最高速度制御装置。 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 the 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. A valve body of the valve is connected to a diaphragm that divides the inside of the diaphragm case into a first diaphragm chamber and a second diaphragm chamber, and the supercharging pressure downstream of the blower compressor is supplied to the first diaphragm chamber. is introduced through the boost pressure introduction passage so that the valve body of the blow-off valve is opened by the boost pressure, and the second diaphragm chamber is communicated with the suction passage of the blower compressor or the air cleaner. A suction passage of the blower compressor or a communication passage to the air cleaner is connected to the boost pressure introduction passage, and a connection part of the communication passage to the boost pressure introduction passage is connected to a vehicle speed sensor that indicates that the vehicle speed is below a predetermined value. When the supercharging pressure introduction passage is shut off and the first diaphragm chamber is communicated with the communication passage, when the vehicle speed is higher than a predetermined speed, the communication between the first diaphragm chamber and the communication passage is cut off and the supercharging pressure is reduced. A maximum speed control device for a vehicle equipped with an exhaust turbocharged internal combustion engine, which is equipped with a switching valve that switches to communicate the introduction passage.
