摘要： An exhaust aftertreatment system includes a first stage catalytic converter, a second stage catalytic converter, and a conduit extending from the first stage catalytic converter to the second stage catalytic converter. The conduit passes through an exhaust gas intercooler, between the first and second stage catalytic converts, that reduces the temperature of the exhaust to about 300° F. to about 500° F. Air is ejected into the exhaust conduit to increase the oxygen concentration in the exhaust before it passes through the second stage catalytic converter. The air can be ejected from an air ejection conduit that extends to an engine charger compressor or a compressed air conduit that extends from the engine charger compressor, such as a turbo charger and/or a supercharger, to the engine. A gas particulate filter can be disposed in the exhaust conduit or it can be integrated with the second stage catalytic converter, for example as a catalyzed gas particulate filter.

摘要： An engine radiator cooling fluid circuit and an exhaust gas intercooler (EGI) radiator cooling fluid circuit are fluidically in parallel with one another. The engine radiator cooling fluid circuit extends from the radiator to an engine associated with a vehicle or a stationary system such as a CHP system. The EGI radiator cooling fluid circuit extends from a radiator to an EGI that cools exhaust gas as it flows through an exhaust conduit that extends from a first catalytic converter to a second catalytic converter. The radiator cooling fluid circuits can share a common radiator coil or each radiator cooling fluid circuit can be associated with a respective radiator coil in the radiator. A gas particulate filter can be coupled to the exhaust conduit or the second catalytic converter. An air-driven exhaust gas ejector (EGE) such as an engine charger compressor injects air into an inlet port in the exhaust conduit.
