の排気ターボ過給機を具備する内燃機関。[Claims for Utility Model Registration] ■ In an internal combustion engine equipped with a turbocharger that uses exhaust gas to turn an exhaust turbine and uses this power to drive a compressor to precompress intake air or air-fuel mixture supplied to the engine, A throttle valve interlocked with an accelerator pedal is disposed in the passage downstream of the compressor, and a bypass passage that bypasses the compressor and one end of which opens upstream of the slot valve is further provided. The exhaust turbo is characterized in that the passage is provided with a passage closing valve for opening and closing the bypass passage, and during acceleration, the passage opening/closing valve is temporarily operated to open the bypass passage. Internal combustion engine equipped with a supercharger. 2. The passage opening/closing valve is operated by a diaphragm device, and the diaphragm device includes a diaphragm to which one end of the passage opening/closing valve is fixed, and a first chamber and a second chamber partitioned by the diaphragm. and a spring member attached to the second chamber to hold the passage opening/closing valve in a closed state, and the first chamber communicates with the suction passage downstream of the throttle valve through a first communication passage and also includes an orifice. During acceleration, as the negative pressure downstream of the throttle valve decreases, the pressure in the second chamber becomes smaller than the pressure in the first shaft, causing H< The internal combustion engine is equipped with an exhaust turbine supercharger according to claim 1, wherein the passage opening/closing valve is actuated poetically against the force of the spring member to open the bypass passage. institution. 3. The second chamber is further communicated with the suction passage downstream of the throttle valve through a second communication passage, and when the boost pressure downstream of the throttle valve exceeds a predetermined value, the second chamber is connected to the intake passage downstream of the throttle valve. An internal combustion engine comprising an exhaust turbo supercharger according to claim 2 of the collected patent application, in which an on-off valve for opening a communication passage is provided. 4. The on-off valve is composed of an electromagnetic on-off valve, and on the other hand, a pressure detector for detecting boost pressure is installed in the suction passage downstream of the throttle valve. the second
An internal combustion engine comprising an exhaust turbo supercharger according to claim 3, which opens a communication passage.
