摘要： PURPOSE:To improve firing capability and prevent a radio noise, by providing electrically insulated two electrodes to a combustion chamber of an internal- combustion engine and forming a spark gap for a spark discharge. CONSTITUTION:Electric discharge plugs 4 without having an earth electrode are provided to a cylinder head 6, and plus voltage is applied to one of the plugs while minus voltage is applied to the other plug to perform electric discharge in a a spark gap (h) and ignition of a mixture. Since a high voltage circuit used for these plugs is floated from a vehicle body, voltage at an electric discharge can be decreased to a half level and required insulation breakdown voltage of parts such as high tension cables, spark plugs 4, etc. can be halved. Further the plug 4, not having an earth electrode, is consumed in a few cases by overheat, and a sufficient thermal value can be ensured. In this way, firing capability is also improved and a radio noise can be also prevented.
摘要翻译：目的：通过向内燃机的燃烧室提供电绝缘的两个电极并形成用于火花放电的火花隙，以提高发射能力并防止无线电噪声。构成：将没有接地电极的放电插头4设置到气缸盖6，并且在向另一个插头施加负电压以在火花隙（h）和点燃混合物。由于用于这些插头的高电压电路是从车体浮出的，所以放电时的电压可以降低到一半，并且需要将高压电缆，火花塞4等部件的绝缘击穿电压减半。此外，不具有接地电极的插头4在几种情况下被过热消耗，并且可以确保足够的热值。这样，也可以提高发射能力，还可以防止无线电噪声。

摘要： PURPOSE:To prevent the occurrence of preignition as well as to improve the extent of heat resistance, by using a ceramic sintered body made of nitride as a cylinder head, while unifying an electrode material excellent in the heat resistance and the cylinder head at the time of sintering. CONSTITUTION:A cylinder head 1 consists of a nitriding silicon sintered body having high insulating and high thermal conductive properties. A shaft hole 1d composed of both an end side small diametral hole 1e and a terminal side large diametral hole 1f partitioned by a step part 1c to be reduced in diameter is made up on this combustion chamber inner surface 1a, and inside this shaft hole, a heat resisting positive electrode 2 provided with a discharge part 2a firmly coupled and projected to and from the combustion chamber inner surface 1a is installed. In addition, a negative electrode 3 opposite to the electrode 2 is coupled alike with the shaft hole 1d. Sintering for the cylinder head is carried out after both positive and negative electrodes 2 and 3 are formed up in advance. With this, not only preignition is prevented but also heat resistance is improved, say, a double purpose.
