摘要：In the standard of spark plugs, the calorific value is usually used to characterize the thermal characteristics of spark plugs.
In the standard of spark plugs, the calorific value is usually used to characterize the thermal characteristics of spark plugs. The calorific value of spark plugs represents the balance ability of the insulation skirt of the spark plug to absorb and dissipate heat, with higher calorific values. The stronger the balance between heat absorption and dissipation, the lower the calorific value of hot spark plugs and the higher the calorific value of cold spark plugs. Generally, engines with high power and high compression ratios use cold spark plugs with high calorific value; On the contrary, engines with low power and low compression ratios use low calorific value thermal spark plugs. The selection of spark plugs is generally determined by the factory through product shaping experiments and should not be replaced arbitrarily.
