New dual-coil ignition system enters testing

BorgWarner Beru Systems is developing a new dual-coil ignition system that promises to improve the combustion process of IC engines and help reduce emissions. Similar to a plug top ignition coil, BorgWarner’s latest technology consists of two ignition coils inside a single housing, connected directly to the spark plug in each cylinder. Currently under testing and development with several OEMs around the world, the new ignition system reduces ignition delays, allows more accurate ignition timing at different engine speeds and loads, and offers the flexibility of single- or multi-spark modes.

“BorgWarner’s new dual-coil ignition system is a game-changing technology in the development of the ideal combustion process,” said Brady Ericson, president and general manager, BorgWarner Beru Systems. “This new technology allows the ignition system to adapt to the continuously changing conditions inside the combustion chamber, helping to achieve a leaner burn and enabling increased exhaust gas recirculation for improved performance and lower emissions.”

Compared with conventional ignition coils, BorgWarner says its new dual coil ignition technology provides a significantly shorter ignition delay and better combustion stability over the whole engine speed range, particularly during part-load and idle conditions. Integrated electronics manage the charging and discharging of the coils as well as setting variable ignition energy. The system can deliver a single extended spark or multiple sparks in succession. In addition, the new dual-coil ignition technology provides broad flexibility for transient ignition settings in cases where load or speed changes rapidly, even with high amounts of internal EGR. To meet market requirements, BorgWarner intends to offer the new ignition technology in 12-volt or 40- to 50-volt versions.
