A lot of people have opted for the removal of the diesel particulate filter (DPF) as DPF is prone to extensive damage due to clogging which can result in a four figure repair bill. However, governments have put in strict regulations regarding DPF removal as it is harmful to the environment. So the question is whether you should go for DPF removal not? Before delving further into that matter, let us take a look at what DPF actually does.
Auto mobile engines emit numerous harmful particles which cause damage to the environment. These minute particles are captured by DPF, which is located inside the exhaust system, preventing them from being expelled into the atmosphere. There comes a time when the filter needs to be cleaned and replaced. The filters are cleaned automatically through a process called regeneration which burns up the soot particles collected in the filter. Most cars are fitted with a DPF in order to reduce the amount of particulates being emitted. Regeneration is carried out automatically in such engines whenever the car is driven at constant speed for about 15 minutes.
Newer cars are fitted with better DPF which can burn off soot faster and more efficiently. However, even they have a shelf life and the filters need to be cleaned or replaced after a certain mileage, which ranges anywhere between 80,000 to 150,000 miles.
The public have been annoyed by the decision taken by governments to make DPF removal illegal as the costs involved in replacing or cleaning up a DPF can be on the higher side. Governments though have taken the correct decision as it is necessary to keep a check on the amount of air polluting particulates emitted by a vehicle.
DPF has been a standard feature in most of the diesel powered cars as they are the ones which tend to release more number of particulate matter into the air. Thus, people who drive diesel powered cars have been the ones to be affected most by the recent changes in laws regarding DPF. People are concerned about buying diesel powered cars as it may lead to them spending extra money frequently for cleaning the DPF, which can get clogged quite often if not cleaned properly from time to time.
Should You Buy A Diesel Car?
It is very important for people to realise the fact that it is everyone’s responsibility to take care of the environment in which we live. Air pollution due to particulate matter indirectly harms all of us. The fact that a DPF can be cleaned automatically if one drives a vehicle at constant speed for a short while should be taken into consideration. People should not make their decision based on the cost involved in cleaning a DPF.
There are new technologies which are being developed for cleaning the DPF at a lesser cost. So it is advisable not to opt for DPF removal as if car fails to meet the emission standards and guidelines, it will be deemed as illegal for road use. If all of this still looks like a liability, a petrol engine powered car is the best solution.
