ABSTRACT:
The invention relates to a method of engine control, which comprises firing a weak spark through the spark gap, measuring the current through or voltage across the electrodes following the weak spark, analyzing the voltage or current to derive a prediction of the flame propagation speed and subsequently firing a stronger spark through the spark gap to ignite the charge, the timing of the stronger spark being varied in dependence upon the prediction of the flame propagation speed.
