Diesel particulate filters, or DPFs, are an important
component of modern diesel engines. They are designed to reduce the amount of
harmful particulate matter, or soot that is emitted into the air. However, over
time, these filters can become clogged or faulty, leading to a range of
problems with your vehicle.
One way to check whether your DPF is working properly is to
check your MOT history. The MOT test is
an annual test of vehicle safety, roadworthiness and emissions that all cars in
the UK must pass. By checking your MOT history, you can see whether your DPF
has been flagged as a problem in the past.
In this article, we'll take a closer look at what DPFs are,
how they work, and what can cause them to become faulty or clogged. We'll also
explore the importance of check MOT history
and what to do if you suspect there is a problem with your DPF.
What
is a Diesel Particulate Filter?
A Diesel Particulate Filter is an emissions control device
that is fitted to modern diesel engines. It is designed to capture and store
soot particles that are produced during the combustion process. By trapping
these particles, the DPF helps to reduce the amount of harmful particulate
matter that is released into the air.
How
Does a Diesel Particulate Filter Work?
A DPF works by trapping soot particles in a series of small
channels or honeycomb-like structures that are coated with a special material
that acts as a filter. As the exhaust gases pass through the DPF, the soot
particles become trapped in the filter, while the remaining gases are released
into the atmosphere.
Over time, the soot particles that are trapped in the filter
build up and begin to clog the channels. When this happens, the DPF needs to be
regenerated, which involves burning off the trapped particles to restore the
filter's efficiency.
What
Causes a Diesel Particulate Filter to Become Faulty or Clogged?
There are a number of factors that can cause a DPF to become
faulty or clogged. These include:
1.
Short
journeys - If you use your car for short journeys, the DPF may not have
a chance to regenerate properly, leading to a build-up of soot particles.
2.
Faulty
sensors - If the sensors that monitor the DPF's performance are
faulty, they may not be able to detect when the filter is becoming clogged.
3.
Low-quality
fuel - Using low-quality fuel can lead to a build-up of
contaminants in the filter, which can cause it to become clogged.
4.
Faulty
injectors - If the injectors are not working properly, they may not be
delivering fuel to the engine in the correct way, leading to incomplete
combustion and an increase in soot production.
5.
Driving
style - If you frequently drive in a way that produces more soot,
such as driving at high speeds or accelerating hard, this can increase the
likelihood of the DPF becoming clogged.
How
to Check Your MOT History?
Check MOT status is a
simple and easy way to see whether your DPF has been flagged as a problem in
the past. Here's how to do it:
1.
Go to the government's MOT history website.
2.
Enter your vehicle's registration number and the make
of your car.
3.
Click on the 'Search' button.
4.
You will be shown a list of all your previous MOT
tests.
5.
Look for any warnings or advisories related to the
DPF. If there are any, it may indicate that there is a problem with your DPF
that needs to be addressed.
