A bypass passage connecting the upstream side and the downstream side of the blower compressor in the exhaust turbo supercharger installed in the internal combustion engine is provided, and in the bypass passage,
In an exhaust turbocharged internal combustion engine, the exhaust turbocharged internal combustion engine is provided with a blow-off valve whose valve body opens against a spring when the boost pressure downstream of the blower compressor increases. The valve body of the valve is provided with a large diameter part for pushing up on the outside of the sealing portion against the valve seat, and the inside of the valve body is divided into a first diaphragm chamber and a second diaphragm chamber. connected to a diaphragm, and applies supercharging pressure downstream of the blower compressor to the first diaphragm chamber through a supercharging pressure introduction passage such that the supercharging pressure opens the valve body of the blow-off valve. introducing the second diaphragm chamber to the dust side chamber of the air cleaner or the atmosphere, while connecting the supercharging pressure introduction passage with a communication passage to the clean side chamber of the air cleaner or the suction passage of the blower compressor, The connecting portion of the communication passage to the boost pressure introduction passage includes a first diaphragm chamber that connects the first diaphragm chamber to the communication passage by blocking the boost pressure introduction passage when the vehicle speed is below a predetermined value in relation to a vehicle speed sensor of the vehicle. death,
An exhaust turbocharged internal combustion engine is provided with a switching valve that operates to cut off communication to a communication passage of a first diaphragm chamber and communicate with a supercharging pressure introduction passage when the vehicle speed of the vehicle exceeds a predetermined value. Maximum speed control device for the vehicle equipped with it.
