<p><P>PROBLEM TO BE SOLVED: To provide an exhaust gas denitration device and an internal combustion engine suppressing deterioration in exhaust gas denitration efficiency and suppressing a response delay of a supercharger. <P>SOLUTION: The exhaust gas denitration device includes: a denitration part 21 denitrating exhaust gas emitted from an engine body 3; an upstream flow passage 5 leading the exhaust gas to the denitration part 21 from the engine body 3 through the supercharger 4; an upstream bypass flow passage 6 leading the exhaust gas from the engine body 3 to the denitration part 21 while bypassing the supercharger 4; flow rate controlling parts 61 and 62 controlling a flow rate of the exhaust gas flowing through the upstream bypass flow passage 6; a downstream flow passage 7 through which the exhaust gas emitted from the denitration part 21 flows; and a downstream bypass flow passage 8 leading the exhaust gas emitted from the supercharger 4 to the downstream flow passage 7 while bypassing the denitration part 21. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
