摘要： A discharge device of the present invention including a pair of electrodes opposingly disposed in a sealed tube is characterized by the provision of a conductive member surrounding one of the electrodes in the sealed tube. An ignition system with a series gap has a built-in discharge device provided with a series gap, with one end connected to the center electrode side of the spark plug and with the other end connected to the high-tension cable side extending from the high-voltage distribution side. In this ignition system, a discharge device has a conductive member which surrounds one of the electrodes of the sealed tube, and one of the electrodes enclosed with the conductive member of this discharge device works as a cathode. Furthermore, in this ignition system with a series gap which includes a discharge tube provided with the series gap with one end connected to the center electrode side of the spark plug and the other end connected to the high-tension cable extending from the high-voltage distribution side, there is provided a conductive member enclosing the cathode side of the discharge device to be installed in the casing.

摘要： Only one pre-gap is arranged between the ignition coil and the distributor so that it is connected in series with each of the ignition plugs in the engine. A relay device is connected in parallel with the pre-gap. The relay device is normally closed to supply a high voltage from the ignition coil to the distributor, bypassing the pre-gap. Only when sensor signals indicate that the air-fuel combustion state is bad, the relay device is opened to cause the high voltage from the ignition coil to be applied to the pre-gap before being supplied to the distributor. This construction permits the single pre-gap to serve all the cylinders in the engine and prolongs the working life of the pre-gap.
摘要翻译： 在点火线圈和分配器之间仅设置一个预间隙，使得其与发动机中的每个点火塞串联连接。 中继装置与前置间隙并联连接。 继电器装置通常是闭合的，以便绕过预制间隙从点火线圈向分配器提供高电压。 只有当传感器信号表明空气燃料燃烧状态不良时，继电器装置打开才能使点火线圈的高电压施加到预压间隙上，然后供给分配器。 这种结构允许单个间隙为发动机中的所有气缸提供服务，并延长了前隙的使用寿命。

摘要： The discharge tube consists of an electrically insulating cylindrical body and a pair of electrodes disposed facing each other in the cylindrical body, and is sealed with an inert gas. An activation layer of a silicate compound of alkaline metal is formed over at least a part of the inner wall surface and the electrode surface, other than the discharge surface, that are exposed to the sealed gas. This activation layer helps keep the discharge inception voltage stable even when the discharge frequency changes greatly, which in turn extends the longevity of the discharge tube.

摘要： 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.
