Ignition timing control device for an internal combustion engine
A spark-advance mechanism for an internal combustion engine is operated by vacuum pressure in the engine intake manifold. A conduit connecting the spark-advance mechanism to the intake manifold includes a solenoid operated valve which is normally open, and which is closed by either of two switches c...

| description | A spark-advance mechanism for an internal combustion engine is operated by vacuum pressure in the engine intake manifold. A conduit connecting the spark-advance mechanism to the intake manifold includes a solenoid operated valve which is normally open, and which is closed by either of two switches connected in parallel. One of the switches is closed when the engine temperature is low, and the other is closed when the engine RPM is high. When the solenoid valve is energized by either or both switches to close the conduit, atmospheric air is bled through an orifice to cause slow advance of the spark timing. |
