制御装置。A negative pressure operated EGR valve is arranged in the EGR passage that recirculates exhaust gas from the exhaust pipe to the intake pipe, and an EGR modulator is arranged in the middle of the operating negative pressure supply passage to the EGR valve, and the EGR modulator is defined by a diaphragm. The EGR valve has an atmospheric pressure chamber and an exhaust gas chamber, and the operating negative pressure of the EGR valve is adjusted by opening and closing a bleed hole in the operating negative pressure supply passage by a valve body supported on the diaphragm. An EGR valve control device, characterized in that an air introduction hole to the atmospheric pressure chamber is communicated with a clean side of an air cleaner through a conduit.
