The simultaneous ignition of all the burners can be provided by a gas burner component called a __________.

The simultaneous ignition of all the burners in a gas appliance is effectively facilitated by a component known as a crossover igniter. This device is designed to ensure that when one burner is ignited, the flame can easily jump across to ignite the adjacent burners, thereby allowing all burners to ignite at the same time. This is particularly important for ensuring an even distribution of heat and promoting efficient combustion in appliances like gas stoves and ovens.

In contrast, the other components mentioned do not serve the same specific function as a crossover igniter. A spark plug is utilized primarily in igniting fuel in internal combustion engines, a pilot light provides a standalone flame that ignites gas on demand but does not create simultaneous ignition across multiple burners, and an ignition coil is related more to supplying power for creating a spark in engines or certain ignition systems, rather than directly facilitating ignition for multiple burners in a gas appliance. Thus, the design and intent of a crossover igniter make it the most suitable choice for achieving simultaneous burner ignition.
