Davis, J A

This patent describes an ignition system for an internal combustion engine, consisting a cylinder having an end enclosed by a head, the head having at least three openings therein, the axes of the openings being at an angle to each other, a group of spark plugs, each spark plug being mounted in one of the openings, each spark plug having a single electrode with the inner end of each electrode disposed within the cylinder, an electrically conductive member extending laterally from the inner end of each electrode. The periphery of each member is spaced proximate relation to the periphery of adjacent members to provide a spark gap therebetween. The electrode of a first spark plug of the group is connected to the ignition coil of an engine, and the electrode of the last spark plug of the group is connected to ground. The electrode of an intermediate spark plug is capacitively loaded in the group.
