<P>PROBLEM TO BE SOLVED: To provide sampling of an exhaust gas recirculated in-situ from an EGR circuitry, particularly at the return from the EGR, and an exhaust gas in an initial state. <P>SOLUTION: A device for sampling a recirculating exhaust gas from an internal combustion engine, particularly a diesel type internal combustion engine, includes an exhaust gas recirculating circuit 12 having a recirculating gas circulating line 26 having a circulation control valve 32 for the gas, and arranged between exhaust parts 22 and 24 of the engine and intake parts 18 and 20 of the engine. The device includes at least two sampling points 36A, 36B, 36C, and 36D in the recirculating gas circulating line, and distributing instruments 42A, 42B, 42C, and 42D that supply the sampled gas to at least one analyzing device 46A, 46B, 46C, and 46D; 50A, 50B, 50C, and 50D. <P>COPYRIGHT: (C)2009,JPO&INPIT |
