Ignition Coils

Although the fundamentals of an ignition coil have not changed, the demands placed onthem have. Tighter emissions regulations, less engine space and requirements for better fuel economy and higher ignition voltage – up to 45,000 volts in modern cars - means that coil technology is constantly evolving. As a leading  OE manufacturer, Delphi has been at the forefront of many of these changes. With more than 100 years of OE ignition system expertise, we’ve created advanced magnetic design and modelling capabilities that are second to none. The result, an efficient coil design that delivers optimum engine performance, exhaust emissions and fuel economy.

Optimum wire length

More wire generates differences in voltage, and in turn extra pressure, that can cause the breakdown of insulation and wire coatings. So, we tightly control the length of wire between adjacent primary and secondary windings. The result? Our secondary winding is thinner and much longer than the primary in order to get the output needed for the voltage to jump the spark plug gap.

Smart processes

Ignition coil windings should also be evenly distributed and neatly wrapped. That’s why we wind both primary and secondary coils as smoothly and tightly as possible, directly onto a proprietary steel core. This approach helps to ensure maximum magnetic power in every turn of the wire. We also wind our secondary coils into more bays than many of our competitors for more consistent voltage distribution and reliable coil performance.

High quality components

We only ever use high-quality wires, and coating that resists the cracks, pin holes and imperfections that might cause other ignition coils to fail. A special Epoxy helps insulate these wires and keeps them separated. Gaps in the epoxy can reduce the integrity of the insulation, so we also employ a special vacuum technique to remove air bubbles and imperfections, and help prevent internal arching and shorts.

Resource Highlights

In this article, we discuss Delphi’ OE multi-charge ignition coils.

With shorter intervals between injection and ignition, coupled with leaner air fuel mixtures, today’s advanced gasoline direct injection (GDi) engines place greater demands on the ignition system. Making it the perfect time to launch our new OE multi-charge ignition coil technology.

Designed for the challenging engine operating conditions in GDi vehicles, Delphi' multi-charge ignition coil fires multiple times, in quick succession. By increasing both spark duration and spark energy, it ignites the fuel mixture at just the right time, for optimum combustion. This enables spray guided GDi engines to achieve up to 20 percent better fuel economy and reduced emissions, versus competitor time-controlled multi spark ignition systems. It also helps to limit emissions under cold-start conditions, by ensuring complete combustion of the fuel in the cylinder. No wonder the world’s leading vehicle manufacturers are fitting Delphi as OE!

But what about the aftermarket? Well here’s the good news! With our new ignition coils for Mercedes Benz and Nissan, you and your customers can now enjoy a high-quality repair, too. And with over 14 million coils, already fitted as OE to popular applications including Mercedes A220, C180, C200, E200, GLA200, Vito and Nissan Q50, Q60, plus future OE business through to 2028, you'll be seeing plenty of these vehicles on your ramps for repair in the coming years. So, whether you’re a distributor or garage, give your sales a little extra spark with Delphi’ super-fast, multi-charge ignition coils.
