ABSTRACT:
An ignition system for a gasoline engine comprising an ignition coil to which an electric current is supplied from a battery through a transistor. The transistor is so controlled as to turn on and off in response to switching off and on of a contact breaker. A current flowing through the breaker points of the contact breaker is increased temporarily in accordance with the operating conditions of the engine for preventing fouling or damage of the breaker points due to contaminants deposited thereon.
