System and method for ignition spark energy optimization

摘要

A method for controlling spark energy from a spark plug of a combustion engine. The method includes determining a spark energy intensity based on at least one engine operating condition, determining a period of time to supply current to an ignition coil connected to the spark plug to achieve the determined spark energy intensity from the spark plug as a function of a voltage supplied from a power supply to the ignition coil, and connecting the power supply to the ignition coil for the determined period of time.
