    • PURPOSE: An ignition plug for measuring ion current and a controlling method and control circuit therefor are provided to perform ignition and an ion current measurement with few number of parts and a simple structure. CONSTITUTION: In an ignition plug for measuring ion current in which a terminal for energizing for making ignition current (IGK) flow to a heater element(3) arranged on a combustion chamber side within an ignitor(2) is provided, the ignitor(2) is arranged on a plug housing and is insulated from the plug housing and the plug housing is electrically connected with an engine block (earth), a diode(15) is integrally incorporated between a series circuit constituted of the ignitor(2) and the heater element(3) and a main body(4) of the ignition plug or is arranged in the form of a module, within a terminal side area of the plug. Instead of the diode(15), a semi-conductor switch such as a MOSFET provided with a voltage evaluation circuit may be integrally incorporated or be arranged in the form of the module.
    • 目的:提供一种用于测量离子电流的火花塞及其控制方法和控制电路,用于执行点火和离子电流测量,零件数量少,结构简单。 构成:在用于测量离子电流的火花塞中,提供用于使点火电流(IGK)通电的端子流到布置在点火器(2)内的燃烧室侧的加热器元件(3)的点火器(2) )布置在插头壳体上并且与插头壳体绝缘,并且插头壳体与发动机块(接地)电连接,二极管(15)整体地结合在由点火器(2)和 加热器元件(3)和火花塞的主体(4),或者在插头的端子侧区域内以模块的形式布置。 代替二极管(15),诸如设置有电压评估电路的MOSFET的半导体开关可以整体地结合或以模块的形式布置。
