Abstract
An ignitor (10) for initiation combustion of fuel in an internal combustion engine includes a body portion (12) and a removable electrode portion (14) to permit replacement or repair of the electrodes, so that current is delivered to one of the electrodes (72) along a path through each of the capacitive elements. The body portion includes a pair of capacitive elements defined by longitudinally spaced, radially extending, annular capacitor plates (60, 62, 64, 66) which surround the central electrode (26, 72). The body portion includes an outer, cylindrical shell (16) which is insulated from the capacitive elements by layers (40, 42) of high dielectric material.
