The engine decarbonisation should be done from time to time, as it increases the life of the engine by a good margin and gives it a "new" feeling when done.
In this article, we cover the myths, beliefs and facts about the important topic of engine decarbonisation.
Engine decarbonisation literally means ridding your engine of all carbon deposits that could otherwise damage it.
By engine we mean the combustion chamber walls, the top of the piston, the exhaust and intake valves as well as the manifolds.
You may now ask yourself why carbon is deposited in all these areasGuess what? We have the answers ready.
One of the main reasons for the carbon deposition is the age of the vehicle. As the vehicle travels more kilometres, the engine wears down and some of the carbon sticks to the walls, valves, etc. as scale.
Another reason is the use of poor quality fuel or incomplete combustion of the fuel.
Another cause is the worn piston ringswhich, if not replaced, cause significant damage and carbon deposition.
Generally, for any vehicle (gasoline or diesel), decarbonisation is carried out when it approaches the 50,000 km mileage.
However, this depends on the engine make and some engines may even need decarbonisation sooner or later.
The range, however, is around the 40,000-50,000 kms mark.
Yes, the vehicle shows signs that the charcoal has affected its engine.
Firstly, there will be a noticeable drop in power output and an increase in fuel consumption of the vehicle.
You may even notice that the engine shudders or stutters and does not respond quickly to throttle actions.
This is because it affects the compression pressure of the engine and also blocks the valves preventing gases from flowing in and out smoothly.
Another visible side effect is the excessive smoke that the vehicle will emit, suggesting inadequate fuel combustion. This carbon deposition also fouls the spark plugs which, if left unattended, will need to be replaced frequently.
Engine decarbonisation can be done in several ways.
A rather simple process in which a mechanic pours a chemical cleaner in the fuel tank to clean the fuel path and also the engine components.
This cleaner cleans all dirt deposited on the engine.
This process can cost from 300 to 1000 or 1500 Euro depending on the make of vehicle and the service location.
This method is far from simple.
For mechanical decarbonisation, the engine must be dismantled and carbon fouling must be removed by discarding each layer.
This method is expensive and time-consuming and can cost you around 3000 euros. In some cases, the cost can be much higher.
Decarbonise the engine with a hydrogen decarbonising machineconsists of injecting a gas called HHO through the engine intake.
This gas will go through the whole system doing a pyrolytic cleaning of the carbon deposits.
The cost of this method can vary between 100 and 300 euros depending on the vehicle model, treatment time, etc.
This completes the main methods of engine decarbonisation.
One tip is to make sure your engine needs decarbonising and also make sure it is done by a professional.
If done incorrectly, it can even damage the engine, so be careful.
