The precursor to the spark plug that needs to be replaced

With the popularity of cars, many friends have cars. Cars are closely related to our lives and we rely on them for daily travel. However, once the car breaks down, it will also bring a lot of trouble. The car has a very small but very critical part, which plays a vital role in the operation of the car. It is the prerequisite for whether the car can operate, and it is the spark plug.

The spark plug is the heart of the engine. Once a problem occurs, it will affect the operation of the car. What happens to the spark plug to be replaced? In other words, what is the precursor to the need to replace the spark plug?

The spark plug is a device used to ignite the fuel of the engine. Only when the fuel is ignited, the engine can operate and the car can be started. The spark plugs currently on the market mainly include nickel alloys, silver alloys, yttrium gold, platinum, iridium gold, iridium platinum and other types, and the replacement cycle will vary depending on the material.

Generally speaking, the service life of ordinary spark plugs is about 20,000 to 30,000 kilometers, while the service life of precious metal materials can reach about 60,000 to 100,000 kilometers. Of course, these replacement cycles are only theories under normal conditions. The specific replacement cycle depends on the vehicle. The actual use of the spark plug, the owner can judge the use of the spark plug by changing the state of the vehicle. How to judge whether the spark plug needs to be replaced, the signs of replacement are as follows:

1,The car is difficult to start or fails to start

When starting the car,discoverIt is difficult to start, or even failed to start, which means that the car may have problems with more than one spark plug, or there may be problems with multiple spark plugs, and the spark plugs need to be checked and replaced.

2,Poor car acceleration

Because the electrode gap of the spark plug is too large to provide stable ignition energy, the acceleration of our car is not smooth, there is shaking, and the spark plug needs to be replaced.

3.Carbon deposits on spark plugs

If the engine burns oil or burns incompletely, it will cause black grease on the spark plug. This is carbon deposits, which will cause the spark plug to fail to ignite normally. At this time, the spark plug needs to be replaced.

4.Abnormal ignition of spark plug

Remove the spark plug, plug in the sub-cylinder line, or use the motor to start the engine, and it is found that the spark plug pole flashover is normal as a blue flame. If the spark is weak, red or the spark is not in the middle of the pole and jumps around, you also need to replace the spark plug.
