyst material configured to store hydrocarbons during a period when the light-off catalyst is warming up to a light-off temperature. The at least one H2O trap is at or upstream from the exhaust system component and is configured to perform H2O adsorption and desorption to increase a length of time for the exhaust system component to reach a hydrocarbon release temperature and prevent the exhaust system component from reaching the hydrocarbon release temperature prior to the light-off catalyst reaching the light-off temperature.

Abstract: An exhaust gas treatment system including: an internal combustion engine comprising an exhaust gas outlet; a first three way catalyst downstream of the exhaust gas outlet, wherein the first three way catalyst receives an exhaust output from the exhaust gas outlet; a hydrocarbon trap downstream of the first three way catalyst, wherein the hydrocarbon trap receives an exhaust output from the first three way catalyst; an exhaust heating unit downstream of the hydrocarbon trap, wherein the exhaust heating unit receives an exhaust output from the hydrocarbon trap; and a second three way catalyst downstream of the exhaust heating unit, wherein the second three way catalyst receives an exhaust output from the heating unit, wherein an air injection port is configured to selectively deliver a stream of air upstream of the hydrocarbon trap and downstream of the first three way catalyst.

Abstract: An apparatus for mitigating fouling within a heat exchanger device includes an internal combustion engine and an external exhaust gas recirculation (EGR) circuit. The internal combustion engine is fluidly coupled to an intake gas manifold upstream of the engine and an exhaust gas manifold downstream of the engine. The EGR circuit is fluidly coupled to the exhaust gas manifold at a first end and is configured to selectively route back exhaust gas flow as EGR flow into the intake gas manifold at a second end. The EGR circuit includes the heat exchanger device for cooling the EGR flow prior to entering the intake manifold and a surface deposit removing device configured to remove surface deposit build-up from within the heat exchanger device when the surface deposit removing device is activated.

Abstract: An exhaust gas recirculation (EGR) cooler for cooling exhaust gas via a coolant includes at least one channel having an inlet and an outlet, and a casing defining a cooling chamber for carrying the coolant around the at least one channel. The exhaust gas is flowable through the at least one channel from the inlet to the outlet. At least a portion of the at least one channel is variable between a fully compressed position and an uncompressed position. The casing includes a coolant inlet and a coolant outlet through which the coolant enters and exits the cooling chamber. The casing also includes an exhaust gas inlet from which the exhaust gas enters the at least one channel, and an exhaust gas outlet into which the exhaust gas exits the at least one channel.
