When is the spark plug replaced? Once this happens, change it immediately!

With the development of the national economy, the car as a convenient travel tool has entered thousands of families, but some parts of the car need to be replaced occasionally, otherwise it will cause great damage to the car. Today, let's talk about one of the spark plugs. If this happens, the spark plug must be replaced or the engine will be replaced!

First, let's get to know the spark plug. We can think of the spark plug as the heart of the engine.

A spark plug is a device that ignites a mixture of gasoline and air that enters the engine for combustion. It is also one of the most vulnerable parts in the gasoline engine, because it works under high temperature and high pressure for a long time. It plays an important role in the engine operation, which is closely related to the fuel economy and stable operation of the car.

The common faults of spark plug can be divided into two types: one is the serious ablation of spark plug, the other is the deposition on the spark plug. When the owner finds that there is scar or damage on the top of the spark plug and the electrode is melted or ablated, it means that the spark plug has been damaged. At this time, the spark plug should be replaced. During the replacement process, the owner can first check the symptoms of spark plug ablation and color change.

The spark plug gap is large and unlikely to be damaged, so it is not necessary to replace it. As long as the spark plug gap is not full of carbon deposits, the electrode of the spark plug can be adjusted to the parameter value, and then connected to the high-voltage wire to check whether the spark plug is running normally. If the spark plug does not jump or the jump is weak, it will be damaged. If the runout is normal, there is no need to replace the spark plug. If there is only a slight amount of carbon deposition, first remove it with a hacksaw blade or suitable tool, then adjust the spark plug clearance, then connect to the high voltage line to check the jump fire. If it is normal, it can continue to be used. If the fire is weak or does not jump, it must be replaced.
