<P>PROBLEM TO BE SOLVED: To provide an exhaust passage structure of a supercharged engine capable of suppressing the occurrence of cracking in a sensor element while suppressing the ununiformity of an exhaust gas flow velocity distribution at the inlet side end of a catalyst. <P>SOLUTION: This exhaust passage structure of a supercharged engine 100 in which a catalytic converter 40 is installed in an exhaust passage 20 further to the downstream side than the turbine 32 of a turbocharger 30 includes a horizontal passage 20A horizontally extending from the position where the turbine is disposed, a curved passage 20B curved from the downstream side of the horizontal passage 20A, a connection passage 20C which extends from the downstream side of the curved passage 20B in a predetermined angle direction relative to the horizontal passage 20A and which is connected to the catalytic converter 40, a partition plate 22 which is formed in the horizontal passage 20A for vertically dividing the inside of the passage, and a sensor 21 which is disposed on the upper side of the horizontal passage 20A further to the downstream side than the partition plate 22 for detecting the operating state of the engine. <P>COPYRIGHT: (C)2010,JPO&INPIT |
