Claims

[Claims for Utility Model Registration] 1. Provide an air passage for supplying correction air to the intake passage downstream of the carburetor throttle valve, and provide a temperature sensing valve that opens and communicates the air passage when a set temperature is reached;
An intake air control device for an internal combustion engine, comprising an air increasing mechanism that operates in accordance with the operation of the temperature sensing valve to increase the amount of correction air to the intake passage as the temperature rises. 2 A first chamber and a second chamber are defined by a dividing body in the frame, and the air passage is provided which communicates with the intake passage on the downstream side of the carburetor throttle valve, and the air passage is opened to the first chamber. and a first air passage whose starting end opens to the first chamber and whose end opens to the intake passage, and when the set temperature is reached, the first air passage The temperature sensing valve that opens and communicates with the first air passage is provided, and the temperature sensing valve that operates as the temperature rises opens and closes the air increasing mechanism to open and connect the first chamber and the second chamber. Utility model registration claim 1, wherein a valve is provided, and a second air passage communicating with the intake passage is opened in the second chamber.
An intake control device for an internal combustion engine as described in 2. 3 The frame body has the first chamber, the second chamber, and the third chamber, and when the temperature further increases, the second chamber and the third chamber are opened by the operation of the first release valve. Claim 2 of the Utility Model Registration Claim: Another release valve constituting the air increasing mechanism is provided for open communication, and a third air passage communicating with the intake passage is provided in the third chamber. intake control device for internal combustion engines.
