Is there carbon deposit in the engine during maintenance?

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.

Hello. Cleaning carbon deposits is necessary to improve fuel economy.

Sometimes the engine burns incompletely, and it is normal to have carbon deposits! Generally, about 60,000 kilometers to clean up carbon deposits! The main thing is inlet cleaning!

How long has the car been around, dear? Generally within 3 years, the oil specifications are a little higher, there is no need to clean, excessive maintenance will also affect the service life of the engine, 8 years of experience in repairing cars, I hope to help you.

It is necessary for the engine to clean the carbon deposits.

If there is a large amount of carbon deposition in the engine, it will cause the intake and exhaust valves to be closed and not sealed, the friction in the cylinder will become larger, and the heat dissipation capacity will become weaker, which will affect the use of the experience, and the carbon deposition will form a large layer, and it will face the danger of pulling the cylinder, so it is useful to clean the engine carbon deposition regularly to ensure the normal driving of the vehicle.

Excessive carbon deposition causes incomplete combustion of gasoline, resulting in increased fuel consumption of the vehicle, engine shaking, idle shaking, exhaust emissions exceeding the standard, etc., cleaning carbon deposits can ensure the normal operation of the engine, and it will not be excessive exhaust emissions.

Cleaning method of carbon deposits

At present, there are two main types of effective cleaning of carbon deposits: dismantling cleaning method and dismantling cleaning method.

1. Dismantle-free cleaning method.

This method is to use special cleaning equipment with the corresponding cleaning agent to thoroughly clean the entire fuel system, it can be added to the cleaning product in the equipment by combustion without disassembling the original parts, and the carbon deposits of the fuel injector, valve, piston top and combustion chamber are cleaned layer by layer, and the cleaned carbon deposits will not fall into the cylinder in a lump and aggravate the wear of the cylinder, but are discharged through the exhaust gas in the form of fine particles.

However, the cleaning method of the equipment added by combustion alone cannot clean the hard carbon deposits that have been formed for a long time, and it can only clean the newly formed carbon deposits in the fuel injector, combustion chamber, piston top and other parts.

2. Dismantling and cleaning method.

Cleaning the valve is relatively simple, and the intake manifold is removed and can be removed by soaking it in a detergent or wiping it by hand. When cleaning the carbon deposits of the injector, the injector needs to be removed, and it can be cleaned by soaking or ultrasonic. Engine cylinder carbon deposits need to be dismantled timing belts, cylinder heads and other parts before they can be cleaned.

Hello, under normal circumstances, generally when the mileage of the car reaches about 30,000 kilometers, it is necessary to clean up the carbon deposit, it is not necessary to clean it frequently, and there is no need to clean it up when there is nothing wrong with our car. Auto repair shops often tell car owners that car owners need to clean up carbon deposits, sometimes it may be to make money, and they don't consider whether they need to clean up during this time period.

When the car engine detonation, it means that our combustion chamber carbon deposits; When the engine shakes and the car accelerates unsmoothly, it may be carbon deposits on the fuel injector; When the car has a poor sense of acceleration, shakes when idling, or has difficulty starting, the fuel consumption of the car increases many shifts because of carbon deposits on the throttle. The abnormal performance of these cars shows that our cars need to clean up the carbon deposits as soon as possible, and they have been piled up for comparison.

There are also some fuel treasures that can clean up carbon deposits, although they can achieve some cleaning effects, but some fuel treasures are a kind of harm to the car engine. There are still many car owners who have heard from individual bad clerks that high-grade gasoline will produce less carbon deposits, so they don't look at what kind of gasoline they should add to their cars, so that the carbon deposits generated by our engines will increase.

Engine carbon cleaning is necessary.

Carbon deposition is a kind of coke-like substance produced by unsaturated olefins and gum in the fuel at high temperature during the working process of the engine. It needs to be cleaned regularly, and the main parts of cleaning are: cleaning the carbon deposits on the throttle valve, cleaning the carbon deposits inside the engine, cleaning the carbon deposits in the oil circuit, and cleaning the carbon deposits in the air intake system.

In this way, the better operation of the vehicle can be guaranteed.

Cleaning recommendations

1. Throttle carbon deposition cleaning.

The throttle is the throat of the engine, and it depends on whether the breathing is smooth or not, and the cleaning cycle of the throttle is about 20,000 kilometers under normal circumstances. The throttle must be cleaned regularly, and if the engine shake is more serious, the throttle needs to be cleaned immediately.

2. Sludge cleaning inside the engine.

Generally done during maintenance, you need to use a professional cleaning agent or cleaning type of engine oil, after pumping off the old engine oil, pour the cleaning oil into the engine, cover the oil cap, turn off the ignition after idling for 10 minutes, and then replace it with new engine oil. The detergent dissolves deposits such as sludge, gum, moisture and metal debris inside the engine, and can reduce contamination of new oil and extend the life of the engine. Generally, the engine is cleaned once a year for 30,000 kilometers or once a year.

3. Carbon deposition cleaning of oil circuit.

The purpose of oil circuit carbon deposition cleaning is to solve the problem of insufficient horsepower, increased fuel consumption, abnormal jitter, poor acceleration and difficult start caused by carbon deposition and dirt in the oil circuit system.

4. Carbon deposition cleaning of the air intake system.

Carbon deposition cleaning of the air intake system mainly refers to cleaning the internal carbon deposits of the air intake tract and air intake pipe. The purpose of carbon deposition cleaning of the air intake system is to remove the carbon deposition inside the air intake system, increase the intake flow and speed, and reduce the phenomenon of engine shake and idle instability, and the general cycle is about 60,000 kilometers to do a cleaning.

Hello dear: there is a necessary amount for engine carbon deposition cleaning! It is necessary to remove carbon deposits from the engine.

Generally, the engine of a car needs to be cleaned once when it is about 30,000 kilometers away from the starting chain. According to current technology, the combustion of gasoline cannot reach complete combustion. Therefore, as long as the engine is rotating in the response to the penson, there will be carbon deposits in the mu, which is an inevitable problem.

That's all for me, I hope it helps! If there is a ** that does not satisfy you, please don't be angry! You can tell me the detailed problem again, and my brother will do his best to solve the problem for you!

Have a great day!

Summary. Dear, it is necessary to clean the carbon deposits of the engine. Carbon deposits can accumulate on fuel injectors, exhaust pipes, and valves, which can affect engine performance and emissions.

Long-term carbon build-up can exacerbate wear and tear on engine components, leading to abnormal engine performance or stalling problems. Therefore, it is necessary to carry out regular engine carbon cleaning to ensure the normal operation of the vehicle.

Pro, it is necessary to start the carbon deposition cleaning of the ship. Carbon deposits can accumulate on fuel injectors, exhaust pipes, and gas doors, which can affect engine performance and emissions. Long-term carbon deposition will exacerbate the wear and tear of engine components, resulting in abnormal engine performance or stalling problems.

Therefore, it is necessary to carry out regular engine carbon cleaning to ensure the normal operation of the vehicle.

Engine carbon deposition cleaning reduces engine wear: during the combustion process of the engine, the fuel will volatilize, and the remaining carbon deposits will accumulate in the fuel chamber, cylinder, piston and other parts of the engine; Carbon deposits look like a sticky mortar that clogs the thermal pores of the engine; As a result, the engine overheats and accelerates the wear of pistons and other components, so regular cleaning of the engine can reduce such wear. Engine carbon cleaning improves engine performance

Carbon deposits will increase engine wear and affect engine efficiency. Carbon deposition will also affect the reliability of the engine, it will not only change the internal airflow of the engine, but also reduce the power of the sock engine, reduce the combustion efficiency of fuel, increase engine noise, and increase toxic exhaust emissions; Therefore, engine cleaning can change the performance of the old and hungry engine. Engine carbon deposition cleaning protects the environment: improves the combustion efficiency of engine fuel and effectively reduces the emission of toxic exhaust gases from the engine.

In addition, engine cleaning can also reduce engine noise, reduce the wear and tear of engine casing and internal parts, thereby shortening the engine repair and maintenance interval, thereby reducing the environmental pollution of waste parts.

If the engine carbon deposition is not cleaned for a long time, it will lead to: reduce the engine power, the power output is uneven, and gradually decay; Excessive carbon deposition will increase fuel consumption and increase the burden of fuel costs; Difficulty in cold start, i.e., difficulty in catching fire, not easy to drive; Carbon deposits in the combustion chamber are severe, causing cylinder knockout, low-speed acceleration noise, and damage to the piston and crankshaft, which seriously affects the safety of the car.

Is it necessary to clean the carbon deposits of the engine?

If the engine carbon deposition is not cleaned for a long time, it will lead to: reduce the engine power, the power output is uneven, and gradually carry the attenuation; Excessive carbon deposition will implicitly increase fuel consumption and increase the burden of fuel costs. Difficulty in cold start, i.e., difficulty in catching fire, not easy to drive; Serious carbon deposition in the combustion chamber causes cylinder knocking, low-speed acceleration noise, and damage to the piston and crankshaft, which seriously affects the safety of the car.

Extended Information: Carbon deposits are mixtures that accumulate on the valves, combustion chambers and intake ducts of an engine. It is a rotten brigade rental caused by the failure of the engine's oil to fully combustion, under the catalytic action of high temperature and oxygen hunger, the formation of hydrochloric acid and resinous gum, adhesion to the surface of the part, and then through the action of high temperature to further concentrate into a complex mixture of asphaltene and oil char.

Carbon deposition can be divided into two types: valve, combustion chamber carbon deposition and intake pipe carbon deposition.

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 under the repeated high temperature action of the engine is called carbon accumulation.

One of the reasons for carbon accumulation 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:

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 don't clean up the carbon deposits 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.
