1. A machine, comprising:
- a natural gas engine;
an ignition system; and
one or more processors configured to;
cause a first current to be provided to a coil of the ignition system,wherein the first current is configured to cause a first voltage that does not satisfy a threshold voltage to cause a spark in a spark plug of the ignition system; and
cause, after a gap period, a second current to be provided to the coil of the ignition system to cause the spark in the spark plug of the ignition system,wherein the gap period is configured to cause a resonant effect on the first voltage,wherein the second current is configured to cause a second voltage that satisfies the threshold voltage based on the resonant effect on the first voltage.

Abstract
A device may determine a timing configuration for an ignition system. The device may pulse a driver to apply a set of resonant voltage pulses to the ignition system. The set of resonant voltage pulses may cause a set of increasing peak voltages. At least one peak voltage, of the set of increasing peak voltages, may satisfy a threshold to cause a spark in a spark plug of the ignition system.
