Delphi Product & Service Solutions is introducing 12 new ignition coils that cover over 2.9 million vehicles including BMW, Jeep, Mercedes-Benz, Volkswagen and Subaru applications from 1991 to 2012. Inventory will be available in the Q3 2014.
Ignition coils operate in a tough environment, notes Delphi. Stresses created by vibration, temperature changes, and even the failure of spark plugs and other components can cause ignition coil wiring to break or short out. The insulation inside the ignition coil can also fail, causing energy to escape.
Delphi ignition coils are manufactured with a winding process technique to control the length of wire between adjacent windings. That’s important because more length results in greater voltage differences, which can create more pressure that could break down the insulation and wire coating.
The high quality wires and wire coating resists the cracks, pin holes and imperfections that most often lead to failure issues. The company also uses an epoxy vacuum technique to reduce air bubbles in the epoxy, because having fewer air bubbles increases the epoxy’s insulating quality and reduces the chances of energy punch-through failures.
