摘要： A spark plug cap for facilitating the fitting/detaching operation of a spark plug with a built-in pressure sensor, and a method of easily fitting the spark plug with a built-in pressure sensor are provided. The spark plug cap is provided with a cylindrical part of glass-containing PBT, a grommet provided with a cable passing groove, and an ignition coil unit provided with a high voltage terminal. The cylindrical part includes a first engagement part engageable with a spark plug fastening tool on one end, a second engagement part of a metal material engageable with a hexagonal part of the spark plug with a built-in pressure sensor on the other hand, and a groove-shaped clamp part on the outer side surface. By engaging the hexagonal part with the second engagement part to attach the cylindrical part to the spark plug, holding a sensor output cable by the clamp part, and fitting and fastening the spark plug fastening tool in the first engagement part, the spark plug is fitted into an internal combustion engine.

摘要： A spark plug for venting excessive engine cylinder pressure may be either pressure or temperature activated. A vent passage is created in a conventional spark plug by drilling an air vent through the housing of a conventional spark plug to a point that experiences cylinder pressures. The air vent is then sealed with a mechanical element of known structural strength and temperature response. Upon the development of excessive engine temperature, cylinder pressure, or both, the sealing element gives way, generating an air passage from the combustion chamber to the atmosphere through which cylinder pressure is vented. By venting excessive pressure, the disastrous effects of detonation, hydrolock, and other deleterious engine conditions may be avoided. Prior to the failure of the seal, the spark plug functions identically to a conventional spark plug.

摘要： The spark plug has a top end portion of a main metal shell that is almost cylindrical on an outer circumferential face without having a plug attaching external thread screwed into the cylinder head. Further, the plug hole formed in the cylinder head has a top end counterpart corresponding to the top end portion of the main metal shell. And in the mounting structure of the spark plug into the cylinder head (plug hole), the clearance amount (&phgr;D−&phgr;d) satisfies a relation &phgr;D−&phgr;d≦0.15 (unit: mm) where the outer diameter of the top end portion of the main metal shell is &phgr;d and the hole diameter of the top end counterpart of the plug hole is &phgr;D.

摘要： A two-piece igniter includes an outer housing that includes a cylindrical member having an outer wall and an inner wall that defines a passage through the outer housing. The igniter further includes a plug member adapted to fit within the passage of the outer housing and that includes an axial electrode and an axially insulating insulator element encircling the axial electrode, the axial electrode having a first end for connection to an electric source and a second end for engagement within a combustion area. The igniter also includes a longitudinally extending biasing member positioned about the plug member. The plug member may be releasably coupled within the outer housing by inserting the plug member within the passage of the outer housing and by manipulating the plug member once inserted.
