摘要： In an engine igniting coil device which is embedded in a cylinder bore of an engine and directly connected with an igniting plug therein, a coil case containing an igniting coil assembly is made of conductive magnetic material and held at the ground potential level, thus preventing a decrease of output factor of the igniting coil device due to an iron loss of a produced magnetic flux when spreading about and passing a cylinder head of the engine and eliminating the possibility of leakage discharge from a high-voltage portion of the igniting coil assembly to the coil case and the cylinder head.

摘要： The invention concerns an ignition coil arrangement for a multi-cylinder internal combustion engine having at least one coil unit (11) which is easy to mount even in confined installation conditions. To this end, the coil unit (11), which comprises a primary winding (12) and a secondary winding (14) which is connected to two spark plugs (13), is constructed such that it is divided and mechanically separate within the windings (12, 14). A primary partial winding (17) and an associated secondary partial winding (18) are in each case combined to form partial windings (21, 22) which are electrically connected in series via a primary connection line (24) and a secondary connection line (26), respectively, and can be controlled jointly via a switching element (16). The ignition coil arrangement is used in particular in motor vehicles.

摘要： An ignition coil intended for being mounted directly on a spark plug comprises a laminated magnetic core (30) of elongated shape along a longitudinal axis (31) of said coil, together with a low-voltage primary winding (20p) coaxial with the magnetic core (30) and arranged in such a manner as to generate magnetic flux lines substantially parallel to said longitudinal axis (31), and a high-voltage secondary winding (20s) likewise coaxial with the magnetic core (30) and arranged in such a manner as to interlink with said magnetic flux lines (44). The said core (30) comprises at least two sections (40a, 40b) in line with each other along its longitudinal axis (31) and axially separated, by a separation space (42) of nonmagnetic material.

摘要： To provide an ignition coil device in which only a damaged portion can be exchanged and which requires no connector for connecting a power switch with a wiring harness.
Since an ignition coil device 2 is constructed such that a primary coil portion 21 and a power switch 22 are secured by fitting the primary coil portion 21 into a hollow core of a secondary coil portion 23 mounted in advance on an engine 30, the primary and secondary coil portions 21, 23 can be detachably connected via an iron core 21c as a magnetic core. Accordingly, only the secondary coil portion 23 having a relatively short life due to the generation of varying high voltage can be easily exchanged. Further, since the power switch 22 and the primary coil portion 21 are integrally or unitarily connected with a wiring harness 40, the construction can be made inexpensive and simple by the deletion of a connector provided in a prior art ignition coil device, thereby enhancing electrical reliability.
摘要翻译：为了提供点火线圈装置，其中仅可以更换损坏的部分，并且不需要用于将电源开关与线束连接的连接器。由于点火线圈装置2被构造成通过将初级线圈部分21装配到预先安装在发动机30上的次级线圈部分23的中空芯中来固定初级线圈部分21和电源开关22，次级线圈部分21,23可以经由作为磁芯的铁芯21c可拆卸地连接。因此，只有由于产生变化的高电压而具有较短使用寿命的次级线圈部23才能够容易地更换。此外，由于电源开关22和初级线圈部分21与线束40整体或整体连接，所以通过删除现有技术的点火线圈装置中提供的连接器，可以使结构变得便宜和简单，从而增强电气可靠性。

摘要： A method for determining engine load of a spark ignition internal combustion engine. The method includes the steps of charging an ignition transformer to a maximum ignition charge and initiating an ignition discharge between electrodes of the spark plug. The ignition transformer is then charged to a predetermined diagnostic charge which is less than said maximum ignition charge. The diagnostic charge is discharged at a time of the combustion cycle where pressure in the combustion cylinder is dependent on engine load. The duration diagnostic discharge is then monitored and subsequently correlated to engine load. In this manner, the spark plug is used as a feedback element in determining engine load. Further also detection of misfire, autoignition and preignition. Use is made of special CPP ignition transformers which are able to refire at short intervals. Multispark ignition applied during hard engine operating conditions e.g. cold starting.
