What is the carbon deposit of the car? How does carbon deposition in a car come about?

It can be washed, three ways.

1. Remove it and wash it.

2. No disassembly and cleaning.

3. Clean it with a cleaning agent in the gasoline.

4 There are many reasons for this problem, personal driving habits, and there is the same place to drive, you can run a high speed, I hope it will be useful to you.

Car carbon deposition has always been the most headache in the maintenance of car owners, car carbon deposition not only causes high fuel consumption, but also easy to wear engine parts, it is more troublesome to clean up, how to effectively solve the big problem of car carbon deposition, which requires us to develop good driving habits in the daily driving process. Often run the road with relatively large dust, the dust suspended in the air will be sucked into the cylinder, which will accelerate the wear of the piston group and the cylinder, which will produce carbon deposits, it is recommended that the air filter should be replaced every 10,000 kilometers, and it should be cleaned up from time to time. Frequent idling will reduce the airflow in the engine, so that the carbon deposits in the engine cannot be blown away, so that the carbon deposits are deposited; In addition, the longer the idle time, the slower the engine temperature, and the slower evaporation rate of gasoline injected into the back of the valve, which also produces carbon deposits.

At the same time, if you run at high speeds, you can use the high air flow generated at high speeds to blow away carbon deposits in the engine, and you can also reduce carbon deposits by increasing the speed of gear shifting. The main component of carbon deposition is the formation of impurities in gasoline, and the formation of carbon deposition in gasoline with high cleanliness will be poorer, and the life of the engine will be prolonged, which is also the most effective and comprehensive method. If it is a turbocharged engine, do not turn off the engine immediately after climbing or high-speed driving, and turn off the engine after a few minutes of idling.

In fact, "carbon deposit" is not actually "charcoal", but a mixture, which is the colloidal matter left by oil, dust, debris and other debris when the engine works for a long time, and we usually call these colloids "carbon deposit". As the core component of the car, it is recommended that the engine must be maintained on time and do not use inferior lubricating oil, so as not to weaken the performance of the car.

Car carbon deposition is mainly due to fuel impurities and unclean air mixed combustion is not completely generated, there are also bad driving habits, such as large throttle and so on are the causes of carbon deposition, so we must pay attention to maintenance, regularly clean up the carbon and maintain the car!

Carbon deposition includes two concepts:1One concept is the carbon deposition of the engine

During the working process of the engine, the unsaturated olefins and gum in the fuel are produced at high temperatures. 2.The second concept is carbon deposition in EDM, which should be avoided as much as possible in EDM, especially in precision mold processing.

Carbon deposition is a manifestation of abnormal EDM in the spark machine. It can be clearly seen from the sketch diagram of the general engine: the source of power is the mixture, which must enter the combustion chamber through the intake valve; A small part of the gasoline will adhere to the intake valve, in the case of high temperature of the engine, the gasoline can not be burned completely hydrocarbon, paraffin, gum will be burned into glue carbon, if the injector has dirt, the sprayed gasoline atomization state is not good, gasoline and air are mixed unevenly, will increase the amount of gasoline condensed in the intake valve.

The use of automobiles will produce carbon deposits.

More carbon deposition will affect the air-fuel ratio.

Why is carbon deposited generated? This is because the fuel itself contains gum, impurities, dust, moisture, etc., which accumulate over time to form sludge and other deposits in the fuel tank, oil inlet pipe, etc.; Secondly, due to the oxidation and polymerization reaction of unstable components such as olefins in gasoline at high temperatures, colloidal and resinous viscous substances are formed, which stay in the fuel injector, air intake valve and other parts, and the deposits will become hard carbon deposits when burned.

In addition, traffic congestion, cars are often at low speed and idling, which can aggravate the formation and exacerbation of carbon deposits and sediments. If the carbon deposit is not cleaned in time, the carbon deposit and sediment will block the injector needle valve and valve hole, resulting in the intake valve not being closed tightly, the cylinder pressure dropping or even tempering, resulting in unstable engine idling, increased fuel consumption and deterioration of exhaust emissions. Carbon deposits on the piston top and cylinder head can easily cause local overheating of the combustion chamber and gasoline preheating, resulting in engine knocking and other failures.

These failures can shorten the life of the engine.

How to clean up the best way to clean up carbon deposits in automobiles.

Generally, the commonly used methods are: dismantling and washing, hanging bottle cleaning, and fuel additives.

1. Dismantle and wash. This method is very direct and rude, but it is generally sent to the 4S store for disassembly, the disassembly of the engine is more complicated, no matter what parts will affect its performance more or less every time it is disassembled, you need to ask a professional master to disassemble. The carbon deposits in the engine can be seen directly when dismantled and washed, and the cleaning will be relatively clean.

However, the cost will be relatively high, and it will also require technology.

2. Hanging bottle cleaning.

This method is also relatively common, the hanging bottle is to discharge the cleaning agent into the air intake, dilute and soften the carbon deposit to turn it into a slurry, and then burn it from the cylinder to discharge. Generally, the cleaning objects include the intake tract, throttle, intake valve, fuel injector, cylinder inside, etc., but the effect is not as direct and obvious as dismantling and washing.

3. Fuel additives.

One of the causes of carbon deposition is that the fuel burns insufficiently, which adheres to various parts of the engine and forms carbon deposits over time. The main function of additives is to drill into the pores of carbon deposits with the help of strong surface activity, destroy their structure, and gradually dissolve these carbon particles from the metal surface, and then discharge them through exhaust gas after burning with fuel at high temperatures. Effective fuel additives such as PNF stock solution are non-corrosive, will not clog ternary, and have a relatively high level of safety.

1. What is carbon deposit?

Carbon deposits are deposits that occur when fuel and lubricant are mixed with blow-by gas and are incompletely combusted.

The main components are hydroxy acid, asphaltene, tar, etc., and the formation of deposits is directly related to the "fuel" and "lubricating oil" of automobiles.

If you don't pay attention to the oil and driving habits for a long time, the wax and gum in the gasoline will accumulate thicker and thicker, and carbon deposits will be formed when it hardens after repeated heating. If the engine burns oil, or if the gasoline is of poor quality and has more impurities, the valve carbon deposits are more serious and form faster.

2. Ways to slow down the formation of carbon deposition:

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 pulling high velocity to eliminate carbon deposits is to speed up the air flow, which can take 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.

3. The method of cleaning up automobile carbon deposits is as follows:

1. Engine dismantling and cleaning: In terms of effect, engine dismantling and cleaning is undoubtedly the most effective way to clean up carbon deposits, but the whole process requires a lot of time and energy. The engine needs to be disassembled, and then used detergent, ultrasonic, etc. to completely and thoroughly remove the carbon deposits on the parts, of course, the most expensive.

2. Car hanging bottle: hang a bottle-shaped tool above the engine, then pour the detergent into the bottle tool, and introduce it into the engine through the catheter to achieve the purpose of cleaning carbon deposits. However, if the engine has a high level of carbon deposit, this method can lead to blockage or damage to the three-way catalytic system.

3. Machine washing: inject the cleaning agent into a machine, and then touch the combustion chamber with machine pressure, let the cleaning agent react with the carbon deposit to dissolve, and then pump out the waste liquid. This method has a good effect on some serious carbon deposits, and there is no need to disassemble the engine, but the cost is higher, and the oil needs to be changed after cleaning.

4.Clean fuel additives: Proper addition of fuel additives can do a good job of preventing carbon build-up, but only if you choose the right fuel additives.

As long as the engine is powered by gasoline, carbon deposits are inevitable. Because the so-called carbon deposition actually refers to the gasoline remaining inside the engine, after a long time, it will form a gelatinous substance, which is carbon deposit. Still, some habits that aren't too good can affect the adequacy of gasoline combustion, resulting in more carbon deposits than other vehicles.

For example, if the vehicle idles for a long time or the vehicle starts and stops due to road congestion. Although this situation is not caused by our subjective will, the engine always works at low speed, and if the gasoline is not burned sufficiently, it is easy to produce carbon deposits.

The generation of carbon deposition is mainly due to the insufficient combustion of fuel in the engine, or the paraffin gum substance that cannot be completely burned in the gasoline, which remains in the fuel injector, throttle, oil pipeline, spark plug and other components, and forms carbon deposition under the action of high temperature.

Disassembling and cleaning the engine is the most effective way to remove carbon deposits. In terms of results, the disassembly and cleaning of the engine is undoubtedly the best, but the whole process requires a lot of time and effort. In addition to engine disassembly and cleaning, car carbon deposits can also be cleaned in the following ways:

Hang the bottle above the engine, then pour dish soap into the bottle and guide it through the catheter to the engine to clean the carbon deposit. **About 1000 yuan. If the engine has significant carbon deposits, the three-way catalytic system can clog or be damaged.

The cleaning agent is injected into the machine, and then the machine is pressed to touch the combustion chamber to dissolve the cleaning agent in reaction with the carbon deposit, and then the waste liquid is pumped out. This method has a good effect on some serious carbon deposits, and there is no need to dismantle the engine, but the cost is high, and the oil needs to be changed after cleaning.
