Claims

[Claims for Utility Model Registration] A compressor installed in the intake system is connected to a turbine installed in the exhaust system through the same drive shaft. In an internal combustion engine equipped with an exhaust turbo supercharger that is driven by the engine and supplies pressurized air to the internal combustion engine, the exhaust gas is diverted to the downstream side of the turbine by branching from the upstream side of the exhaust gas inlet of the turbine. an exhaust bypass passage for opening and closing the exhaust bypass passage; and a first exhaust bypass passage for opening and closing the exhaust bypass passage.
a bypass opening/closing valve, an intake/pass passage provided in the intake system for bypassing the suction port side and discharge port side of the compressor, and a second bypass valve provided in the intake bypass passage for opening and closing the same. A pressure chamber is formed in a passage connecting the discharge port side of the compressor and the downstream side of the intake bypass passage to close the passage and raise the pressure to a predetermined pressure using the pressure air from the discharge port. 1. An internal combustion engine with an exhaust turbo supercharger, comprising: a gate valve for controlling the pressure in the pressure chamber; and gate valve opening control means for detecting the pressure in the pressure chamber and controlling the opening of the gate valve.
