Where are spark igniters located?

Explanation:
Spark igniters are placed at two ignition ports in the combustion liner so ignition happens reliably across operating conditions. These two ports are opposite each other around the liner, located in the primary combustion zone where the air–fuel mixture is hottest and most easily ignited. This symmetric placement ensures a strong, quick light-off and stable ignition no matter how the flow or swirl changes during different operating modes. If igniters were placed at other locations, ignition could be uneven or fail under certain conditions, which is why these two specific ports are used.
