The most effective way to remove oil sludge from a car engine?

The removal method of automobile engine sludge is: 1. Release the oil pan oil when the engine is heated, and install the plug back after the oil is exhausted; 2. Add the same amount of light diesel oil as the engine oil to the crankcase, and start the engine to run idling 5 minutes after the engine is turned off; 3. Release the oil in the oil pan and add new oil, and after driving 20 kilometers, change the oil again. The principle of the engine is:

1. Mix air and gasoline into a mixture in a certain proportion; 2. The suction stroke will be sucked into the cylinder, and the mixture will be compressed and ignited to produce heat energy; 3. The high-temperature and high-pressure gas acts on the top of the piston, pushes the piston to reciprocate linear motion, and outputs the machinery through the connecting rod crankshaft flywheel mechanism. The maintenance methods of the engine are: 1. Use qualified engine oil; 2. Use qualified coolant; 3. Clean the scale of the water tank regularly; 4. Regularly remove carbon deposits from the engine; 5. Replace the air filter, oil filter and gasoline filter of the vehicle on time; 6. Check the use of spark plugs; 7. Maintain normal speed.

1.As soon as you notice that sludge has formed, it is time to change the oil and oil filter immediately. It can be cleaned with an inside engine cleaner before changing the oil.

2.Engine oil oxidizes under the catalytic action of combustion at high temperature, air, fuel and metal, and naturally forms paint film and carbon deposits, which are the initiators of oil sludge, which can not be avoided, and the oil has a detergent and dispersant to remove carbon deposits, which can remove dirt and metal surfaces, and automatically keep the inside of the engine clean, and these dirt will be discharged with the old engine oil when changing the oil, so the discharged oil is black.

1. You can use engine cleaner to add oil to the engine oil filling port, and then ignite for about 5 minutes, and then release the engine oil.

2. If it is particularly dirty, release the oil first, then add diesel, unplug the high-voltage line, and use the starter to hook the body for about 2 minutes, not too long. Otherwise, the oil seal of the body is easy to be damaged.

The sludge is too thick mainly by you not often.

If it is caused by maintenance, it is recommended to do maintenance frequently, develop good maintenance habits, and add good quality oil. If the sludge is not too thick, there is a 4S shop where you do maintenance with engine cleaner! If it's thick, don't use that, lest the plug have holes!

In a word, do more maintenance! Wait for an overhaul when your car's engine power is not good, and then everything will be solved.

Add 97 oil, or ethanol gasoline. Find a section of high speed, 130 (120* not speeding). Run for one to two hours.

Carburetor or tarmac cleaner can be used.

1. Use cleaning agent.

Pour the engine cleaner into the oil tank, idle for 5-10 minutes (if the engine has not been cleaned for a long time, the cleaning time can be appropriately extended), empty the old engine oil with cleaning agent in the engine, replace the oil filter, and add new oil.

2. Disassemble the engine for cleaning.

If there is too much sludge inside the engine, it is best not to wash, because the sludge inside the engine is particularly much, if the sludge inside the engine is cleaned at this time, it is possible to make a large piece of sludge fall off, these shedding sludge may block the oil passage of the engine, and it is also possible to block the oil pump, the consequences are more serious, so the engine can only be disassembled for cleaning.

How to remove engine grease and sludge:

1.Mechanical removal.

The use of steel brushes, sandpaper or nylon rollers containing abrasives to remove the metal on the surface of the parts is widely used.

2.Solvent wipe.

Wipe with absorbent material dipped in solvent, commonly used solvents are petroleum and chlorinated solvents. Many solvents are flammable and prone to disasters, so non-flammable solvents should be used. In addition, the type of metal material to be removed should be specified to keep the cleaned parts from corrosion.

3.Emulsion clearing.

Emulsion removal is the use of organic solvents in suspended water. It effectively removes grease and other dirt and leaves a thin anti-rust film on the metal surface. Since this removal method uses solvents, there is a risk of fire, and the disposal of waste solvents should be done with care.

4.Semi-water clearing.

There are two main ways of semi-water removal: one is the above-mentioned emulsion removal; The other is to wipe with a solvent first and then rinse in water. Commonly used solvents are terpenes, esters, and hydrocarbons.

5.Caustic washing. Alkali metal salts (caustic, silicate and carbonate) are mixed with the surface activator that is prepared according to the appropriate ratio, is very effective for the removal of metal dirt, sprays on the dirty parts after dissolving in hot water, can generally remove most of the dirt on the metal surface, its cost is the lowest, and it is a suitable method for batch automatic removal.

6.Pickling. Inorganic acids are usually used, but organic acids can also be used. By adding wetting agent to the acid aqueous solution, the purpose of rust removal and descaling can be achieved.

The cleaning function is done by the engine oil. Engine oil carries dirt away from friction surfaces and into the oil pan, where it is trapped as it passes through the oil filter, while the clean oil continues to scrub. In this way, the reciprocating cycle can keep the machine base clean and normal operation.

It can be seen that the stronger the oil circulation and flow ability, the faster the cleaning effect can be improved. If the viscosity of the oil is large and the circulation speed of the oil is slow, the number of times it passes through the filter will be reduced, and the impurities such as metal grinding debris, carbon particles, and dust that are worn down cannot be taken away from the friction surface in time, and its cleaning effect is poor.

It is recommended to change the oil and filter regularly according to the service interval (**), or to clean the engine before changing the oil to clean the sludge more thoroughly.

There are three ways to remove engine sludge:

1.Clean with light diesel oil: after the engine is heated, release the oil in the oil pan, install the plug, add the same amount of light diesel oil to the crankcase, start the engine to idle for 5 minutes after the engine is turned off, release the oil in the oil pan, add new oil, and change the oil again after 20 kilometers.

2.Use detergent: Pour detergent into the engine's fuel tank, idle and check 10 minutes after starting. If it hasn't already, extend the cleaning time, drain all the old oil, replace the filters, and pour new oil.

3.Disassemble the engine for cleaning: If too much sludge is generated inside the engine and cannot be cleaned with detergent, it may cause large pieces of sludge to fall into the oil circuit of the engine, clogging the oil pipe, causing serious consequences. The engine needs to be disassembled for cleaning, and it needs to be disassembled by professionals.

The engine sludge is clear that you can go directly to the 4S shop, which is more convenient. It's okay to want to clean up engine sludge yourself, and there are some ways to learn from it.

1. Clean with cleaning agent. This is mainly the engine cleaning agent, pour it into the oil tank, idle for 5 to 10 minutes, pour in the old engine oil with the cleaning agent, and drain it. After that, you need to change the oil filter and add new oil.

2. When the engine is hot, the oil pan oil can be discharged, and after the oil is exhausted, the plug can be installed back.

Sometimes there is too much sludge inside the engine, which is not suitable for cleaning by the above method, which may require the engine to be disassembled and cleaned, but this method is generally not suitable for the owner to remove by himself. Of course, it is also very convenient to go to the 4S store for cleaning.

The engine is prone to sludge, once the engine sludge appears a lot, this is still very harmful to the car, the regular operation of the car air intake system will be endangered, and it will also cause the blockage of the main oil channel.
