An engine supercharger pressure relief device comprises an intake manifold, an intake rubber tube and a mechanical pressure relief valve, and is technically characterized in that the intake manifold, the intake rubber tube and the mechanical pressure release valve are respectively connected with a three-way exhaust solenoid valve by connecting rubber tubes. According to the engine supercharger pressure relief device, the duty cycle of the exhaust solenoid valve is controlled by ECU calibration, mechanical opening is controlled by the negative pressure of an exhaust manifold, and further the mechanical pressure relief valve performs pressure relief on high-pressure gas in an intake system pipeline; finished-automobile NVH (Noise Vibration and Harshness) operating requirements are met in a limited engine arrangement space.
