PURPOSE:To synthetically process exhaust gas with structure formed in compactness by arranging an ammonia injector and a porous ceramics-made filter carrying a denitration catalyst successively from the upstream side between the outlet of a Diesel engine and the inlet of a supercharger. CONSTITUTION:Exhaust gas in the outlet of a Diesel engine 1 is dynamic pressure-collected by a supercharger 2. Here before the supercharger 2, a denitration catalyst-carrying ceramics porous filter 3 is arranged. While before the filter 3, an ammonia injector 4 is arranged. That is, the filter 3 and the injector 4 are arranged between the outlet of the engine 1 and the inlet of the supercharger 2. Thus by ensuring a temperature necessary for denitration reaction, exhaust gas is synthetically processed by respectively ensuring a filter function and a denitration function or the like while attaining the compactness or the like of a device total unit. |
