In the diverting device for exhaust gas that is diverted to a dilution tunnel by a passageway, a pressure detection means is provided downstream of each vent lily or orifice in the exhaust passageway and the diversion passageway, respectively, and a pressure detection means is provided for detecting the operating state of the engine. A means is provided in the engine, and a dilution tunnel upstream of the confluence between the dilution tunnel and the diversion passage, between the confluence and a bench lily or orifice in the diversion passage, or downstream of a bench lily or orifice in the exhaust passage. An exhaust gas flow dividing device characterized in that a pressure regulating valve is provided at one location on the side, and a control means is provided for controlling the opening degree of the pressure regulating valve based on signals from each of the detection means. (2) A small-diameter branch passage with a bench lily or orifice is inserted upstream of the bench lily or orifice provided in the exhaust passage of the engine, and the exhaust gas in the exhaust passage is diverted to the dilution tunnel by the branch passage. In the gas distribution device, pressure detection means are provided on the downstream side of each bench lily or orifice in the exhaust passage and the distribution passage, and a detection means for detecting the operating state of the engine is provided in the engine, and the Pressure adjustment valves are provided in the upstream side of the dilution tunnel and the downstream side of the vent lily or orifice in the exhaust passage at the junction of the dilution tunnel and the diversion passage, respectively, and adjust the respective pressures based on the signals from each of the detection means described above. 1. An exhaust gas distribution device characterized by comprising a control means for controlling the opening degree of a valve.
