Abstract
An ignition system has a series-gap discharge-bulb through which a high voltage is supplied to a center electrode of an ignition plug. A short-circuit element is made of a material that reversibly deforms when it is heated to a predetermined temperature when an engine is operated in a steady state. The short-circuit element is electrically connected to the plug such that two discharging electrodes are short-circuited by the short-circuit element when the short-circuit element is heated to thermally deform. The discharging electrodes may be made of a reversibly deformable material so that the electrodes deform into contact with each other when they are heated to a predetermined temperature.
