What is the calorific value of spark plug?

The calorific value is expressed by numbers, and the number in the middle of the general model is calorific value, and the units of different manufacturers are different. The calorific value of different brands is different, and the calorific value of each brand will have its corresponding model, which is applicable. For example, the calorific value of LDHRIK 16 is 6, and that of LDHRIKL is 7.

The calorific value of spark plug actually refers to an index of heating and heat dissipation ability, and the heat emitted by itself is called calorific value. The calorific value includes nine numbers: 1 ~ 9, where 1-3 is low calorific value, 4-6 is medium calorific value and 7-9 is high calorific value.

Cold spark plug: The spark plug of the original factory accessories generally has three calorific values: 5, 6 and 7. What can emit a lot of heat is called a cold spark plug, which is also a high calorific value spark plug.

The insulation skirt ratio (high heat value) of cold spark plug is short, the heat dissipation path is short, and the heat dissipation ratio is high, which is not easy to cause the temperature of the center electrode to rise. The relatively small heat dissipation is called hot spark plug, that is, low calorific value spark plug.
