How To Unblock My Dpf Filter

A diesel particulate filter or DPF is a device in your vehicle that helps to reduce the amount of harmful, toxic emissions released when you drive. 

The DPF works by trapping soot particles in the exhaust gas and preventing them from being expelled into the atmosphere through your tailpipe. The main things that make up this “soot” are unburnt fuel, residual ash, and other byproducts of combustion.

Soot is a major pollutant that contributes to smog, acid rain, and respiratory problems. The EPA estimated in 2004 that diesel engines were responsible for emitting about 43% of all the soot produced in the U.S.

if you wonder how you can clean your DPF, here’s a guide that’ll answer all of your questions.

What Is a Dpf Filter

A DPF is a diesel particulate filter. It is a device used to remove diesel particulate matter, or soot, from the exhaust of an internal combustion engine.

The DPF can become blocked over time, resulting in performance issues and reduced fuel economy. A clogged DPF may also lead to an increase in harmful emissions being released into the atmosphere.

How Does a Dpf Filter Work?

A DPF works by trapping diesel particulate matter (DPM) through three main stages: inertial impaction, gravitational settling, and diffusion. Inertial impaction separates coarse soot particles from the exhaust gases as they pass through a honeycomb-like structure.

This is usually achieved by passing the exhaust gases through several narrow passages. The smaller particles are forced to stay in the centre of the tubes, while the larger ones are pushed toward each outside wall of each tube.

The inertial impaction process gets rid of most coarse soot particles which make up most of the DPF’s capacity. However, it cannot remove fine soot particles.

These finer particles are usually small enough to pass out through the honeycomb cells and into the exhaust stream. However, as they move through the DPF will get collected at the bottom of each cell.

This is where gravitational settling comes in. The lighter particles are collected at the bottom of each cell and the heavier ones will remain near the top of the cell.

Finally, diffusion takes place as diffusion waves travel through the DPF and work to strip away these trapped particles from each other – this is where temperatures reach up to 1000 degrees Celsius. Over time, main wavefronts break down into smaller and smaller waves that become less effective at removing fine particles.

What Can Cause My Car to Have a Blocked up Dpf Filter

One of the biggest factors in a car’s performance is its DPF filter. This helps to reduce harmful emissions from cars so they can be more environmentally friendly. Because this filter traps dirt and grime, it tends to get blocked up over time.

You can fix this problem with your car by getting a Diesel Particle Filter Cleaning service. This is something you can have done at an auto shop, but it might be more expensive. You also might want to try to clean the filter yourself with some home remedies or solutions.

If you prefer cleaning on your own, we will discuss some methods in the following sections.

How Do I Unblock My Car’s Dpf Filter?

There are many ways to unblock your car’s dpf filter, but all methods share the same goal—to remove any debris that may be blocking the filter.

The most popular method is to use exhaust gas pressure, which you can buy for around $100 or rent for $20 from a local auto parts store.

The pressure pushes out any debris that may be blocking the filter. You can also use an engine cleaning solvent, also called dpf cleaner, to try and dissolve any sludge that may have built up.

Some more working methods to clean DPF:

Method 1: DPF Regeneration

In this method, you will run your car’s engine long enough to heat up the dpf filter so it can release any built-up carbon inside. Then you want to let the car sit for around 10 minutes so that all of the released debris could fall off or burn out.

Now you need to turn on your heater and wait until the temperature is around 120 degrees Fahrenheit.

After that, you need to turn the car’s engine on, let it idle for around 10 minutes, and then take your car out for a drive at speeds above 50 mph.

This will cause the filter to release all of the trapped carbon through your exhaust pipe.

However, there are some things you have to be aware of. For example, the high temperatures will damage your car’s engine so you need to avoid driving it until you see your dpf filter is clean.

Also, whenever the conditions allow it, you should always use your air conditioner instead of a heater to keep your engine cool.

Method 2: DPF Cleaning Solvent

This method involves treating the dpf filter with a dpf cleaning solution. The cleaning solvent breaks the carbon deposits up, resulting in their release through your car’s exhaust pipe.

However, the chemical used to dissolve the sludge is toxic, so ensure that you work in a well-ventilated area and wear gloves while using this method.

But there are other important things to consider. If you don’t know how to use dpf cleaning solvent, then it’s recommended that you ask for help from someone who has experience using this cleaning method.

Also, you will need to drive your car until the engine is hot enough before adding the cleaning solution; otherwise, the chemical won’t be able to dissolve the carbon deposits.

4 Reasons You Should Clean Your Air Filters Regularly

Now that you know how to clean your dpf filter, it’s time to consider the benefits of keeping all air filters clean. Here are four reasons why should keep them clean:

1) Maintaining air filters will allow your car to run smoothly as there won’t be any airflow issues due to a dirty air filter. You will also improve gas mileage as well as horsepower and torque to a certain extent.

2) You can help your engine run more efficiently by using a clean air filter. This will ensure that the engine doesn’t have to work extra hard to move air through a dirty air filter, resulting in reduced engine wear and tear.

3) When you regularly maintain air filters, it will also help to reduce the number of toxins that enter your car’s engine. Overall, this can improve the performance and fuel economy by a considerable amount.

4) The cleanest filter is one that is never used because it doesn’t get dirty in the first place! So be sure to change your air filter at recommended intervals.

Conclusion

With a clean dpf, you will have a cleaner car that provides better performance and fuel economy. Now that you know how to clean your dpf filter, always be sure to use these methods when needed. Apart from this make sure to keep an eye on faulty injector symptoms and if you find any then fix it as soon as possible.
