What is car sludge? What is the difference between carbon deposits?

There are two types of oil sludge, one is low-temperature oil sludge and the other is high-temperature oil sludge.

1.Low temperature sludge:Low-temperature sludge is produced by the interaction of fuel and water into the crankcase during short runs and low temperatures, without completely evaporating, and then mixing with the oil.

2.High Temperature Oil Sludge:High-temperature sludge is caused by impurities mixed into the engine oil or the engine oil itself, in a high-temperature environment.

Medium oxidation, and the formation of sticky or colloidal substances that clump together with each other.

Hazards of oil sludge and carbon deposits.

Similar, even more serious than carbon deposits. It is mainly attached to the metal surface of the internal parts of the engine, which affects its heat dissipation, which in turn leads to high oil temperature and deterioration of engine performance.

Oil sludge mixed in the engine oil will affect the fluidity of the engine oil, resulting in insufficient lubrication of the engine and damage to the engine. It is even possible that the oil sludge will adhere to the inner wall of the oil pipe, and in serious cases, it will be completely blocked, resulting in dry grinding of the engine without any lubrication of the oil, which has a very serious impact on the engine, far exceeding the impact of carbon deposition on the engine.

Car sludge is a mixture of engine oil and dust, and it's nice to help you, hopefully.

Oil sludge is a mixture of debris and oil impurities rubbed down by parts, and carbon deposition is a hard substance adsorbed on spark plug valves and pistons due to the accumulation of gum and other impurities in gasoline and engine oil caused by insufficient combustion at high temperature.

It will affect the power, performance and noise of the car.

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.

Causes of oil sludge.

The sludge produced in different parts of the engine can be divided into low-temperature sludge and high-temperature sludge. Low-temperature sludge is produced by the combined action of blow-by gas (containing unburned fuel and water) and engine oil. At low temperatures or short runs, the moisture and fuel in the crankcase do not evaporate completely, resulting in emulsification, which leads to sludge formation.

High-temperature oil sludge is in the case of high temperature, polymerization into some relatively large Zheng Beizi, resulting in the thickening of the oil in the machine cluster, that is, the viscosity of the oil has changed, and over time the accumulation of oil sludge has been formed, which can lead to the increase of oil viscosity, blocking the oil circuit and causing insufficient oil supply. The oil sludge that has been formed for a period of time will become hard and brittle after being heated at high temperature for a long time, which is the so-called "black oil sludge". Black sludge can lead to increased wear and tear on components and even seizures.

PS: Deferred maintenance may exacerbate sludge formation).

Hazards of oil sludge.

Oil sludge is more harmful than carbon deposits:

1.Sludge adhesion to the inner wall of the crankcase will reduce the heat dissipation capacity of the cylinder block, resulting in high oil temperatures and reduced engine power.

2.Sludge adheres to the internal oil duct of the engine, which will increase the flow resistance of the oil, reduce the flow of oil, and affect the lubrication effect between components.

3.A large amount of oil sludge may block the oil passage, resulting in no lubrication between the components to form "dry grinding", which in serious cases will lead to the phenomenon of burning tiles and holding shafts.

A certain amount of sludge and carbon deposits will accumulate in the lubrication system of diesel engines. Sludge is produced due to the decomposition of additives added to the oil, which can occur if the additives added to the oil exceed the recommended service life or if the oil is replaced for too long. Carbon deposition is caused by the deposition of residues generated during the combustion process of the engine on the surface of the engine's internal parts, such as intake manifolds and piston rings, resulting in the formation of carbon deposits, which will affect the performance and fuel efficiency of the vehicle.

However, it should be noted that compared with gasoline engines, diesel engines usually have more serious carbon deposition problems because of their different combustion methods and combustion temperatures. Therefore, for diesel engines, it is very important to change the oil and filter regularly and carry out normal maintenance. Keeping your engine clean and using high-quality fuels and lubricants can help reduce sludge and carbon deposits and extend the life of your engine.

Most of the causes of oil sludge are caused by the lack of daily maintenance of the car, but many friends do not know what the reason is, so how is the car oil sludge generated? Let's find out!

1. Cars often use cars for short distances: short-distance use of cars is the main reason for the production of low-temperature sludge, which is different from the sludge produced by high temperatures, which is caused by the start of the car before it is preheated in place.

2. Low oil quality: the role of the oil itself is to lubricate and clean the various parts of the car, if the oil that does not meet the quality is used, it will not achieve the effect, so that the possibility of sludge increases, if it is a fake oil, it will even lead to serious consequences of engine cylinder bursting.

3. Car maintenance is not in place: the state dust fierce car maintenance is a periodic, if the car maintenance bridge has been continuing the maintenance cycle, there is no timely replacement of oil and other operations or the car cooling system and other key parts are not maintained in place, which are the reasons for the appearance of sludge.

The biggest reason for the production of automobile sludge is caused by insufficient maintenance, so as long as regular maintenance is done in daily maintenance and the maintenance of various parts of the car is in place, the generation of oil sludge can be effectively prevented.

When using internal combustion engine oil in an engine, oxidation is inevitable due to high temperatures, the presence of air, and the catalytic action of metals, resulting in the formation of paint film and carbon deposits. The formation of paint film and carbon deposit is also related to the fuel used in the engine, and the fuel is further oxidized and condensed with the internal combustion oil to form paint film and carbon deposit after the carbon generated by incomplete combustion and partially oxidized fuel enter the crankcase.

If the paint film and carbon deposits are deposited in the piston, the piston ring will stick to death in serious cases, and the ring can not be sealed well, and the oil channeling phenomenon is more serious. If the paint film and carbon deposits are deposited on the friction surface, the friction loss will increase and the effective power of the engine will be reduced. After the paint film and carbon deposit enter the oil tank, it forms "oil sludge" together with water and other impurities, and the oil will block the filter screen when it passes through the oil filter, affecting the normal oil supply and shortening the oil change period.

In addition to the operating conditions of the engine and the nature of the fuel used, the formation of paint film and carbon deposits is highly dependent on the quality grade of the oil selected. The oxidation performance and cleaning performance of medium and high-grade internal combustion engine oil are much better than that of ordinary engine oil, and it has a strong inhibition ability to the formation of paint film, carbon deposit and oil sludge, which can reduce the formation of the above deposits in the process of use of engine oil and ensure the normal operation of the engine.
