wait for ignition, typically 0.5 to 2 seconds; turn burner knob past lite position, to stop the sparking noise and burning out the ignition electrode, to a desired flame intensity; One implementation of a gas burner with auto reignition senses the electrical conductivity of the flame.
The autoignition temperature or self-ignition temperature, often called spontaneous ignition temperature or minimum ignition temperature (or shortly ignition temperature) and formerly also known as kindling point, of a substance is the lowest temperature at which it spontaneously ignites in a normal atmosphere without an external source of ignition, such as a flame or spark.

Originally the company specialized in ignition and electrical parts. [4] In 1920 Van Allen opened a Standard Motor Products branch in Seattle. In 1921 the company moved to the Long Island City section of Queens. The partnership dissolved in 1925 and in 1926 the company was incorporated with Fife as the sole proprietor.
The ignition source of a diesel engine is the heat generated by the compression of the air in the cylinder, rather than a spark as in gasoline engines. The dieseling phenomenon occurs not just because the compression ratio is sufficient to cause auto-ignition of the fuel, but also because a hot spot inside the cylinder (spark plug electrode ...
Homogeneous charge compression ignition (HCCI) is a form of internal combustion in which well-mixed fuel and oxidizer (typically air) are compressed to the point of auto-ignition. As in other forms of combustion , this exothermic reaction produces heat that can be transformed into work in a heat engine .
In spark-ignition internal combustion engines, knocking (also knock, detonation, spark knock, pinging or pinking) occurs when combustion of some of the air/fuel mixture in the cylinder does not result from propagation of the flame front ignited by the spark plug, but when one or more pockets of air/fuel mixture explode outside the envelope of the normal combustion front.
For spark-ignition engines the fuel has an octane rating. For diesel engines it depends on the type of fuel, for distillate fuels the cetane numbers are used. Cetane numbers are tested using a special test engine, however, the existing test engine was not intended for residual fuels.
