Ignition Technologies

BorgWarner is one of the leading suppliers in the field of ignition technologies for gasoline and diesel engines, increasing fuel efficiency, and performance while reducing emissions with fast-to-market solutions. For the gasoline market, the full range of ignition coil technologies including latest high energy ignition coils is available. For diesel engines, we deliver glow plugs, glow plug control units and entire cold-start systems combining the two.

High Energy Ignition Coils

BorgWarner’s compact plug top ignition coils facilitate optimal gasoline combustion through high ignition voltages and extended spark duration. With their excellent lifetime performance and compact design, they lower emissions, enhance engine performance and increase fuel efficiency.

Ignition Coil

Ignition Coil


  • High energy output of 60 to 100 mJ and high ignition voltage of 35 to 40 kV
  • Long lifetime: 15 years or 300,000 km
  • Fully encapsulated, water-protected design


  • More ignition energy and higher voltage than conventional plug top coils
  • New synthetic materials to reduce weight
  • Innovative, secure component connection technology to improve reliability and durability
  • Compact, space-saving and modular design
  • Electronics for ignition coil controlling can be integrated into its housing or the engine control unit
  • Modular construction offers on-demand customization e.g. energy output to be adjusted according to customer specifications

Coupled Multi-charge Ignition Coils

Designed for the challenging engine operating conditions in GDi vehicles, coupled multi-charge ignition coil fires multiple times, in quick succession with programmable spark duration. By increasing both spark duration and spark energy, it ignites the fuel mixture at just the right time, for optimum combustion.

Coupled Multi Charge Range


  • Programmable spark duration enables advanced, high efficiency combustion modes with difficult-to-ignite mixtures
  • Programmable control adapts delivered energy for robust ignition without excessive spark plug erosion


  • Microcontroller-based electronics with fast development and excellent ignition control flexibility compared to ASIC-based designs
  • Capable of high kV outputs at low and high energy delivery
  • Electronics for ignition coil controlling can be integrated into its housing or the engine control unit

Diesel Cold-Start Technologies

With solutions like the Instant Start System (ISS) featuring state-of-the-art glow plug control units and metal or ceramic glow plugs, BorgWarner’s diesel cold-start systems optimize the comfort and reliability of engine start-up. In addition, our sophisticated technologies minimize fuel consumption and emissions of diesel engines while improving performance and responsiveness.
