摘要： A multi-gap spark ignition device to be installed in a spark ignition engine, is disclosed. The device comprises a metallic base member provided with a hole which forms one portion of the combustion chamber of the engine. Within the wall defining the hole, a high voltage electrode, a plurality of intermediate electrodes and an earth electrode are embedded at regular intervals so that each end of the electrodes project into the hole to form a plurality of spark gaps between the adjacent ends of the electrodes. Each of the intermediate electrodes is composed of an electrode member and an insulating member for covering one end of the electrode member, and is closely inserted into a groove formed in one end surface of the base member along the hole thereof at regular intervals. By making the stray electrostatic capacity between the base member and the opposed electrode member of each intermediate electrode larger than the electrostatic capacity between the adjacent electrode members, the required voltage can be maintained small irrespective of the number of the intermediate electrodes.

摘要： An ignition system for internal combustion engines of the type in which after the energizing current flow to the primary winding of an ignition coil has been interrupted and an ignition spark generating high voltage has been produced in the secondary winding, the primary winding is energized again to interrupt the ignition spark. The ignition spark is interrupted at around the TDC only when the engine is at high speed operating conditions and the deenergizing current in the primary winding is not interrupted in a moment but decreased gradually. Also, the ignition spark is interrupted only when the ignition spark is to continue beyond the top dead center.

摘要： An ignition system for the internal combustion engine comprising a high voltage circuit for generating a spark, having the primary and secondary windings. In response to a first signal, the current in the primary winding is cut off thereby to generate a high voltage at the secondary winding. In response to a subsequent second signal, the primary winding is shorted thereby to cut off the high voltage thus far generated in the secondary winding, thus properly regulating the duration of the spark generated.

摘要： An engine ignition system includes a throttle sensor for detecting the position of a throttle valve. A control circuit is responsive to the detected throttle signal as well as the signals from other negative pressure and engine rpm sensors to generate a spark plug discharge start signal and a discharge stop signal. A high voltage generator supplies a high voltage to the respective spark plugs during the time interval between the time that the discharge start signal is generated and the time that the discharge stop signal is generated.

摘要： An ignition system for rotary piston engines includes a glow plug in addition to the normal leading spark plug and trailing spark plug. The glow plug is mounted in the housing of the engine on the leading side with respect to the trochoidal minor axis in the direction of the rotor rotation and performs continuous ignition of the mixture during low speed and load operation of the engine. Thus, during the low speed and load operation the glow plug performs ignition in place of the leading spark plug whereas during other engine operating conditions the leading spark plug and the trailing spark plug perform the ignition of the mixture.
