Three major symptoms of spark plug replacement--jitter, run-out, refueling delay!It has to be admitted that the probability of traffic accidents is much higher than before, and most of them are caused by vehicle owners 'mistakes. Of course, some of them may be due to the failure of the car itself, such as brake failure, or the engine suddenly failed to speed up and so on.

However, in any case, owners should also pay attention to the maintenance of the car at ordinary times. A well-maintained car not only has lower safety hazards, but also has a longer service life.

Especially some of the more important parts of the car, such as the three major parts, engine, gearbox and chassis, should always pay attention to their use. Of course, many faults in the car can actually be reflected through the fault lamp, but some faults are not necessarily reflected in the fault lamp, such as the spark plug, which is undoubtedly a very important part of the engine. If there is a problem, the impact on the car is very large, and the spark plug also has a related life. Therefore, in this issue, we will find out what happens to the car and need to replace the spark plug.

First of all, if the car is driving normally, the engine suddenly has a strong sense of vibration. We know that as long as the engine shake is relatively slight, there is basically no problem, especially when the car is just ignited and started, the engine shake will be more obvious.

However, if the car is driving normally and there is a relatively violent jitter, this situation is often a problem with the spark plug, which is likely to have aged or damaged.

Of course, if it is a three-cylinder engine model, the jitter will be more obvious, and exclude the three-cylinder engine model, if it is a four-cylinder engine model, the car encounters this situation and needs to replace the spark plug in time.

Second, if the car is driving, there will often be a "car" situation. I believe everyone has experienced it before, usually when the speed is 30-60 kilometers per hour.

There was a noticeable lack of power when it came to upshifting the car. Also, if the car is driving at a constant speed, it feels that the engine cannot provide sufficient power, but the fuel consumption is rising sharply, and the exhaust pipe may even emit black smoke. This time basically means that the spark plug has died and needs to be replaced in time. Some owners feel that there is no need to drag, this is not allowed, it is easy to cause greater damage to the engine, so it is not worth the loss.

Old owners with a little experience should know that if the power of the car drops but the fuel consumption rises, it is often caused by serious carbon deposition, and carbon deposition will occur in many parts of the engine.

Especially the spark plug, if a large amount of carbon is adsorbed, the ignition performance will decline, the fuel mixture entering from the fuel tank cannot be fully burned, and the corresponding fuel consumption cannot provide enough power, so the start will be more meat, even if the foot steps on the accelerator, the acceleration will not be obvious. This situation can actually clean up carbon deposition, if the problem is solved after cleaning, the spark plug can be temporarily replaced.

In the third case, if the engine carbon deposit is not much, but there is still a situation where the oil is not given, it generally indicates that the spark plug performance has been seriously degraded and cannot be used in time. For example, when everyone is driving, the power is relatively slow when they step on the accelerator, and it will take a while to respond, and it is accompanied by engine shake.

This situation shows that the spark plug with a long time, to the replacement stage, if not replaced in time, on the one hand will be more fuel consumption, fuel consumption will rise more obvious, on the other hand, the engine will also cause irreparable damage.

Of course, the replacement of spark plugs does not have to be too frequent. In general, most of the car spark plug replacement cycle is 2- 30,000 kilometers, if it is platinum spark plug, the life will be longer, can be replaced to about 80,000 kilometers, like some iridium spark plug, even 100,000 kilometers replacement is no problem.

General spark plugs are not expensive, and ordinary nickel alloy spark plugs are only a dozen pieces, so there is no need to prolong the replacement cycle of spark plugs because of saving money. At that time, it will cause unnecessary trouble.
