NON-EQUILIBRIUM PLASMA DISCHARGE TYPE IGNITION DEVICE
摘要：
An ignition device performs spark ignition to a fuel mixture in a combustion chamber (13) of an internal combustion engine (100, 101) by using a spark plug (50). The spark plug (50) comprises a first electrode (51), a second electrode (52, 11a, 11b, 21), and an insulating member (53, 11c) which is formed from dielectric substance and interposed between the first electrode (51) and the second electrode (52, 11a, 21). By impressing an alternating current between the first electrode (51) and the second electrode (52, 11a, 21), non-equilibrium plasma discharge between the insulating member (53, 11e) and one of the first electrode (51) and the second electrode (52, 11a, 21) is promoted. Igniting the fuel mixture by the non-equilibrium plasma discharge achieves a high ignition performance is achieved with low energy consumption.
摘要（中）：

点火装置通过使用火花塞（50）对内燃机（100,101）的燃烧室（13）内的燃料混合物进行火花点火。 火花塞（50）包括第一电极（51），第二电极（52,11a，11b，21）和绝缘构件（53,11c），绝缘构件（53,11c）由介电材料形成并插入在第一电极 ）和第二电极（52,11a，21）。 通过在第一电极（51）和第二电极（52a）之间施加交流电流，绝缘构件（53,11e）与第一电极（51）和第二电极（51）中的一个之间的非平衡等离子体放电 电极（52,11a，21）被促进。 通过非平衡等离子体放电点火燃料混合物实现了高能量消耗的点火性能。
