What should I do if the carbon deposition in the spark plug is serious, and what is the cause of the

The carbon deposits of the spark plug can be cleaned, but if the sinter reaches a certain point, it will need to be replaced.

The causes of carbon deposits are similar to those in other parts

1) The quality of the oil is not good.

2) There is more driving at low rpm or idle.

3) The quality of the spark plug.

So how to clean, if the carbon deposition is not serious, remove the spark plug and soak it in the cleaning solution to remove the carbon deposition, you can clean it well, after cleaning, the spark plug will restore the original metal luster, and the cleaning solution is very black.

How to prevent or slow down carbon deposition in spark plugs.

1) Use quality assured fuel.

2) Have good driving habits.

3) You can choose the best fuel additives for long-term use.

Finally, note that spark plugs have a service life and still need to be replaced after a certain period of time.

The residue of substances in the fuel injector, throttle, oil pipeline, spark plug, cylinder head, inner wall and other parts caused by insufficient combustion of gasoline in the cylinder, and then the black gum produced by the repeated high temperature action of the engine is called carbon deposit.

One of the reasons for carbon deposition is that the fuel is not completely burned and adheres to various parts of the engine, which can form carbon deposits over time. The main function of additives is to drill into the pores of carbon deposits with strong surface activity, destroy their structure, and gradually dissolve these carbon particles from the metal surface, and then discharge them through the exhaust gas after burning with the fuel at high temperature.

The increase in carbon deposits in the car will lead to insufficient combustion of the engine, resulting in an increase in fuel consumption and a long time when the car failure light is on.

Ways to slow down the formation of carbon deposits:

1.Use high-quality fuel. Because the main components of carbon deposits are wax and colloidal deposition in the fuel, the lower the colloidal content in the fuel, the better. But we can't change the quality of the fuel, but we can choose not to add unidentified cheap fuel.

2.Avoid driving at low speeds for long periods of time. If necessary, the high speed can be pulled at a regular time. The principle of removing carbon deposits at a high speed is to speed up the airflow, which can carry away a small amount of carbon deposits that are not firmly attached. The combustion temperature is increased so that part of the carbon deposits in the cylinder are burned.

carbon deposition hazards; If the carbon deposit is not cleaned for a long time, the operation of the whole vehicle will be caused, the internal channel of the engine will be blocked by carbon deposits, the engine power will become worse, and the occurrence of fuel consumption, abnormal engine noise, and unstable idle speed will occur, thereby reducing the power of the automobile engine, increasing fuel consumption, and causing the combustion rate to be too low. If you do not clean up the carbon deposit in time, it will not only cause a certain degree of harm to the car, but also the harm to the environment, modern society pays attention to energy conservation and emission reduction, and exhaust emissions must not exceed the standard, so we should pay attention to this problem.

Usually 5000 kilometers with effective PNF fuel additives to clean the overall oil circuit carbon deposits, a long time not to clean up the carbon deposits will cause the operation of the whole vehicle, so that the internal channel of the engine is blocked by carbon deposits, the internal fuel injection of the car is not smooth, so that the engine power becomes poor, thereby reducing the power of the car engine, increasing fuel consumption, and the combustion rate is too low.

Let's talk about buying a car, using a car, maintaining a car, and repairing a car.

If the carbon deposition of the spark plug is not very serious, you can use some carbon deposition cleaning products, remove the spark plug and clean it with a cleaning product.

If the carbon deposition of the spark plug is severe, it is recommended to replace the spark plug with severe carbon deposition. When replacing, it is not that the more expensive the spark plug, the better, but you still have to choose according to your own engine.

The spark plug is an important device for automobile ignition, and it is also one of the spare parts that often need to be replaced on the vehicle. However, the replacement of spark plugs is generally based on the material, for example, the spark plug made of cheap nickel alloy is about 20,000 kilometers to replace; The high-grade platinum or iridium spark plug has a theoretical life of about 100,000 kilometers.

1. The engine runs idle for a long time. When the engine is idling, the mixture is thick and the combustion is incomplete, and the engine can not effectively use the exhaust inertia to exhaust, resulting in the increase of residual exhaust gas in the cylinder, and a large amount of accumulation on the spark plug, resulting in excessive carbon deposition in the spark plug.

2. Excessive wear between the piston and the cylinder wall. When there is excessive wear between the piston and the cylinder, it will not only cause poor cylinder compression, but also cause the crankcase lubricating oil to go up. In this case, not only will the calorific value of cylinder combustion be reduced due to poor engine compression, but the spark plug will not be able to clean itself; At the same time, the lubricating oil from the crankcase cannot fully participate in the combustion, and it is also deposited on the spark plug, forming carbon deposits.

3. The valve oil seal is damaged. When an engine's valve seals are damaged, it can cause lubricating oil to escape into the cylinders. When the lubricating oil enters the cylinder due to the damage of the valve oil seal, the lubricating oil is not only wasted, but also the spark plug fouling is accelerated due to the poor volatility of the lubricating oil, incomplete combustion and the large amount of gum in the lubricating oil.

When spark plugs have heavy carbon and oil build-ups, they can usually be used after removal, but their effectiveness and life are reduced.

Another reason is that the damper is often open, resulting in insufficient combustion.

Insufficient combustion or burning of engine oil is related to car habits. The empty gas pedal and the speed of the car cannot go up and down, causing the car to drown. Excessive air-gas mixture enters the cylinder, resulting in insufficient combustion.

The problem with gasoline It is advisable to use gasoline with a high grade.

Too many impurities in gasoline are caused.

In addition, lubricating oil is also related, it is recommended to use the products of regular and well-known manufacturers, and the standards must be higher than those stipulated by the automobile factory.

Hello! There are several causes of carbon deposition in spark plugs:

1. The gasoline added to the car does not meet the requirements.

2. The phenomenon of engine oil burning engine oil.

3. The internal combustion of the engine is insufficient. If mine is helpful to you,! Zhengzhou! Northern! School!

1.Driving repeatedly for short distances and driving without the engine being warmed up.

2.Missed ignition.

3.Wrong mixing ratio (overly concentrated gas mixture).

The first case is more common.

Concentrate on spark plugs, keep improving, and give back to our customers with heart.

1. Washing, you can use some carbon deposition cleaning products to touch, remove the spark plug, and clean it with cleaning products, which is very convenient.

2. Another way is to replace the spark plug with serious carbon deposits. However, when replacing, it is not necessary to say that the more expensive the spark plug, the better, or according to your own engine to choose the package, otherwise it will also cause engine failure.

The spark plug has carbon deposits, this is because the spark plugs are often discharged, due to long-term discharge, the spark plugs are equivalent to being clicked all the time, and carbon deposits will naturally occur after a long time, which is also unavoidable.

The remaining part of the unburned will accumulate on the spark plug electrode and carbonize, which will lead to the abnormal ignition of the flower plug until it is damaged by carbon.

The reasons for the excessive concentration of the combustible mixture are generally the high oil level of the carburetor, the blockage of the main air volume hole of the carburetor, and the serious blockage of the air filter element. 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 over-concentration of the combustible mixture. In the ignition system, the magneton demagnetization, the ignition coil (high-voltage pack) and the electronic igniter internal "false short circuit", the generator output end and the ignition coil at the end of the conductor connection loose or "false tie iron", as well as the incorrect ignition advance time, such as improper timing, will affect the ignition performance, and poor ignition performance will directly cause spark plug electrode carbon deposit.

In either case, as long as the oil enters the combustion chamber to participate in combustion, a large amount of carbon deposits will be generated on the combustion chamber and the spark plug, and the carbon deposits on the electrode and the porcelain insulator will produce hot spots, so that the spark plug will be ablated; The carbon deposit on the side electrode will be conductive due to moisture, so that part or all of the high-voltage current and the spark plug will be iron, resulting in weak or no fire, which will make the engine unable to run normally or not work.

Rinse with detergent, toilet cleaner or white vinegar.

It has an impact on the engine, and the lack of power shakes the acceleration and cleans up the carbon deposits.

The reasons for carbon deposition in spark plugs are: 1. Improper selection of spark plug models. 2. The mixture is too thick or there is too much lubricating oil in the mixture.

3. The engine starts frequently or often for a long time. 4. The engine runs at low speed for a long time. 5. There is too much lubricating oil in the crankcase.

6. The piston ring is worn too much. 7. The ignition time is too late.

3. The engine starts frequently or often for a long time. 4. The engine runs at low speed for a long time. 5. There is too much lubricating oil in the crankcase.

6. The piston ring is worn too much. 7. The ignition time is too late. When this substance completely covers the surface of the insulator, it will gradually decrease to the point of destroying the insulation ability between the electrodes of the spark plug and affecting the flashover of the spark plug.

In order to avoid carbon deposition in the spark plug, attention should be paid to avoid long-term low-speed and low-load operation; Increase idle speed and reduce idle run time; Avoid ultra-high-speed and overload operation; Fuel oil should maintain a certain level of purity; Correct selection of the type of spark plug; Avoid rapid acceleration, sudden deceleration, etc. In this way, all kinds of dirt accumulation of spark plugs can be effectively controlled, the service life of spark plugs can be prolonged, and the work efficiency of the engine can be improved.

CarPlay is an in-vehicle system released by Apple in the United States, which seamlessly combines the user's iOS device, iOS experience and dashboard system. This is not respected by many fruit fans. In the above cases, after the user connects the mobile phone to the Mazda CX4 through the data port, the mobile phone will automatically prompt Siri to turn on, which means that CarPlay will be automatically launched in the interface between the car and the mobile phone.

Once the connection is successful, most of the basic functions of the iPhone can be used through the car's control panel. If the main interface of the car owner does not start carplay, the user needs to tap the carplay icon on the phone to start the system. After a successful start-up, users can access a range of human-machine features, including Siri voice assistant tools, iTunes****, Apple Maps, and text messaging, directly from the car's control panel.

Through the voice function, the driver can directly touch the driving control panel in the car, just like touching a mobile phone, which is convenient and fast.
