BorgWarner Emissions Systems said it was producing multi-spark ignition coils at its plant in Muggendorf, Germany, for Daimler’s six- and eight cylinder engines used in the Mercedes-Benz C-, E- and S-Class.
Specially designed for petrol direct-injection (GDI) engines running stratified combustion, BorgWarner’s compact multi-spark ignition coil technology enlarges the ignition zone for more controlled and optimised combustion, improved fuel economy and reduced emissions.

Based on a conventional 14-volt coil, the multi-spark ignition coil features a bidirectional interface with an electronic control unit to precisely trigger multiple discharges and recharges within one millisecond to produce spark energy multiple times at short intervals.
Enlarging the ignition zone and generating multiple sparks extends the spark duration considerably to deliver optimal combustion, improved fuel economy, lower emissions, and it prevents misfires. The technology helps reduce emissions during cold starts and improves engine running under nearly any operating condition, the supplier claimed.
