Abstract
Methods and systems are provided for determining an ignition coil dwell time based on an estimated ignition coil temperature. In one example, a method may include estimating the ignition coil temperature based on heat transfer between engine and the ignition coil, heat transfer between ambient and the ignition coil, and internal resistive heating of the ignition coil.
