摘要： An insulator includes a coil side cylindrical portion extending from a plug side cylinder portion in a direction departing from a combustion chamber. One end of the coil side cylindrical portion protrudes in the direction departing from the combustion chamber with respect to a primary winding and a secondary winding. A pressure sensing element is disposed next to the one end of the coil side cylindrical portion. The signal lines of the pressure sensing element are taken out of a casing without passing aside an ignition coil. Thus, the diameter of the casing does not increase. The output signal of the pressure sensing element is not adversely influenced by discharge noises generated from the ignition coil.

摘要： An insulator includes a plug side cylindrical portion having an inner space for accommodating a center electrode and a coil side cylindrical portion extending in a direction departing from a combustion chamber. The high-voltage portion of an ignition coil is entirely accommodated inside the coil side cylindrical portion. According to this arrangement, the coil side cylindrical portion can assure insulation between the high-voltage portion and the low-voltage portion. The portion to be insulated and fixed by an insulating resin is limited only to the secondary winding.

摘要： An internal combustion engine ignition device has a resin layer in a clearance between an insulator and a winding contained in the insulator. The ignition device has a cylindrical insulator and a resin layer. The insulator has an opening portion at one end and a bottom portion at the other end. The insulator contains one of a primary winding and a secondary winding. The resin layer is formed by charging a resin in the clearance between the insulator and one of the windings. The diameter of the inner periphery of the insulator gradually increases from the opening portion to the bottom portion. When the resin layer shrinks from the opening portion toward the bottom portion of the insulator, the resin layer can shrink without getting snagged on the inner periphery of the insulator.

摘要： An inspection object constructed of an ignition plug and an ignition coil is inserted in an inspection housing that does not have a ground electrode. A voltage generated in the ignition coil is measured while the inspection object is housed in the inspection housing. Electrical discharge does not occur because the ground electrode is not provided. Therefore, the voltage generated in the ignition coil is properly measured for quality inspection of the ignition coil.

摘要： An ignition device for an internal combustion engine has a housing, which includes a first case adjacent to the combustion chamber of the engine and a second case away from the combustion chamber. The first case has a flange formed at its end away from the combustion chamber. The second case has a flange formed at its end adjacent to the combustion chamber. The first case flange faces the side of the second case flange that is away from the combustion chamber. A bolt is screwed into the second case to engage the flanges with each other, substantially integrating the cases with each other.

摘要： In an ignition device for use in an internal combustion engine in which a spark plug and an ignition coil are integrated with each other and mounted in a cylinder head, a case is made of an electrical conductive material and one end portion of a secondary winding of the ignition coil is electrically connected to a center electrode of the spark plug while the other end portion of the secondary winding and an earth electrode of the spark plug are electrically connected to the case. Thus, the low-voltage side of the secondary winding and the earth electrode are electrically connected to each other through the case. This eliminates the need for a connector terminal and a wire harness for the electrical connection of the low-voltage side of the secondary winding to the internal combustion engine.

摘要： In an ignition device for an internal combustion engine, comprising a spark plug made to carry out an electric discharge between an center electrode and an earth electrode and an ignition coil having a primary winding and a secondary winding for supplying a high voltage to the spark plug, notch portions are made in a ceramic spool on which one of the primary and secondary windings is wound and projecting portion are made in an insulating-resin-made holding member into which connector terminals are incorporated, with the projecting portions being engaged with the notch portions. The engagement of the projecting portions and the notch portions prevents the connector terminals from moving with respect to the ceramic spool in circumferential directions of the ceramic spool during terminal connection work. This solves the problems in that, in the case of the employment of a ceramic spool, because difficulty is encountered in insert-molding the connector terminals in the ceramic spool, the connector terminals can move with respect to the ceramic spool during terminal connection work for the connection of the winding to the connector terminals to cause poor terminal connection workability.

摘要： A combustion chamber pressure sensor for an internal combustion engine includes an elongated pressure transmitting member having one end exposed to the interior of an engine cylinder and the opposite end contacting a pressure sensing element which generates a pressure measurement signal, the pressure transmitting member and pressure sensing element being contained within an elongated housing. A damping body formed of a viscoelastic material is disposed on an outer or inner circumferential surface of the housing, for reducing an amount of engine vibration that is transmitted to the pressure sensing element and thereby reducing noise in the pressure measurement signal.
