徴とする排気ターボ過給機付内燃機関。A bypass air supply passage that bypasses the compressor of the supercharger is attached to the air supply passage, and a passage opening/closing valve is provided in the bypass air supply passage, and the bypass air supply passage is downstream of the compressor and downstream of the bypass air supply passage. An air supply switching valve is provided in the upstream part of the branch, and a wastegate valve is further provided in the exhaust passage, and these passage opening/closing valves, the air supply switching valve, and the wastegate valve are operated in conjunction with each other according to the operating state of the engine. When a signal is sent from , the passage opening/closing valve and the waste gate valve are opened in the partial load area, the supply air switching valve is closed, and the passage opening/closing valve and the waste gate valve are closed in the high load area.
When the air supply switching valve opens and the boost pressure in the air supply passage downstream of the downstream branch of the bypass air supply passage increases, the wastegate valve opens and some of the exhaust air escapes, causing abnormal boost pressure. An internal combustion engine with an exhaust turbo supercharger characterized in that a passage opening/closing valve opens when pressure is reached.
