An engine exhaust gas purifying device, and process, wherein the device provides a catalyst device for treating the exhaust gas, an adsorbing device for adsorbing materials from the exhaust gas and a heat exchanger. The device is configured so that high temperature exhaust gas from the engine passes through a high temperature side of the heat exchanger prior to passing through the adsorbing device. After passing through the adsorbing device, the gas passes through the low temperature side of the heat exchanger and then passes to the catalyst device. In an alternate embodiment of the present invention, the catalyst can be disposed in the low temperature side of the heat exchanger. |
