Abstract
A pre-ignition gap for coil ignition systems consists of a pair of electrodes which extend into a closed compartment. Each electrode has a free end within the compartment and the free ends of the electrodes are juxtaposed with and spaced from one another. A body of inert gas in the compartment surrounds the free ends of the electrodes. In the region of sparking, the electrodes are composed, at least in part, of a substance selected from the group consisting of aluminum and the transition metals of the fourth, fifth and sixth groups of the periodic system.
