Carbon Deposits in The Engine: How they are formed and how to get rid of them?

Carbon deposits are deposits that build up in internal combustion engines. Problems with sludge buildup occur in gasoline and diesel engines. How is it formed and how to get it out of the machine?

Carbon buildup is one of the more serious engine problems. This leads to serious errors and worsens the work. But what is the reason for its formation?

How are carbon deposits formed?

Carbon deposits are formed by the combustion of a poor fuel-air mixture. In direct injection engines, the cause of valve deposits is the way the fuel is delivered. Due to the fact that gasoline repeatedly enters the chamber and does not wash the valves, carbon accumulates on it. This, in turn, causes restricted air access, which results in incorrect combustion of the mixture.

The appearance of carbon deposits is also the result of driving a car only around the city and for short distances. During such slow, monotonous and short journeys, there is no natural release of carbon deposits, resulting in their build-up.

Changing the oil also affects the build-up of carbon deposits in the engine. Delaying an engine oil change for too long promotes the formation of carbon deposits. In addition, to save on car service, we often use unprofessional services that do not pay attention to engine controller software updates.

Unfortunately, this leads to improper operation of the engine, and it is associated with improper combustion of the mixture, and this in turn is associated with the formation of sediment. Incorrect timing also contributes to improper combustion of the air-fuel mixture. Therefore, we must take care of these elements, especially the chain that may stretch.

Symptoms of Carbon deposit in the engine

The build-up of carbon deposits manifests itself in several ways. The following are easily recognizable to us: noticeable power loss, uneven engine operation and increased fuel consumption.

In addition, the appearance of carbon deposits on the valves is evidenced by problems with the ignition system (eg misfiring) and incorrect composition of the exhaust gases.

How can I prevent carbon buildup?

Since the main cause of the formation of carbon deposits is poor combustion of the mixture, it is clear that the engine needs maintenance. First of all, we must regularly visit the workshop which will take good care of the whole engine.

Not only do you have to take care of changing the oil and filters, but also all the work of the engine, including: the mechanic has to update the engine software.

How to remove carbon deposits from the engine?

The easiest way to get rid of it is called flush the engine. It consists of pouring the chemical directly into the machine. Usually, it is done during an oil change, if we pay a few tens of dollars.

Another way is the so-called engine hydrogenation. It consists in introducing the gas mixture into the unit, which will lead to an increase in the exhaust gas temperature.

Due to the higher temperature, the carbon deposits will be converted into gas and expelled along with the exhaust gases. However, this does not guarantee a thorough cleaning of the engine, as only the part through which the gas passes will be cleaned.

The best way to clean the machine is to disassemble the machine and clean all parts either manually or mechanically. However, this method is already used when the engine has a serious problem and cannot be cleaned in any other way.
