For family cars, what are the situations that require the replacement of spark plugs?

The spark plug, which is a key component in the engine ignition system, introduces the high-voltage electricity generated by the ignition coil into the engine cylinder, and generates the mixed oil and gas in the spark plug electrode to ignite the gas cylinder, thereby promoting the engine to produce work.

Automobile spark plug maintenance masters like to use the "fire nozzle" to honorifically name, its role is mainly through the generation of electric sparks, so as to ignite the gas mixture in the cylinder, to promote the engine work. The specific life of the spark plug is not specified, because the material is different, under normal circumstances, the spark plug needs to be replaced once after 30,000 kilometers, in order to burn better. However, if some external reasons will also lead to premature aging of the spark plug, in fact, as long as we pay attention to the use of the car, we can find that the spark plug has begun to have problems.

When you get into the car, there are unstable idling, shaking, and insufficient acceleration power, all of which are caused by damage to the spark plug, and you should drive to the repair shop to check. One of these failures is that the spark plug has deposits sticking to it, and due to the long-term use of the spark plugs, the deposits will become thicker and thicker, and eventually the spark plugs will not work properly. Second, due to spark plug ablation, if the temperature in the combustion chamber is too high, resulting in too much carbon in the combustion chamber, resulting in too small valve clearance, it is easy to cause the spark plug electrode melting and ablation.

Because the working condition of the spark plug is related to the use of the vehicle, it must be dealt with in time.

Sometimes when we go to the 4S store, the service consultant will suggest whether to upgrade the spark plugs, which is actually redundant. Generally speaking, the original spark plugs have been rigorously tested by the factory to meet the needs of daily driving, and the best balance between economy and power has been struck. But if you're looking for power, you can replace the better, more expensive spark plugs and upgrade them appropriately.

To sum up, in a word: develop good driving habits. This sentence seems simple, but it is estimated that not many people actually do it. If you can't have a good driving habit, you should at least do it according to the recommendations of the operator's manual.

First, the engine shakes badly.

Whether the engine can be started smoothly occupies an important role, and the spark plug is the key part, whether the car can run stably and continuously, it depends on whether the engine is powerful, but whether the engine can work normally, without the first flower plug, once there is abnormal shaking, pay attention quickly, otherwise the engine will be overhauled.

Second, abnormal starting.

If it doesn't catch fire for a long time, it means that the spark plug needs to be replaced, don't wait until the car turns off and can't move, it's too late.

Third, there is a situation of shrugging.

Under normal circumstances, the car is relatively stable, and there will not be much abnormal movement, but when the car is sensational, it may be insufficient fuel supply, and the driving is fast and slow, which is the result of the instability of the spark plug.

Many car owners don't know the role of spark plugs and don't know the replacement cycle of spark plugs. When they were doing maintenance, they heard the 4S shop say they wanted to replace the spark plugs and they felt like they were cheating on themselves. The role of the spark plug is to introduce high-voltage electricity into the cylinder, which then creates a spark to ignite the fuel.

Because sparks are generated even when high-voltage currents are applied frequently, spark plugs have a loss process that needs to be replaced regularly.

What's wrong with the vehicle that means the spark plug needs to be replaced? Spark plugs are made of different materials. Ordinary spark plugs are made of nickel alloy and can be replaced every 30,000 km.

There is also a spark plug whose electrode part is made of platinum. This spark plug is made of good material, so the replacement cycle is about 60,000 kilometers. These two types of spark plugs are now widely used.

Generally, it can be replaced according to the cycle.

Of course, the replacement cycle of the spark plug is not absolute, and the use habits of the car owner will also affect the loss and carbon deposition of the spark plug. Because the spark plug is an ignition part, it is possible that the spark plug is not working properly when ignition is difficult, the ignition is not normal, or it is shaking, so it is necessary to check whether it needs to be replaced. As for the spark plug, although it is a small accessory, it is recommended that the owner do not replace it himself.

Different spark plugs generate different heat and must be replaced to match their own vehicles. Otherwise, not only will they not work very well, but they will also affect the starting and normal operation of the vehicle. Another thing to remind car owners is that each cylinder is equipped with a spark plug, so there will be multiple spark plugs on a car.

The exact quantity depends on the number of cylinders.

When replacing spark plugs, replace all of them, not just some. Very noticeable engine shake is frequent. Of course, occasional engine shake may not be a problem, but if this problem occurs frequently during normal driving, it is likely to be caused by aging or even damage to the spark plug.

The premise, of course, is to eliminate the effects of a three-cylinder engine, which is quite common. If it is not a three-cylinder engine model, if the engine shakes significantly, the owner should pay attention to replacing the spark plug.

1. Acceleration is not smooth: in the process of driving, if it is found that the car is unable to accelerate or there is a meal during acceleration, resulting in no linear acceleration of the vehicle, it is likely to be caused by the decline in the performance of the spark plug, due to the electrode gap of the spark plug is too large, the ability to ignite is unstable or can not be ignited at all, resulting in the vehicle being unable to meet this situation when accelerating, the spark plug can be checked. 2. The fuel consumption of the car increases

The spark plug of the car can also be checked through the fuel consumption of the car, the car is more and more fuel-intensive, not as smooth as before, and there is no force when accelerating, and it is recommended to consider replacing the spark plug when a similar situation occurs. 3. It is difficult to start the car: it is difficult to start the car, which may be due to the failure of the spark plug.

Because if the gap between the spark plug electrodes becomes larger, its ignition energy will become weaker, resulting in the mixture not being ignited in time, and the phenomenon of difficulty in starting occurs, which leads to the phenomenon of difficult starting of the car is not only the spark plug, but also the owner should consider comprehensively. 4. Engine idle shaking: when the engine is running at idle speed, it feels the steering wheel shaking, when the engine speed increases, the shaking phenomenon disappears, and the shaking phenomenon no longer occurs when stepping on the accelerator to accelerate, and similar situations indicate that the performance of the spark plug begins to decline and needs to be replaced in time.

1. Generally, it is a very stable state in a normal state, and if there is a shaking, it proves that the spark plug needs to be replaced. 2. It is the phenomenon of shrugging when upshifting, the engine is obviously insufficient power, fuel consumption is large and accompanied by black smoke, which means that there is a problem with the spark plug and needs to be replaced. 3. It is that the car suddenly turns off irregularly at slow speed, and it is difficult to re-ignite after the ignition is turned off, and sometimes it is even impossible to start the car, which is also a problem with the spark plug that prompts you to replace it.

The spark plug is aging and the carbon deposition is serious; Organic oil precipitation phenomenon of spark plug insulator skirt, electrode, central electrode and shell; Lead precipitation occurs in the spark plug insulator skirt, and there is also a situation where the spark plug needs to be replaced, which is to increase the power.

I can't start the car, I don't feel like I accelerate when I step on the accelerator, I have a frustration when driving, the engine shakes badly, and the spark plug has been ablated.

Generally, there is no fire in the morning, and it takes two or three times to start, and there is a sense of frustration when driving, the acceleration is particularly slow, or there is no strength, and the consumption of oil has increased significantly, and the above situation shows that the spark plug should be replaced.

poor acceleration; The engine appears to be "shrugged"; Regular engine shake; Automatic flame-out irregularity; The vehicle mileage is more than 30,000 kilometers, or more than 8 years.

Generally, when the first time the ignition is not good, it has to be played two or three times, when driving, I feel particularly weak, as if I can't add oil, it is very fuel-efficient, and the engine shakes very much, indicating that the spark plug should be replaced.

Due to spark plug ablation, if the temperature in the combustion chamber is too high, resulting in too much carbon in the combustion chamber, resulting in too small valve clearance, it is easy to cause electrode melting and ablation of the spark plug. Due to the long-term use of the spark plug, the deposits on the spark plug will become thicker and thicker, which will eventually cause the spark plug to not work properly; Diagnosis of insulator tip fragmentation: Generally speaking, detonation combustion is the main cause of insulator breakage.

Ignition too early, low octane number of gasoline, and high temperature in the combustion chamber can all lead to engine knock combustion.

If you slowly find that your car is more and more fuel-guzzling, and the power loss is relatively large, and it does not have the smoother feeling of driving before, similar to this kind of car, we can also consider whether the spark plug should be replaced. The engine lacks fire, what is the lack of fire, that is, there were originally four cylinders ignition, but now it has become three, and the four-cylinder engine becomes a three-cylinder engine. If the spark plug is severely ablated, with scarring, black lines, cracking, and electrode melting at the tip, this indicates that the spark plug has been damaged and must be replaced immediately.

The engine is mainly ignited by spark plugs, and when the mixture is ignited, the spark plugs are not ignited only once, but continuously. At this time, the performance of the spark plug is weakened, and the idle speed of the vehicle is unstable after starting, and the power is weakened. There is a fast and slow performance of the vehicle during the journey, and the general situation is also the cause of the spark plug.

Diagnosis of rounded electrodes and scarring of insulators: This indicates that the engine has been ignited too early, which may be caused by too early ignition or too low octane number of gasoline and too high calorific value of spark plugs.

Spark plugs are wearing parts, in our daily driving process, its service life and the driver's driving habits are also very directly related, and we should also have a little bit of relevant knowledge when buying spark plugs, to avoid being deceived by unscrupulous traders. If it is determined that the spark plugs need to be replaced, then be careful not to replace the single one, but to replace it in sets.

If the car has increased fuel consumption or lack of power, it may be necessary to replace the spark plug.

Generally, the spark plug needs to be replaced after 4 to 60,000 kilometers. Spark plugs and ignition coils are important components in the engine ignition system, and spark plugs are a wearing part that needs to be replaced regularly. If the spark plug is used for a long time, it will cause the electrode gap to become larger, which will affect the ignition of the spark plug.

The spark plug is an important element of the ignition system of a gasoline engine, which can introduce high-voltage electricity into the combustion chamber and cause it to skip the electrode gap to generate a spark, thereby igniting the combustible mixture in the gas cylinder. The spark plug is mainly composed of a wiring nut, an insulator, a wiring screw, a central electrode, a side electrode, and a shell, and the side electrodes are welded to the housing.

It is difficult for the car to start cold, there is obvious frustration, idle shaking, frequent idle self-stalling phenomenon, engine acceleration performance decreases, power is insufficient, and fuel consumption increases. At this time, it is necessary to check and replace the spark plug in time.

First, I don't love to play fire in the morning, and it takes two or three times to start.

Second, there is a sense of frustration when driving. Weak or slow acceleration.

Third, the engine shakes badly when idling. (Most of them are caused by the damage of the spark plug of a certain cylinder).

When the car first starts, the engine shakes significantly. If the car is running properly and there is severe vibration, this is usually a problem with the spark plugs, which may age or become damaged. In the case of a three-cylinder engine model, the jitter will be more noticeable.

At speeds of 30-60 km/h, there is a noticeable lack of power when you want to upshift. If the car is driving at a constant speed, it will feel like the engine is not providing enough power, but fuel consumption is rising dramatically, and the exhaust pipe may even emit black smoke. This basically means that the spark plug is broken and needs to be replaced in a timely manner.

Experienced car owners should know that if the power of the car decreases, this is often caused by severe carbon deposits, and carbon deposits can occur in many parts of the engine. If a large amount of carbon is adsorbed on the spark plug, the ignition performance will be reduced. The fuel mixture entering from the fuel tank does not burn completely, and the corresponding fuel consumption does not provide sufficient power.

If the problem is resolved after cleaning, the spark plug cannot be replaced for the time being. If the carbon content is not high, but the fuel is not sucked in, the performance of the spark plug will be severely reduced and it will not be able to be used anymore. When driving, the power slows down when you step on the accelerator.

It takes a while for it to respond, and it is accompanied by engine shake. This circumstance indicates that the spark plug takes a long time. During the replacement phase, if not replaced in time, more fuel will be consumed, and the fuel consumption will increase significantly, which will cause irreparable damage to the engine.

Spark plugs do not need to be replaced frequently. The spark plug replacement cycle for most cars is 20,000-30,000 km. In the case of platinum spark plugs, the service life is comparatively longer.

They can be replaced at about 80,000 km. For example, some iridium spark plugs, even once every 100,000 kilometers, ordinary spark plugs are not expensive, ordinary nickel alloy spark plugs only cost more than a dozen yuan, saving money and not extending the spark plug replacement cycle, which will cause unnecessary trouble.
