DPF or diesel particulate filter are components that extract diesel particulates physically to prevent them from being released in the atmosphere. They are designed to wipe off the soot that is generated by the diesel engines and control emissions. Because of the limited capacity of the DPF, the collected soot has to be disposed of or ‘burned’ from time to time to revive the DPF. With continuous inventions and modification, DPF has become the most efficient technology for regulating the emissions or soot.
Unfortunately, most of us are unaware of maintaining this part of the vehicle, which is imperative to save ourselves from spending a hefty amount on its repair and maintenance in the future.
WHY IS MAINTAINING THE DPF IMPORTANT?
Diesel particulate filters keep the released emissions in sync with the other parts of the car and prevent the poisonous particles from being released in the atmosphere, thus preventing the hazards caused due to air pollution. If the DPF has collected a lot of particulates, it becomes clogged and won’t work properly. Malfunctioning of DPF may lead to decreased fuel efficiency, engine and filter damage, all of which eventually lead to poor performance of the car. It, therefore, becomes very important to keep a check on the filters regularly rather than facing bigger issues in the future.
Here is a list of some facts which give you more reasons to look out for a properly functioning filter.
Increased fuel efficiency
Saves the trouble of replacement
Higher resale value
Prolonged engine warranty
WHY A CHOKED DPF?
Whenever there is congestion in the diesel particulate filter, a warning light will pop up, informing you about the same. A blockage usually happens because of driving short distances at a low speed. The set standard of the distance a car should cover before going for a replacement is 160,000km.
PROCESS OF REGENERATING A DPF
The process of regenerating a DPF is a procedure that involves cleaning the filters to dump the soot that is collected from the engine because else, the filter becomes jammed and the vehicle won’t function properly.
There are two ways in which DPF can be rejuvenated or regenerated- passive and active regeneration.
Passive regeneration takes place when the vehicle is running on the road for a period of nearly half an hour, without the driver knowing it. The time span of 30 mins permits the exhaust to settle at the right temperature and burn off the particulates.
Active regeneration is mainly meant for drivers that are on the road for shorter distances and thereby don’t reach the limit for passive regeneration and may still have burnt soot in the DPF. Once the filter reaches a certain limit while the vehicle is being driven and the fuel is fed into the engine, the exhaust temperature rises, and the particulates burn off. Active regeneration needs a time span of around 15 minutes with the vehicle moving at a speed of about 60km/h.
