Claims

[Scope of utility model registration claim] Breaker play built into the distributor. Ignition timing control for an internal combustion engine equipped with a vacuum advance device in which the rotation of the engine is controlled by a diaphragm device that responds to engine suction negative pressure, and the ignition timing is gradually advanced as the engine load decreases. In the device, a stopper for regulating the maximum retard position of the rod is provided in the middle of the rod connecting the breaker plate and the diaphragm device, and this stopper is interlocked with an actuator that operates according to the warm-up temperature of the engine, An ignition timing control device for an internal combustion engine, characterized in that the maximum retardation amount after warming up is larger than before warming up.
