The engine decarbonization is an operation to remove carbon deposits from the engine using both mechanical and chemical methods.
The mechanical procedure consists in removing the head and therefore the physical removal of carbon deposits from the top of the pistons, the combustion chamber of other components (such as the valves).
In the past, two-stroke engines required frequent decarbation, since lubrication oil (usually 2-t oil) was burning in the combustion chamber, leaving the carbon residue behind.
The opening of the newspaper in two -stroke engines was a simple procedure compared to 4 -step engines. This process of decarbonisation of mechanical cars, if not performed by a qualified specialist, can involve additional costs, which is why the need for chemical decarbonisation is recognized.
The addition of some chemicals – such as alcohol and terpenes – a conventional fuel source (petrol /diesel) seems to dissolve and remove some of the carbon deposits formed in different areas of the engine group. Very often these are deposits in fuel injection systems, pistons, crowns, rings, combustion chambers, valves, exhaust collectors, EGR valves, route and shock absorbers. After removal, carbon is expelled from the exhaust system.
The steam cleaning of the components of an engine was presented as a method of low -cost carbonization method in which the water is injected into the air intake of the hot engine. The steam generated after this process should replace the deposited carbon and eliminate it by evacuation.
The efficiency of this method, as well as its positive and negative effects, have been discussed by specialists from all over the world, but as in the case of mechanical decarburation, if the method is performed erroneously, the engine is damaged.
Motor decarbonization is a preventive procedure that is performed when a vehicle exceeds 50,000-60,000 km. After the decarbonization, the duration of the engine has substantially improved. At the same time, improvements in terms of power, general performance and mileage can be observed.
Diesel engine decarbonization
The decarbonization of diesel engines aims to prolong the life of the most important power elements (group of cylinders, gas distribution and valves mechanism) and is also a compulsory preventive measure to be performed regularly, in accordance with all technological aspects.
Decarbonization of the petrol engine
The decarbonisation procedure is recommended to the petrol engine based on the induction system of the air suction system from:
- Wash the suction gallery;
- Wash the fuel tube;
- Injectors washing;
- Wash the combustion chamber and valves.
Before moving on to the engine decarbonization, it is necessary to diagnose the engine using a special tool. If after the diagnosis it was discovered that there is significant wear in the cylinder piston group, the decarbonisation procedure is not recommended.

How to do the engine decarbonization?
The main steps to follow in the engine decarbonisation process are:
1. To decarbonize the engine, pour the agent by reducing compression (to decal the oil scraper and the lower compression rings) through the oil filling neck, in the oil with which the engine was used. Its type differs from the degree of engine clog. Therefore, after starting the engine and heating it at 90 degrees, it is advisable to let it work for 20 minutes. This oil together with the washing will be used for the entire decarbonisation process.
2. Unscrew the candles and ruin their place the adapters included in the kit.
3. Connect the adapters to the device with a decarbonisation agent using the plastic pipes included.
4. Install the independent start -up unit of the appetizer by connecting a 12 V power supply and the control cable on the start -up terminal.
5. After connecting the control unit, screw the upper lid of the device with a decarbonisation agent, close the liquid power valves, screw the upper cover and turn off the air power valve. Make sure that all transparent fluid power pipes on the cylinders are well fixed and do not come into contact with the mobile parts of the engine.
Careful This liquid is corrosive! Respect the security measures!
6. Check to what extent the connection is correct. Open the liquid power valves on the adapters and turn the engine with the starter motor using the button on the control unit. Do it until the liquid appears in the transparent pipes from the device. Then pass the device in offline mode for 2 hours.
7. After three hours, turn off the autonomous appetizer, turn off the valves for the supply of fluids on the cylinders, pour the liquid used by the decarbonification device and fill with fresh liquid. Tighten the lid well.
8. Install the unit of independent order -Start -Start for another 2 hours.
9. After the next 3 hours, connect the compressed air to the adapter located at the top of the pressure device (6 bar) and turn the starter motor with the «Start» button on the control unit 10-15 times. In a diesel engine, after this operation it is advisable to stop the supply of the air supplied. Then unimallet the adapters from the candles, covering the holes with a cloth. Repeat the engine to start with the starter to completely remove the liquid from the combustion chamber.
10. Remove the BG equipment and install the candles.
11. Turn the engine and heat it at normal operating temperature. Let the engine work for 30 minutes at 1200-1400 rpm.
12. Empty the dirty engine oil and replace the oil filter.
13. Fill in 1 -liter BG120 and any engine or oil oil depending on the level.
14. Start the engine for another 15-20 minutes.
15. Drain the oil and replace the oil filter.
16. Empty the oil bath and clean it to remove carbon residues.
17. Whip the envelope normally and fill the engine with an appropriate and clean engine, with the addition of BG 110 or BG 112 oil modifier, depending on the engine. Therefore, for petrol engines they use BG 110 and for diesel ones it is recommended to use BG 112.
In addition, create complete fuel with additive cleaning (BG208/244) also depending on the type of engine (petrol or diesel).
Start the engine normally for 5-10 minutes in the ranks, then allow the engine to work under the load for 15-20 minutes (increase the speed from the 3-4 thousand rpm scarf).
Decarbonisation methods
As I said, there are the following types of engine decarbonisation, that is to say:
- Mechanically – According to the mechanical/physical technique, components such as the head, the suction and evacuation valves are open, so that carbon warehouses can be removed manually.
- Chemically – It can be performed by means of medium qualified mechanics, the method involves the use of alcohol -based chemical compounds. The chemical method must be used only as a preventive method because large deposits are better removed.
Chemical decarbonisation (with hydrogen)
The method of decarbonisation of the hydrogen of the engine lasts 1 hour. The method also helps in the case of serious bumps and the cost is much lower than any other alternative method. Furthermore, it is not necessary to disassemble any component of the engine, the cleaning of the hydrogen engine is very efficient. Desert with the chemical cleaning through which the cox is washed, often only in the upper layer, in the case of hydrogen the ration of Pyrolysis completely destroys the carbon warehouse, without reacting with other elements. The remains are expelled through the exhaust system.
Mechanical decarbonisation
As I said, the mechanical decarbonisation is performed by dismantling the components and cleaning the carbon residues.
A safe method of mechanical cleaning is ultrasound. This is relatively safe for cleaning the parts. The slag layer is crushed, the geometry of the piece is not disturbed, the gaps do not become larger.
The inconvenience is that ultrasound cleaning stations are expensive.
How much does the engine decarbonization cost?
The engine decarbonisation costs differ from one service to another depending on several factors, such as: for example:
- The devices used;
- The decarbonisation methods used;
- The level of qualification of mechanics;
- The type of service etc.
Basically, the costs differ from one engine to another, generally depending on the degree of carbon and its general wear. As an estimated reference price, depending on the cylindrical capacity, it drops by about 250 she for cars with engines lower than 2000 cmc and 300 she for those with over 2000 cc.
There are also seminars on street corners that can perform the operation at a cost of 100 Ron but runs all risks.
What is our opinion, is it worth it or not?
Once you understand what the engine is decarbonate and what are the ways to perform this operation, you can make a better decision regarding the methodical method. Specialists recommend the decision to decarbonize the engine to take it after having previously tried the other resolution methods.
Decarbonisation is necessary for aging vehicles. In the case of cars that traveled a few kilometers, it is not recommended at all.
Consequently, given the risks involved, it is recommended to choose the good service to perform this decarbonisation procedure.
