摘要:
A connecting means for ignition systems in internal combustion engines is designed such that the connecting means is functionally reliable even under unfavorable operating conditions. The connecting means has, among other things, a first connection for an ignition coil, a second connection for a spark plug, and a covering cap encasing these connections. The covering cap is made of two layers, having an inner casing made of electrically insulating material and an outer casing lying directly on the inner casing, the outer casing being made of an electrically conductive material, which is electrically connected to ground potential. The casings are each made up of a resilient material. The connecting means is for use in the automotive industry.

A rod coil (11) for ignition systems, in particular in the form of an ignition coil in internal combustion engines of motor vehicles, designed for long-term serviceability.The rod coil (11) has a centrally located core (14) as the internal magnetic iron core and, on a housing (13), a yoke (18) made of plastic as the external magnetic iron core. To avoid partial electrical discharges on the rod coil (11), a fill body (22) is provided between the yoke (18) and housing (13) thereby forming an inner, gap-free bond between the yoke (18) and housing (13).

An ignition device for gas discharge lamps is proposed, in particular for motor vehicle lights. The ignition device contains a first transformer (17) which is supplied on its primary side with an alternating current produced from a direct current supply voltage. To generate this alternating current, a capacitor (14), which is acted upon by a charging current, constitutes a closed circuit together with the primary winding of the first transformer and a spark gap (16), wherein the spark gap (16) arcs at a predetermined charge state of the capacitor (14). This device makes a simple, inexpensive, and space-saving device possible for generating the required operating voltage for the transformer (17), wherein the spark gap can be reliably used, even at higher temperatures.

To reliably provide ignition energy only to specific spark plugs (11, 12; 14, 15) of a multi-cylinder internal combustion engine (ICE), a double-E core has a main or common or central branch, and separate primary (6, 8) and secondary windings (10, 13) located in shunt core branches (18', 19'), each secondary winding being associated with respective spark plugs. The magnetic circuits of the primary windings including the common branch and single air gaps (20, 21), each in the shunt magnetic paths (18, 19), so that the flux change generated upon interruption of current flow through the respective primary windings need pass through one air gap only for the associated concentric secondary, buth through two magnetically serially placed air gaps for the other secondary.

An ignition device for an internal combustion engine occupies a small amount of space and is suited for efficient manufacturing. For this purpose, the ignition device has an ignition coil which is designed as a bar ignition coil having a coil former arranged concentrically to a longitudinal axis of the ignition coil, an insulation carrier being coaxially attached to the coil former. The coil former is provided with a winding set, the winding wire of which is continued to the insulation carrier. At this point, an interference suppression element in the form of an inductor is implemented in a continued winding. The ignition device is preferably utilized in motor vehicles.

An arrangement for mounting an ignition coil on the cylinder head of internal combustion engines. Threaded bolts extend from the cylinder head. The thread having a substantially saw tooth cross section with the thread flank facing away from the cylinder head at an acute angle and the thread flank head oriented substantially normal to the axis of the bolt. The ignition coil, which for this purpose is provided with a bore, may be slipped onto the bolt and a fastener provided with a resiliently expansible locking member may thereafter be slipped onto the bolt.

A coil is produced by wrapping a primary winding of the coil onto a core rod of a wrapping machine, arranging a secondary winding of the coil on a winding form and pushing it coaxially over the primary winding, pulling the core rod out of the primary winding, simultaneously inserting an iron core into the primary winding, and moving along a housing which accommodates the iron core onto the ignition coil, and filling the housing with casting resin to form a plastic block which surrounds at least the primary winding.

To reliably provide ignition energy only to specific spark plugs (11, 12; 14, 15) of a multi-cylinder internal combustion engine (ICE), a double-E core has primary windings (6, 8) located on a main or central branch, and separate secondary windings (10, 13) located in shunt branches, each secondary winding being associated with respective spark plugs. The primary windings are so energized that, at any one time, only one of the primary windings is conductive. In accordance with the invention, permanent-magnet biasing magnets (18, 20) are located in air gaps in the shunt magnetic paths (17, 19), and so polarized that the flux generated upon current flow through the respective branches of the primary windings is counter the bias magnetization of the respective magnet (18, 20) in the respective shunt path (17, 19) on which the secondary winding (10, 13) is wound which is associated with the respectively energized primary winding (e.g. primary 6-secondary 10; upon energization of primary winding 6, the flux will oppose the flux on magnet 18).

To improve the operating reliability and accuracy of ignition breaker contacts, an operating rod passes into a sealed housing, in gas-tight manner, by being secured, gas-tight, to a membrane which is resiliently deflectable, the breaker rod reciprocating under control of an engine operating cam, the membrane effecting a gas-tight seal while, by resilient deflection, transferring operating movement into the interior of the breaker switch housing; the breaker contacts are retained in the housing. A spring is used to provide for operating force, or the membrane may be pre-stressed; the interior of the housing may be evacuated or may contain a protective, inert gas.
