の点火時期制御装置。 A double vacuum advance device is installed that has a main diaphragm and a sub diaphragm that are linked to the breaker plate of the distributor, and the main diaphragm chamber is communicated with the intake pipe on the downstream side of the throttle valve to advance the angle according to the engine suction negative pressure. On the other hand, a switching valve is provided to selectively communicate the sub-diaphragm chamber with the intake pipe and the atmosphere, and a means for detecting the engine cooling water temperature and a means for detecting the outside air temperature or the intake air temperature are provided. Based on the operating conditions, the cooling water temperature is lower than the first set value, the cooling water temperature is higher than the first set value, lower than the second set value, and the intake air temperature is lower than the set value. 1. An ignition timing control device for an internal combustion engine, comprising a control means for communicating an auxiliary diaphragm chamber with an intake pipe and advancing the ignition timing in accordance with engine suction negative pressure.
