ABSTRACT:
An ignition system for an internal combustion engine comprising a battery, an ignition coil having a primary and secondary winding, a variable impedance element whose impedance is temperature dependent coupled between the primary of the ignition coil and the battery, and a set of distributor points coupled between the primary and secondary windings of the ignition coil and ground. The variable impedance element prevents deterioration of the ignition efficiency as the temperature of the ignition coil goes up, and can also prevent the temperature of the ignition coil from raising to a point wherein the ignition coil is damaged.
