Ignition distributor for internal combustion engines

The distributor comprises a rotatably mounted rotor, which has close to its axis of rotation a first electrode and has at its end that is remote from the axis of rotation a second electrode, which is connected by an electric line to the first electrode. The distributor also comprises a housing, which is closed by a cap, which is provided on its inside peripheral surface with a plurality of peripherally spaced apart fixed electrodes for cooperating with the second electrode of the roto. The cap is further provided on its inside surface with a center electrode, which terminates at a distance from the first electrode of the rotor to form a spark gap therewith. To form a positive joint with the cap the embedded portion of the center electrode has a non-cylindrical peripheral surface, which is rounded and free of any edge.

An ignition coil (1) for internal combustion engines comprises a magnetic core (4) of the core- of sleeve type, around the main core of which the primary and secondary winding being insulatingly enveloped with a cast material is arranged, the end regions of the main core being connected with each other via a magnetic path located outside the two windings, and having mounting members attached to the magnetic core (4) for mounting the ignition coil (1) to an automobile body. In order to bring the heating of the windings to an equal level and to reduce the heating of the windings, the mounting members are formed of a mounting plate (8) with mounting surface (9) and of at least one frame member (10, 11) integrally formed with the mounting plate (8) which envelopes the magnetic core (4) in a form-locking manner. The frame members (10, 11) can be expediently placed for mounting angularly on the ignition coil (1) and are pivotable in abutment with the surface of the magnetic core (4).

Ignition coil for internal combustion engines

A diagnostic apparatus, especially for measuring the ignition voltage development in motor vehicles, which is equipped with two measurement value pick-up devices whereby each pick-up device is constructed as adaptor plug while the two pick-up devices are movable relative to one another by means of a connecting member.
