摘要： A plug boot contains an ignition cable which is fitted with the stud terminal of a spark plug extending from an engine cylinder block. This plug boot is covered with a heat shield, and further with an auxiliary heat shield. The cylinder-side end portion of the auxiliary heat shield is fixed between the spark plug and the cylinder block. The cable-side end portion of the auxiliary heat shield is provided with a lid unit. This lid unit includes a fixing retaining member and a pressing portion. The fixing retaining member fits the lid unit to the auxiliary heat shield, while the pressing portion exerts downward forces on the plug boot. By the combination of fitting forces and downward forces, the ignition cable and the spark plug are reliably connected.

摘要： To permit adjustment of the combination sparkplug-optical sensor for heat transfer upon operation of the sensor-sparkplug combination as a sparkplug, in accordance with known sparkplug technology, the insulator of the sparkplug is formed with a central opening in which a material is included which is electrically conductive and providing for controlled heat transfer, for example a packing or a mixture of aluminum oxide with a conductive powder, such as graphite, aluminum, or copper; or, alternatively, sheet metal elements may be located therein providing controlled radial engagement around a central glass rod forming the optical sensor and the inner wall of the opening and the insulator (FIG. 2); or, alternatively, axially resilient elements, such as a bellows-like corrugated metal element (FIG. 3) or a stack of spring disks (FIG. 4) may be positioned in the opening, axially biased by screwing the connecting terminal (10) into a tapped opening of the insulator. Heat transfer or transmission control is effected by introducing between metallic components of the combination and the glass rod a heat conductive mass (2) which fills the space between the glass rod and the metallic components over a predetermined length, in accordance with desired heat transfer characteristics.

摘要： A spark plug for internal combustion engines wherein heat range is controlled by body configuration and the dissipation of heat through an extended nose portion of the body that extends beyond the ''''reach'''' to protectively enclose an extended insulator and center electrode, and that is exposed within the combustion chamber with the spark gap positioned at the ''''eye'''' of combustion and/or at an optimum ignition point. The heat range of the spark plug is efficiently controlled by means of the exposure and the fineness ratio of the extended nose portion of the spark plug body and heat transferred therefrom through threaded engagement that is of assured tightness adjacent the combustion chamber.
