4 , Calorie value

The spark plug acts as a terminal part of the engine ignition system and plays a vital role. The spark plug calorific value is the spark plug heat and cooling capacity of an indicator, its own heat dissipation is called calorific value.
Spark plug calorie value
Spark plug calorie value includes 1 to 9 nine figures, of which 1 - 3 for the low calorific value, 4 - 6 for the calorific value, 7 - 9 for the high calorific value. The original spare parts spark plug heat value is generally 5,6,7 three kinds, can be a lot of heat called cold spark plug, that is, high calorific value spark plug, cold spark plug (high calorific value) of the insulator skirt is relatively short, due to heat The way is relatively short, the heat is relatively more, so it is not easy to cause the center electrode temperature rise. Relative heat dissipation is called hot spark plug, that is, low calorific value spark plug.
Hot type spark plug (low calorific value) of the insulator skirt longer, when the cylinder temperature is arranged evenly, the longer the skirt, the greater the area of ​​heat, the longer the conduction heat distance, so less heat, the central electrode temperature rise high. In general, low calorific value of the spark plug is more suitable for low-speed low compression ratio of low-power engine, and high calorific value spark plug is suitable for high-speed high compression ratio of high-power engine. The smaller the value, the more the "cold", the smaller the value, the smaller the heat dissipation of the spark plug, the more "hot", the calorific value, depending on the cylinder mixture temperature and spark plug design.
Spark plug is a "cold type" or "hot type" directly determines its own cooling capacity, that is, the spark of the original heat value directly determines its working environment temperature.
For the spark plug working environment temperature requirements are very high, the spark plug heat is neither too big nor too small, to ensure that the working temperature of the spark plug, it must match the original calorific value. Under normal circumstances, the difference between the drop in a control, if the drop is too large, ranging from the impact of engine power output, while the spark plug damage, and thus damage the engine.
Many people know that the spark when the spark plugs can not be less than the original heat value, but that is higher than the original heat value is not, in fact, this is wrong. Dress up the spark plug, do not too much to pursue high prices of high calorific value of the spark plug, should refer to the original calorific value of the key factors to match, or easy to cause great impact on the engine performance.
