摘要： The arrangement for mounting a sparkplug of an internal combustion engine includes mounting the sparkplug so that all of the outside electrodes are arranged at an intake port side area and/or an exhaust port side area. Alternatively, in the case where at least one of the outside electrodes is located outside of the above-mentioned areas, no other remaining outside electrodes are arranged at a position that faces that outside electrode across the central electrode.

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： To provide a four-cycle engine, in which a pair of intake valve ports is openable/closable by respective intake valves and a pair of exhaust valve ports is openable/closable by respective exhaust valves. The pair of intake valve ports and the pair of exhaust valve ports are provided in a cylinder head such that they are positioned on both sides of a first virtual plane which contains the axial line of the cylinder bore and passes through an approximately central portion of the combustion chamber. A pair of ignition plugs is mounted in the cylinder head. The pair of ignition plugs is mounted such that the degradation of a flame propagation condition is minimized, even if accidental firing of either of the ignition plugs occurs. The pair of ignition plugs is disposed substantially symmetrically with respect to a second virtual plane which passes through the center of a combustion chamber and is perpendicular to the first virtual plane. The ignition plugs are mounted in the cylinder head such that they have axial lines extending substantially in parallel to the first virtual plane. The ignition plugs are tilted with a distance therebetween becoming smaller toward the combustion chamber. End portions of the ignition plugs, which project into the combustion chamber, are disposed in a region surrounded by the intake valve ports and the exhaust valve ports.

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： A plug hole pipe 79 has thread grooves 81 formed on an outer circumferential surface thereof and causes a spark plug 11 to be pressed against a cylinder head 51 when the plug hole pipe is fixedly attached to the cylinder head 51 through screw engagement. The spark plug 11 is configured such that no thread grooves are formed on the outer circumferential surface of a front end portion 25 of a metallic shell 19, and can be vertically inserted into a plug disposition hole 51a formed in the cylinder head 51. By vertically inserting the spark plug 11 into the plug disposition hole 51a while the orientation of a ground electrode 21 is set beforehand in relation to the cylinder head 51, the ground electrode 21 can be oriented in a specific direction.

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.
摘要翻译：在用于内燃机的点火装置中，包括用于在中心电极和接地电极之间进行放电的火花塞和具有用于向火花塞提供高电压的初级绕组和次级绕组的点火线圈在其中缠绕有一次和二次绕组的陶瓷卷轴中形成切口部分，并且突起部分形成在其中结合有连接器端子的绝缘树脂制保持构件中，突出部分与凹口接合部分。突出部分和切口部分的接合防止连接器端子在端子连接工作期间相对于陶瓷阀芯在陶瓷阀芯的圆周方向上移动。这解决了在使用陶瓷阀芯的情况下，由于在将连接器端子嵌入成型在陶瓷阀芯中时遇到困难，连接器端子可以在端子连接工作期间相对于陶瓷阀芯移动，绕组与连接器端子的连接导致端子连接的可操作性差。

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 ignition coil assembly of the type which is directly mounted onto an associated internal combustion engine spark plug. The coil assembly includes a spark plug boot section made of a highly elastic material with an inside cylindrical passageway. The inside passageway features ribs which engage a high voltage connection coil spring positioned in the passageway to make an electrical connection between the coil and spark plug high voltage terminals. The spring has a generally constant outside diameter outer section except its end segments have a reduced diameter where they contact the high voltage terminals. The passageway ribs retain the spring in position prior to its installation and after its removal from the associated spark plug.

摘要： A retaining apparatus for mounting a component in an aperture formed in a mounting surface includes an elongated base member having opposite ends. At least two generally parallel side members each extend from an associated one of said base member ends. Each side member includes a free end. A component having a flange with at least two slots formed therein receives an associated side member in each of the slots. A locking means extends from said side members adjacent said free ends. As the component is inserted in the mounting surface aperture, force is applied to move the free ends of the side members toward each other to permit the locking means to pass through the aperture in the mounting surface. When the force is removed, the locking means and the flange engage opposite sides of the mounting surface to releasably retain the component in the aperture.
