What is the term for an ignition system that is energized only until flame is established?

The term for an ignition system that is energized only until flame is established is known as interrupted ignition. This type of ignition system operates by providing a spark or flame to ignite the fuel for a brief period. Once the flame is successfully established, the ignition source is turned off. This approach enhances safety by reducing the risk of fuel accumulation in the event that the flame goes out.

In contrast, continuous ignition systems would keep the ignition source running throughout the entire heating process, which can increase the risk of malfunctions or safety hazards. Intermittent ignition typically refers to systems that cycle on and off at intervals, but this can be less controlled compared to interrupted ignition, where the ignition is specifically timed to turn off after flame establishment. Automatic ignition generally refers to systems that have self-starting capabilities without manual intervention, but it may not specifically imply the temporary nature seen in interrupted ignition systems.
