の二次空気制御装置。[Claims for Utility Model Registration] 1. A main combustion chamber, an auxiliary combustion chamber communicating with the main combustion chamber through a through hole, a main fuel supply device that supplies a lean air-fuel mixture to the main combustion chamber, and a main throttle valve. and a sub-intake system including a sub-fuel supply device for supplying a rich mixture to the sub-combustion chamber and a sub-throttle valve interlocked with the main throttle valve. a secondary air passage that introduces atmospheric air downstream of the sub-throttle valve in the system; a solenoid valve provided in the secondary air passage; and a sensor that detects the opening of the main throttle valve and outputs a detection valve opening signal. means for detecting an opening/closing speed of the main throttle valve based on the valve opening degree signal; and determining whether or not the opening/closing speed is smaller than a predetermined negative value; and a control means for opening the solenoid valve for a predetermined period of time from the time of the determination when the engine is determined to be in the deceleration state. Features a secondary air control device. 2. The determining means determines whether the opening/closing speed is greater than a positive predetermined value, and determines that the engine is in an accelerating state when the opening/closing speed is greater than the positive predetermined value, and the control means determines whether the opening/closing speed is greater than the positive predetermined value. A secondary air control device for an internal combustion engine with an auxiliary combustion chamber according to claim 1, which closes the solenoid valve when it is determined that the electromagnetic valve is in the above state. 3 The determining means determines whether the opening/closing speed is between the negative predetermined value and the positive predetermined value, and the opening/closing speed is between the negative predetermined value and the positive predetermined value. The control means determines that the engine is in the steady state and determines whether the value of the valve opening signal in the steady state is greater than or equal to a predetermined opening value; A secondary combustion engine for a sub-combustion internal combustion engine according to claim 1 or 2, wherein the solenoid valve is closed when the valve opening signal value is determined to be equal to or greater than the predetermined opening value. Air control device.
