装置。[Claims for Utility Model Registration] A main body case that has a valve port, a valve body that is housed in the main body case and controls the opening and closing of the valve port, and a temperature control system for the intake air supplied to the engine. and a temperature-sensitive drive member that drives the valve body in response to the temperature-sensitive drive member, and the temperature-sensitive drive member drives the valve body to control the opening and closing of the valve port, thereby controlling intake air supplied to the engine. In an engine intake air temperature compensator that controls the magnitude of negative pressure applied to a vacuum motor that controls the temperature of intake air supplied to the engine, and introduces the deficiency of the intake air into the intake passage downstream of the throttle valve. The temperature-sensitive driving member is made of a plurality of shape memory alloys having different temperature characteristics, and each shape memory alloy remembers only one different shape. Compensation device.
