特徴とする内燃機関の点火時期制御装置。 In an ignition timing control device for an internal combustion engine including a negative pressure advance device controlled by negative pressure from a negative pressure outlet of a carburetor or an intake pipe, the negative pressure advance device is connected to the negative pressure advance device. A temperature-sensitive on-off valve that senses the engine temperature and closes when the temperature is low, a one-way valve, and an orifice are provided in parallel in the negative pressure passage between the two, and the negative pressure advance is controlled when the negative pressure at the negative pressure outlet decreases. An ignition timing control device for an internal combustion engine, characterized in that a one-way delay valve is provided in parallel to delay a decrease in negative pressure within the device.
