When the fuel injector fails, it will lead to an increase in carbon deposition in the engine, unstable idling, increased fuel consumption, weak acceleration, difficult starting, excessive emissions, etc., and in serious cases, it will cause the fuel injector to be blocked, and then damage the engine.
The injector is a simple solenoid valve. When the solenoid coil is energized, a suction force is generated, the needle valve is sucked up, and the nozzle hole is opened. The fuel is sprayed at high speed through the annular gap between the shaft needle and the nozzle hole at the head of the needle valve, forming a mist, which is conducive to full combustion.
As one of the key components of the EFI engine, the fuel injector will seriously affect the performance of the engine.
The reason for the blockage is that the carbon deposits in the engine are deposited on the injector, or the impurities in the fuel block the injector channel, and the injector is blocked, pay attention to the following points;
First, don't coax the throttle with a big foot, especially if the fuel injector is blocked, which will cause the fuel injector to be completely damaged.
Second, the fault light is not good for a long time, and the fault light will be reported after a certain number of times, indicating that the car is not burning well before, which may be oil or oil deterioration and there is no good fuel to burn.
Third, in the case that the oil circuit is not cleaned and improved, cleaning the throttle will lead to increased air intake, thinning of the mixer, and the vehicle will shake at idle, and the throttle will be channeled.
Fourth, repairing a car does not mean that it will be good, and repairing it may aggravate problems in other places. This is normal and requires the use of elimination.
Fifth, in the case of poor combustion, shaking, and scurrying, the first thing to clean the oil circuit is, and not to rush to replace the accessories.
This is very easy to deal with, encounter such a fault code, after the detection, it has been determined that the fuel injector is blocked, then the traditional way is to disassemble the fuel injector to replace, not to mention the replacement of the labor costs, we will say the reason for this, we have to first figure out why it will be blocked, will be after the replacement, to avoid the later blockage, after all, the replacement cost is very high, you replace the plug again, is it to consume a lot of cost.
There are two types of blockage, one is the external blockage caused by ash and carbon deposits on the outside of the fuel injector in the combustion chamber, and the other is the internal blockage caused by the oil in the oil circuit. Both of these blockages can be cleaned and unblocked by PNF-based additives. But be sure to use effective additives.
Don't wait for the car to have a problem before thinking about changing the parts, the cost outweighs the loss.

This is not allowed, because the carbon deposit of the fuel injector is not on the surface, he is in the position of the injection needle valve, which does not mean that it can form carbon deposits as thick as a spark plug, if the fuel injector is not cleaned for a long time, the impurities in the gasoline will gather here, which may lead to poor atomization of the fuel injection.
-
This is generally not possible, spark plugs, no carbon deposits do not mean fuel injectors, no carbon deposits are recommended to clean up, ** is not very expensive.
-
Hello, if there is no carbon deposit in the spark plug, it means that the carbon deposit in the whole cylinder is not very serious, but whether the fuel injector has carbon deposit or not needs to be checked separately to know.
-
This is not necessarily, and generally speaking, it is necessary to check the fuel injector separately, and there may be carbon deposits in the fuel injector hole.
-
Hello, there is no carbon deposit on the spark plug of the car, and it is impossible to tell whether the fuel injector has carbon deposit. Personally, I recommend that you clean the fuel injector.
-
Hello, the spark plug has no carbon deposit, it does not mean that the fuel injector has no carbon deposit, and there is no carbon deposit in different parts, so it is still necessary to check whether the fuel injector has carbon deposit.
-
This removed spark plug has no carbon deposit, and it cannot be judged that the fuel injector has no carbon deposit, and the two are not in the same position.
-
Hello This can't be judged, the fuel injector and the spark plug are two different things, it is recommended to check it out.
-
This is not judged at the same time, this can only mean that the spark plug has no carbon deposit, and the others need to be re-checked.
-
Hello, this can only judge that the combustion of the spark plug is better, and the fuel injector needs to be disassembled to be determined.
-
You draw it well, the absence of a group does not indicate that the fuel injector is not deposited, and there is no carbon deposit, so you still have to remove the fuel injector to take a look.
-
See if it is direct injection in the cylinder, if so, it can be judged like this.

Summary. There is no carbon deposit in the spark plug, and the carbon deposit is usually the carbon deposit generated by the combustion chamber in the cylinder.
Does it matter if the carbon in the area of the spark plug is not cleaned?
There is no carbon deposit in the spark plug, and the carbon deposit is usually the carbon deposit generated by the combustion chamber in the cylinder.
It is necessary to clean the carbon deposits in the combustion chamber. After the car runs for a long time, the carbon deposits in the air intake, valve and combustion chamber will increase, and these carbon deposits adsorb fuel when the car is cool, and release fuel when the car is hot, and the phenomenon of high fuel consumption of the cool car is not easy to get on the scene, which leads to the deterioration of engine performance, and the undesirable phenomena such as idle shake, poor acceleration, increased fuel consumption, and excessive exhaust gas need to be cleaned at this time. The reason for the formation of carbon deposition is that although today's engine technology is quite advanced, the efficiency of the combustion chamber is only 25%-30%, so the carbon deposition is mainly caused by the phenomenon caused by the machinery itself, as well as the poor quality of gasoline, generally from the refinery, the quality may not be the same, so the degree of impact is slightly different, but if solvent oil or illegal oil is used, it will lead to more serious carbon deposition.
After the car has been driven for a while, a certain amount of deposits form in the fuel system. The formation of sediment is directly related to the fuel of the car: firstly, the gasoline itself contains gums, impurities, or dust and impurities brought in during storage and transportation, etc., which accumulate over time to form sediments similar to sludge in the fuel tank and inlet pipe of the car; The second is due to the oxidation and polymerization of unstable components such as olefins in gasoline at a certain temperature, forming colloidal and resinous viscous.
These sticky substances are deposited in areas such as injectors, intake valves, combustion chambers, (cylinder heads and rarely tops) and become hard carbon deposits. In addition, these deposits are exacerbated by the fact that cars are often at low speed and idle due to urban traffic congestion.
If you want to clean up the carbon deposits, there is no need to go to the repair shop to clean up, you can directly buy fuel additives to clean up the carbon deposits.

Many cars have carbon deposits on their spark plugs. So you need to check it regularly. If there is a lot of carbon deposits. It's time to replace it.

Is it useful to change the spark plug if the carbon deposit is not treated, and the dirt on the spark plug is mainly carbon and oil. The carbon deposit is deposited on the end face and inner cavity of the shell of the spark plug screw-in part and around the skirt and electrode of the insulator, which is a layer of black or gray-black deposit, and presents a hairy, black, and matte layer of carbon deposit when the carbon is severely deposited. Oil contamination is mainly found around the end face of the housing and in the skirt of the insulator screwed into the cylinder by the spark plug.
The spark plug is seriously oily and carbon deposit, which is equivalent to reducing the spark plug electrode gap, so when the secondary voltage has not risen to the spark plug breakdown voltage, the leakage is generated through carbon deposition, which causes the secondary voltage to drop and cause ignition difficulties. For this reason, the car should be inspected every 5,000 to 10,000 km and cleaned if dirt is present.

<> "Spark plug, it is no exaggeration to say that every car is inseparable from it, although the small part of the spark plug is not as casual as the machine filter, but it also has a service life. So do spark plugs have carbon deposits that need to be replaced?
When inspecting the spark book jujube liquid plug, if there is more carbon deposit, the spark plug needs to be replaced in time. Because the spark plug has carbon deposits, it is easy to cause failure, then the fuel consumption of the car will become higher, the power will decrease, and even the normal ignition will not be possible, and the engine will not be able to run normally.
The spark plug will produce carbon deposits with the increase of service time, and if the carbon deposits can be cleaned regularly, it will be of great help to the service life of the spark plug and the normal operation of the engine. If the spark plugs are not cleaned regularly, it is easy to cause serious carbon deposits, which will eventually affect the service life of the engine. However, if the spark plug has been used for a long time beyond its useful life, or has been damaged, cleaning is not necessary and should be replaced.

Pros and cons of changing the 12-hole fuel injector - pros.
1. Better power and more intense acceleration.
2. The engine runs more stably, and the shaking and noise become smaller.
3. The gear is smooth, the acceleration is coherent, and the throttle response is better.
If the replacement is not done correctly, problems may occur.
Pros and cons of changing the 12-hole fuel injector - cons.
1. Sometimes there may be unstable idling, jitter and other phenomena.
3. If the operation is not correct, it will bring very serious consequences, such as: the air-fuel ratio is too thin, which will cause high temperature in the cylinder, and the cylinder will burst in serious cases; If the air-fuel ratio is too thick, it will cause fuel consumption, weakness, carbon deposition, etc.

As the terminal of the ignition system, the spark plug is in direct contact with the fuel, and the fuel will also be formed by carbon deposition during the combustion process. Therefore, a small amount of carbon deposition is normal, and a large amount of carbon deposition will affect the power output and increase fuel consumption, which needs to be replaced in time. If you find that the oil consumption is serious, it can also be considered that the spark plug carbon deposition caused by burning the engine oil is serious.
The solution to burning the oil.
In the habitual thinking of car enthusiasts, they always think that burning engine oil should be overhauled, so that they not only have to bear high maintenance costs, but also bear the unpredictable risks and depreciation losses brought about by the overhaul. Destroy the airtightness and precision of the engine. And there is a possibility that the engine oil will burn again after tens of thousands of kilometers, so overhauling the engine is not sustainable.
Now the no-dismantling technology has been very mature and gradually accepted by the majority of car owners. In particular, the non-destructive repair products containing PNF patented technology have completely gotten rid of the technical shackles of the operation of the auto repair shop, and the owner can operate it himself without removing a screw, and the piston ring is repaired and released during driving, and the effect is remarkable.
-
Yes, the details are as follows: 1. The main reason for excessive carbon deposition in the spark plug is that the phenomenon of burning engine oil will lead to this situation; 2. If a large amount of carbon is found in the part of the motor after removal, it needs to be cleaned or replaced, otherwise it will affect the normal ignition of the spark plug; 3. If it is serious, it will also affect the power of the vehicle, so if there is a condition, it should be repaired and replaced as soon as possible; 4. In case of emergency use, we can use sharp things to cut off these carbon deposits, and there is no big problem in continuing to use them.
-
The spark plug will not block the fuel injector if it has more carbon deposits, which will make the driving weak and difficult to take a taxi.
-
It will not cause the fuel injector to be blocked, the spark plug has too much carbon, it is not good to take a taxi in the morning, and the fuel consumption is very high, and the acceleration is very slow.

Thank you. And whether it has anything to do with the quality of gasoline.
Hello, dear, this must have something to do with the quality of the oil, <>
Generally, the oil is not good, and there will be too much carbon deposit, because the rapid combustion will be directly discharged, and the remaining debris will go to the cylinder block.
The carbon deposits of the spark plug can be cleaned, but if the sinter reaches a certain point, it will need to be replaced. >>>More
Warm up for 5 minutes, rest for 10 minutes, heat up for another 15 minutes, and then twist again. Thermal expansion, cold contraction for a while to loosen the carbon deposits of the silk teeth, and then thermal expansion begins to twist, and it is easy to unscrew it. If you still feel that it is very difficult to twist it, you can let the sleeve sleeve on the spark plug not be removed, so that the spark plug is cooler than the cylinder block, and the spark plug is faster to cold and shrink, so that it will be easier to unscrew it, and if it is not good, you can warm up the car and cool the car again. >>>More
What does it mean to graft a high-pressure cap with a spark plug? If the spark plug is inserted into the high-voltage cap to test the fire, the metal part of the spark plug should be placed on the unpainted metal of the engine shell or frame, if the high-voltage spark is scattered or scraped at this time, it may be caused by the leakage of the spark plug, high-voltage cap or high-voltage wire.
Hello subject, the engine has just started, you can directly touch the spark plug shell with your hand to compare its temperature to diagnose, the higher temperature works normally, otherwise there is a fault. The temperature of the porcelain surface of the hot engine is very high, do not touch it with your hands, you can keep the engine running at idle speed, touch the high-pressure divider of each cylinder with your thumb and index finger in turn for a few seconds, and judge which cylinder's spark plug is faulty according to the feel. The normal working high-voltage distribution line is obviously pulsating when touched by hand, and the faulty high-voltage distribution line feels that the pulsation is not obvious, no pulsation, or the pulsation is intermittent. >>>More
Spark plugs play a vital role as the end component of the engine ignition system. The calorific value of the spark plug refers to an index of the heating and heat dissipation capacity of the spark plug, and the amount of heat emitted by itself is called the calorific value. >>>More
