    摘要： The invention concerns a glow plug comprising a heating rod (11), a plug body (13), a mounting device (48) for mounting the heating rod, permitting axial translation movements of the heating rod relative to the plug body, a load sensor (17, 67) which is interposed between the heating rod and the plug body, and an electrical link, called the sensor link (71), which includes at least one signal line (74). The sensor link includes an earth conductive layer (82) which is interposed radially between said electrical power supply link of the heating rod and each signal line, to form a screening.

    摘要： A combustion pressure sensor (1) for an internal combustion engine is provided. The sensor includes a sensing element such as a piezoelectric device (122) sensitive to a physical load applied thereto to produce an electric signal indicative thereof and a bendable member (121). The bendable member is bent upon application of the combustion pressure in the engine to apply the physical load to the sensing element. Specifically, the physical load is applied to the sensing element which arises from the bend deformation of the bendable member, thus eliminating the need for a complete surface-to-surface contact between the sensing element and the bendable member. This results in a decreased unit-to-unit variation in sensitivity of combustion pressure sensors and ensures the stability of output characteristics of the combustion pressure sensor.

    摘要： The present invention provides a glow plug with combustion pressure sensor (100) having a plug body (220) having a screw portion (201a) on the outer peripheral surface that is inserted into a screw hole (1b) of an engine head (1) and screw-connected to it, a combustion pressure sensor (31) fixed to the plug body (220) to which the plug body (220) is inserted, and a lead wire (500) for leading out the sensor signal connected to the sensor (31), wherein the outside diameter of a hexagonal portion (221) used for screw connection between the plug body (220) and the screw hole (1b) out of the plug body (220) is smaller than the inside diameter of a through hole (31a) of the combustion pressure sensor (31) so that the plug body (220) can be inserted into the combustion pressure sensor (31) from the hexagonal portion (221) end.
