する内燃機関の点火進角装置。The negative pressure at the first negative pressure outlet, which is located slightly upstream from the closed position of the throttle valve in the intake air pipe and whose negative pressure changes depending on the opening degree of the throttle valve, and the second negative pressure outlet located downstream from the throttle valve. In an ignition advance device for an internal combustion engine that performs ignition advance control by operating an advance actuator using a composite negative pressure with a negative pressure at an outlet, one end is connected to the second negative pressure outlet and the advance actuator. A solenoid valve for opening and closing the negative pressure pipe is provided in the middle of the negative pressure pipe, the other end of which is connected to the negative pressure pipe connected to the first negative pressure outlet. The internal combustion engine is characterized by being provided with a solenoid valve control circuit that determines whether or not the engine speed is below a specified speed and issues a command to close the solenoid valve when the engine speed during idling falls below the specified speed. Engine ignition advance device.
