ことを特徴とするエンジンの吸気温度制御装置。an outside air introduction passage that communicates with the intake passage of the engine; a heated air passage that merges with the outside air introduction passage; and a heated air passage that is provided at the junction of the outside air introduction passage and the heated air passage; It consists of a control valve that opens and closes an opening to control the mixing ratio of outside air and heated air taken into the engine, and a diaphragm device that gives an opening and closing action to the control valve, and the diaphragm device is partitioned by a diaphragm. the diaphragm is combined with the control valve so that the control valve is pushed in the opening direction by negative pressure introduced into the first chamber; In the engine intake air temperature control device connected to the intake passage on the downstream side of the engine throttle valve, a venturi negative pressure passage connecting the second chamber of the diaphragm device to the venturi portion of the intake passage is provided. Features an engine intake air temperature control device.
