H2 company talked about cleaning the engine with hydrogen. The most effective means for washing a car engine How to clean an engine from carbon deposits

Also, engine oil and other technical fluids have a negative effect on rubber and plastic elements under the hood (wiring insulation, covers, seals, all kinds of plugs, etc.). If in the case of plastic there is a risk of spoiling appearance element, then rubber products soften, crack and collapse, that is, they cease to perform their functions.

For this reason, experienced car enthusiasts try to avoid heavy contamination of the engine. To solve the problem, some drivers practice washing the engine with Karcher, others wash the engine with dry steam. Also, many car owners prefer to wash the unit on their own, that is, at home. Moreover, in all cases, the main task is to prevent damage to electrical equipment as a result of moisture ingress. For this you need to know.

However, this is not all. In order to obtain better results after washing the engine, special cleaning compounds should be carefully selected. In this article, we will talk about how to wash the engine from the outside, as well as which engine oil cleaner is better to choose.

Engine cleaner from oil and dirt: why is it needed and features of choice

To begin with, dust and other contaminants that enter the engine compartment from the outside are not the main problem. Most often, the need to wash the engine arises due to the fact that the engine and transmission oil, working fluid brake system, Power steering, etc. in the process of active operation, it flows out.

Quite often, the driver himself spills oil, antifreeze or brake fluid past the filler neck while refilling. As a result, the material falls on the outer surface of the engine, the engine compartment becomes dirty. Further, the dust begins to actively adhere to the created streaks, forming a dense layer of oily dirt.

In high heat conditions, such dirt spreads intensively over surfaces. As a result, the thermal mode of the engine operation can be violated and. It is quite obvious that it will be difficult to wash off such contaminants with plain water, soap solutions or car shampoos.

At the very least, it will take a long time to get any result. For this reason, it is optimal to use a special cleaner for the external surface of the engine for these purposes. Given the fact that there are a lot of similar compositions on the sale for removing deposits, dirt and oil drips, do right choice can be difficult.

Moreover, each manufacturer promises that its composition will be the best solution. In this case, in practice, it may turn out that the product does not cope with the task at hand or allows only partially washing off the dirt. For this reason, a review and test of engine cleaners helps to determine the choice.

The best external cleaner for oil and deposits from the engine surface: test and comparison of popular formulations

As already mentioned, today on the market there are a large number of means for washing and cleaning internal combustion engines from the outside. Among the most famous solutions, it is worth highlighting the external engine cleaner Runway, Felix, Turtle Wax, Sintec, Kerry, Mannol, Kangaroo, 3ton, Grass, Abro, Liqui Moly, ASTROhim.

As you can see, there are really many compositions, there are products of domestic and foreign manufacturers. To select the most effective solutions from a popular list, experts have carried out comparative test engine cleaners.

In short, specially prepared dirt was applied to the previously prepared aluminum plates, which served as an imitation of the surface of the cylinder block and cylinder head. To prepare the contamination, the "working off" was used engine oil, then fine sand and salt were added there.

Additionally, separate scrapings of dirt were taken from real engines, after which everything was thoroughly mixed into a homogeneous mass. After applying such a mixture to the plate, it was placed in a thermal oven, where it was baked for 2 hours at a temperature of about 90 degrees Celsius, which is close to the actual heating of the ICE surfaces during operation.

How to wash and dry the motor yourself with improvised means. Basic tips and tricks for a safe do-it-yourself engine wash.

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

How to 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, which are formed when pierced without air entering. Fumes are small free-flowing residues of such coke. The oil scraper rings are not able to cope with this task, so there is nothing left to do how to clean the engine with your own hands.

Expert opinion

Ruslan Konstantinov

Automotive expert. Graduated from ISTU named after M.T. Kalashnikov with a degree in Operation of Transport and Technological Machines and Complexes. More than 10 years of professional car repair experience.

Coke refers to deposits of soot, burning and tar 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 with a lead content to increase the 92nd gasoline to the 95th (despite the ban, it will not be difficult to find them on sale);
engine oil enters the fuel combustion chambers;
use of engine oil not suitable for this type engine;
driving on a cold engine with loads (especially important in winter);
movement at low speeds (traffic jams).
These factors certainly contribute to the formation of coke. But even if you exclude all of them and use only highly refined gasoline, it is still impossible to exclude deposits. It is an inevitable and natural product of engine operation. internal combustion.
Coke is dangerous in that it disrupts the operation of the engine and gradually leads to the need overhaul... Carbon deposits on the walls of the combustion chamber lead to a decrease in the volume of the latter and the appearance of detonation, the force of which will only increase with increasing carbon deposits.
Carbon deposits on the cylinder head interfere with 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 most terrible consequence is a decrease in compression and the occurrence of all the attendant problems due to coked oil scraper and compression rings on the pistons.

Note that when the engine is running, the oil from the exhaust valves is also together with the flow of the fuel mixture. The higher the vehicle mileage, the higher the likelihood that oil will enter the engine combustion chambers not only in the described way, but also through some other elements of the engine. That is why leaving this work "for later" is not worth it.

As soon as the first signs of "decoking" appear, immediately remove carbon deposits from the engine by removing coke from the entire surface of the machine's engine.

1. From exhaust pipe fumes constantly fly out, and a specific smell appears in the cabin when the ignition is turned on. When does it start cold engine, there is a "smokiness" effect.

2. Oil consumption is constantly growing.

3. Decreased car dynamics.

4. On Idling the engine runs unevenly.

5. In the cold season, the engine barely starts, although everything is in order with the battery.

Decarbonization methods

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

The first of them involves pouring pre-purchased funds into the engine cylinders through the openings of the candles, 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, the chemical should be added to gasoline or oil. This method is less troublesome, but also less effective. If, nevertheless, you choose this method, then carefully read the instructions on the liquid packaging, noting how much substance, in what order and where to pour it.

Now let's consider the first method of decarbonization in more detail.

Prepare a screwdriver and purchased burn remover.

1. Remove all spark plugs.

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

7. Tighten the candles, put the drive back in place and start the car. Do not be afraid of any difficulties with starting the engine, or the appearance of an unpleasant odor after this procedure. Smoke can go on the first 10 km of vehicle movement. You can drive when the car has been idling for about twenty minutes.

Usually, washing means cleaning the body from external dirt and plaque. It can be done contactlessly or manually using a washcloth. Often this procedure is performed once every 1-2 weeks, depending on the frequency of vehicle use. But along with the outside, there is another type of sink. It concerns the engine. But, unfortunately, rarely anyone pays attention to him. Some motorists have been driving this way for years. But in vain. Today we will look at different products for cleaning a car engine.

How often should you do it?

There are no regulations here. The degree of regularity of this procedure is determined by the car owner himself. In practice, to maintain the cleanliness of the engine compartment, the engine must be washed once a year.

It becomes most polluted in winter, after driving on muddy, uncleaned roads.

Why do you need to wash?

Washing a car engine is not only an aesthetic moment. This procedure must be performed for a number of other reasons:

• Road dust and dirt that accumulates on the surface of the motor impairs its heat dissipation. As a result, the engine runs out of order. This increases the wear of its parts and affects the resource as a whole.
• In the case of oil drips (can form both under the valve cover and at the junction of the block with the cylinder head), dirt will adhere at an incredible rate. As a result, both the engine and its attachments, will be covered with a thick black coating. This makes it very difficult to visually inspect parts. Also, when oil gets on hot engine parts (exhaust manifold), it starts to burn. This provokes a sharp and bad smell entering the salon.

In order not to experience such problems, you should choose the best detergent for cleaning the car engine. Below we will pay more attention to this issue.

Types of funds

How to choose a detergent for washing a car engine? With your own hands, this procedure can be done with one of two types of funds:

• Specialized.
• Universal.

The first product is only suitable for specific types of dirt. For example, you need to remove oil deposits that have leaked due to a punctured crankshaft oil seal or some gasket. The tool will perfectly remove this pollution, but it will be powerless against the rest. Universal ones are used for complex cleaning. But sometimes, for a quality result, you have to repeat this procedure again. How to choose a DIY engine cleaner? Experts recommend using generic drugs. But in advanced cases, you cannot do without specialized ones.

Also, products are distinguished by the type of container. So, there are means for washing the engine in cans (usually 5 liters). It is very inconvenient to use them - you have to pour them into another, less voluminous container. The most suitable option is products in the form of a spray-spray and in cans. The product is sprayed evenly onto the surface and even reaches hidden cavities.

Restone heavy duty

It is a universal engine cleaner. Sold as a 390 ml aerosol can. The instructions for use are pretty simple:

• Warm up the engine to operating temperatures and then turn it off.
• Protect the power supply system (battery) and ignition (candles, coils) from moisture.
• Apply the product evenly over the surface.
• After ten minutes, wash off the product with running water.

As noted by the reviews, after application to the surface, the drug forms an active foam.

It easily penetrates into hidden cavities and holds well until rinsed off. Removes both dirt and oil deposits. But the product struggles with serious pollution. Summing up about the tool, we can say that the product is only suitable for preventive measures. In advanced cases, he is powerless.

STP

Sold in the form of an aerosol can. A volume of 500 milliliters is sufficient for several applications. The agent is used to clean engines passenger cars, minibuses and SUVs. The instructions for use are similar to the previous one (although there is no Russian language here), except for the waiting time. After applying the product, you need to wait about 15 minutes. You should also protect the batteries and ignition in the car.

In the course of application, the product has shown excellent results. After the first use, up to 85 percent of the deposits were removed from the surface. The product is highly commendable.

"Liquid Moli"

It is a spray cleaner. Sold in a 400 ml bottle. According to the instructions, after applying the drug, you need to wait 15-20 minutes and rinse everything off with a stream of clean water. Liquid Moli removes grease deposits, road dust, reagents and oily stains. According to the manufacturer, the product provides a 100% result. In practice, the original tool really did the job. But when buying, you need to remember that under the Liquid Moli brand a lot of fakes are offered at a reduced price.

"Laurel"

This is already a Russian product manufactured in Chelyabinsk. It is a concentrated universal cleaner. Has a foam composition containing emulsifiers and solvents.

Thanks to this, the product provides the maximum effect when cleaning the internal combustion engine. Removes oil and other contaminants and prevents corrosion. Sold in a 3-5 liter canister. Unlike the previous means for washing the engine, "Lavr" has a slightly different instructions for use:

• The concentrate is mixed with water in a one to three ratio.
• The engine warms up to operating temperatures.
• The air duct, power supply and other vulnerable elements are closed.
• The solution is applied using a spray bottle.
• After five minutes, the agent can be removed with a high pressure jet.
• In case of severe contamination, it is possible to use the concentrate without preliminary mixing.

Is "Laurel" the best engine cleaner? This is a very controversial issue. This tool is mostly suitable for specialized services, rather than for an ordinary car owner. The solution volume can be up to 15 liters.

This is a lot, since half a liter is enough for an ordinary car. Compared to the competition, the engine cleaner performs well. Up to 50 percent of the deposits can be removed the first time. The "cold" drug is practically powerless. It is applied only to a thoroughly warmed up engine, since the solution boils at 80 degrees Celsius. It is in this range that its maximum cleaning efficiency is achieved.

Precautionary measures

The respiratory tract should be as safe as possible before using this product. Vapors of such cleaning agents are very harmful to human health. Also, you cannot work with the product with bare hands - only through rubber gloves. If substance comes into contact with skin, wash the area immediately with warm water and soap.

As for the vehicle itself, the following vulnerable elements should be covered:

• Battery.
• Spark plugs and armored wires.
• Carburetor (if equipped).
• Air filter housing.
• Trambler (if available).
• Generator.
• Engine sensors and their contacts.

Attachments should be covered with cellophane or polyethylene.

Remember that water ingress may not always dry out the part. Liquid can enter hidden cavities and cause short circuits.

It is also not recommended to use " folk remedies for washing the engine ". These are gasoline, kerosene and other substances. They are not only ineffective, but also fire hazardous. Only specialized products in cans, sprays or in the form of a concentrate should be used.

Conclusion

Washing the engine is an important preventive measure that few people pay due attention to. Thanks to it, it is possible to identify oil drips and other problems in the course of vehicle operation in advance. The cost of cleaning products is very affordable. And any car owner can cope with this procedure.

It allows you to get rid of stains of dirt, oil, fuel, bitumen and other things on the surfaces of individual parts in the engine compartment of a car in a short time. Such cleaning must be performed periodically (at least several times a year, especially in spring and autumn) in order, firstly, to touch relatively clean parts in the event of repair work, and secondly, to minimize the ingress of contamination from external surfaces parts into the interior space. As for the aesthetic component, often car engine cleaners are used to perform pre-sale complex cleaning of the car.

The assortment of various car engine cleaners is currently wide enough on store shelves, and car owners use them everywhere. Many of them leave their feedback and comments on this application on the Internet. Based on such information found, the editors of the site have compiled a non-commercial rating of popular products, which includes the most effective cleaners. A detailed list with a detailed description of certain funds is presented in the material.

What are the purifiers

Currently, the range of car engine surface cleaners is quite wide. Similar products are produced by various manufacturers in different countries of the world. As for the state of aggregation of the cleaners, they can be found on the shelves of car dealerships of three types:

• aerosols;
• manual triggers;
• foam products.

According to statistics, aerosols are the most popular. Their popularity is due not only to their high efficiency, but also to their ease of use. So, they are applied to places of pollution with the help of aerosol cans, in which they are packed (after hitting the surface, the active agent turns into foam). As for the trigger packs, they are similar to aerosol packs, however, the trigger involves manually spraying the cleaner over the surface to be treated. Foam engine cleaners are applied with a rag or sponge, and are designed to remove stains of oil, dirt, fuel, antifreeze and other technical fluids that may occur on the surface of the engine compartment parts.

In addition to the type of packaging, engine cleaners differ in composition, in particular, in the base component. In large quantities, dodecylbenzenesulfonic acid (abbreviated as DBSA) is used as the main detergent; it is the strongest synthetic emulsifier of oils and fats, capable of removing even the dried substances mentioned from the surface being treated.

How to choose an engine cleaner

The choice of one or another external car engine cleaner must be made based on several factors. In particular:

• State of aggregation... As mentioned above, the cleaners are sold in three types of packages - aerosols (sprays), triggers and foam formulations. It is preferable to buy aerosol cleaners because they are easy to use and store. In terms of efficiency, they are also among the best. However, in this case, the type of packaging is not critical, because due to logistics, the range of stores in some regions of the country may be limited, and there will be no aerosol engine cleaners.
• Additional functions... In particular, in addition to good detergency, cleaners should also be safe for rubber and plastic parts that are abundant on engine parts (various rubber tubes, caps, seals, plastic covers, and so on). Accordingly, during washing, these elements should not be destroyed even partially. In addition, it is desirable that a car engine cleaner prevent the destruction of electrical wiring in the engine compartment by aggressive elements, and also prevent the likelihood of a fire. Aggressive elements mean fuel, solvents, salts and other elements that can get into the engine compartment from below or from above.
• Efficiency. External cleaner By definition, the engine should dissolve well the stains of grease, oils (greases, engine oil), fuel, wash off just dried dirt and so on. An additional efficiency of aerosol engine cleaners lies in the fact that the foam, spreading over the treated surface, gets into hard-to-reach places that cannot be reached simply with a rag. And its further removal can be done with water under high pressure... As for the effectiveness of the composition, information about it can be read in the instructions, which, as a rule, are printed directly on the packaging in which the product is packaged. It will also be useful to read the reviews about the cleaners of the car's internal combustion engine.
• Price-to-volume ratio... Here you need to think like when choosing any product. The amount of packaging should be chosen taking into account the number of planned surface treatments of engine parts. For a one-time treatment, one small balloon is enough. If you plan to use the product on a regular basis, then it is better to take a bigger bottle. This will save you money.
• Security... A car engine cleaner must be safe not only for rubber and plastic, but also for other parts of the car, as well as for human health, in particular, for his skin, as well as for the respiratory system. In addition, it is desirable that the purifier is safe from an environmental point of view.
• Ease of use... Aerosol cleaners are easiest to use, followed by manual trigger packs and regular liquid foams. When using the first two types, there is usually no need to touch the cleaner with your hands, since the application takes place at a distance from the contamination. As for foam cleaners, it is often necessary to wash your hands after using them.

Means for cleaning hands from dirt

After a car repair, your hands are always dirty, and the question of how to wash them is acute, because neither gasoline nor powder often helps. For such stubborn dirt, there are special auto-pastes. Here are the 10 best cleaning products

How to use cleaners

As for the most common aerosol and trigger engine cleaners, despite the differences in their composition and names, the algorithm for their use is the same for the vast majority, and consists of the following steps:

1. Disconnect the negative terminal with battery to avoid possible malfunctions or "glitches" of electronic components of a car engine.
2. Using a pressure of water under pressure or simply using water and a brush, it is necessary to remove dirt from the surface of the engine parts, which can be easily removed without the use of additional means. This will allow, firstly, to save the cleaner, and secondly, to increase its efficiency, without extending its efforts to remove minor contaminants.
3. Apply the product to the treated surfaces. Please note that this can only be done when the engine is cold, unless the instructions explicitly state otherwise (some funds are applied to slightly warmed motors). Aerosol cans must be shaken well before use. First of all, you need to apply the cleaner to the dried spots of process fluids - oil, brakes, antifreeze, fuel, and so on. When applying, special attention should be paid to hard-to-reach places, cracks, and so on.
4. Allow the product to absorb and carry out a cleansing chemical reaction for several minutes (usually the instructions indicate a time of 10 ... 20 minutes).
5. With the help of water under pressure (most often the famous "Karcher" or its analogs are used), or simply with the help of water and a brush, it is necessary to remove the foam together with the dissolved dirt.
6. Close the hood and start the engine. Let it run for about 15 minutes so that when its temperature rises, the liquid naturally evaporates from the engine compartment.

Some cleaners may have different time of their action (chemical reaction, dissolution), the amount of the applied agent, and so on. Before using any cleaner read the instructions carefully on its packaging, and be sure to follow the recommendations given there!

Tests by enthusiastic car enthusiasts show that the performance of the Kerry Cleaner is in fact average. So, in practice, it copes well with mud patches of average complexity. However, it may not cope with more complex, including chemical, pollution. To do this, you need to use more effective means or remove stains mechanically (in particular, using brushes and other similar tools). Therefore, this tool is more likely to be suitable as a prophylactic one, that is, it is used regularly to clean the engine, preventing the appearance of old and dried out stains that are difficult to remove on its parts.

Kerry Foam Engine Cleaner is sold in two different packages. The first is in a 520 ml aerosol can. The article for purchase in the online store is KR915. The price of such a package is 160 rubles. The second type of packaging is a bottle with a manual trigger. Its part number is KR515. The price of such a package is on average 100 rubles.

Fenom engine cleaner

Fenom belongs to the category of classic external cleaners, and it can be used to clean parts in the engine compartment, gearbox and other machine parts (and not only) that need to be cleaned of oil stains, various process fluids, fuel, and simply dried mud. In accordance with the instructions, before using the Fenom cleaner, it is necessary to warm up the engine to a temperature of about + 50 ° C, and then turn it off. Next, you need to shake the container well and apply the cleaner to the surfaces to be treated. Waiting time is 15 minutes. After that, rinse off the foam with water. The instructions explicitly state that both working foam and water must not be allowed to enter the engine air intake. Therefore, if possible, it is better to cover it with plastic wrap or similar waterproof material.

The performance of the Fenom engine cleaner is actually average. It does a good job of removing more or less fresh and uncomplicated (non-chemical) stains, but it may not cope with more stubborn stains. In this case, you can try to apply the product two or even three times. However, this, firstly, will lead to its overspending, and secondly, it also does not guarantee a positive result. Therefore, the "Fenom" cleaner can rather be recommended as a prophylactic agent, which needs to be treated with the surfaces of engine parts in order to prevent the occurrence of foci of severe contamination on them, including those caused by the spilling of process fluids.

The engine cleaner "Fenom" is realized in a 520 ml aerosol can. The article of the cylinder by which it can be purchased is FN407. The average price of a package is about 180 rubles.

Mannol engine cleaner

Under the Mannol trademark, two similar compositions are produced for cleaning the working surfaces of engine parts, transmissions and other elements of a car. The first is the external cleaning of the Mannol Motor Cleaner and the second is the Mannol Motor Kaltreiniger. Their compositions are almost identical, and they differ only in packaging. The first comes in a hand-trigger bottle and the second in an aerosol can. The use of funds is traditional. Their only difference is that it is easier and faster to apply the agent to the treated surfaces using an aerosol can. The foam from the aerosol is also slightly thicker, and better penetrates into hard-to-reach areas and pores of engine parts.

During the operation of the car, carbon compounds are formed on the internal surfaces of the engine and in the channels of the lubrication system. They are inevitable and cannot be solved simply by using engine oil. High Quality... Also, do not forget that when draining old, used oil, some of it remains inside the engine. How does this threaten the car?

When you fill the engine with new oil, the additives contained in it will immediately begin to interact with deposits and impurities. This can lead to a variety of negative impacts, including:

• partial clogging oil filter;
• premature development of the additive package, loss of performance properties of recently filled oil.

How to be in this situation? It is necessary to use special flushing agents, thanks to which the engine will run efficiently and smoothly after changing the engine oil.

How often should you flush? This should be done every time you change the oil or oil filter.

How to choose an engine cleaner? The obvious option is to use fresh engine oil. In this case, everything is simple: you need to drain the old oil and fill in the new one. After the engine has been running for some time, the oil used as flushing is drained and fresh is refilled. This approach provides good result, but it has a serious drawback - high cost. When you use oil as an engine flush, you pay twice for it.

The next option is to use a special flushing oil. Such a wash is poured into car engine after draining the old oil, after which it needs to work for about 15-20 minutes at idle. Typically this product is mineral based, which makes it affordable. Then you change the filter and drain the used engine flush, replacing it with fresh oil. Unfortunately, such funds cannot be completely drained, some part inevitably remains in the internal cavities, mixes with fresh oil, deteriorates its viscosity and other operational properties.

The best option is flushing, which is called "five-minute", as well as other similar products. This agent is a set of additives that is poured into old oil, mixed with it and effectively removes dirt and deposits formed in the engine. This flushing has many advantages. She:

• restores the mobility of compression and oil scraper piston rings;
• improves heat dissipation;
• minimizes engine wear, increases its resource;
• makes it easier to drain old oil.

Separately, it is worth noting the safety of such washes for rubber seals, oil seals, valve stem seals.

In some cases, it is necessary to use the so-called professional flushing, which can cope with the most difficult tasks of cleaning engines from contamination. How are they different from conventional products? In professional flushing, the content of active components is increased. They are recommended for use in the following cases:

• constant use mineral oils insufficiently high quality (flushing should be used at least once in three oil changes);
• severe overheating of the engine and the resulting formation of carbon deposits;
• frequent use of fuel of dubious quality;
• obvious engine malfunctions - poor start-up, loss of compression, smoke, and so on;
• significant excess of the oil change interval;
• constant strong knocking of hydraulic lifters caused by a clogged oil supply line.

For washing heavily worn engines, special products are used, designed for effective and at the same time gentle cleaning. The fact is that during cleaning, large fragments of deposits can form, which can harm the interacting parts. The use of special flushes allows you to transfer sediments and impurities into low-dispersed phases, which cannot damage the engine.
