There is no problem with the use of the car, is it necessary to replace the spark plug?

Determine whether to change the spark plug.

Method. 1. According to the relevant classification of spark plugs, in real life, the life of resistance spark plugs is 20,000 kilometers, while the service life of platinum spark plugs with better materials is 4-50,000 kilometers, and iridium spark plugs are 7-80,000 kilometers.

2. The car is idling.

time, with a screwdriver.

Perform a short circuit test on the spark plug (be sure to cylinder by cylinder), listen carefully to the engine speed and the change in sound, if there is not much change from before, it means that the spark plug is normal and there is no need to replace it.

3. There is also the ability to remove the spark plug for color change identification, if it is russet or rusty color, it also means that the spark plug is normal. If there is oil stain, it means that the spark plug has a gap out of balance or a short circuit and needs to be replaced.

4. The burning phenomenon on the surface of the spark plug is very serious, and there are bad phenomena such as rupture and electrode melting, which indicates that the life of the spark plug has reached and needs to be replaced immediately. It is best to change to a little more to ensure the fuel combustion economy performance of the engine.

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 about 80,000 kilometers. Spark plug ablationWhen the owner finds that the top of the spark plug is scarred or damaged, and the electrode is melted or ablated, it indicates that the spark plug has been destroyed, and the spark plug should be replaced.

During the replacement process, the owner can first check the symptoms of spark plug ablation and the change in color. So how can you tell if a spark plug needs to be replaced? 1. See if the engine can start normally, 2. Look at the engine shaking 3. Check the electrode gap of the spark plug, 4. Observe the color, if it 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, the high-voltage line is short-circuited or broken, if the spark plug is seriously ablated, the top appears scarring, black lines, rupture, electrode melting, etc., which indicates that the spark plug has been damaged and must be replaced immediately.

According to different equipment, spark plugs can be divided into many types, and the usage and life are also different. If the spark plug is not replaced for a long time, the car will shake, unable to speed up, or unable to catch fire, so the spark plug should be replaced in time.

Spark plugs are used in automobiles and motorcycles, and their main role is to ignite the engine to ignite the engine cylinders. The spark plug is always in working condition during the operation of the car, so it is an indispensable part of the fuel engine. The service life of spark plugs of different materials is also different, and the spark plugs on the market generally include the following:

1. Resistance spark plugs.

The material of this spark plug is very ordinary, generally used in low-end vehicles, and its electrode material is generally made of copper and nickel alloy, so it consumes relatively quickly when used and needs to be replaced frequently, and the service life of the resistance spark plug is generally about 20,000 kilometers.

2. Platinum spark plugs.

The melting point and hardness of platinum spark plugs are higher than those of resistance spark plugs, and are characterized by long service life, good stability and durability in bad weather, and sparks are also relatively stable, with a service life of about 40,000 kilometers.

3. Iridium platinum spark plugs.

Iridium platinum spark plug center electrode uses iridium to improve engine ignition sensitivity and improve ignition performance, and platinum material is used for side electrodes. Iridium platinum spark plugs have a much higher melting point than platinum spark plugs, and can maintain a stable ignition state well under the condition of continuous high-temperature operation of the engine, and the discharge performance is also very good. Iridium spark plugs are very hard and durable, with a service life of about 6.1 million kilometers.

Fourth, iridium spark plugs.

The overall material of iridium spark plug is made of iridium, which is the best performance in the spark plug, and this material is characterized by high hardness, high melting point, high corrosion resistance, and is the most wear-resistant material. It is more suitable for the use of high-power engines, and the electrodes are not easy to be damaged and melted in an ultra-high temperature environment, and the general service life can be as high as 680,000 kilometers.

The service life of the spark plug is different according to the different materials, the replacement time is also different, in addition to the impact on the service life of the spark plug are the use of inferior gasoline and other factors, the inferior gasoline has a high water content and is not completely combusted, and long-term use will make the surface of the spark plug wrapped with carbide, resulting in the inability to ignite and other situations. Therefore, in daily use, it is necessary to pay attention to the quality of the car's oil and the number of kilometers, and replace the spark plug in time.

As we all know, a spark is a very important component in an engine. The engine relies on spark plugs to ignite a mixture of gasoline and air to generate power. Spark plugs work in a high-temperature and high-pressure environment for a long time, and if they are not checked and replaced in time, they may seriously affect the engine.

Next, let's learn about spark plugs together!

If the spark from one of the engines breaks, the tank will not work. In this case, a 4-cylinder engine can become a 3-cylinder engine, a 3-cylinder engine can become a 2-cylinder engine, and a car can become a motorcycle. Insufficient engine cylinders can lead to problems such as insufficient power, significant engine shake at high, medium and low speeds, increased fuel consumption, and increased engine wear.

The work of a gasoline engine is divided into suction, compression, combustion, exhaust four-stroke, and circulation. If the ignition time of the spark plug is not accurate, and the compression stroke does not reach the ignition position after the engine sucks in the oil-gas mixture, it has ignited, which may cause the engine to be ignited. Knocking can cause problems such as decreased power, increased fuel consumption, increased noise, and, in more severe cases, shutting down or damaging the engine.

The temperature in the engine cylinder is very high, and the damaged spark has not been replaced for a long time or a bad spark is used, and the spark electrode will melt during the operation of the engine, falling into the engine cylinder, forming a cylinder.

Even if the spark is not replaced for a long time, the electrodes can create carbon deposits that require higher temperatures, and a more concentrated oil-air mixture ignites the engine to increase fuel consumption. Sparks are so important that they should be checked or replaced depending on the time of repair. It's also important to choose the right spark.

Whether the calorific value of the spark matches the engine, whether the sparks with different electrodes are in line with your vehicle condition and driving habits, and the blind pursuit of expensive sparks will not help improve engine performance.

It will affect the engine of the car, it will also affect the chassis of the car, and it will also affect the brakes of the car, and it will also affect the service life of the car, and if the situation is very bad, it will bring a lot of unnecessary trouble to yourself, so I think there is a lot of harm to the car.

There is a particularly serious hazard, which will cause foreign objects to enter the intake cylinder, and it is easy to have cylinder leakage, which may affect the normal operation of the engine, and may not ignite and do not affect the normal driving of the vehicle.

If the spark plug is not replaced, it is not conducive to the service life of the car, it will damage other parts, it will seriously affect the engine, it will not have a good experience, and it is not conducive to the long-term operation of the car.

The harm to the car is very large, first of all, it is likely to affect the performance of the spark plug, will affect the performance of the engine, and may affect the normal driving, the damage to the car is very large, the cylinder is likely to leak, if the spark plug is not replaced regularly, there is a great safety hazard.

The spark plug is a more important part of the engine, and if it is not replaced for a long time, it will affect the power and fuel economy of the engine.

The spark plug is a wearable part, and the gap between the electrodes of the spark plug will become larger after a long period of use, which will affect the ignition energy of the spark plug. Carbon deposits will also occur after the spark plug electrode is used for a long time, which will also affect the ignition of the spark plug.

If you do not change the spark plug for a long time, the power of the car will decrease, and the fuel consumption will increase, so you need to replace the spark plug on time. Lead stupidity.

Precautions for replacing spark plugs:

1. After removing the spark plug, you need to paste the hole where the spark plug is installed with a sticker, which can prevent foreign objects from entering the cylinder.

2. When installing the spark plug, it is necessary to tighten the pin cover according to the specified moment. If tightened too tightly, the spark plug may break. If it is not tightened, the cylinder may leak.

3. When choosing a spark plug, you should choose a model that suits your car engine, and the spark plug has different calorific values and clearances.

When replacing the spark plug, you can choose the spark plug of the rare metal electrode. This spark plug lasts longer.

The spark plug needs to be replaced regularly, and the maintenance manual on the vehicle says the mileage or time of the spark plug replacement, and the riders can replace the spark plug according to the provisions of the maintenance manual.

<> "There are many car owners who do not know and attach great importance to spark plugs, and there will be overtime replacement and long-term non-replacement. So does not changing the spark plug have an impact on the car?

Influential. When the life of the spark plug reaches the end of its life, its discharge gap will be too large, which will affect the ignition effect of the car, reduce the power of the engine and increase the fuel consumption of the car.

If it is more serious, there will be engine idle shaking, shaking at low speed, weak acceleration, cold car is not good ignition and other fault phenomena, then it is necessary to replace the spark plug, because after this kind of failure, it means that the combustion is not good, and a large amount of carbon deposits will be formed, which will lead to a large failure.

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. For example, the early slippery fruit is a platinum brigade Wang Jin spark Lu Zhen Lasai, which needs to be replaced at about 40,000 kilometers.

If the vehicle is using an iridium spark plug, it can be replaced at 6 80,000 km. If the vehicle uses a more advanced iridium-platinum alloy spark plug, then the driving range can reach 120,000 kilometers.

If the spark plug is not replaced after a long period of use, carbon deposits will be generated, which can easily cause problems such as difficulty in engine starting, vehicle shaking, weak acceleration and increased fuel consumption. In serious cases, it will also cause the incomplete combustion mixture to enter the exhaust pipe, and after secondary combustion, the exhaust pipe will burn red and damage the three-way catalytic converter. More information about spark plugs and how to use them are checked below:

1. The replacement cycle of the spark plug is related to its material, the better the material, the better its performance. Platinum cores and iridium cores have good oxidation resistance and high metal stability, so they have a longer service life. 2. The inspection of the use of spark plugs in the group answer has roughly three points:

1) Check whether the metal head on the top of the spark plug is bent or bent for ablation and deformation. (2) Check whether the ceramic insulator has yellow-brown plaques, which is a manifestation of leakage of the insulator. (3) Check the carbon deposition of the spark plug electrode, the edges and corners of the electrode and the gap.

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, indicating that excess oil enters the cylinder, it Huixiang 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 lip of the acacia oil seal is worn excessively, it will cause its fitting gap to be too large and lose its 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, Changbiyou ignition coil and electronic ignition inside, generator output end and ignition coil losing end of the wire connection loose, as well as incorrect ignition advance time, such as improper timing, will affect ignition performance, and ignition performance is poor, will 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 firmly fixed, the spark plug insulator is broken, etc., and it should be adjusted or replaced in time. 5.

If the crankcase oil is filled too much, if the ventilation pipe is blocked, the pressure in the crankcase will increase and cannot be balanced.
