Internal combustion engine with rail spark plugs and rail fuel injectors

An ignition transformer assembly for firing a spark plug of a spark ignition internal combustion engine, said transformer assembly having a multiple number of ignition transformers, each said transformer comprising:

• a. a substantially disk core having a pair of ends and constructed of a material having magnetic properties, said core having an axially central bore;
• b. a primary winding having ends, said primary winding wound about said core in a series of turns which extend longitudinally generally along an outer surface of said core, about one of said ends of said core, longitudinally generally along an inner surface of said core, and about the other of said ends of said core, said primary winding in series with other said primary windings of other said ignition transformer within said ignition transformer assembly;
• c. a secondary winding having ends, said secondary winding wound about said core in a series of turns which extend longitudinally generally along an outer surface of said core, about one of said ends of said core, longitudinally generally along an inner surface of said core, and about the other of said ends of said core, the number of said series of turns of said secondary winding is greater than said series of turns of said primary winding, and each said secondary winding has a separate high voltage isolated conductor that is isolated from every other secondary winding of every other said ignition transformer within said ignition transformer assembly, and has a common conductor that is connected to every secondary winding of every said ignition transformer within said ignition transformer assembly;
• d. a dielectric housing encasing said ignition transformers;
• e. a pair of terminals electrically connected to extreme ends of said primary windings of said ignition transformer assembly and adapted to be connected to an electrical power supply;
• f. a second set of terminals consisting of one central common terminal electrically connected to said common conductor of said secondary windings and multiple isolated terminals electrically connected to said isolated conductors of said secondary windings, one said isolated terminal for each said isolated conductor, and adapted to be coupled to the terminals of a multi-terminal spark plug or railplug.
