PROBLEM TO BE SOLVED: To provide an exhaust gas analysis system capable of reducing the influence of acceleration acting on a differential pressure sensor part in accordance with the movement of the movable body.SOLUTION: The exhaust gas analysis system includes: an exhaust gas flow channel 2 through which exhaust gas flows; a diluted gas flow channel 3 through which diluted gas flows; a main flow channel 4 through which diluted exhaust gas flows; a diluted exhaust gas flow rate measurement mechanism 44 disposed in the main flow channel 4; and a diluted gas flow rate measurement mechanism 32 disposed in the diluted gas flow channel 3. Also, the diluted exhaust gas flow rate measurement mechanism 44 and the diluted gas flow rate measurement mechanism 32 include a pressure sensor part. Then, the pressure-sensitive element of the pressure sensor part in the diluted exhaust gas flow rate measurement mechanism 44 and the pressure-sensitive element of the pressure sensor part in the diluted gas flow rate measurement mechanism 32 are disposed so as to be faced to the same direction such that an acceleration influence accompanying the movement of a movable body is reduced.SELECTED DRAWING: Figure 1 |
