How often do you need to replace your vehicle s spark plugs?

Although the ignition coil is not worth mentioning in the car, this thing has a great effect on the starting and operation of the car, so that we can not underestimate the existence of this gadgetIf the ignition coil in the car is not replaced immediately, the initial service life of the car may be reduced due to the correlation of body temperature, and even in some cases there will be casualties of the staff, so the ignition coil in the car should be remembered to be replaced after a period of application.

This kind of ignition coil is mostly seen in the standard car series, and it is used more in domestic cars. In addition, some precious metal spark plugs have a longer life, and Denso spark plugs are more commonly used at this stage, with strong reliability, and are mostly seen in high- and medium-end car applications, and it is also known as an enhanced ignition coil, which can usually be replaced up and down 60,000 kilometers. In addition, there are also platinum spark plugs, which have a longer service life than Denso spark plugs, and can be used up to 80,000 kilometers or even longer, but in terms of characteristics, they are similar to Denso spark plugs.

There is also a class of ignition coils made of ultra-high-grade materials, platinum spark plugs, which have a service time of more than 100,000 kilometers and excellent characteristics, but they are not commonly used.

Naturally, if you say that the characteristics of your car fuel injector itself are better, the material is made of excellent aluminum goldRelativity in the driving of 90,000 kilometers and then dismantling and replacement may not be a problem, this is based on the ignition coil itself and the decision, and now the better ignition coil is about 100,000 kilometers to carry out a replacement, otherwise, perhaps for the life of the car will be very affected, more serious and even will destroy its own engine.

In fact, not only the ignition coil for the car, but also many other components for the carAfter all, the car itself is a whole, leaving no one will be able to operate normally, so not only to replace the spark plug independently, but also to say that after the necessary time, the car as a whole to carry out a whole body maintenance.

This depends on what kind of spark plug it is, the ordinary spark plug of the general model needs to be replaced once in three to fifty thousand kilometers!

In fact, the spark plug of the vehicle generally needs to be replaced once every three years, because after a certain period of time, this thing will age.

Like the spark plug of ordinary material, the car must be replaced when it travels to 20,000 kilometers, otherwise it will be easy to have problems after a long time.

In general, it may be appropriate to replace the spark plug after 60,000 kilometers of driving.

Of course, if the performance of your car spark plug itself is better, the material is the use of good aluminum gold, relatively after driving 90,000 kilometers and then replace it may be no problem, this is based on the material of the spark plug itself, and now we know that the better spark plug is about 100,000 kilometers to be replaced, otherwise, perhaps for the life of the car will be greatly reduced, serious may even damage their own engine.

The replacement cycle of different types of spark plugs is not the same, and the replacement cycle of ordinary electronic spark plugs is generally replaced once every 20,000 kilometers.

The replacement time of the spark plug should be determined according to its material, the better the material, the longer the replacement time interval, but also according to the road conditions of the vehicle, the quality of the oil, and the carbon deposition of the vehicle.

The most common spark plugs are usually replaced every 20,000 km, while the better platinum spark plugs are replaced every 40,000 km, and iridium spark plugs are replaced every 6 to 80,000 km.

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, and 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 repair shop to remove the half-new spark plug removed from other people's cars to use again.

The ordinary car fire pie is more dusty, and the change cycle is about 30,000 kilometers. According to the different spark plug materials, the replacement mileage is also different: ordinary copper core spark plug replacement mileage; 30,000 km; Yttrium spark plug replacement mileage:

50,000 km; Platinum spark plug replacement mileage: 50,000 km.

The replacement cycle of a car's spark plug depends on the material of the spark plug.

If it is an ordinary nickel alloy spark plug, the car must be replaced after about 20,000 kilometers. If it is a platinum spark plug, it needs to be replaced at about 40,000 km. If the vehicle uses an iridium spark plug, it can be replaced at 680,000 kilometers into the hole.

If the vehicle uses a more advanced iridium-platinum alloy spark plug, then the driving range can reach 120,000 kilometers.

A precursor to the need for a replacement of the spark plug.

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

When starting the car, it is found that it is difficult to start, or even fails to start, which means that the car may have more than one spark plug problem, or maybe multiple spark plugs have problems, and it is necessary to check and replace the fire plug.

2. The acceleration of the car is not smooth.

Due to the large electrode gap of the spark plug, it cannot provide stable ignition energy, resulting in our car not being smooth in acceleration, shivering and empty, and the spark plug needs to be replaced.

3. Carbon deposits appear in the spark plug.

The engine burns oil or burns incompletely, which will cause black grease on the spark plug, which is carbon deposit, which will cause the spark plug to fail to ignite normally, and the spark plug needs to be replaced.

4. The ignition of the spark plug is abnormal.

Remove the spark plug, plug in the sub-cylinder line, and use the motor to start the engine, and find that the spark plug pole jumps out as a blue flame normally. If the spark is weak, red, or the spark is not in the middle of the pole but is jumping around, the spark plug needs to be replaced.

The time to replace the spark plug is different for different materials. For example, the spark plug made of ordinary nickel alloy may need to be replaced once in about 20,000 kilometers. This kind of spark plug is commonly found in low- and medium-sized models, and is used more in domestic cars.

In addition, some spark plugs have a longer life, iridium spark plugs are currently widely used, the stability is relatively strong, commonly used in high-end cars, it is also called enhanced spark plugs, generally can be replaced once about 60,000 kilometers. In addition, there are platinum spark plugs, which have a longer life than iridium spark plugs, and can be used for about 80,000 kilometers or even longer, but if you look at the performance, it is similar to the iridium spark plug. There is also a spark plug made of ultra-high-end material beam, which can be used for more than 100,000 kilometers, and the performance is also excellent, but it is not widely used.

The maintenance master said that of course, these values are not applicable to all situations, and it depends on the road conditions of the vehicle, the quality of gasoline oil, the carbon deposit of the vehicle, etc., which will affect the life of the spark plug. Generally, if the vehicle has obvious symptoms, such as frequent stalling at idle, insufficient engine power, etc., it is recommended to start with the spark plug. It is also relatively simple to see if the spark plug needs to be replaced, you can remove the spark plug by yourself, observe its color, whether the carbon deposition is serious, whether the gap becomes larger, and whether there is air leakage.

1.The flammable mixture is too 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 air filter element 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; For four-stroke hair closure motives, 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 valve tube oil seal hardens or the oil seal lip is worn excessively, which will cause its fitting gap to be too large and lose the sealing effect.

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 can not 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 fixed firmly, and the spark plug insulator is broken, etc., which should be adjusted or replaced in time.

Under normal circumstances, the life of ordinary spark plugs is about 30,000 kilometers, and the life of *** spark plugs is between 6-90,000 kilometers. However, the maintenance interval stipulated by different automobile manufacturers is different, so the replacement interval of the spark plug should also be based on the standard set by the automobile manufacturer, and cannot be extended arbitrarily. Moreover, 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 and other town celebrations. These types of spark plugs have different service life and corresponding replacement mileage, which should be clearly distinguished when choosing.

When you notice an increase in your vehicle's fuel consumption, you can consider whether to replace the spark plugs. Generally, after 2-30,000 kilometers, the repair shop will recommend replacing the spark plug, because the spark plug has not been completely damaged at this time, but the efficiency has decreased. In fact, it depends on the quality of the spark plug.

Ordinary spark plugs can be replaced every 3-40,000 km, and sheet metal and iridium can be replaced every 6-90,000 km. The ** of spark plugs generally ranges from tens of yuan to 100 yuan, and then find a reliable repair shop to install them. The installation process is time-consuming, and the owner can inspect it himself, saving money and avoiding dirty repair shops and reusing half-new spark plugs that have been removed from someone else's car.

When replacing the spark plug, it should be noted that it must be replaced in the case of a cold car, because the spark plug expands when the car is hot, and the bolt and thread are tightly combined, so it is easy to cause the spark plug thread to slip and break when the hot car is replaced; However, spark plugs are easier to replace and disassemble than hot cars, reducing the risk of wire slippage. However, the sliding line is more troublesome, and if necessary, the cylinder must be opened, and the cost will be very large.

The role of the spark plug: the gasoline engine is different from the diesel engine. Due to the high ignition point of gasoline (about 400 degrees), it is necessary to use a forced ignition method to ignite the mixture.

The phenomenon of discharge between the electrodes creates sparks, and the gasoline engine generates power through the timely combustion of fuel and gas mixtures. However, gasoline as a fuel is difficult to spontaneously ignite even in a high-temperature environment, so it needs to be ignited with "fire" to make it burn in time. The spark ignition referred to here is the function of the "spark plug".
