高温時吸気制御装置。[Claims for Utility Model Registration] 1. A first pressure passage and a second pressure passage communicating with an air cleaner are connected in parallel to a pressure chamber of an actuator that suppresses the closing operation of a carburetor throttle valve, and the second pressure passage A temperature sensing valve is provided at the opening on the air cleaner side to close the second pressure passage when the temperature exceeds a set temperature, and a pressure delay valve is provided in the middle of the first pressure passage to delay flow to the air cleaner side. A high-temperature intake air control device, characterized in that a jet is provided in the middle of the second pressure passage. 2. The actuator, the pressure delay valve, and the jet have the function of a dart pot to suppress the sudden closing operation of the carburetor throttle valve during engine deceleration operation. The high temperature intake air control device according to scope 1.
