特徴とするエンジンの燃料供給量調整部材の制御装置。The inside of the casing is divided into two by a diaphragm, one is an atmospheric pressure chamber and the other is a negative pressure chamber, and the negative pressure chamber is provided with a spring that biases the diaphragm toward the atmospheric pressure chamber. By connecting the other end of the iron with one end supported to the fuel supply amount adjusting member, it is possible to control the opening degree of the fuel supply amount adjusting member according to the amount of displacement of the diaphragm. A first branch passage and a second branch passage are connected to a negative pressure source via a negative pressure passage, and branch from the negative pressure passage and open to the atmosphere, and a negative pressure regulator is provided in the first branch passage. and an on-off valve located upstream of the negative pressure regulator, and the on-off valve is interposed in the second branch passage, and the front spring is located upstream of the negative pressure regulator when the ambient temperature is below a predetermined set value. 1. A control device for a fuel supply amount adjusting member for an engine, characterized in that the control device is made of a shape memory alloy whose shape is memorized so that the spring constant is small when the spring constant is small and the spring constant is thick when the spring constant is larger than a predetermined set value.
