DPF cleaner, particulate filter cleaning

Nowadays, cars are equipped with a particulate filter to help reduce the amount of pollution they produce. Over time, this filter can become clogged, reducing its effectiveness. One way to clean the filter is to use a DPF cleaner. These cleaners come in various forms, including aerosols, gels, and additives. Some are designed to be used while the car is running, while others must be added to the fuel tank. In short, here’s everything you need to know about DPF cleaners.

What is a particulate filter and what is its purpose?

It’s a device installed in the vehicle’s exhaust system to help it meet European emissions standards. Its main function is to trap and reduce the emission of fine particles contained in the exhaust gases.

The particulate filter can become clogged over time, which reduces its efficiency.

How do I clean a particulate filter?

To achieve this, you have a choice of four different methods: Passive cleaning, active cleaning, cleaning with an additive, and carbon cleaning.

Passive (curative) cleaning: This method is used when driving on highways or motorways for at least 50 km. Active cleaning: This method can be integrated directly into your car, depending on the model. The particle level is automatically analyzed, and when it exceeds a certain threshold, the filter will be cleaned by automatically increasing the temperature.

Cleaning with an additive: This method requires you to add the additive to your car’s fuel tank after filling it halfway. The additive will help clean the filter while you drive. Carbon cleaning: This method is the most effective, but it requires a professional with specialized tools. Using a carbon cleaning station, the mechanic can remove all the carbon deposits present in the engine and on the exhaust system, including the DPF (Diesel Particulate Filter). There is a fifth method, which is manual cleaning. This is the least recommended method because it can damage the filter if not done correctly. It involves removing the filter and cleaning it with compressed air, water, or another suitable solvent.

How often should I clean my DPF? It is recommended to clean your filter every 30,000 to 50,000 km. However, this can vary depending on your driving habits. If you do a lot of short trips, for example, the filter will clog up more quickly.

Dies and symptoms of a clogged DPF

Neglecting this can lead to more serious problems, such as engine damage. The price of cleaning a DPF can vary depending on the method you choose and the condition of your filter.
3. How to choose the right additive for DPF cleaning?
4. If you perform the cleaning yourself with this product kit, it will cost you less than going to your garage or dealership to have it decarbonized. Indeed, the additive products you find on the market are inexpensive. You can choose between different types of additives, depending on your needs, the condition of your filter, and the price.

Foaming additive: This is used to clean light filter clogs. Simply pour it into the fuel tank and let it work while you drive.

Gel additive: This is more effective than a foaming additive because it adheres better to the filter. It is also used by pouring it into the fuel tank.

Powder additive: This is the most effective but also the most corrosive. Therefore, it is important to check that it is compatible with your car before using it.
