What is the approx. temperature at the spark plug at the time
of ignition??

Answer Posted / bikram sekhon

Whether a spark plug is installed in a lawn mower, boat,
truck, or race car, the plug tip temperature must remain
between 450° C and 850° C. If the tip temperature is below
450°C, the insulator area surrounding the center electrode
will not be hot enough to burn off carbon and combustion
chamber deposits. These deposits will accumulate and foul
the plug gap, leading to a misfire. When the tip temperature
exceeds 850°C, the ceramic around the tip will blister and
the electrodes will melt. Preignition and detonation caused
by the overheated tip are likely to cause engine damage.
The borderline between the fouling and operating regions
(450°C) is called the spark plug self-cleaning region. This
is the temperature at which the accumulated deposits burn
off of the center insulator. A function of temperature only,
the self-cleaning region has no relationship to spark
quality or intensity.
