角制御装置。In an ignition advance control device that operates a variable ignition advance member of a spark ignition internal combustion engine using a negative pressure responsive actuator to control the ignition advance, a first negative pressure opening in an intake passage downstream of an intake throttle valve is used. Intake negative pressure taken out from the intake port and intake throttle taken out from the second negative pressure takeout port that opens at the intake passage position on the downstream side of the intake throttle valve as the valve opening increases near the upstream of the intake throttle valve when fully closed. Negative pressure near the valve and near the intake throttle valve taken out from the third negative pressure outlet that opens at the intake passage position upstream of the intake throttle valve as the valve opening increases near the downstream of the intake throttle valve when fully open. An ignition advance control device for a spark ignition internal combustion engine, characterized in that a composite negative pressure of another negative pressure is introduced into a negative pressure working chamber of the actuator as a negative pressure signal.
