Daily use of the car in the city is a very serious test and load, even for the most modern engines. Constant switching of start-stop motion modes, operation on low-grade fuel and other consumables, an oil change process that was not carried out according to the regulations - all this can lead to the need to urgently engage in engine coking. In the market of automotive chemicals, there are special tools for sizing piston rings. Let's look at what these substances are, how to use them, how effective they are.
Causes of coking of combustion chamber parts
Sludge, which is formed on oil scraper rings and in cylinders, does not occur on its own. There are several main reasons that lead to its formation and the need for urgent deoxidation.
One of these is non-compliance with the regulations of the car manufacturer in matters of oil change. Some motorists with a view of economy fill in low-quality oils. Sludge will actively form if the motor often operates at elevated temperatures due to insufficient cooling. If the engine is subject to overheating, boils quickly, then it definitely needs coking. Also, carbon deposits are formed through the use of low-quality additives. If the machine has stood for a long time and has not been used, then before starting operation, professionals recommend replacing the oil and using some kind of liquid to deoxidize the rings. If the car is used without interruptions, and the listed problems never occurred with it, then the rings and other elements of the combustion chamber are coked due to mileage. This usually happens after 300 thousand kilometers.
How to determine if there is carbon deposits on the rings and in the combustion chambers
Defining this is pretty simple. There are several typical symptoms that indicate a problem. If compression has decreased in one or more of the combustion chambers , this definitely indicates coked parts. Also, increased oil consumption - about 300 g per 100 km can tell about the need for sizing. And finally, you should pay attention to the smoke from the exhaust system. It will be either white or blue. If these symptoms appear in the car, then it is urgent to use any available means for decoking the piston rings. It is not recommended to use a car that has soot in the combustion chambers. Such operation will lead to severe wear of the parts of the cylinder-piston group. If you do not perform the procedure for the destruction of soot on time, then cracks can form in the cylinders. In this case, the solution is only a major overhaul.
Tools for sizing of engine piston rings
Today, there are many different specialized products on sale. The most famous are the deoxidizer "Laurus" and the products of "XADO". These tools have become popular due to their low cost and quite decent consumer characteristics.
When choosing a tool, pay attention to how many cylinders are designed capacity. Often, such products are produced in small tubes of 10-15 ml. One such tube should be enough for only one cylinder. When purchasing a piston ring breaker, you should also pay attention to the type of motor for which the product is suitable.
"Laurel ML-202"
This is also a fairly well-known product. The product is supplied in the form of a liquid and is intended for CIP to clean all parts of the cylinder-piston group from soot. The manufacturer claims that this tool for decoking the piston rings can thoroughly clean the rings and grooves. This will restore the compression characteristics, as well as remove harmful deposits from the surface of the combustion chambers. Another product is able to eliminate ignition and detonation.
The drug is available in packs of 185 ml. This will be enough to clean the engine of up to two liters from soot. For large volume engines, 330 ml packaging is available. In fact, the deoxidizer "Laurus" is a fairly high quality preparation. And this is very nice, because it is made entirely in Russia. "Laurel ML-202" really has all the properties that are declared by the manufacturer.
How does it work
When liquid enters the engine cylinder, a special steam cap is formed on the heated engine.
It acts on deposits. Then the liquid seeps through the piston, removes carbon deposits. Within one hour, the coking of the Laurus rings is able to turn deposits into a loose formation, which easily flies out of the cylinder and then burns out.
Vins Cleaner
This product is designed to restore compression by dissolving and completely removing carbon deposits and deposits from the walls of cylinders and valves. The manufacturer reports the following characteristics: the drug is able to restore valve mobility, and can also prevent detonation. The tool is able to dissolve and remove deposits from the walls of the cylinders, grooves of the piston rings. Also plaque inside the intake manifold is removed. This product is a piston ring breaker. It is used using special equipment.
If you strictly follow the manufacturer's instructions, then this composition will please the result.
Liqui Moly OiI-Schlamm-Spulung
This product cleans the engine of carbon deposits through a lubrication system. The product removes sludge, reduces the amount of deposits on the details of the piston system. The composition is able to restore the mobility of the rings. Declared and the restoration of compression along with the cleaning of lubrication channels. The composition is suitable for use on both gasoline and diesel engines. In fact, such means for decoking piston rings are nothing more than an additive in the lubrication system.
As for the effect of the application, the tests show zero results. The tests performed did not reveal changes in the readings of the compressometers. Therefore, we can easily conclude that this drug is ineffective.
Folk methods
Products for sizing, which marketers offer car enthusiasts, do not always have a special composition. Very often, the product is a mixture of acetone and kerosene. It can be made independently. So, two parts of acetone and one part of kerosene are mixed at the rate of 150 ml per cylinder. Raskoksovka rings kerosene - a very effective way.
Engine flushing fluid
Along with deoxidizing agents, there are also commercially available flushing fluids for the entire engine. In each motor, carbon deposits and tar are formed during operation. During operation of the power unit, the lubricant oxidizes and forms a film on the parts of the lubrication system. Other impurities stick to it. Over time, these films turn into carbon deposits. All this leads to wear. Particularly dangerous are deposits that have accumulated in pressure reducing valves, hydraulic lifters, on the oil intake grid.
To combat these deposits, there is a special flushing engine "Laurus". This drug will remove all accumulated deposits and give the motor a second youth. There is a whole series of these tools. These fluids with different efficiencies clean the motor of soot. Tools must be poured into the vehicle's lubrication system. For example, flushing the Lavr Lux engine is ideal for all types of motors. It gently and safely removes any deposits. Especially the liquid is suitable for those units that have not been washed for a long time.
Summary
Raskoksovka contributes to a long and reliable operation of the engine. This is the cleaning of the motor from deposits and deposits, the presence of which leads to increased wear of parts and assemblies. You can use homemade liquids or use factory preparations that have proven themselves well (for example, Laurel products).
