Abstract: 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.

Abstract: A system for reducing ammonia in exhaust gas generated from a lean burn internal combustion engine includes an oxidation catalyst, a selective reduction catalyst (SCR), a cooling unit, and a three-way catalyst. Exhaust gas generated by the engine passes through the oxidation catalyst to oxidize carbon monoxide from the exhaust gas to form carbon dioxide. Nitrous oxide (NOx) compounds in the exhaust gas are reduced in the SCR to form nitrogen and water. The exhaust gas is then cooled in a cooling unit and then passed over the three-way catalyst. The three-way catalyst causes ammonia in the cooled exhaust stream to react to form less harmful compounds, such as nitrogen and water.
