How spark plugs work

I believe everyone has a certain understanding of the spark plug, which is an important part of the engine ignition system. As for the working principle of the spark plug, it is actually that the spark plug’s electric board ignites through repeated and continuous power generation, and the generated pulse high voltage electricity breaks down the air between the two electrodes of the spark plug, forming a spark and generating an explosion to induce the mixed gas in the gas cylinder, and then the engine Will start to operate.

The spark plugs are consumables, so they naturally need to be replaced regularly. So what kind of spark plug to choose will directly affect the operation of the engine. But when we replace the spark plug, many people only pay attention to its material and number of poles. In fact, the calorific value of the spark plug is also very important. If you choose spark plugs with different calorific values, it is easy to affect the output of the engine, and it is even possible that the spark plugs are directly scrapped. So let's by the way talk about how to see the calorific value of the spark plug.

Where to see the heat value of the spark plug:

The calorific value of the spark plug is represented by numbers, and these numbers are usually located in the middle of the model. For example, if the model is BP5E S -1 1, then the number 5 is the calorific value of the spark plug. It is worth mentioning that the calorific value of different brands is different, and the calorific value of each brand has its corresponding model, so we must pay attention to it when purchasing.
