Using the vehicle exclusively in urban environments can lead to the formation of carbon in the cylinders. This is also facilitated by the regular consumption of low-quality fuel by the vehicle and frequent overheating of the engine. In this case, it is required to decode the piston rings.

This operation can be performed independently in the garage. However, for its implementation will require dismantling the cylinder block. The main features for performing this procedure are:

• increased oil consumption, while the exhaust gases will be significantly smoked;
• reduced compression in the engine cylinders is checked by a special device.

Basic concept

Removal of the resulting soot is called de-coaling. Such an undesirable product of combustion (carbon or coke) is formed by burning oils or fuels. Oil can enter the combustion chamber through the gaps of the piston rings or under the valve seals.

Nagar on the cylinder head

Both options are "treated." In the first case, a major overhaul is often required, and in the second situation it will be sufficient to replace the caps. Although most often carried out decorating rings with their own hands without the participation of specialists from the service station.

The procedure helps to delay the “capital” for another 30-35 thousand kilometers.

The essence of the problem lies in the fact that in addition to the soot formed on the cylinder walls, there is coke in the grooves of the pistons. It blocks the elasticity of the rings, due to which gaps are formed. Oil is ineffectively removed from the surface of the cylinders and into the chamber. The process repeats and aggravates the consequences.

Causes of soot

List of aggravating factors:

1. short trips over short distances;
2. operation of the power plant with low-quality engine oil;
3. irregular oil change;
4. significant overheating of the motor.

The consequences of improper operation

Visually, the need for decarbonization can be identified by the following features:

1. increased fuel or oil consumption under the same operating conditions;
2. black smoke coming from the exhaust pipe;
3. a clear drop in car power.

The use of special equipment

The carbon that has formed in the cylinders is urgently required. For this purpose, a special tool is used for the de-boning of piston rings. The most effective technology for working with such reagents is considered to be filling into the cylinders of the block. There, these substances loosen the coke, and then wash it off the surface.

Means for decorating the Lavr

Sometimes reagents are mixed into fuel or oil. But this option is undesirable for the fuel system and is used in extreme cases. Of the most popular funds are Hado, Lavr, Titan.

Algorithm of the operation

Before proceeding with the cleaning manipulations on the motor, it is necessary to warm it up. All operations should be carried out with a warm engine. You will need to purchase a decoder beforehand.

1. Unscrew the candles from the cylinders.
2. We expose all pistons approximately in one position. Usually, for this purpose, in the garage conditions, the drive wheels are jacked and the gearshift lever is set to a higher one. After that, scroll the wheel to install in the desired position of the crankshaft.
3. A medical syringe injects the required dose of a chemical reagent into the hole from the candle. The proportions for each substance are indicated on the labels or instructions.
4. For more effective interaction of the cleaner with carbon, it is recommended to turn the wheel a few degrees from the pouring point in different directions. The total dissolution process usually takes about a quarter of an hour. During this time, 3-5 times in 1-2 minutes you need to rotate the wheel..
5. We “tilt” the high-voltage cable from the ignition distributor, and fix the tips to a few mm from the “mass”.
6. Rotate the crankshaft with a starter for 10-15 seconds. This is done necessarily to get rid of excess fluid from the cylinders. If you skip such an operation, then after the twisting of the candles can occur water hammer.
7. Having got rid of the reagent, screw the candles into place.

Now you can return the connection coil in place and start the engine. For a short time you need to warm up the engine at idle for 15-20 minutes.

During this interval smoke may appear with a specific odor from the exhaust pipe.

Such a process is considered acceptable.

Other motor handling options

Before the advent of special means, countersink was carried out on the countersink with kerosene. To do this, it was created a mixture with acetone in proportions of 1: 2 or 1: 3.

Self-decoupling motor

For a four-cylinder engine, 200-300 ml of such a “cocktail” was needed. Filling was also carried out through the candle holes. The term was much longer. Had to wait from 8 to 12 hours. The final procedures are carried out the same way as when using automotive "chemistry".

Distilled water is another option for decontamination. This engine decarbonization with water begins when a medical dropper is connected to the throttle body. The frequency of falling drops is set at about 2-3 per second.

With this arrangement, you can drive a few hundred kilometers, and then check the degree of cleaning, removing candles.

Water cutting

As a water tank, some car owners use expansion tanks. Daily water consumption with this design is about 10 liters. Not everyone uses distilled liquid. But in order to filter the garbage there is enough filtration net in the drip itself.
