How often should car spark plugs be replaced, and how to identify whether it is good or bad?

The car spark plug needs to be changed once a month to identify its quality and quality, that is, through the smoothness of its use.

This thing can't be said, you say it has something to do with time, it certainly doesn't have much to do with it, you go to change the waste of running a thousand kilometers a year, it has something to do with the number of kilometers, people don't change it for two or three hundred thousand kilometers, I feel that the old running long distance is durable spark plugs, I'm afraid that the low speed in the idle city is so burning, and there is a point that the car that burns the oil is worn out quickly, I have seen the new spark plug because the engine is not good in winter, often flooded the cylinder, and the next day it will be replaced, so in my feeling the life of the spark plug depends on the engine and oil, The spark plug that burns well in the engine is durable, and the spark plug chokes to death because the engine burns badly! And not in the number of kilometers and in the time!

First of all, according to the mileage replacement required by the manual, the replacement mileage of the naturally aspirated engine is long, and the mileage of the turbocharged engine is much shorter.

The selection of spark plugs should be matched according to the engine model, and the service life of spark plugs of different materials is also different.

Be sure to use big brands**, ** are not much different. Fakes are sold by **.

The spark plug is a wearing part, and whether it should be replaced or not will affect the ignition in the cylinder, and excessive carbon deposition will affect the engine performance.

It is recommended to replace it once every 25,000 km (depending on the quality of the spark plug).

Car spark plugs should generally be replaced once a year. I don't know how good or bad it is.

I don't know a lot about cars, but I've heard about them, and I think it's good to change them every six months.

The spark plug made of nickel is generally changed after driving 30,000 kilometers, and it is not necessary to insist on using it.

Well, I think it should be replaced every year. When it doesn't catch fire, it feels like it's broken.

I think basically you have to fix it every few months, and if it takes too long, something will happen.

The spark plug of the car should be changed often, and if it is not changed for a long time, it may not catch fire.

I don't know much about trains and so on, because I think I should change them often, because after all, I have to ensure the safety of trains.

Spark plugs are the same as clothes, old ones are not necessarily bad, general fuel consumption has increased, or it is a little difficult to start, or the tachometer is high and low when standby. It should have been changed then.

I have a very shallow knowledge of cars, especially the parts of cars, so I don't know how often spark plugs are replaced.

Ordinary 2 to 30,000 kilometers can be replaced, mainly to confirm the degree of combustion of the central electrode.

Suzuki antelope 130,000 kilometers, still the original car! Okay very!

Isn't it better to change it once a day?

I drove more than 110,000 kilometers and still used the original car.

Octavia RS, 70,000 kilometers is still the original car spark plug, and the idle speed is as stable as Mount Tai.

It's like changing clothes, you have to change it every day.

I wash the car and fill the tires in the 4S shop, so I believe them.

Check the quality of the spark plug: check whether the spark plug is jumping or short-circuiting in the real car; Observe the color of the spark plug; 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 specific inspection of the quality of the spark plug is as follows:

1) Flashover: unscrew the spark plug, put it on the cylinder block, and test the fire with a high-voltage wire, if there is no spark or the spark is weak, it indicates that the spark plug is leaking or not working.

2) Short circuit: Let the engine idle and use a screwdriver to short circuit the spark plug cylinder by cylinder, listen carefully to the changes in engine speed and sound, the speed and sound changes are obvious, indicating that the spark plug is normal. When the speed and sound are not obvious, the spark plug is in an abnormal state.

2. Observe the appearance color: remove the spark plug to observe, and judge the use of the spark plug according to the following appearance color observation:

1) If the spark plug is severely ablated, and the top is scarred, black, cracked, and the electrode is melted, it indicates that the spark plug has been damaged and must be replaced immediately;

2) If it is smoked black, it means that the spark plug is selected incorrectly or the mixture is thick, and the oil is on the way;

3) If there is a deposit between the top and the electrode, and the deposit is oily, it proves that the cylinder channel oil has nothing to do with the spark plug; If the sediment is black, it means that the spark plug has deposited carbon and bypassed; The gray color of the sediment is due to the lack of fire caused by the additives in the gasoline covering the electrodes;

4) If it is russet or rusty, it means that the spark plug is normal;

5) If it is oil-stained, it indicates that the spark plug gap is out of balance or too much oil, and the high-voltage line is short-circuited or broken.

Whether it can start normally: see whether the cold car is smooth when starting, whether there is a particularly obvious "frustration", and whether it can be ignited normally.

Look at the engine shake: keep the car idling, if the engine can run smoothly, it means that the spark plug can work normally; If you notice that the engine is shaking intermittently or continuously, and makes an abnormal "bump" sound, it means that there may be a problem with one of the spark plugs, and the spark plugs need to be replaced.

Check the electrode gap of the spark plug: when you remove the spark plug, you will find that the spark plug has a discharge electrode, the electrode has a normal consumption, if the gap is too large, it will lead to a failure to discharge normally (the normal spark plug gap is, in this case it will cause your engine to be weak. At this point, it must also be replaced.

Check the appearance of the spark plug: remove the spark plug, first check whether the spark plug has cracks, rust, wear, looseness, if the above phenomena exist, it means that the spark plug needs to be replaced.

The structure of the car is relatively complex, and there are many parts, and the spark plug is one of the parts. It is also very important for the car, once the spark plug is abnormal, then the car cannot run and cannot go out. So if you want to judge whether your spark plug should be replaced, you can use whether the engine shakes during driving.

And when driving, whether there is an ignition stall for unknown reasons. Spark plugs do not need to be replaced as often, only at regular intervals. <>

And when changing the spark plug, the selection cycle is also different according to the different materials. Under normal circumstances, the spark plug of the car should be replaced in time when it travels about 40,000 kilometers. However, if you buy a car with a relatively high price and drive about 80,000 kilometers, you need to replace it.

If in the process of driving, the phenomenon of engine shaking is found to be more serious, then in this case, it is necessary to consider whether there is a problem with the spark plug and should be replaced in time. <>

Because under normal circumstances, the car should be very stable during driving, and give the driver a very good experience. However, as long as the spark plug is abnormal and cannot be ignited, a violent noise will occur. If not replaced in time, it is likely to leave the engine, causing excessive damage.

And if the car is regularly maintained, after all the minor abnormalities and minor faults are repaired, when it is on the road, it will drive normally, and there will be no stalling for no reason. <>

If there is an unknown flameout, it may be that the spark plug is aging and abnormal, and it should be replaced in time. It can also be judged in time by the shape of the spark plug. If on top of the spark plug, a large amount of carbon deposits.

After cleaning, it can be ignited normally, and there is no need to replace it. However, if it cannot operate normally after cleaning, it means that the spark plug is already in a damaged state at this time, and a new spark plug needs to be replaced in time.

It should be replaced in time every three months, when the spark plug should be replaced, the speed and sound are not obvious at 1 point, the burning of the spark plug is particularly serious, and then there is a black line or rupture on the top, and the cylinder has a situation of channeling oil.

It can be judged by fuel consumption, by the situation of shaking, by the ignition system, and by the way the vehicle is started. It doesn't need to be replaced as often.

In general, if the specified service life is exceeded, and there is an obvious system failure, the response is not particularly sensitive; I don't think it needs to be replaced often, and if you have any of the above symptoms, you need to replace it.

Many drivers believe that when there is a problem with the start of their car, they think it is the battery that is wrong. But it's not necessarily that there's a problem with the car battery. Old or defective spark plugs could be the culprit!

After all, these spark plugs still have important work to do. I wonder how often the spark plug in my car is changed? Here are six signs of blight.

1.The engine fault light is on.

A worn spark plug or spark plug wire can trigger the engine fault light to illuminate. If something goes wrong while the car is moving, the most obvious thing should be to check if the engine lights are on, or even flashing.

This may cause the engine to catch fire, and the check engine light will illuminate. As a rule of thumb, an engine failure light may indicate a potential fault in the engine that is on fire.

In general, it is best to replace the spark plug according to the manufacturer's specifications as part of preventive maintenance. This can help you avoid costly maintenance, as driving without a spark plug can put undue strain on your car's catalytic converter (the engine's exhaust purifier). Symptoms of spark plug non-ignition include rough machining, uneven power when accelerating, and increased exhaust emissions.

As a final check, engine failure lights can be caused by a variety of factors, not just spark plugs.

2.Car driving problems.

Engine spark plugs are one of the most important working parts in a vehicle that power the engine! Old, worn spark plugs are harder to produce the sparks that actually power the engine. If you stop while trying to open your car, the spark plug or spark plug wire may be damaged.

If your car won't start at all, the battery is likely to be the culprit.

3.Increased fuel consumption.

If your spark plugs are about to be replaced, they will use your gas mileage to calculate. Worn spark plugs can increase your vehicle's fuel consumption because they don't burn the fuel that goes into the engine efficiently, which means you'll pay more money when it's full.

4.There is noise in the engine.

Normally, the engine runs quietly. If you notice that the engine is making abnormal noises, pops, or knocks, then your spark plug may be faulty.

5.The car cannot accelerate.

You are probably very familiar with how your vehicle runs and drives. If you find that your car is not responding as quickly as it normally, especially when accelerating, it can be considered that there is a problem with the spark plug. It's time to replace them. No one likes to drive a car that doesn't accelerate and consumes gas.

6.Replace the spark plugs regularly according to the manufacturer's instructions.

In any car care, it is best to follow the manufacturer's recommended maintenance time. Check your vehicle's recommended maintenance intervals to find out how often your vehicle's spark plugs should be replaced.

Fortunately, spark plugs don't wear out quickly. You can usually travel 80,000 miles before you need to replace the spark plugs.

However, if the above symptoms are found, it is necessary to check for spark plug failure through an engine inspection to determine that the car's spark plug needs to be replaced.

The following is how to determine whether the spark plug needs to be replaced: 1. See if the engine can start normally. 2. Look at the engine shake and check the electrode clearance of the spark plug.

3. If the color is russet or rusty, it means that the spark plug is normal, if it is oily, it means that the spark plug gap is out of balance or too much oil, and the high-voltage wire is faulty. 4. If the spark plug is severely ablated, the top of the spark plug is scarred, black lines, cracked, electrode melting, etc., indicating that the spark plug has been damaged and must be replaced immediately. Additional Information:

The spark plug, commonly known as the fire nozzle, is used to send the pulse high-voltage electric discharge sent by the sorghum simple pressure wire, and the air between the two electrodes of the spark plug is sparkedThe mixed gas in the gas cylinder ensures the normal operation of the engine, and the spark plug is an important component of the ignition system of the gasoline engine, which is mainly composed of wiring nut, insulator, wiring screw, slag elimination rod, central electrode, side electrode and shell, and the side electrode is welded on the shell.

There are several ways to determine that the spark plug needs to be replaced:1Check the wiring condition to make sure the wiring is scattered.

2.Check whether the spark plug seal is in good condition, and replace it in time if it is damaged. 3.

Disassemble the spark plug and inspect the spark plug body for burnt marks, cracks or other anomalies.

There are two reasons for the group to carry it down:

1. The gap between the spark plug electrodes is too large.

The working environment of the spark plug is high temperature and high pressure, after using it for a period of time, part of the electrode will be oxidized and then ablated, resulting in too large electrode gap, so that the ignition energy decreases, and can not be ignited normally, which will affect the normal operation of the engine, and the spark plug in this case must be replaced.

2. Too much carbon deposits on the spark plug electrode.

Due to the poor condition of the vehicle, the insufficient combustion of gasoline produces carbon deposits, which accumulate on the spark plugs, because the carbon deposits can conduct electricity, and eventually the carbon deposits are too much and the electrodes are short-circuited, so that the electrodes fail to ignite.
