How often does it cost to clean the carbon deposits of the BYD G5 engine

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.

There is no fixed deadline for this, but generally speaking, it is more cost-effective to start with a new car and clean it once every 20,000 kilometers. The throttle machine carbon two million cleaned once'The engine combustion chamber engine carbon can be cleaned once about 50,000.

1. The most common is to disassemble the throttle, clean the front and back of the throttle with a carburetor, and dry it with a cotton cloth. Generally, it is recommended to clean the lower throttle for a year or 20,000 kilometers, of course, different models will have different cleaning cycles, we can do it according to the maintenance manual.

2. Carbon deposition cleaning inside the engine, we can do it before we want to change the oil to a new one. Open the oil cap, add detergent, mix with old oil, and idle for about 10 minutes. You can buy the detergent by yourself, the operation is very simple, and you can operate it yourself.

3. To clean the air intake system, buy a bottle of air intake system cleaner, 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.

It mainly has an impact on power and fuel consumption, and if the carbon deposit is more serious, it will also aggravate the wear of the parts.

The hazards of carbon deposits to the engine can be divided into two aspects: structural damage and performance degradation

1) Structural damage:

The various structures in the cylinder that make up the combustion chamber are the main parts where carbon deposition occurs, including the top of the piston, the spark plug, the injector in the cylinder, the intake and exhaust valves, and the cylinder inlet of the intake pipe.

2) Leads to a decrease in engine performance.

The main reasons for the power decline --- serious carbon deposition are: spark plug carbon deposition weakens the ignition ability or causes ignition failure, and the pressure drop caused by cylinder leakage (valve and piston), etc., which is more obvious at high load or low speed.

An increase in fuel consumption --- a decrease in power is accompanied by a certain increase in fuel consumption, as greater throttle opening and increased fuel supply are required to obtain the same power as before the effects of carbon deposits. Therefore, if there is an unexplained increase in fuel consumption, it is necessary to check for the presence of carbon deposits in the cylinder.

Emissions of pollutants from the exhaust gas increase--- and it is usually not noticed until the annual inspection of the car that the pollutant emissions in the exhaust gas are increased. At present, only carbon monoxide, hydrocarbons and nitrogen oxides are detected, and all three indicators can rise or exceed the standard when carbon is deposited, which may occur earlier than the decrease in power and the increase in fuel consumption.

Other changes--- there may also be difficulties in cold start, abnormal noise during acceleration, etc.; When the piston carbon deposit is severe, it may cause the piston ring to be stuck and scratch the cylinder wall, resulting in serious air leakage (cylinder pulling).

The impact of engine carbon deposition on the car is still 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, and it is not easy to get on the car.

Finally, serious carbon deposition in the combustion chamber will also cause cylinder detonation, and there will be a sound of low-speed acceleration, which will cause damage to the piston and crankshaft, thus seriously affecting the safety of the car. Then there is the excessive discharge, which not only fails the annual inspection and inspection, but also directly aggravates the harm of polluting the environment. The specific principle is that if you do not 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 they harden 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. Because the structure of carbon deposition is similar to that of a sponge, when the valve forms carbon deposition, a part of the fuel injected into the cylinder will be adsorbed, which makes the concentration of the mixture that really enters the cylinder thinner, resulting in poor engine work, and abnormal phenomena such as difficult starting, unstable idling, poor acceleration, urgent refueling and tempering, excessive exhaust gas, and increased fuel consumption. If it is serious, it will cause the valve to be closed loosely, so that there is no cylinder pressure in the cylinder and it will not work completely, and even adhere to the valve to prevent it from returning.

At this point, the valve and piston will interfere with the movement, which will eventually damage the engine.

In fact, any vehicle has carbon deposits, and a slight carbon deposit has no effect on the vehicle. Only if there is too much abnormal carbon deposit, it needs to be treated, but the method is not to deal with carbon deposits, but to find the reason for the abnormal increase in carbon deposits.

Look at whether your car often runs at high speed, if it is often high-speed, 30,000 is enough to clean it once, and if you don't often pull the high-speed, you need to clean it once. It's very simple, buy a small bottle of engine carbon scavenger, pour it into the fuel tank and you're good to go!

Hello! Forty or fifty thousand kilometers to clean once! [If you have a problem with the car, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Hello car owner, normal maintenance on time, cleaning every 60,000 kilometers can be [if you have a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Cleaning up carbon deposits is about 400 700 yuan, depending on the vehicle, different places, ** is also different. The most important step is to use detergent to hit the combustion chamber to extract the waste liquid and clean the carbon deposits after a chemical reaction.

The engine has been working for a long time and there is more or less carbon deposit, a certain degree of carbon deposit is allowed, and only excessive amount will affect the performance. When you find that the cold car needs to start normally many times, the acceleration is slow and the acceleration is weak, the exhaust is pungent and the fuel consumption has increased compared to the past, then the carbon deposit of the engine is already a bit serious and needs to be cleaned up.

I believe that even students who do not know about automobiles have heard of the term carbon deposit, yes, as one of the most common "chronic diseases" of the engine, carbon deposit exists in all parts of the engine. When we went to the 4S shop for maintenance, the after-sales receptionists must have recommended to us the engine carbon deposition cleaning project, so how is the engine carbon deposition cleaned? How much does it cost to clean up the carbon deposits in the engine?

Let's take you to find out.

How to clean up engine carbon deposits?

At present, for the cleaning of carbon deposits inside the engine, we can use three ways: additive cleaning, hanging bottle cleaning and disassembly cleaning, and the most mainstream is hanging bottle cleaning.

Additive cleaning (fuel treasure): additive cleaning is to directly fill the cleaning agent into the fuel tank and mix with the fuel, after the vehicle starts, the cleaning agent will enter the combustion chamber with the fuel, and the cleaning agent will enter the combustion chamber at the same time, the carbon deposits inside the engine will be cleaned to a certain extent.

Hanging bottle cleaning: Hanging bottle cleaning is what we usually call no-dismantling cleaning, which is also a cleaning method promoted by 4S stores. In this method, the cleaning agent is sucked into the engine combustion chamber in the form of a hanging bottle from the engine intake duct along with the intake air flow, and in this process, the cleaning agent cleans the carbon deposits in the engine intake duct and combustion chamber.

Disassembly and cleaning: As the name suggests, disassembly and cleaning is to disassemble and clean the parts of the engine that have carbon deposits. Although this method has the best cleaning effect, due to the heavy workload, time-consuming and labor-intensive, generally 4S stores will not provide dismantling and washing services.

How much does it cost to clean up carbon deposits in an engine?

Since the current 4S store is pushing the way of hanging bottle cleaning, and basically does not provide disassembly and cleaning services, we will introduce the **:

In general, depending on the premium of the vehicle brand and the different cleaning materials used, it takes about 300-600 to clean the carbon deposit of the engine once.

Ask a lot of questions, how often do you usually clean it?

How often should I clean it?

Is it necessary to change the engine oil to clean the carbon deposits in the engine?

Is it necessary to change the engine oil to clean the carbon deposits in the engine?

Hello answer. Long-term low-speed driving, urban road conditions, will lead to the rapid generation of carbon deposits, my car is recommended to clean the throttle every time it is maintained, add a bottle of fuel cleaning agent. That's 5,000 km or 6 months.

When you are maintaining your car, change the engine oil and add a bottle of car engine cleaner.

By the way, if your car often runs at high speed, if it is often at high speed, 30,000 is enough to clean it once, and if you don't often pull high speed, you need to clean it once.

200-1000. If the engine cleans up the entire oil circuit system, it includes different items such as the combustion chamber, fuel injector, air intake system, three-way catalysis, etc. Optional.

How much does it cost to clean up carbon deposits in an engine?

If the car department is poor, it will probably cost more than 300 yuan.

The engine to the 4S shop to do carbon deposition cleaning is hundreds, depending on the brand and model is different, you can also use gasoline additives, that is, fuel injector cleaning agent, when refueling, it will slowly clean the fuel injector carbon deposit. Note to choose reliable quality additives, otherwise it will affect the engine oil seal, I generally use the United States Ruianber, every time you add fuel in a ratio of 1000:1.

Generally speaking, the car travels more than 30,000 or 40,000 kilometers, and there are problems such as insufficient power and fuel consumption, which is likely to be caused by excessive carbon deposition in the engine.

About 300 yuan, including fuel injector, throttle and engine cleaning. Like more carbon deposits, bad power in the maintenance of the use of better oil can be improved, I will maintain the use of semi-synthetic oil carbon sludge is particularly much, the condition of the car is not very good, and finally in order to improve the condition of the car to upgrade the oil to German magic red oil, does not produce carbon deposits and can effectively remove sludge, now both in power and engine silent performance is very good.

When the car is driven for a period of time, you can go to the 4S shop to clean up carbon deposits, the specific price of each place is different, about 1000 yuan, the specific introduction is as follows:

Carbon deposition is a sticky gum formed by insufficient combustion of engine fuel and engine oil. This carbon deposit is not only present in the combustion chamber, but also at the cylinder edges, spark plugs, piston tops, and so on. Generally, it is not as good as cleaning up carbon deposits outside as well as cleaning up 4S stores.

Carbon deposits are still relatively soft and sticky when they first begin to form, like yogurt, but as they accumulate more and more, coupled with high temperature combustion, they will slowly become like jelly, become hard, and finally become a large piece of black carbon deposits. Don't wait until it's hard to go to a 4S store, you should go early.

The cleaning agent is injected into a machine, and then the machine pressurizes the combustion chamber to let the cleaning agent react with the carbon deposit to dissolve, 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 disassemble the engine, but the cost is higher, and the oil needs to be changed after cleaning.

Notes:

1. Carbon deposits are present in every car, but they are just somewhat different, but as long as they are cleaned regularly.

2. Pay attention to planning the route when driving, avoid congestion and routes with many traffic lights, and sometimes even take some ring roads, elevated, or even high-speed, even if the distance is farther, it is more fuel-efficient than congestion and traffic light sections, and it is not easy to produce carbon deposits.
