How often should the original car spark plug be replaced?

The original spark plug is made of ordinary nickel alloy, which is 3-40,000 kilometers and replaced, and some will be 20,000 kilometers. The original spark plug of some cars will be equipped with a better platinum spark plug, which can reach 5-80,000 kilometers.

The spark plug of the original manufacturer of the car owner should go to the repair shop to replace the spark plug in time when the replacement cycle is reached, and the ignition gap of the spark plug will become larger after 20,000 kilometers, and the ignition performance will also decrease. However, the owner can replace the spark plug without the spark plug of the original material, or the spark plug with a better material and longer life.

There are differences between different materials of spark plugs, ordinary spark plugs are made of nickel alloy, and this kind of spark plug is about 30,000 kilometers to replace it.

There is also a spark plug made of platinum for the electrode part, which is made of good material, so the replacement cycle is about 60,000 kilometers. These two types of spark plugs are used more now, and in general, they can be replaced according to the cycle.

Due to the different materials of spark plugs, the types of spark plugs can be divided into: ordinary copper core, yttrium gold, platinum, iridium, platinum-iridium alloy spark plugs, etc., the service life of these types of spark plugs is different, and the corresponding replacement mileage is also different, so it is necessary to distinguish clearly when choosing.

Generally speaking, under normal use, the service life of ordinary spark plugs is 30,000 kilometers, while the service life of spark plugs of advanced materials is 6 to 90,000 kilometers. Do not extend it so that it needs to be replaced at the right time.

If you find that the fuel consumption of the vehicle increases, you can consider whether to replace the spark plug, and the general repair shop will recommend replacing it after 20,000 or 30,000 kilometers, because at this time, although the spark plug is not completely damaged, the efficiency has decreased. In fact, this is determined by the quality of the spark plug, the ordinary spark plug can be changed once every 3-40,000 kilometers, and the platinum and iridium can be changed once for 6 80,000 kilometers. Generally in the tens of yuan to a hundred yuan.

Then find a reliable repair shop for installation, the installation process is very short, you can generally check it yourself, which can not only save money but also avoid the black heart repair shop to reuse the half-used spark plugs removed from other people's cars.

How often the original spark plug is replaced is mainly determined by the material of the original spark plug.

If the original spark plug uses a resistive spark plug, the replacement cycle is to change it once every 20,000 kilometers.

If the original spark plug uses a platinum spark plug, the replacement cycle is 40,000 kilometers to replace it.

If the original spark plug uses an iridium spark plug, the replacement interval is 60,000 to 80,000 kilometers.

The replacement cycle of the spark plug will also be affected by the model and manufacturer, because the maintenance cycle specified by different manufacturers and different models will be different, so the specific replacement cycle of the original spark plug should be carried out according to the manufacturer's standard.

According to my many years of experience, there is a judgment standard, mainly to judge whether the idle speed pointer after the car starts whether there is a floating situation, whether the car starts the process of wearing forward or instigating the phenomenon, whether there is shaking at the moment of acceleration or overtaking, whether the acceleration is weak, and secondly, whether the fuel consumption has increased in the near future, the traditional spark plug is a single iridium, which is easy to make gasoline burn, to a large extent, it has a good oxidation ability to reduce fuel consumption by 11%, so the service life will be relatively long, and the platinum core is recommended to be replaced every 80,000 kilometers. It is recommended to replace the iridium core every 100,000 kilometers, of course, in reality, you can also run an extra 10,000 kilometers to replace it, because there is a redundant design.

The manufacturer's recommended mileage is generally conservative. In fact, it can be appropriately extended, many vehicles have not been changed for 100,000 kilometers, but some cars have been changed for tens of thousands of kilometers. So there is no accurate time and mileage.

It is better to replace it according to the manufacturer's requirements to avoid the vehicle breaking down. When accelerating, the speed always feels like it can't be raised In the above situation, you can check the spark plug of your car, check it yourself, and go to a professional place if you don't understand, after all, the spark plug is the "heart of the heart of the car".

For example, Mazda, Qijun, these Japanese cars are good, the manual is 120,000 to change, if you 09 car, the number of kilometers has not arrived, there is no need to change, the general manufacturer of domestic cars says that 20,000 for change, can be 40,000, now there are good alternatives, as for how long the car spark plug is replaced, my experience is that 50,000 kilometers or two years can be replaced, but it is not absolute, if 50,000 kilometers does not appear abnormal in the engine, you can check whether the spark plug is a problem, if there is a problem, then replace it.

The maintenance master said that it can be changed a little later, I am 60,000 to change once, the old spark plug is removed to see, the master said that the light yellow is in good working condition, the black one is a bit of a problem, now it has been changed twice, and the engine is working normally.

The spark plug of the car is about once every 30,000 kilometers, and it is already very worn out at this time.

Answer Autumn is high and cool, the mountains are red all over, in this fruitful golden autumn, I wish you wealth like autumn rain, love like autumn water, troubles drifting away with the autumn wind, career as mature as autumn fruits, and a clear mood like the autumn moon.

The replacement cycle of automobile spark plugs depends on the material of the spark plugs, and the spark plugs made of ordinary nickel alloy materials are best changed once in about 20,000 kilometers, and this spark plug is mostly used in low-end models (domestic cars); The spark plug made of iridium is changed once in about 60,000 kilometers, and the spark plug of this material has strong stability and is mostly used in high-end models, and it is a widely used spark plug at present.

The replacement cycle of spark plugs generally depends on the mileage of your car, if your car has traveled enough for 60,000 kilometers, then you must replace the new spark plugs in time to avoid problems.

Actually, I don't know this very well, because of this, I don't use it for a long time, and I usually wait until it has a problem, then I will replace it.

There is no fixed time for the replacement of spark plugs, depending on the material of the spark plug.

The replacement interval for resistive spark plugs is usually 2 to 30,000 km.

The replacement cycle of platinum spark plugs is 4 to 60,000 kilometers, generally 40,000 kilometers for single platinum spark plugs and 60,000 kilometers for double platinum spark plugs.

Iridium Liquor Eggplant Gold Spark Plug Base Collapse Instinct can be used for 8 to 100,000 kilometers.

General normal maintenance recommended replacement kilometers in 40,000 to 60,000 kilometers. In addition, there are two situations that also need to be replaced: first, during the normal driving process, the starting type reeds machine lights up and is accompanied by shaking, and the fault code is read to show that there is a fire, and it is necessary to check whether the ignition coil and spark plug need to be replaced.

2. Remove the spark plug to check whether the ignition head is seriously ablated, and if it is serious, it needs to be replaced.

1.The combustible mixture is thick. The remaining part of the unburned will accumulate on the spark plug electrode and carbonize, which will lead to the spark plug jumping abnormality until it is damaged by carbon.

The reason for the excessive concentration of the combustible mixture is generally that the oil level of the carburetor is too high, the main air volume hole of the carburetor is blocked, and the core of the air filter is seriously blocked. In addition, the choke door of the carburetor is stuck and cannot be fully opened, or the thickening valve is not working well, which is also the cause of the overconcentration of the combustible mixture.

2.Engine channeling oil. In the process of engine work, if the exhaust pipe emits blue smoke and black smoke, it indicates that excess oil enters the air cylinder, and it will make the spark plug electrode produce a large amount of carbon deposit, or be wetted by the engine oil and can not jump the fire, this phenomenon is commonly known as engine oil.

For two-stroke engines, check whether the oil pump volume of the oil pump is too large, and whether the rod sleeve seal and check valve are invalid; In the case of four-stroke engines, the piston rings on the pistons, especially the oil rings, should be checked for wear. Then remove the intake valve and check the head and back for carbon deposits and wet grease. If the valve and valve guide are seriously worn, the valve guide oil seal is hardened or the oil seal lip is worn excessively, it will cause the fitting gap to be too large and lose the function of the dense ante seal.

These two abnormal conditions will eventually cause the oil in the valve rocker chamber to be sucked into the cylinder along the valve shaft when the air intake is summed, resulting in the phenomenon of burning oil. In this regard, the valve guide, oil seal or valve should be replaced separately depending on the wear and tear.

3.In the ignition system, magneto demagnetization, ignition coil and electronic ignition inside, generator output end and ignition coil loser end of wire connection loose, as well as incorrect ignition advance time, such as improper timing, can affect ignition performance, and ignition performance is poor, can directly cause spark plug electrode carbon deposit.

4.Pay attention to whether the model and calorific value of the spark plug comply with the provisions of the instruction manual. If the calorific value is one or two gears lower than the instruction manual, the temperature of the spark plug will rise very high, and its heat cannot be dissipated in time, which will cause abnormal combustion, and eventually lead to the melting of the spark plug electrode and premature damage.

When the spark plug itself is installed and used, there are some faults that are not easy to find that also affect the ignition performance. For example, the spark plug is poorly sealed, the spark plug is not firmly fixed, the spark plug insulator is broken, etc., which should be adjusted or replaced in time.

There is no fixed time for the replacement of a spark plug and it depends on the material of the spark plug.

The replacement interval for resistive spark plugs is usually 2 to 30,000 km.

The replacement cycle of platinum spark plugs is 4 to 60,000 kilometers, generally a single platinum spark plug is 40,000 kilometers, and a double platinum spark plug is 60,000 kilometers.

Iridium spark plugs can be used for 8 to 100,000 kilometers.

The specific replacement time of the spark plug will be different due to the brand and the engine non-celery core, and the following is the introduction of the replacement time of the spark plug: 1. Ordinary nickel alloy spark plug: It needs to be replaced once for about 20,000 kilometers.

2. Hole finger platinum spark plug: replace at about 40,000 kilometers. 3. Iridium spark plug is suspicious of trembling digging:

It can be used for about 6-80,000 kilometers and then replaced. ”

The replacement cycle of automobile spark plugs depends on the material of the spark plugs, and the spark plugs made of ordinary nickel alloy materials are best changed once in about 20,000 kilometers, and this spark plug is mostly used in low-end models (domestic cars); The spark plug made of iridium rock is changed once every 60,000 kilometers, and the spark plug of this material has strong stability and is mostly used in high-end models.

The replacement cycle of platinum spark plugs is longer than that of iridium, generally about 80,000 kilometers, but the performance of platinum and iridium is similar; The replacement cycle of the spark plug made of platinum is longer than that of all the materials mentioned above, up to more than 100,000 kilometers, however, the spark plug of this material is not widely used.

Hello 1Ordinary nickel alloy spark plugs need to be replaced once for about 20,000 kilometers;

Platinum spark plugs are replaced on the left and right at 40,000 kilometers;

Iridium spark plugs can be used for about 6-80,000 kilometers and then replaced;

Car spark plugs are generally replaced once every six months or so. Because spark plugs are consumables and are often used, they should be changed at a fixed time to ensure the normal operation of the vehicle.

There is no fixed time for the replacement cycle of the spark plug, depending on the material buried in the spark plug.

The replacement interval for resistive spark plugs is usually 2 to 30,000 km.

The replacement cycle of platinum spark plugs is 4 to 60,000 kilometers, generally 40,000 kilometers for single platinum spark plugs and 60,000 kilometers for double platinum spark plugs.

Iridium spark plugs can be used for 8 to 100,000 kilometers.

Spark plugs are consumables, and there is no fixed time for the replacement cycle of spark plugs, depending on the material of the spark plug.

The replacement interval for resistive spark plugs is usually 2 to 30,000 km.

The replacement cycle of platinum spark plug is 4 to 60,000 kilometers, the general single platinum spark plug is 40,000 kilometers, and the double platinum spark plug is 60,000 kilometers.

Iridium spark plugs can be used for 8 to 100,000 kilometers.

There is no fixed replacement time for spark plugs.

If there is no problem with the spark plug, it will not be too late to dig and use it, and the key Dan group will tell you that it will be changed for tens of thousands of kilometers, which is purely a manuscript orange cheating money.

When doing maintenance, it is according to the actual situation of the vehicle.

Nickel alloy spark plug material is the worst, so the life is the shortest, generally 3-50,000 kilometers to replace once, while platinum spark plug electrode material is better to replace once in 6-80,000 kilometers, iridium spark plug life is the longest in 100,000 kilometers.

The calorific value of the spark plug indicates the balance between heat absorption and heat dissipation of the skirt of the spark plug insulator, and the higher the calorific value. The stronger the balance between heat absorption and heat dissipation, the lower the calorific value of the thermal spark plug.

Generally, the engine with high power and large compression ratio uses cold spark plugs with high calorific value; Conversely, engines with low power and low compression ratios use thermal spark plugs with low calorific value. Generally, the selection of spark plugs is determined by the factory through product finalization experiments, and should not be replaced at will.

Ordinary spark plugs need to be replaced after 30,000 kilometers, platinum spark plugs are about 60,000 kilometers, and iridium spark plugs are recommended to be replaced for about 80,000 kilometers

One is that the spark plug is severely ablated.

The other is that the spark plug has sediment.

1. Steel shell: The lower part of the steel shell is a fine thread, which is used to match with the spark plug hole of the cylinder head, and the upper part has an outer hexagonal nut for installing the spark plug sleeve to tighten or screw out the spark plug.

2. The metal rod is the central electric reed slag electrode. The lower end of the metal rod is in contact with the upper end of the central electrode through the conductor glass, and the upper end of the metal rod is equipped with a wiring nut.

3. There is a high alumina ceramic insulator between the steel shell and the central electrode, so that the central electrode is insulated when energized.
