Cars are travel tools that everyone generally uses, and now there are more people buying cars. For the safety of themselves and others, the maintenance of the car is crucial. Many of the car's small accessories are not negligible. Take the spark plug, it can be said to have a decisive role in starting the engine. The spark plug is a very critical component in the ignition device. Its quality has a direct impact on the operation of the engine. For those who want to change the spark plug, they must have a common question, that is, what brand of spark plug is good ? Let me introduce it to you today.
What is the role of spark plugs ? Everyone should be familiar with it. If you don't know, you can also search on the Internet. The introductions are quite detailed. Here, the Xiaobian is not too much, just a simple mention, it is convenient to introduce the following. What brand of spark plug is good.
The function of the spark plug is to introduce high voltage electricity generated by the ignition coil into the engine cylinder, and a spark is generated between the gaps of the spark plug electrodes to ignite the mixture. Gasoline engines are powered by timely combustion of fuel and mixed gases, but gasoline as a fuel is difficult to ignite spontaneously even in high temperature environments. It is necessary to use a "fire" to ignite it in order to burn it properly. The spark ignition mentioned here is the role of "spark plug".
It is conceivable that the working environment of the spark plug is very bad. It must be in a high-temperature gas combustion chamber of up to 2000 ° C above the temperature. Naturally, if the absorbed heat cannot pass through proper discharge, it will inevitably cause high temperature oxidation and erosion (burning). Therefore, the design of the spark plug has to consider the characteristics of heat dissipation. Here is a terminology related to spark plugs, called calorific value. What does the calorie mean? I know everything.
To say so much in the above is actually to bring out this calorific value. In general, the standard for selecting a spark plug is a suitable principle, a low calendering ratio is used for a high calorific value type, and a high compression ratio is used for a low calorific value. The higher the heating value of the spark plug, the higher the working temperature required. If the car is not ideal, it will not use a good spark plug.
Spark plug brand
There are quite a few well-known spark plug brands. Bosch , NGK , and HKS are all good, and there are many modifications, but you should also pay attention to the car. If it is a relatively ordinary engine, it is enough to use the original spark plugs, such as champions , torches , Bosch, etc.; a better car, you can use gold-plated spark plugs, among which the brand of spark plugs has electric equipment , LDH , and thunder. Hey, etc.
There are many brands of spark plugs, and there are many famous ones in China. Xiang Torch , Liben , and Starlight are quite good. And the big brands are just a few, as long as the model is right, the quality can be passed. In addition, it depends on what the electrode material of the spark plug is. Platinum is more durable and the sheet metal is stronger.
Choosing a spark plug, the main thing is not the brand, (of course, it is not that the brand is not important, and can not use those brands that are too rubbish) mainly depends on the model, specifications, performance parameters, etc., some small brands of spark plugs are very good, Such as customized.
Spark plugs are easy-to-damage parts. Generally, ordinary spark plugs need to be replaced at 30,000 km. The life of rare metals will be longer, but they will be replaced regularly. 60,000 km of platinum and 80,000 km of sheet metal. The proposal is about to be replaced. Well, what brand of spark plug is good , I will introduce so much for everyone, I hope to help everyone.
