Abstract
A powertrain, and a control method therefor, are provided, wherein ignition of a combustible charge in a combustion chamber of a controlled auto-ignition internal combustion engine equipped with in-cylinder fuel-injection and a spark ignition device is controlled. The method comprises generating a spark-discharge plasma channel between the electrodes of the spark ignition device, and igniting the combustible charge. The spark-discharge plasma channel is moved toward and entrained by the combustible charge, effective to advance phasing of controlled auto-ignition combustion.
