Indirectly sensing switch current or voltage lets the igniter adjust over-dwell to battery conditions, preventing coil overheating and damage.
This ignition circuit bypasses the diode through a resistor or switch, dissipating residual voltage and protecting engine components.
A non-contact ignition control device uses a low-voltage trigger coil to activate switching elements for reliable engine operation.
A multi-coil ignition system adjusts dwell time and spark frequency to maintain stable combustion.
