摘要： A glow sensor (10, 74, 78, 90) provides functions of both a diesel engine glow plug for aiding fuel ignition during starting and low temperature operation and an ion sensor for sensing engine combustion initiation and characteristics. Compact glow sensor components may be assembled directly in combination with an engine combustion chamber defining component, such as a cylinder head, to provide a combination in which separate housings or shells for the glow sensors are not needed. Thus, the glow sensor elements (32, 76, 80, 91) and insulation may be made larger to provide greater electrical resistance in the ion sensor electrical circuit and enhance the operation of the ion sensor function. Various forms of glow sensors may optionally be used in such a combination including, for example, metal sheath (48) type glow sensors with either isolated or non-isolated coils and ceramic rod (82) or flat plate (92) type glow sensors. Exemplary embodiments of glow sensor components mounted in a cylinder head are disclosed.

摘要翻译： 发光传感器（10,74,78,90）提供用于在启动和低温操作期间辅助燃料点火的柴油发动机预热塞和用于感测发动机燃烧启动和特性的离子传感器的功能。 紧凑型辉光传感器部件可以直接与发动机燃烧室限定部件（例如气缸盖）组合，以提供组合，其中不需要用于辉光传感器的分开的壳体或壳体。 因此，可以使辉光传感器元件（32,76,80,91）和绝缘体更大以在离子传感器电路中提供更大的电阻并且增强离子传感器功能的操作。 各种形式的辉光传感器可以可选地用于这样的组合中，包括例如具有隔离或非隔离线圈的金属护套（48）型辉光传感器和陶瓷棒（82）或平板（92）型辉光传感器。 公开了安装在气缸盖中的辉光传感器部件的示例性实施例。
