Similar to a plug top ignition coil, BorgWarner BERU’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, BorgWarner says the new ignition system reduces ignition delays and allows more accurate ignition timing at different engine speeds and loads, as well as offering the fl exibility of single- or multi-spark modes.
Integrated electronics manage the charging and discharging of the coils as well as setting variable ignition energy. BorgWarner intends to offer the new ignition technology in 12-volt or 40- to 50-volt versions.
