Effective engine flushing. Engine cleaning methods that actually work

How to keep the engine lubrication system clean for many years. After all, this factor is one of the most important for the health of the engine when operating a car. Why is this needed, let's figure it out. Sludge, slag, carbon - all this is the result of the combustion process in the engine. When we buy a car, due to lack of time, money, etc., we simply forget about proper car maintenance. And it drags on for a long time, during which sediment in the form of combustion products settles on engine parts. Due to this, their friction increases - metal on metal, and destruction occurs accordingly.

The oil filter does not always cope with its task and microparticles that do not fall under the filter begin to circulate in the engine, causing microscopic scratches and damage to the cylinder walls and bearings. Valves begin to stick, hydraulic compensators knock, the operation of the pistons is disrupted, causing engine vibrations. Then the car owner wonders why the engine consumes liters of oil per 1000 km. where is this from? high consumption fuel. Here is the result of the car owner's inaction, see the picture below. This motor has not even completed 30,000 km. Look at the condition it's in.

Why flush the engine?

What should I do, you ask?! You don’t have to do anything, you just have to wash it, that’s all.
Many people are skeptical about engine flushing, for good reason. A lot of junk has appeared on the market, supposedly washing products that contain an ultra-high solvent and are in no way suitable for the engine. Don't pay attention to cheap washes.

DO NOT grab the first one you see off the store shelf.
A good flush is a product that will restore compression in the engine cylinders, effectively remove sludge and dirt, and not only allow it to fall off, but also dissolve it, so that it does not clog the channels and is easily removed from the mixture system.
Also, a good flush should cover all microscopic defects in the engine, and restore both the oil seals and all rubber seals.

Pros and cons of engine flushes.

Poor flushing:
- Corrosion of the oil seal as a result of engine leakage
- Loss of compression
- Increased oil consumption
- loss of power
- clogged channels in the engine

Pros of a good flush:
- Restored engine compression (You can do a test before and after use)
- reduction of fuel and oil consumption
- Sludge removal
- The car becomes more accommodating and lighter
- Engine noise is reduced
- Has TUV RUF ROHS approval

Methods for cleaning a car engine

Let's look at several ways to effectively clean the engine of carbon deposits and sludge.

1. In spare parts stores you can find a product such as, for example, motor oil with a viscosity of SAE 40. This is a seasonal summer product that has a fairly high cleaning power and effectively cleans the engine.

Drain the used engine oil and refill with this oil without changing the oil filter. Start the engine and idle for about 15-30 minutes, you can take it for a ride a little.
Then drain the oil, most likely it will be black, as it will collect all the dirt that has collected on the walls, parts, etc. Repeat everything done previously until the color of the oil is the same as you poured it.

This is one of the best ways flush the engine, and after the clean oil is drained, you will be sure that the engine is clean.
Result. After this method of flushing the engine of a problematic 1992 Ford Explorer, oil and fuel consumption decreased, the engine began to run quieter, the car became smoother and more responsive.

2. The second way is to wash the engine well.
Flushing from Liqui Moly Engine flush is popular among the common people and has long deserved recognition. It is poured into the engine with used oil, the engine warms up for about 10 minutes and then drained. Excellent product, easy to use, and most importantly effective.

Always take it as a consumable when replacing motor oil. Long-term flushing is also suitable here if everything is really bad.

Fill it up 300 km away. before the shift, the cleaning will already begin.

Lambda Oil Primer.

Here is another interesting and super effective thing for flushing a car engine - Lambda Oil Primer.

This product is approved by TUV, ROHS and VAG. Works well in restoring engine compression. Many who used it were simply eager to do a compression test before and after use. The results were great after washing. Ideal cleanliness and operation of the motor, as well as its subsequent protection.
Used in gasoline and diesel engines. One of the best premium washes in the world.

As for the product characteristics:
Effectively cleans the oil lubrication system, preventing problems associated with the accumulation of sludge, dirt, and deposits. After cleaning, clean oil in a clean engine is guaranteed for many kilometers.
It is used both in the engine and in gearboxes and differentials. Contains a lubricant that protects mechanical parts during the cleaning process.
Suitable for all types of modern and old gasoline engines. and design engines. added to any motor oil.

fuel and oil consumption increases
on idle speed extraneous noise and vibration appear
dynamics worsen.
engine stability decreases
CO-CH emissions are increasing.

Incomplete combustion of fuel, driving low revs, spark plug failures lead to the formation of carbon deposits on the cylinder walls, injector tips, spark plugs and deterioration of engine performance as a whole. Regular cleaning of your car engine helps increase its life.

H2 removes carbon deposits with hydrogen, which is supplied to the gas-air mixture. The proton-membrane electrolysis unit used is patented in the Russian Federation and approved for use.

The effect is felt immediately:

the engine runs smoother and quieter
fuel consumption decreases
the car becomes more responsive and dynamic
engine service life increases.

It is safe. In addition, engine support in good condition eliminates the cost of repairs:

the catalyst does not become clogged. Carbon deposits come out in the form of fine dust
cleaning with hydrogen does not require opening the engine
no additives, chemicals or other additives needed
no need to change oil after cleaning

Why hydrogen

It burns out carbon deposits deposited on the surfaces of the cylinders. Hydrogen ions react with solid deposits (soot), burn and are removed through the exhaust tract in the form of carbon dioxide, dust and steam.

Engine cleaning with hydrogen applies to all internal combustion engines. H2 services automobile, motorcycle, shipping, railway locomotives, aircraft engines and generators.

As a result:

fuel consumption is reduced
fall harmful emissions
vibration decreases
power and resource are restored
compression is normalized
injectors and spark plugs are cleaned

For new cars, the first cleaning should be performed after 50,000 km, subsequent cleanings should be performed every 20,000 km.

Almost every car owner asked the question: “How and with what help can you wash the engine of other contaminants?” During long-term use vehicle A large amount of contaminants of various origins accumulates in the engine compartment. Besides the aesthetic appearance, this problem important from a technical point of view. After all, a large accumulation of dirt in the power unit can affect the correct operation of the engine system. That is why it is very important to keep the engine of your vehicle clean.

Many owners turn to car washes for this service, where they clean with a jet of water under high pressure. power unit. This service has a low cost, but there is a possibility of water getting into the electrical equipment, which can disrupt the operation of the generator, starter and other important systems. In this article we will look at how, with what and in what sequence you should wash the engine from oil and dirt at home.

Why is dirt under the hood dangerous?

A car's engine is its heart. Even small accumulations of dirt and oil can cause it to malfunction. First of all, pollution affects the thermal regulation of the engine. As you know, the power unit largely consists of metal elements. Thus, layers of dirt and oil accumulating on the walls of its elements can contribute to overheating. In addition, in the engine compartment there is also a radiator responsible for. Large layers of dirt, dust, and insects accumulated on the radiator honeycomb will disrupt the heat exchange process.

Why wash the engine?

Let's look at the main reasons why it is worth monitoring the engine compartment and cleaning it in a timely manner.

Firstly, a power unit that is promptly cleaned of dirt, oil and other contaminants will last much longer. The engine requires proper operation of the cooling system, so it is important to monitor and clean it promptly.

Secondly, the accumulation of dirt accelerates the wear of engine parts. Large layers of dirt and oil begin the corrosion process, as a result of which small metal parts of the elements enter the engine oil. Thus, these contaminants circulate throughout the engine system and settle inside. This leads to a significant reduction in engine life, which leads to disruption of its operation, loss of technical characteristics.

Thirdly, in addition to the power unit, under the hood there is a large number electronic systems. Contamination can disrupt the operation of ignition systems. In addition, large layers of oil can lead to emergencies such as fire. Involuntary spark or impact exhaust gases may cause a fire.

I think that every car owner will agree that when you open the hood, it is much more pleasant to look at a clean engine.

Detergents

Any car, like a person, requires care and hygiene. Many car enthusiasts ask the question: “How to clean the engine?” Few people know that washing the power unit is quite a difficult process, which requires certain knowledge. After all, clean engine compartment It won't work with regular water and a brush. To perform this process efficiently, you must resort to using specialized means to clean the engine.

Many car enthusiasts use high-pressure water equipment to perform cleaning. The problem is that a high-pressure jet can cause mechanical damage to electrical equipment, wiring, and gaskets, which can result in engine failure. This method is quick, but there is a high risk of damage to electronic equipment and ignition systems.

In addition to the use of washing installations, the cleaning method with various fuel compositions, for example, kerosene, diesel fuel or gasoline, is also common among car owners. This method has a number of disadvantages. Gasoline is the most unsafe of the above mentioned products. It has a high risk of fire and produces explosive vapors.

Kerosene or diesel fuel, compared to gasoline, is the least safe for cleaning engine walls. They have a low degree of combustion, but create other unpleasant problems. After washing with kerosene or diesel fuel, the heating walls of the engine will begin to evaporate acrid smoke. This method is the least safe, and the evaporating smoke from kerosene will cause discomfort to the owner and passengers of the car.

More experienced car enthusiasts use specialized detergents to clean the engine at home. Each product is individual and has a different composition. This method is the most effective and safe, but even in this case you need to be careful. Chemicals can oxidize metal engine elements, as well as destroy plastic and rubber elements.

There is a huge variety detergents, intended specifically for external engine washing. There are two main types of chemicals for washing engines:

Means for removing various types of dirt (universal).
Means for removing a specific type of contamination, for example, to clean the engine from oil.

Such products are sold in the form of plastic or glass containers, or in the form of aerosols for spraying.

Chemicals are very individual, so it is very difficult to choose the most effective remedy for the cleaning. In most cases, a one-time use of such compositions will not bring the desired result, so washing is carried out repeatedly. Before choosing such a product, you need to carefully study its composition and it is better to give preference to more famous brands.

How to properly prepare a car for washing the engine compartment

Washing a car engine must be approached very responsibly, since this process requires knowledge of certain features. Improper cleaning of the engine compartment can lead to disastrous consequences.

To begin with, you need to choose a parking place in advance. The best place would be a garage. The choice of parking place is important, since after cleaning the car it is not recommended to use it for 10-12 hours. The engine needs to dry out.

In addition, it is necessary to check all electrical equipment for damage. Under no circumstances should there be exposed wires or other breaks or crevices where moisture could get in.

Prepare in advance all available and necessary means for cleaning.

If a place for cleaning has been chosen, all rules have been followed and available means have been prepared, then you can begin the cleaning process.

Step-by-step instructions for washing the power plant

To clean correctly and without consequences power plant must be adhered to following rules and act according to instructions.

Step 1. Preparatory stage.

First, you need to prepare all available means in advance. We will need: personal protective equipment, foil or polyethylene, tape, brush different sizes(medium and small, for hard-to-reach places), sponge, rag, cleaning agent, container with water, container for collecting remaining dirt.

Cleaning is carried out at an engine temperature of 50-60 degrees. If the engine has been started, then it is necessary to allow it to cool to the desired temperature. Otherwise, you need to start and warm up the engine to the specified temperature.

After that, using the prepared polyethylene or foil, we cover all the places where the electrical equipment is located and fix them with tape. We pay a lot of attention to the idle speed sensor, because if you overdo it and fill it with water, then there may be problems.

Step 2. Precautions.

IN mandatory personal protective equipment should be used. First of all, these are rubber gloves. Chemical cleaners can be harmful to your skin. In addition, contaminants in the form of oil are very difficult to remove. Therefore, rubber gloves and work uniform will be an integral part of this process.

Step 3: Apply Cleaner

We carefully read the instructions for the purchased cleaner.

First you need to rinse all contaminated surfaces with a small amount of water. Then the chemical is applied. If the product is in the form of an aerosol, then it is simply sprayed onto the required areas. If the product is in the form of a solution, then it is applied using a sponge. We recommend using a toothbrush to clean hard-to-reach places.

After application, wait the required time for the cleaner to interact with the contaminants. The duration is usually indicated in the instructions.

Step 4. Safety and environmental measures.

First of all, you need to carefully apply the cleaner. These mixtures are highly flammable and explosive, so safety regulations must be followed.

During the washing process, it is necessary to ensure cleanliness and not pollute the environment. If possible, any remaining dirt and oil should be collected in a container specially prepared for this purpose.

Step 5. Final stage

Finally, we rinse all the places where the cleaner was applied. It will be convenient to use a hose with low water pressure. It is worth noting that the engine compartment must be washed with caution, avoiding contact with electrical equipment, even though they are protected with polyethylene or foil.

After washing, we perform a visual inspection. If not all contaminants have been removed, then we carry out repeated cleaning.

It doesn’t take a lot of time or money to clean your engine from oil and dirt. You just need to follow the instructions and rules, and then your engine will shine and will not fail at the right time.

During operation of the car engine, coke and fumes are formed in the fuel combustion chamber at high temperatures. What it is?

How can you determine on your own that coke and fumes have accumulated in a car engine?

Coke is the name given to solid deposits on the walls of the combustion chamber that are formed when pierced without air flow. Cinder is small loose residues of such coke. Oil scraper piston rings are not able to cope with this task, so there is nothing left to do but clean the engine yourself.

Expert opinion

Ruslan Konstantinov

Automotive expert. Graduated from Izhevsk State Technical University named after M.T. Kalashnikov, specializing in “Operation of transport and technological machines and complexes.” More than 10 years of professional car repair experience.

Coke is the name given to soot, burning and tar deposits in an engine. Coke is formed for various reasons:
driving on low-quality fuel with a low degree of purification;
the use of various additives to increase the octane number, for example, some car owners use additives containing lead to increase 92 gasoline to 95 (despite the ban, it will not be difficult to find them on sale);
engine oil enters the fuel combustion chambers;
using motor oil that is not suitable for this type of engine;
driving on a cold engine with loads (especially important in winter time);
driving at low speeds (traffic jams).
These factors certainly contribute to the formation of coke. But even if you eliminate them all and use only highly purified gasoline, it is still impossible to eliminate deposits. It is an inevitable and natural product of engine operation. internal combustion.
Coke is dangerous because it disrupts the operation of the engine and gradually leads to the need overhaul. Soot on the walls of the combustion chamber leads to a decrease in the volume of the latter and the appearance of detonation, the strength of which will only increase with increasing soot.
Carbon deposits on the cylinder head prevent normal heat dissipation, which causes overheating. Coke on the valves makes the channels for exhaust and incoming gases smaller, and this affects the drop in power and dynamics. Due to carbon deposits, the valves cannot close completely; sooner or later this will lead to their burnout. But the worst consequence is a decrease in compression and the occurrence of all the accompanying problems due to coked oil scraper and compression rings on the pistons.

Note that when the engine is running, oil from the exhaust valves also flows fuel mixture. The higher the mileage of the car, the higher the likelihood that oil will enter the engine combustion chambers not only through the described route, but also through some other engine elements. That’s why you shouldn’t leave this work “for later.”

As soon as the first signs of “decoking” appear, immediately rid the engine of carbon deposits by removing coke from the entire surface of the car’s engine.

1. From exhaust pipe Smoke constantly flies out, and a specific smell appears in the cabin when the ignition is turned on. When does it start? cold engine, a “smoky” effect occurs.

2. Oil consumption is constantly increasing.

3. The dynamics of the car have decreased.

4. On Idling the engine runs unevenly.

5. During the cold season, the engine barely starts, although the battery is fine.

Decarbonization methods

In order to perform decarbonization yourself, you can use one of two methods.

The first of them involves pouring pre-purchased products into the engine cylinders through the spark plug holes, which loosen and remove coke deposits. This option is considered more effective, and it should be carried out on a warm engine.

In the second case, you should add the chemical to gasoline or oil. This method is less troublesome, but also less effective. If you still choose this method, then carefully read the instructions on the liquid packaging, noting how much of the substance, in what order and where to pour it.

Now let's look at the first decarbonization method in more detail.

Prepare a screwdriver and purchased smoke remover.

1. Remove all spark plugs.

6. Turn off the gear and be sure to crank the engine with the starter for at least 15 seconds to remove any fluid remaining in the cylinders. If you forget about this, the engine may be damaged due to water hammer. Before cranking the motor, secure the central high-voltage drive by creating a gap of a couple of centimeters between the ground and the tip of the wire. This will avoid breakdown of the ignition coil.

7. Tighten the spark plugs, return the drive to its place and start the car. Do not be alarmed by any difficulties starting the engine or the appearance of unpleasant odor after this procedure. Smoke may appear during the first 10 km of vehicle movement. You can drive when the car has been idling for about twenty minutes.

The formation of soot and coke in a gasoline or diesel engine is a natural process under conditions of high combustion temperatures of the fuel-air mixture in a closed chamber. In fact, soot is a layer of unburnt deposits on the walls of the combustion chamber of the power unit. Over time, carbon formation and coking of the engine progresses, at a certain point becoming the cause of a number of malfunctions and malfunctions.

Next, we will look at the main symptoms by which you can determine the coking of the engine and the need for further cleaning of the cylinders from coke, and we will also talk about how and how to clean the engine from carbon deposits with your own hands.

Carbon deposits in the engine: main signs

As already mentioned, carbon deposits and coke are formed in the combustion chamber during fuel combustion. Coke in the engine is dense deposits on the surface of the walls of the working chamber. Such deposits occur under the influence high temperature provided there is not enough air.

Soot is small crumbly fractions of the same coke, which are separated from the total mass. In addition to engine coking, engine oil enters the combustion chamber. Usually lubricant can penetrate into the cylinder through the piston rings, and also in the event of certain problems. In the second case common problem valve seals (valve seals) become.

In the list of main malfunctions that occur when the engine becomes coked, experts note the following:

the engine does not start well when cold;
after starting, the motor and/or is observed;
in some cases, the exhaust has a specific burning smell;
oil consumption increases;
the engine loses power;
excessive fuel consumption is observed;
on high speed Engine overheating may also occur;

During gas changes, especially on a car with a faulty or removed catalyst, you may notice burning particles flying out of the exhaust pipe. Also, the car reacts sluggishly to pressing the gas pedal, the engine “does not pull” under load, etc.

Engine coking: possible consequences

It is quite obvious that carbon deposits reduce efficiency and deteriorate the overall performance of the engine. In parallel with this, there is a risk of serious damage to the internal combustion engine. For example, critical situations can be considered those when the rings are heavily coked or the short-circuit effect () occurs. In the first case, the valve cannot close completely due to a thick layer of carbon deposits, a decrease in compression in the engine occurs, the engine begins to stall and starts poorly. Quite often, which leads to expensive repairs.

As for short circuit, this phenomenon causes uncontrolled ignition of the mixture in the engine cylinders from smoldering carbon deposits. In other words, the charge will not ignite from an ignition spark in gasoline engine or from contact with air heated from compression in, but spontaneously. As a result, the motor overheats, causing significant damage, etc.

To prevent negative consequences It is recommended to carry out periodic cleaning for preventive purposes, that is, to prevent excessive accumulation of deposits. Also, after the first symptoms appear, you can clean an already coked engine from carbon deposits, that is, carry out the procedure for decoking the engine. Let's take a closer look at how to clean carbon deposits in the engine yourself.

Methods for flushing the engine from soot and coke

Let's start with the fact that the engine can be cleaned in two ways, which can be divided into the following:

cleaning the engine using active chemicals;
mechanical removal of coke deposits after disassembling the internal combustion engine and subsequent washing;

Let us immediately note that on flushing oils and various fuel additives (up to connecting the motor to a separate tank with a special cleaning agent, bypassing fuel tank) we will not focus attention. The point is that these solutions help support fuel system, lubrication system, combustion chamber and other “insides” of the engine are relatively clean only in the case of new or initially clean engines (for example, units after a complete overhaul). If the engine has already been coked, then such methods will not bring the desired effect and can only worsen the situation.

To clean the internal combustion engine from carbon deposits, it is necessary to carry out a more “strict” procedure for decoking the piston rings and the engine, clean the combustion chamber as efficiently as possible, etc. Let us add that this method of cleaning the engine from coke and deposits is very popular among car enthusiasts due to the fact that it avoids disassembling the engine.

First you need to unscrew the spark plugs gasoline internal combustion engines or on diesel.
Next you need to fill special liquid(the so-called decarbonization) into the engine cylinders through the spark plug wells.
Then the unit with the cleaning solution filled is left for several hours. The result is a coke and carbon cleaner that softens engine deposits.
After screwing in the spark plugs and further starting the engine after decoking, the washed soot simply burns out in the cylinders.

The final stage of flushing the internal combustion engine is the mandatory replacement of engine oil and oil filter, since the aggressive composition enters the engine crankcase and makes the filled oil unsuitable for use.

You can read more about the engine decarbonization procedure in, where the process of cleaning the engine from carbon deposits is described in detail using an example. diesel engine. We also note that various products for decoking piston rings and cleaning the combustion chamber are available for sale. Among domestic consumers, a composition called “Lavr” has gained wide popularity.

Now let's talk about mechanical cleaning. This method allows you to achieve maximum engine cleanliness, and also does not have the disadvantages that are present when cleaning with “chemicals”. In other words, the motor is disassembled, after which coke and carbon deposits are removed from the surfaces manually, using tools, grinding, and also using active detergents. This approach allows you to clean not only rings and individual sections of the combustion chamber, but also valves, as well as other hard-to-reach elements. At the same time, the oil channels of the engine lubrication system are washed, the cavities in the crankcase, the oil receiver, the oil receiver mesh filter, etc. are cleaned.

What's the result?

It is quite obvious that the main disadvantage of the mechanical method is the complexity and impressive amount of work. For this reason, drivers rarely agree to disassemble the engine only to clean the unit from carbon deposits and coke deposits. More often, this procedure is performed during an engine overhaul.

Finally, I would like to add that it is highly advisable to consult with engine mechanics before you decide to clean the engine of coke and flush the combustion chambers of carbon deposits. The fact is that even the most aggressive chemicals do not completely remove deposits.

As a result, there is a risk of clogging the channels with particles separated from the total mass. Otherwise, in some cases it is better not to clean the engine at all, which will allow it to continue to be used for some time. If you try to clean such an engine from carbon deposits with special cleaners, then the likelihood of its immediate subsequent repair greatly increases.
