Essentially the operating principle is the same for all types of ignition coils– whether the classic can-type coil, or in a coil rail system. The device contains two copper wire windings and a laminated iron core. The copper wires are insulated to prevent short circuits. The battery current fed through the primary winding produces a magnetic field whose strength is further increased by the iron core. When this circuit is opened, the magnetic field collapses, inducing a high voltage pulse in the secondary coil.
U3 Type Ignition Coil
The number of ignition cables corresponds to the number of spark plugs. The Ngk ignition coil of the Type U3 is a block ignition coil with two high-voltage outlets. It simultaneously supplies two spark plugs with high voltage through one ignition cable each (double spark technology).
