Diesel engine decalification: procedure and price

Descaling a diesel engine involves cleaning up the carbon that has accumulated in it. It is carried out using an additive that needs to be poured into the tank, or a hydrogen machine in the garage. When your diesel engine is clogged, descaling is necessary to restore it to normal operation.

⚙️ How does diesel descaling work?

Le descaling the enginewhether it is a diesel or gasoline engine, it is necessary to remove calamine... This is a carbonaceous residue, similar to soot, which gradually settles on the walls of the engine after the combustion of the engine.

When too much carbon builds up, your engine can no longer function properly. Completely clogged, may fail. Until then, you will experience loss of engine power and excessive diesel consumption.

Good to know : carbon affects more than just your engine. It also clogs your turbocharger, particulate filter or EGR valve.

Descaling a diesel engine helps restore performance and prolong its life, but also fights against contamination. Therefore, it is important.

There are different types of descaling:

• Welling : you can clean your diesel engine by driving at a certain speed;
• With additives : they are usually poured directly into the tank to attack the scales;
• Descaling with hydrogen : performed by hydrogen apparatus, no chemicals.

Descaling with hydrogen is most effective. It consists in supplying a mixture of hydrogen and oxygen to the air intake when the engine is idling. This mixture will take off and burn carbon to cleanse your diesel engine.

🚗 Why descale a diesel engine?

All diesel engines, old and new, are at risk of clogging. Gasoline engines are not protected, but those that run on diesel are even more susceptible to this. Indeed, for self-cleaning, the diesel engine must be heated regularly.

If you use your diesel engine mainly in the city, unburned fuel particles cannot be removed and deposits form: this is called calamine... This will prevent proper air circulation in the engine and the removal of exhaust gases.

Ultimately, you run the risk of failure if you do not descale the diesel engine. But before we get there, you run into other problems: worried about starting, From power losses, excessive fuel consumption.

Carbon dioxide can also damage other parts of your vehicle, such as the turbocharger, injectors, or the EGR valve. Replacing them is much more expensive than descaling.

🔧 How to descale a diesel engine while driving?

Too frequent low speed circulation (less than 2000 rpm) and poor diesel quality contribute to the formation of carbon deposits. When the engine is too dirty, it is necessary to descale it. But you can prevent the build-up of deposits or clean the diesel engine that is not yet too dirty.

Required material:

• Additive
• Machine oil
• fuel

Step 1. Refuel with quality fuel

The first thing to do to avoid fouling your engine too much is to choose a good quality fuel. Indeed, thanks to the additives they contain, premium diesel engines limit the formation of carbon dioxide and therefore extend the life of your engine.

Step 2: Add Supplements

Another solution to prevent clogging of the engine is to add additives to the fuel. Additives are sold at service stations or auto centers. These cleaners help to partially get rid of scale. Adding an additive to your fuel couldn't be easier: simply unscrew the canister and insert the additive directly into the fuel tank.

Step 3. Avoid short trips (less than 5 km).)

When you drive very short distances, your diesel engine does not have time to heat up and therefore self-cleaning: it gradually becomes dirty. To clean a diesel engine, it is recommended to regularly drive on highways where you can drive at high speeds, and thus ask the engine to clean it.

Step 4. Change engine oil regularly

When your engine oil is too old, it contributes to the accumulation of debris. Change your oil at least once a year, and more if you drive a lot. To learn how to change engine oil, you can read our article on this change.

🚘 When to descale a diesel engine?

Before you take your car to the garage, make sure it really is a carbon problem. A diesel engine that needs to be descaled has the following symptoms:

• Your the car has problems starting ;
• Your car's engine lack of power and it takes time to react;
• Your fuel consumption increases ;
• One blue smoke thick comes out of your exhaust pipe;
• Le engine warning light burns;
• Centerpiece such as turbo, EGR valvethen particulate filterthen Cylinder head gasket or injectors I can let you go.

💰 How much does it cost to descale a diesel engine?

The price of descaling a diesel engine depends on the equipment used. When descaling with hydrogen, calculate the average 90 €, depending on the type of vehicle. The operation takes about 2 hours. When descaling with cleaning additives, the product is taken into account. from 20 to 80 € depending on brand and quantity.

That's it, you know all about diesel descaling! As you can imagine, this is an important operation to keep your diesel engine running and running. So don't hesitate to turn to our garage comparator for an inexpensive descaling solution near you!
