摘要:
An ignition coil for an internal combustion engine has a housing composed of an insulating material and having an insertion opening, at least one ring-shaped core composed of a soft magnetic material and having a portion insertable in the housing, a primary coil body and a secondary coil body, a primary coil and a secondary coil wound on the primary coil body and the secondary coil body and arranged coaxially to one another on the portion of the core, the housing being provided with a high voltage dome extending substantially perpendicularly to a central axis of the coil bodies, a connecting pin insertable along a longitudinal axis of the high voltage dome and connected via a diode with a high voltage winding end of the secondary coil. The connecting pin, the diode and the coil bodies with the coils together form an operationally premounted assembly insertable through the insertion opening in the housing. A spacer connected with one of the coil bodies. The housing completely surrounds the core. The connecting pin and the diode is received in the spacer, the diode is arranged coaxially to the longitudinal axis of the high voltage dome.

An ignition system is described, in particular for an internal combustion engine of a motor vehicle, having a laser spark plug, a pump module for supplying the laser spark plug with pump radiation, and an optical fiber device for transmitting the pump radiation from the pump module to the laser spark plug. At least two separate signal transmission devices which each extend at least partially along the optical fiber device, and an evaluation unit, which is designed to act on each of the signal transmission devices with a test signal, to evaluate a response signal of the signal transmission devices which results from the particular test signal, and from the response signal to deduce an operating state of the corresponding signal transmission device, are provided.

A bar coil for use as an ignition coil in internal combustion engines (of motor vehicles) is designed so that casting resin can be introduced into an interior space of the bar coil in a manner that is advantageous from a manufacturing standpoint. The bar coil has a centrally arranged channel that extends from a connecting segment, through a core of the bar coil, and to a pan-shaped bottom area of the interior space of the bar coil. Casting resin flowing through the channel enters the closed bottom area, from which it is diverted as a uniform front to flow through gaps in the bar coil to the connecting segment.
摘要:
A cooling device for a laser spark plug. The cooling has a radially inner first contact area which is developed to establish a thermal contact to a housing of the laser spark plug via at least one first radially inner contact surface. The cooling device also has a radially outer second contact area which is developed to establish a thermal contact to a heat sink, in particular to an inner wall of a spark plug hole receiving the laser spark plug, via at least one first radially outer contact surface. A connector is provided, which is developed to establish a thermal contact between the first contact area and the second contact area. The cooling device is developed at least in part elastically in order to allow for a relative movement in a generally radial direction between at least the first contact surface and the second contact surface.
摘要:
A laser spark plug configured to be installed into a plug shaft of an internal combustion engine, and to focus laser ignition energy into the combustion chamber via combustion chamber-side, and thus proximal end, of the laser spark plug has, at a distal end of the laser spark plug opposite to the proximal end, a connecting unit for detachable mechanical and thermal connection to a cooler, the connecting unit being designed to permit the connecting and the disconnecting of the cooler when the laser spark plug is installed in the plug shaft.

The fastening arrangement for electrical connection to an ignition coil includes a housing; an epoxy resin circuit board in the housing and having a plurality of conductor paths electrically insulated from each other, each of which are provided with at least two ends having a bore hole for electrical connection to the primary windings; and a connection plug including elements for easily securing it to the housing and a plurality of electrical contacts extending from an exterior side of the plug and into the housing on an interior side. The housing is provided with a recess to accommodate the connection plug and a guide groove in the recess in which a projecting guide element of an outer peripheral flange of the connecting plug is pressed to fix the connection plug to the housing. The electrical contacts are electrically insulated from each other and each of them includes a pin on its interior end. The pins of the electrical contacts project through respective bore holes in the conductor paths and are soldered with the respective conductor paths so that the connection plug and the printed circuit board form a primary plug unit for making electrical connection to the ignition coil.
