Are you familiar with DPF cleaning? If you want to avoid unnecessary diesel engine repair in Inverness, this must be a part of your regular maintenance regimen. But what is the proper method and frequency of these cleanings?

Here are some FAQs to read from your dependable auto repair shop in Inverness, the IT Garage, to guide your DPF cleaning procedures.

What is a DPF?

DPF stands for “diesel particulate filters.” These parts are instrumental in cleaning the exhaust that diesel engines emit. A vehicle’s exhaust filters through this piece of equipment through an open end and out through a plugged end. Up to 90 percent of the harmful particulates in the exhaust get trapped inside the DPF.

Why does a DPF get dirty?

A DPF otherwise known as a Diesel Particulate Filter is located within the exhaust system usually near the Catalytic Converter.

The DPF is responsible for removing diesel particulate matter (soot) from the exhaust gasses of a diesel engine vehicle.

Short trips with a lot of stop and starts is the biggest cause of DPF’s becoming blocked, along with the poor quality of diesel, it doesn’t take long to block a DPF.

In order to clean the DPF, which is continuously accumulating soot, carbon deposits need to be burnt off, this is done by raising the temperature of the exhaust gas at the inlet of the filter.

During regeneration the exhaust gas temperature is regulated precisely by the ECU.

To prevent a DPF from getting clogged or dirty which constantly makes the engine run rough, it must be regenerated regularly. This is done by burning off the soot that has accumulated inside the filter.

Different Types of Regeneration

Passive Regeneration is a process whereas the soot particles are steadily burnt off without the intervention of the ECU. This occurs when you are traveling at highway speeds and usually around 3000 RPM. The temperature of the exhaust gas will reach around 660 degrees Celsius.

Active Regeneration is where exhaust gas doesn’t reach temperature for Passive Regeneration, consequently, soot particles are not eliminated and instead accumulate inside the DPF.

When the DPF is clogged a threshold of 18 grams is reached and the ECU will do an Active Regeneration.

Why should I keep the DPF clean?

Properly maintaining the DPF is important for several reasons. When you keep the DPF clean, you will benefit in multiple ways:

  •  Compliance: Federal mandates regulate the operation of diesel fleets to help protect the air we breathe. Keeping the DPF clean will keep you in compliance with these regulations.
  • Operation: If the DPF is not cleaned, debris will build up, and your vehicle will suffer. You will experience filter damage, engine damage and reduced power.
  • Performance: While poor DPF maintenance causes serious issues with your vehicle, proper cleaning will enhance its performance. You will experience better fuel economy, better engine performance, longer-lasting DPFs and fewer trips to your auto repair shop in Inverness.

How often should I clean the DPF?

This answer varies by vehicle and oil type. Most should be cleaned between 200,000 and 300,000 miles. Experts recommend following the manufacturer recommendations for frequency of cleaning. Don’t wait for dash indicators to tell you it’s time. Be more proactive and watch for warning signs that the DPF needs to be cleaned. These include loss of power and decreases in fuel economy. Additionally, vehicles that spend more time idling typically need DPF cleaning sooner than others. The amount of oil the rig consumes, and the number of engine hours are also important factors. So, when you see your mileage coming to these points, be sure to check them in to your trusted car servicing shop in Inverness like the IT Garage.

How should I clean the DPF?

The methods for cleaning the DPF include heat, compressed air and a combination of the two. Cleaning should be completed by a trusted auto mechanic at a registered auto servicing shop in Inverness such as the IT Garage.
