ABSTRACT:
An ignition system for an internal combustion engine that provides automatically advanced timing over a predetermined range of engine speeds. The ignition system includes a timing circuit (100) that controls the resistance and hence voltage across a capacitor (53) that biases a switch in the trigger circuit (50) of the system. The transistor (125) is operated in its active region so that the transistor (125) operates as a variable resistor. As the resistance of the transistor (125) decreases with increasing engine speed the timing of the system advances. The predetermined speed at which the advance begins is determined by zener diode (119) in series with the base of the transistor (125). The maximum advance of the system is limited by a resistor (94) in series between the transistor (125) and the capacitor (53) of the trigger circuit (50). The transistor (125) is operated in its active region by a transistorized circuit that receives its power from the main storage capacitor (27) of the ignition system.
