I am a car novice, how to choose the model for spark plug replacement?

There is a model on the spark plug of the car itself, as long as you choose it according to the original model, you will not go wrong. Moreover, the spark plug brand will also provide an appropriate model query, for example, the official WeChat of NGK spark plug provides ** query, enter the car brand, model, and displacement, and you can match the appropriate spark plug model

There are quite a lot of spark plug models, and the spark plugs of different cars will be distinguished from the material shape and calorific value, and they must be adapted to their own cars, and they must also be replaced regularly in strict accordance with the replacement cycle of the spark plugs, otherwise the engine will be damaged. You can take a look at NGK spark plugs, they have a very high matching rate, and it is relatively easy to find the original matching model.

Learning technology can be considered from your own interests first.

As long as you know how to make money, you don't have to worry about what model to change at all, the people in the car dealership understand.

Replace the spark plug, it must be compared with the model, now on the market different manufacturers factory, different engine models and specifications are different, most of the spark plugs are dedicated to special cars.

Different spark plugs have model differences, such as thread diameter, internal construction features, calorific value, external construction features, thread length, ignition clearance, etc. The corresponding cylinder block of the spark plug distinguished by the model may be different, the length is different, the calorific value is different, and the ignition clearance requirements are also different, so the selection of spark plugs needs to be selected according to the relevant model specifications of the engine, and the appropriate and special spark plugs can be installed normally.

The calorific value and clearance of the spark plug are the most important, such as the calorific value, high-speed engine and low-speed blind land engine, usually the demand for calorific value is not the same, generally high-speed engine, high-power engine, requires higher cooling calorific value, and needs a cold spark plug with fast heat dissipation. At present, there are generally three kinds of calorific value requirements for spark plugs on the market.

There are several types of spark plugs currently available in the market, such as nickel alloy, platinum, iridium, iridium platinum, etc. , and the replacement cycle can vary according to different materials. Generally speaking, the service life of ordinary spark plugs is about 2-30,000 kilometers, while the service life of Youho platinum and iridium grinding materials can reach about 6-80,000 kilometers.

In fact, the spark plug is not universal, many people only pay attention to its material and number of poles when replacing the spark plug, but the calorific value of the spark plug should also be paid attention to. The calorific value of each brand is its corresponding model, so when purchasing, you must pay attention to whether its calorific value matches your model, otherwise it will cause different degrees of impact.

Spark plugs are small, but they play an important role in automobiles. The size of the gap of the spark plug affects the ignition ability and reliability of the spark plug. The spark plug gap is the distance between the spark plug center electrode and the ground electrode.

If the spark plug clearance is too large or too small, it will affect the working condition of the engine to a certain extent.

The calorific value of the spark plug is expressed by numbers, and the calorific value includes nine numbers from 1 to 9, of which 1--3 is the low calorific value, 4--6 is the medium calorific value, 7--9 is the high calorific value, and most of the spark plugs are between 5-7. These numbers are usually in the middle of the model number, such as BP5E S-1 1, then the number 5 is the heat generation of the spark plug.

If you choose a spark plug with different heat generation, it is easy to affect the output of the engine, and even it is possible to scrap the spark plug directly. If the engine continues to run at high speed, the spark plug is easily destroyed due to lack of heat dissipation, so it is very important to choose the right calorific value.

The effects of spark plug gap size are as follows:

The gap is too large: there will be poor ignition, which requires a higher pulse ignition voltage, which is easy to cause insufficient fuel combustion, resulting in high oil consumption, and may also appear in the process of engine shutdown, if the spark plug gap is too large, the spark plug needs to be replaced in time.

The gap is too small: the arc generated is too short, resulting in too weak ignition energy to ignite the fuel in the engine or insufficient combustion, which will lead to power loss, difficulty starting, unstable idling, insufficient power, fast running, etc., which will also increase fuel consumption to a certain extent.

It is not generic, and the original spark plug should be selected when it is replaced, and the spark plug also needs to be selected according to the model.

The first spark plug is to choose the brand, and the second is to choose the model, so the spark plug is not universal.

You can choose a spark plug with good durability or a spark plug with more affordable durability. The Hebi return spark plug is not universal, and the Zen hunger still has to be chosen according to the model of the car.

The car needs to be replaced with a spark plug after a certain period of time, and if the spark plug is abnormal, it may cause the engine to fail in the lighter. Spark plugs are different according to the model of the car.

The spark plug is a small part on the car, although the spark plug is a small part, but the role of the spark plug is indeed very large, the car can not be started without the spark plug, the car mainly relies on the spark plug to ignite the gasoline when it starts, so that the strong kinetic energy generated by the gasoline deflagration can be converted into the power of the car forward. So don't look at the small spark plug, a small spark plug is very important for the car.

If the car is going to replace the spark plug. The first choice is that individuals will choose the more cost-effective. Now the spark plug is different according to different materials, and the service life is also different, and the choice of cost-effective spark plug can not only ensure the quality, but also can cost the least, is the most cost-effective choice; Secondly, choose a spark plug with a good market reputation.

If you want to know what the quality of a spark plug is, we can choose by the market response of this spark plug. Generally speaking, a good spark plug with market reputation is naturally not wrong, after all, the eyes of the masses are bright; Finally, go to the 4S store for replacement. When replacing auto parts, we had better go to the 4S shop of the car to replace, after all, the spark plug replaced in the 4S shop is excellent in terms of quality, service and after-sales, and we are more assured to replace it in the 4S shop.

First, choose a more cost-effective one. When it comes to replacing spark plugs, I will definitely choose the one with the best value for money. After all, the current spark plugs are different due to the material. The life span is also different, and it is most cost-effective to choose the most cost-effective. <>

Second, choose a spark plug with a good reputation in the market. Now there are many kinds of spark plugs on the market, and the quality is uneven, when we replace the spark plugs, it is best to choose the kind of spark plugs with a good reputation in the market. <>

3. Go to the 4S store for replacement. Replacing the spark plug in a 4S shop is a better choice. After all, the spark plug changed in the 4S store is more advanced in quality and better service. Therefore, it is best to choose a spark plug from a 4S store.

I will choose some filter elements that are more efficient, and at the same time, I should pay attention to the material of the spark plug, and pay attention to the safety and stability, it is best to choose the original imported, and to choose the right model.

I choose the right spark according to the brand of the car, so that I can reduce the damage to the car and also make the driving smoother.

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; 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 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 firmly fixed, the spark plug insulator is broken, etc., and it should be adjusted or replaced in time.

Normal family cars generally spark plugs 60,000 kilometers can be replaced, depending on the condition of your vehicle, if the car spark plug head that burns engine oil will become very black, the specific situation is analyzed.

Iridium spark plug life can reach 6-80,000 km. Ordinary resistance spark plugs can be replaced once every 20,000 kilometers, platinum spark plugs can reach 40,000 kilometers, and iridium spark plugs can reach 6-80,000 kilometers. However, this is a theoretical estimate, and the life of the spark plug is affected by many aspects such as engine conditions and driver's operating habits.

If the car body shakes, cannot speed up, or does not catch fire, then the spark plug should be replaced in time.

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

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

3. Iridium platinum spark plug Iridium platinum spark plug uses iridium for the central electrode, which improves the ignition sensitivity of the engine and improves the ignition performance, and the side electrode uses platinum material. The melting point of iridium platinum spark plugs is much higher than that of platinum spark plugs, and it can maintain a stable ignition state well under the condition that the engine continues to run at high temperatures, 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 plug Iridium spark plug The overall material of the iridium spark plug is made of iridium, which is the best performance in the spark plug, 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.

In addition, the service life of the spark plug is affected by the use of inferior gasoline and other factors, the water content of inferior gasoline is high, and the combustion is not complete, and long-term use will make the surface of the spark plug wrapped with carbide, resulting in the inability to ignite. 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.
