<P>PROBLEM TO BE SOLVED: To prevent a reduction in engine fuel efficiency by preventing an increase in engine back pressure when an exhaust sensor is installed. <P>SOLUTION: The exhaust sensor 10 for measuring exhaust gas component includes a cylindrical sensor body 11 installed outside an exhaust pipe 5 of an engine 1, a gas inlet 12 that is formed at one end of the sensor body 11, and a gas outlet 13 that is formed at the other end of the sensor body 11. The gas inlet 12 is connected between the exhaust pipe 5 and an introduction pipe 16. The gas outlet 13 is connected between the exhaust pipe 5 on the downstream of the communicating part 16a of the introduction pipe 16 and a return pipe 17. Due to the pressure difference between the communicating part 16a of the introduction pipe 16 and the communicating part 17a of the return pipe 17, exhaust gas, after being taken in the sensor body 11 from the gas inlet 12, is discharged from the gas outlet 13. <P>COPYRIGHT: (C)2012,JPO&INPIT |
