<P>PROBLEM TO BE SOLVED: To prevent an exhaust sensor sensing part from getting wet by the splash of condensed water adhered to an exhaust pipe, and to start an engine normally even immediately after the formation of the condensed water. <P>SOLUTION: In the installation structure of the exhaust sensor to the exhaust pipe 11 of the internal combustion engine, an exhaust-emission control device 12 is provided in the exhaust pipe 11 of the internal combustion engine in order to remove a toxic substance in exhaust emission. The downstream part 11a of the exhaust-emission control device 12 in the exhaust pipe 11 is formed in a downstream tapered part 11b. The exhaust sensor 18 for sensing components in the exhaust emission is installed in the downstream of the exhaust-emission control device 12. In the exhaust pipe 11, a condensed water splash passage guide means 30 is provided so that the splash passage of the condensed water on the upstream side including the tapered part 11b of the exhaust pipe 11 is changed from an exhaust passing region W passing a component cover 47 covering the sensing part 45 of the exhaust sensor 18, and the passage is guided to a condensed water passing region Z. <P>COPYRIGHT: (C)2007,JPO&INPIT |
