An air passage 3 equipped with a regulating valve 4 that operates according to temperature so as to reduce the effective area of the passage as the temperature rises is provided in the intake passage 1, bypassing the throttle valve 2. In addition, an auxiliary negative pressure passage 12 is provided in the negative pressure passage 5 that opens into the intake passage 1 slightly upstream of the idle position of the throttle valve 2 and is connected to the negative pressure advance device A. The auxiliary negative pressure passage 12 connects the negative pressure passage 5 to a portion of the air passage 3 between the regulating valve 4 and the fixed throttle 11 provided upstream thereof, and also maintains a temperature below the set temperature. An ignition timing control device for an engine. 2. An air passage 3 is provided in the intake passage 1, bypassing the throttle valve 2, and is provided with a regulating valve 4 that operates according to the temperature so as to reduce the effective area of the passage as the temperature rises, and the air passage 3 is provided in the intake passage 1, bypassing the throttle valve 2. An auxiliary negative pressure passage 21 is provided in the negative pressure passage 5 that opens into the intake passage 1 slightly upstream of the idle position of No. 2 and is connected to the negative pressure advance device A; a control valve 19 which connects the negative pressure passage 5 to the downstream side of the throttle valve 1 of the intake passage 1 and which works in conjunction with the adjustment valve 4 to reduce the effective area of the passage as the temperature rises;
An engine ignition timing control device.
