Characteristics of the Laurel decarbonizer and instructions for independent use

Author: Ivan Baranov

Engine decoking agent “Lavr” is a chemically active liquid designed to remove tar, coke and carbon deposits on piston oil scraper rings. By thoroughly cleaning these elements, the product does not have a negative effect on the paintwork of engine parts and is neutral to oil seals and gaskets. Despite the safety of the product, it is advisable to use this additive no more than every 100 thousand km.

TECHNICAL SPECIFICATIONS

Engine decoking liquid
PURPOSE: means for in-place cleaning of the piston, piston rings and combustion chamber parts.

PROPERTIES: cleans piston rings and grooves, restores compression, removes harmful deposits from the surface of combustion chamber parts, eliminates glow ignition and detonation (caused by carbon formation).

APPLICATION: intended for decarbonization of any diesel and gasoline engines.

How much does Laurel cost?

You can buy a decarbonizer at the following cost:

CONSUMER ANALYSIS

PROCESSING TECHNOLOGY: you will need to install the car on a horizontal platform (in this case, the cylinder axes will take a vertical position, provided that the engine is in-line and not opposed) and warm up the engine to operating temperature. Sequence of actions: turn off the power unit, unscrew the spark plugs (gasoline internal combustion engine), injectors and glow plugs (diesel internal combustion engine). Pour 45 ml of the drug into each cylinder, then immediately close the technological holes (you can screw in the previously removed spark plugs (nozzles)) to form a “steam bath” in the combustion chambers. Then you should turn off the ignition system (short-circuit the central wire, remove the connector from the Hall sensor, etc.) to avoid sparking and possible ignition of the decarbonizing agent LAVR (LAVR) ML-202.

Leave the engine for 1 hour. After the time has passed, release the technological holes. Turn the crankshaft with the starter 2-3 times for 5-10 seconds with the accelerator pedal fully depressed to remove excess liquid and vapor from the cylinders. Install the dismantled components and parts. After this, start the engine and let it run for 5-10 minutes in variable speed mode (idling with revving), but it is not recommended to “spin” the engine by more than 2/3 of the maximum speed. Replace used oil.

DOSAGE: standard packaging of LAVR (LAVR) ML-202 contains 185 ml of decarbonizing liquid (enough to treat an engine with a volume of up to 2 liters). If the volume is larger, you will have to use a 330 ml bottle.

SUMMARY

An inexpensive drug of high quality and, what’s nice, it’s made in Russia. LAVR (LAVR) ML-202 really has all the properties declared by the manufacturer. The results of the application can be found in the table.

LAVR is an excellent thing, I recommend it to everyone for uneven compression across the cylinders (as a result, vibration is possible) and simply for its (compression) reduction due to coking.

In crisis conditions, many people are put in a rather tough position, from ordinary citizens to representatives of big business. The automobile market turned out to be the most susceptible to various problems, and difficulties began to appear on it at the end of 2014, because it was from that time that experts noted an increase in the service life of various cars. Every person today tries to delay as much as possible the moment when his old, proven car needs to be replaced with a new car, using a wide variety of means, one of which is “Lavr” decarbonization. Reviews about this product can be found mostly positive, but in order to finally decide on a purchase, you need to understand the principle of action and the benefits of this product.

Today, a car service is a place where drivers prefer not so much to fix various malfunctions, but rather to prevent problems related to the age and mileage of the car. An intermediate means of such prevention is specialized auto chemical products.

Laurel: engine flushing, instructions, features of use

Let us immediately note that there are a large number of solutions for flushing the lubrication system on the market: Liqui Moly, Lavr, Xado, Hi-Gear, etc. You can also find so-called flushing oil, while in the Russian Federation drivers usually choose Lukoil or Zic.

Given such diversity, we decided to focus on one of the most widely represented and most popular products among engine flushes. We are talking about products under the Lavr brand.

By the way, we note that among the various products for flushing internal combustion engines, foreign companies usually do not offer the consumer ready-made flushing oils. The fact is that in Europe and other developed countries it is unprofitable to produce and use such oils. There is also an additional need for their disposal after use. It is much more rational to add active flushing to the used oil, which then still needs to be drained, as during a regular replacement.

As you can see, the most convenient and widespread is a preparation for flushing the oil system, which:

• poured directly into the mining;
• does not react dangerously with motor oil;
• maintains the required oil viscosity when flushing;
• effectively removes sludge and other deposits;
• does not have a pronounced negative effect on oil seals and seals;

First of all, although manufacturers of washes claim that their formulations do not affect the oil itself and simply improve its cleaning ability, in fact this is not the case. In practice, oil dilution still occurs. This means that you cannot load the engine while using flushing, that is, the unit should only operate at idle. Otherwise, reduced viscosity can lead to accelerated wear and engine failure.

As for the LAVR line of engine oil flushes, experts took this feature into account. As a result, the wash contains a so-called viscosity corrector. In fact, it is a polymer included in the composition that prevents severe liquefaction.

Another feature is the residue in the engine that cannot be drained

It is important that this residue, which is a mixture of waste and washing, is minimal and does not affect the fresh oil. To do this, first of all, the flushing needs to ensure maximum fluidity.

If we talk about the Laurel line of cleaners and rinses, we should highlight the following products:

• Lavr “Classic” five-minute wash for cars and trucks, as well as other types of commercial vehicles. There is also a more intensive 7-minute washing of the Lavr engine.
• Soft flushing of the Lavr engine, designed for the internal combustion engine to be operated under moderate load for 150-200 km.

Article on the topic: The gearbox crunches when changing gears: possible malfunctions

For a number of reasons, drivers often choose LAVR Motor Flush Soft 200 km. Its main difference is that you can drive with such a wash, it does not evaporate, and it also removes dirt more effectively than 5 and 7-minute “fast” compounds.

In other words, the mild oil system cleaner Lavr allows you to clean the engine for several days over 200 km, being an alternative to flushing oil. In this case, the internal combustion engine is operated under moderate loads during flushing.

How did she appear?

Immediately after various cars began to actively spread in the USSR, every owner knew that it was necessary to periodically clean the piston rings from various contaminants. At the same time, fuel in those days burned much worse compared to today, and sludge formed on the surface of parts quite quickly. Today, everyone can do decoking with “Lavr” to get rid of such faults, but back then they had to come up with something else.

The oil was also of much lower quality, so it oxidized quite quickly on the cylinder walls, forming a film and getting into the piston grooves. Among other things, during the combustion of fuel, soot gradually formed, mixing with this film, thus forming extremely persistent solid deposits that block the operation of the pistons.

Motorists tried to combat such pollution by any available means, for example, leaving kerosene in the engine overnight, and over time they began to use special solvents more often. Desperate car owners did not stop at the risk of being left without any means of transportation. In addition, the effectiveness of such compositions was practically absent, and even today many car enthusiasts are not afraid to experiment to their own detriment. Some have completely forgotten that such a procedure needs to be carried out, relying entirely on additives that are added to modern oils, as well as relatively high fuel standards.

Correct amount of liquid

Experts recommend not saving too much on money. Use the mixture in such an amount that it is enough to completely wet the car pistons.

Reviews of the Lavr ML-202 decarbonizer indicate that nothing will happen to the engine if you exceed the dosage by fifty to sixty milliliters. However, experts recommend taking this issue seriously and still monitoring the amount of fluid consumed.

How does LAVR help delay major repairs?

It is quite natural that engine overhaul is the most terrible event for most car enthusiasts, since this is a colossal expense, and the need for such a procedure indicates that the car is currently completely unsuitable for use. That is why, in order to avoid such situations, a special decarbonization “Lavrom” is used. Reviews say that the savings with the help of such a product are quite noticeable, because today the cost of overhauling most middle and budget class cars fluctuates around 50,000 rubles, while the drug costs only 400. But this remedy is not a panacea that gets rid of the need for repairs, but only prevention, so it will be useful to understand whether serious savings are actually being achieved.

What do they say in the reviews?

Most people quite liked the product - the decarbonizer, and they note the positive effect of its use. Among the advantages of using this liquid are the following:

• Significant reduction in oil consumption during active pedaling (about 10-20%).
• After the Lavr diesel engine was decarbonized, many people's engines began to run quieter. In gasoline units the same effect occurs, and vibrations also disappear.
• The equipment has become more obedient at high speeds and accelerations, and also has a more pleasant sound.

Some people who used the Lavra composition for decoking say that they did not see any noticeable effect, and such products do not particularly help with problems that arise, and the rings are easier to replace than to carry out the indicated manipulations.

New trend of car services

It is worth noting the fact that today even many car services have gradually begun to include in their price list such a service as Lavr decarbonization. Feedback from experts on this matter suggests that this is quite a profitable activity, since not all car enthusiasts can carry out this procedure on their own, despite the fact that they have this opportunity. For professionals, this is not a labor-intensive procedure, and it can easily be carried out on the street, since it does not involve the need to place the car in a service center. Thus, many companies ensure genuine gratitude from customers and a more active flow of them, and, consequently, profit. All this is ensured by Lavr decarbonization. Reviews from experts indicate that the flow of cars for this procedure is almost continuous. The reason is that it needs to be carried out every year or every 30,000 km, which means that a person who has already carried it out is guaranteed to become a regular customer of this service.

Neglected cases

Of course, “Lavr 202” is a decarbonizer, reviews of which are mostly positive, a very effective remedy, but you should not think that it is universal and will help cope with any problems. Do not forget that this drug can only perform a preventive function, and if the engine is already quite worn out, then no preventive procedures will be able to return it to working condition. To do this, it will be necessary to carry out major repairs and replace worn out elements.

What are the advantages?

“Lavr” liquid for engine decarbonization is absolutely safe for various equipment, so its use completely eliminates the possibility of any conflict situations or complaints from customers.

The procedure is extremely easy to use, so the owner of such a business does not have to allocate additional funds to train specialists - just read the instructions for the drug and follow it correctly. If the “Lavr” liquid for engine decarbonization is dosed correctly, the consumption of the drug in a car service can even be recorded.

It is worth noting that this procedure was carried out by Soviet car enthusiasts, but LAVR is the first company to release the drug to the mass market, and at the moment there are no products that would surpass ML 202 in their technical characteristics. A separate advantage of this product is that that the car service does not need to allocate additional costs for equipment, since all the tools necessary for the procedure are included in the packaging of the drug itself, which is another significant advantage.

Do-it-yourself “soft” washing

In this case, there is no need to remove the injectors, since “Laurel” is added directly to the fuel. A half-liter bottle is poured into the tank before refueling. Next, it is advisable to fill in from 40 to 60 liters of gasoline and use it completely, again, without refueling. It is advisable to repeat the procedure every 2-3 thousand kilometers.

Again, “Lavr” for decoking piston rings will not help if the system is dirty. But if you use such a product on a new car, and do it regularly, then you can keep the fuel system clean for a very long time. This product has a number of advantages. Firstly, even a beginner can cope with such washing. Secondly, after use, a protective film is created on the walls of the parts, which prevents the formation of new carbon deposits for a certain time.

Modern engines do not require decoking

Of course, over the past few years the situation with oil and fuel has improved significantly, because in Soviet times, few could even start without using a blowtorch, but despite this, the problem of coking not only did not disappear, but also seriously worsened. Technologies have become more advanced, the gaps between the grooves and piston rings have decreased, but this ultimately led to greater vulnerability of modern systems. Also, a small layer of deposits ultimately leads to engine malfunctions; over time, deposits accumulate more and more, and the problems only become more serious - compression drops, detonation occurs, wear accelerates, and then serious breakdowns appear. If you are not going to spend money on major repairs, then proper decarbonization with “Lavr” can help.

Decoking of piston rings (“Lavr”): reviews

Skoda Octavia and other cars require this procedure to be carried out regularly. According to reviews, most people are completely satisfied with this product. Many car owners have noticed significant improvements in the performance of their iron friend:

• oil consumption has decreased significantly;
• Quieter motor operation.

However, some people did not notice any effect at all from the decarbonization procedure.

In any case, it is better not to take risks and carry out regular cleaning on time. This will help keep the engine running for many years. You can save as much as possible on major repairs.

Additives and flushing liquids

Many believe that these procedures save you from any problems, so decarbonization is not at all necessary. In fact, the most effective way to remove various deposits is through “immersion,” when the decarbonizing composition is poured directly into the cylinders. At the same time, getting to the technological holes is not so easy, and you have to use special tools, as well as create comfortable conditions for yourself (it is better not to carry out such work outside in bad weather). That is why it is recommended to decoke the engine during a scheduled replacement of spark plugs or oil.

Why do you need to flush the engine oil system?

So, even taking into account that the owner will use high-quality motor oil and change it regularly, contamination in the engine still cannot be avoided. The only thing is that the intensity of their formation will be reduced.

Also, one should not assume that by 80-100 thousand mileage, even under such “ideal” conditions, deposits will not accumulate in the oil system. The reason is oil residues that cannot be completely drained as part of the replacement, heavy urban use, etc.

It becomes clear that pollution cannot be avoided. At the same time, it is also clear that it is optimal to remove them in advance for preventive purposes at the initial stage, before any problems begin with the engine (noisy operation, knocking of hydraulic compensators, decrease in pressure in the lubrication system, etc.).

Let us also add that car enthusiasts who change their oil 20-30% ahead of schedule often adhere to the opinion that an engine flush is not necessary when changing the oil. It is based on the assertion that the oil itself contains an active package of detergent additives that wash the engine and lubrication system.

Yes, this is true, but only partially. The fact is that a package of alkaline and other detergent additives is available, but in many cases it is not enough. Detergent additives work after 3-4 thousand km, that is, much earlier than the moment when the driver changes the oil again.

It turns out that you can wash the engine with oil, but to achieve results using this method, you will need to drain fresh oil several times literally every 2-3 thousand km. Obviously, such a procedure is very expensive in terms of budget.

At the same time, above we discussed only motors that were not very dirty to begin with. It often happens that the power unit has a mileage of about 200 thousand km. and more, the oil was changed according to dealer regulations without adjusting for operating conditions, there are doubts about the quality of the lubricant itself, frequent transitions were made from one type of oil to another, etc. In this case, it will take a very long time to wash the engine with oil alone, or it will not be possible to achieve the desired effect at all without using a special engine flush.

Article on the topic: Vacuum brake booster - why is it so easy for us to brake?

Having decided that flushing is necessary, the question arises of which oil system cleaner to choose. You should also take into account some features of using engine flushes and contraindications that also exist. Let's figure it out.

The liquid must perfectly clean the surface

“Lavr” is a preparation that cleans medium and high degrees of coking, but it often happens that in old engines the deposits have already become so “bored” to the parts that they hold on to them like cement mortar, and even cleaning such systems is white Not recommended. It is also worth noting the fact that solutions that are too caustic can cause engine damage.

But in any case, LAVR is considered a more effective product compared to analogues and standard solvents.

Let's sum it up

However, positive reviews are much more common online. Decarbonizing Laurel rings can really restore their mobility. But a lot depends on the condition of the power unit and the amount of carbon deposits. In some cases, to achieve more or less noticeable results, it is necessary to perform several washes in a row. Only then will compression rates increase and oil consumption will decrease.

Separately, I would like to say a few words about the difficulty of decoking the Lavr engine. Reviews say that there are no problems with an in-line 4-cylinder power unit, but with V-shaped engines everything is somewhat more complicated. Of course, the essence remains the same, but setting the pistons to approximately the same position will be more difficult. Don’t forget about the ignition, which is installed separately on each unit. Otherwise, the decoking procedure is performed similarly to that described above.

So we figured out the “Lavr” product, instructions for washing and other important points. If you don’t have the time and desire to decarbonize the engine yourself, then you can contact a car service, preferably a proven one. There, specialists will perform high-quality flushing of the system. If the engine in your car is in-line, then this pleasure will cost you several thousand rubles. For V-shaped power units a little more expensive. Although it is better to try to cope on your own, because this requires a minimum of knowledge and tools. The main thing is to follow the instructions that are written on the Lavra packaging and the sequence of actions. Assembly is carried out in reverse order. After a “hard” flush, it is recommended to install new spark plugs and change the oil.

How is this procedure carried out?

Now let's talk about how Laurel liquid is used. Decarbonization (instructions below) does not take much time if you follow the instructions for this product correctly and choose the right dosage. The procedure itself is done as follows:

• The engine warms up to operating temperature, which should be more than 70 ⁰C.
• The ignition system is turned off. To do this, you can remove the connector from the ignition coil or Hall sensor. Thanks to this, you can get rid of possible ignition of the vapors of this drug, as well as damage to various elements of the system.
• The spark plugs are removed. If the procedure is carried out in a diesel engine, the glow plugs or injectors are removed.
• The pistons are set to a position close to the middle one, while the crankshaft must be rotated by the pulley nut or using the drive wheel when the gears are engaged. To determine the position of the piston, you can use a long feeler gauge inserted through the process hole.
• Using a syringe, pour an equal volume of Laurel decarbonizing liquid into each cylinder. After this, close the technological holes so that a “steam bath” is formed in the combustion chamber.
• Now we have to wait. For an express procedure, you need to wait at least one hour, but in case of serious coking, the exposure time of the drug should increase up to 12 hours. In order for the liquid to more efficiently seep into the lower part of the cylinders, the pistons can be periodically moved in different directions.
• Clear technological holes. The remaining liquid is removed with a syringe, after which the cylinders are purged with compressed air. Now you will need to fully depress the accelerator pedal, and then turn the engine shaft using the starter two or three times for five seconds. In this case, it is recommended to cover the technological holes with some thick cloth so that the decarbonizing agent for Laurel rings does not splash out.
• Install dismantled parts and assemblies. Be sure to additionally check for correct assembly.
• Start the engine and let it idle for 5-10 minutes to reach operating temperature. It’s worth noting right away that short-term smoke may appear, since the liquid for decarbonizing the “Lavr” rings remaining inside will burn out, and this smoke is not dangerous for the catalysts.
• Clean the engine with a product designed for flushing the lubrication system, or with a special product LAVR.
• To completely get rid of carbon deposits, it is recommended to drive the first few kilometers at slightly higher speeds.

This is the proposed decarbonization. The instructions are extremely simple, and the work can be carried out by experienced motorists in a garage, so if you are confident in your abilities, you do not necessarily need to turn to the services of car services.
