According to an analysis done by Science Direct in 2017, Diesel Particulate Filter (DPF) still remains one of the most crucial after treatment device that is meant to reduce the emission of particulate matter from diesel-fueled engines. According to the study, DPF is excellent when it comes to soot filtration, therefore, enabling environmental sustainability which consequently leads to avoidance of respiratory and heart-related diseases.
This should ring an alarm in your mind about the importance of DPF to both your relatives and close friends. A study shows that since 2009 a law was passed that all modern diesel vehicles have to be fitted with DPF. The aim of this law was to reduce particulate emission by 80%. But what really is Diesel Particulate Filter?
A DPF is a kind of filter that captures the exhaust soot and stores it so as to reduce particulate emissions from diesel engines. For the DPF to be regenerated, the soot has to be emptied severally or be burned off.
The regeneration process burns off soot that has been deposited excessively in the filter. This is the reason behind the reduction in the emission of the black smoke that identified diesel vehicles.
According to legislation on exhaust emission, it is illegal to remove diesel particulate filter from your car. You may face heavy fines and consequently the invalidation of your car insurance.
It is worth knowing that there are various problems that affect DPF. One, in particular, that is very common is the blockage.
How do you tell whether your DPF is having a blockage? Well. Depending on the manufacturers of your car, the basic signal that your DPF is clogging with soot is the appearance of an orange light on your dashboard. The light is in form of a piped box having dots at the center.
What really causes this blockage? One of the major reasons why you may have your exhaust pipe blocked is:
- Traveling short distances at very low speeds. This is the reason why some manufacturers usually recommend taxi drivers around the town to use petrol cars.
- Poorly done servicing, a well serviced DPF should last for 100,000 miles.
- Use the wrong type of oil engine. Some oil engines may contain additives that will automatically block your filter.
- Using low-quality diesel
- Doing modifications to your filter
- Constant use of low levels of fuel.
But how do you maintain your DPF despite blockages?
How to Maintain your DPF
Qualified manufacturers have advised that the best way of maintaining a DPF is making sure that it can regenerate itself fully when the soot has clogged the exhaust pipe. There is Passive and Active regeneration.
This occurs when the vehicle is at high speed for around 30-50 minutes. It raises temperatures of exhaust, therefore, burning off the soot.
This means that extra diesel is automatically injected so as to make the filter increase the exhaust temperature. It may not be effective for short journeys since the regeneration cycle may not be complete. Some of the signs of Active regeneration include:
- High fuel consumption
- Changing engine note
- Running cooling fans
- Acrid smell from the exhaust.
In conclusion, it is advisable that you repair your DPF if it develops some issues so as to avoid air pollution and diseases. Please look here for a full range of diesel particulate filter options.
