The Exhaust After-Treatment System uses a filter called the Diesel Particulate Filter (DPF). As the name suggests, the Diesel Particulate Filter’s job is to trap the particulate matter from the exhaust gases. Since this trapping increases the exhaust back pressure on the engine, the filter needs to be regenerated periodically to burn off the soot accumulated in it. This is done by increasing the exhaust gas temperature and maintaining oxygen in the exhaust. thereby meeting the required PM levels, as per BSVI emission norms before they are released into the environment.
To understand the working of any filter, the ‘tea strainer’ which everyone uses to pour a refreshing cup of tea is the best example! You might use the same strainer multiple times but beyond 2-3 pours, its pores get clogged and need to be cleaned thoroughly so that it can perform its function again. Similarly, any filter used in your vehicle needs to be regularly cleaned, regardless of what it is designed to trap so that it can continue to perform its function effectively.
Since DPF is also a filter, it has a finite capacity to store soot. And when this accumulation goes beyond a limit, it can start impeding with the flow of exhaust gases. This can lead to higher exhaust back pressure which will cause risk of unnecessary wear on your vehicle’s engine. It will also impact the emission levels. Hence, the DPF is designed to need regular maintenance and cleaning through a process called Regeneration.
During the process of Regeneration, the soot is burned away with high temperature in the Diesel Particulate Filter (DPF). Regeneration is normally performed automatically while driving but in certain driving conditions where required temperature cannot be achieved, it has to be initiated manually.
Automatic regeneration happens during driving when the load on engine is high enough to reach a sufficiently high temperature.
When you drive continuously for several hours at low engine load or continuously run at idling speed or frequently start or stop due to traffic congestion or cover short trips in the city frequently, regeneration is not initiated automatically. It may be necessary for you to start regeneration manually in these cases.
There’s no such thing as a good time for downtime, especially when it is unexpected. Regeneration or Manual Regeneration.
A warning light on the cluster will alert the driver that the filter is blocked and regeneration needs to be performed manually. Manual Regeneration can be started by parking vehicle in a hazard-free zone with all safety precautions and instructions.
Designed to restore and maintain your vehicle’s performance. We provide expert cleaning, regeneration, and repair services to remove soot and blockages, ensuring your diesel particulate filter operates efficiently, reduces emissions, and complies with environmental standards.
