What is the most effective way to clean up carbon deposits? Teach you a trick

<> fact, carbon deposits do not appear all at once, but continue to accumulate in long-term car life, so by cultivating a good habit of using cars, it is helpful to alleviate the accumulation of carbon deposits. Generally speaking, as long as you add qualified fuel, change the engine oil regularly, air filter, avoid long-term low-speed driving, and even occasionally use some fuel additives, you can effectively alleviate the accumulation of carbon deposits.

But for models that have already generated carbon deposits, how to clean up the carbon deposits is the most effective? The easiest way is to clean the engine, but if this project is carried out in a 4S shop, it will generally be more expensive, so it is recommended that you go outside to find a trustworthy repair shop, which can be cheaper by more than half. Of course, for car owners with strong hands-on ability, they can choose to clean or even replace the parts that produce carbon deposits by themselves.

For example, the spark plug carbon deposit needs to be replaced, which is actually a relatively simple operation, as long as you buy a set of corresponding tools, you can operate it yourself.

The most effective way to clean carbon deposits in a car is not only to increase power, but also to reduce fuel consumption.

How to clean up carbon deposits in automobiles? Don't go to the garage anymore, teach you two tricks to accumulate carbon and run out by yourself!

Carbon deposits can cause insufficient combustion of gasoline and cause the engine to shake. The impact of engine carbon deposition on the car is quite large, first of all, to reduce the engine power, that is, to make the power output uneven and gradually decay, in other words, more and more powerless. The second is to increase fuel consumption and increase your financial burden.

The third is the difficulty of cold start, that is, the difficulty of ignition, it is not easy to get on the car, and finally the carbon deposit in the combustion chamber is strict, and a heavy one will also cause cylinder detonation, and there will be a sound of low-speed acceleration, which will cause damage to the piston and crankshaft, and cause high temperature of the engine, which will seriously affect the safety of the car. Then the emission exceeds the standard, not only can not pass the annual inspection, but also directly aggravate the harm of environmental pollution, solution: replace the good fuel, regularly add fuel additives, such as Marty, Tiger, Dodge, etc. to promote the combustion effect of fuel.

If you have no experience and equipment, it is not recommended to clean it up by yourself, and you can learn about the cleaning steps.

Generally, four parts should be cleaned: cleaning the throttle, cleaning the carbon deposits inside the engine, cleaning the carbon deposits in the oil circuit and cleaning the carbon deposits in the intake system.

Specific steps: 1. Clean the throttle: remove the engine trim cover, remove the throttle, and use carburetor cleaner to clean it, wipe it dry with a cotton cloth and install it.

2. Clean the inside of the engine: The cleaning method for carbon deposits inside the engine is also very simple, you only need to add a bottle of engine cleaning agent to the oil port before maintenance, and idle for about 10 minutes, and then immediately maintain and replace the oil filter.

3. Cleaning oil circuit carbon deposits: Cleaning oil circuit carbon deposits includes cleaning fuel injectors, combustion chambers, spark plugs, throttle valves and other parts. The purpose is to solve the intractable diseases such as insufficient horsepower, fuel consumption, wheezing and poor acceleration or difficulty in starting caused by carbon, gum and dirt in the oil circuit system.

Cleaning these does not require any disassembly, as long as the car tank is regularly added with special cleaning fuel additives can achieve a good cleaning effect.

4. Clean the carbon deposit of the air intake system: buy a bottle of air intake system detergent, pour it into the liquid storage tank of the special cleaning equipment, connect it to the air intake system, and use the vacuum to suck the detergent into the air intake road to achieve the purpose of cleaning. Cleaning the carbon deposits in the intake system mainly refers to cleaning the carbon deposits inside the intake tract and intake manifold.

The purpose is to remove carbon deposits from the intake system, increase intake flow and speed, and reduce engine shake and idle instability.

Carbon deposition is a kind of coke substance produced by unsaturated olefins and gum in the fuel at high temperature during the working process of the engine. It can accumulate in various parts of the engine, such as the intake and exhaust systems; fuel chamber; Fuel injectors, etc. It has the characteristics of oil absorption, which will make the incomplete combustion of gasoline become carbon deposits, layer by layer, thicker and thicker, so that a vicious circle.

The impact of carbon deposition on the vehicle is very large, it can reduce the engine power, increase fuel consumption, and in serious cases, it can also cause engine knocking, acceleration noise, damage to the piston and crankshaft, and even eventually lead to the engine burning oil needs to be overhauled. Carbon deposition is not only harmful to the car, but also great to the environment, which can directly affect the exhaust emissions of the car, resulting in the inability to pass the annual inspection.

The formation of carbon deposition is not a day or two, it requires a long process, just like the kettle at home, when the water alkali is not much, you can often use vinegar to boil, but if you do not treat it for a long time, when the water alkali has reached a very thick level, you can only use hard things to pick. The same is true for cars, regular cleaning with cleaning agents reduces the deposition of carbon deposits, if you feel that you don't need to do it, or you feel that you want to save money, it will eventually lead to the formation of too much carbon deposits, which is difficult to remove.

The reason for carbon deposition: determined by the control characteristics of the electric injection engine, the cylinder is first injected and then ignited every time it works, and the ignition is cut off immediately when we extinguish the engine, but the gasoline sprayed out by this work cycle can not be **, after the unburned gasoline in the cylinder volatilizes, the remaining glue and wax will be deposited on the cylinder wall and valve, which can only be attached to the intake valve and the combustion chamber wall. The method of removing carbon deposits, one is that the carbon deposits are not too serious, and the non-dismantling cleaning method is adopted, "The method is simple and labor-saving, and it only needs to be used in the correct way."

However, for engines with serious carbon deposits, this method is inadequate and cannot achieve the purpose of complete cleaning. After the disassembly and cleaning, if the engine performance is still bad, then you should pay attention to it, it may be caused by too much carbon deposits in the valve and cylinder, then you have to use the method of disassembling the engine to solve it. Valve carbon deposits can be easily cleaned by removing the intake manifold and soaking it by hand or with cleaning chemicals.

As for the cleaning of carbon deposits in the engine cylinder, it is necessary to "make a big move" and remove the cylinder head and timing belt before cleaning. However, you should still pay attention to the cleaning process. Car carbon deposition cleaning is a very important work, it is generally not recommended to operate by yourself, do a good job of going to the relevant professional place for cleaning, cleaning links are very important, in fact, daily maintenance is also very critical, to minimize the formation of carbon deposition can effectively protect the engine, you not only have to cultivate good driving habits, try not to shift gears at low speed, in this case gasoline combustion will occur inadequate, easy to produce carbon deposits.

Regular cleaning and maintenance is also important.

At high speeds, the vehicle can take advantage of fluid washout and high fuel efficiency to reduce carbon deposits in the engine. 2. Use fuel treasure: Fuel treasure is added to gasoline, and as the gasoline enters the engine block together, fuel treasure can soften the carbon deposit, and then it can be removed.

However, it requires a lot of fuel treasure, and the effect is not good.

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. Flushing with high-grade gasoline:

Because the addition of high-grade gasoline is relatively low, the standard gasoline has a high octane number, and the combustion is complete and clean, and the possibility of carbon deposition is relatively low. Residual carbon deposits can be effectively washed out by high-grade gasoline.

2. Use fuel to clean and clean additives

The cleaner is sucked into the fuel supply line along with the fuel when the engine is working. With the flow of fuel, it can not only clean off the gum and carbon deposits in the fuel tank, the gasoline pump filter and the fuel injector, but also automatically clean the carbon deposits on the valve and the engine cylinder when the engine is working normally, so that the engine can "rejuvenate" and regain its surging power.

Fuel additives:

In order to ensure the cleanliness of gasoline, some car owners will add gasoline cleaners to gasoline. This can effectively prevent the formation of carbon deposits on the metal surface, and with the flow of fuel, it can not only clean off the gum and carbon deposits on the fuel tank and the fuel injector on the fuel tank, gasoline pump filter, but also automatically clean off the carbon deposits on the valve and the engine cylinder when the engine is working normally.

Carburetor Cleaner:

The operation method is relatively simple, remove the engine trim cover, remove the throttle valve, and use a carburetor cleaner to clean it, wipe it dry and install it. However, this method is generally only effective for cleaning the valve carbon deposits.

3. Remove the spark plug and pour carbon deposition cleaning agent into the combustion chamber from the throttle valve, generally with head water, a treasure is sold, and 5 to 6 liters of a car is enough. Pour directly from the throttle valve, soak for half an hour after filling, and then pump out the liquid.

Then support the front wheel, hang the 1st gear to turn the tire, let the piston move up and down, the liquid that cannot be pumped will be sucked into the cylinder, just in time for the combustion chamber to be washed with carbon deposits.

Finally, when you pull out the liquid from the spark plug again, you will find that the liquid is black and full of dissolved carbon.

If you want to do it, you can fill it with gasoline again, rinse it again and again, it will be cleaner, and finally drain the liquid, start the motor and let the remaining liquid spray out of the spark plug. Change the oil, install the spark plugs, and put the throttle on the throttle when the water temperature is normal.

Oh, yes. There are various ways and methods, different situations, and different choices, so we need to fully combine our own specific situation and choose the method that is really suitable for us. I hope it can be of some help to you and solve your problems.

1. When carbon deposits adhere to the intake and exhaust valves, the intake and exhaust valves are not closed tightly and the air leaks, and the pressure in the engine cylinder drops, which directly results in the difficulty of engine activation and shaking under idle conditions; At the same time, it affects the section of the mixture into the combustion chamber, and the carbon deposition can adsorb a certain amount of the mixture, thereby reducing the engine power.

2. When the carbon deposit adheres to the cylinder and piston top, it will reduce the volume (space) of the combustion chamber and increase the cylinder compression ratio, and when the compression ratio is too high, it will cause the engine to burn prematurely (engine knocking) and reduce the power generation.

3. When the carbon deposits adhere to the spark plug, it affects the quality of the spark; Not even a jumper.

4. When carbon deposits are formed between the piston rings, it will easily jam the piston rings, causing oil burning and straining the cylinder wall.

5. When carbon deposits adhere to the oxygen sensor, the oxygen sensor cannot correctly perceive the exhaust gas condition and cannot correctly adjust the air-fuel ratio, so that the engine exhaust gas exceeds the standard.

6. When carbon deposition is formed inside the intake manifold, it becomes rough inside, which affects the formation and concentration of combustible mixture. Carbon deposits are so harmful that they must be removed immediately.

If the carbon deposit is not cleaned for a long time, the operation of the whole vehicle will be caused, and the internal channel of the engine will be blocked by carbon deposits, so that the engine power will deteriorate, thereby reducing the power of the automobile engine, increasing fuel consumption, and the combustion rate will 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.
