The Diesel Particulate Filter traps the harmful diesel gases that gets cleaned regularly by a process called DPF regeneration. Emissions from diesel cars are a concern worldwide. The collected diesel soot particles are burnt off at high temperatures, which results in an “ash-like” after product. After the regenerating of the DPF, it can now restart the cycle of collecting harmful exhaust gases again.
There are 3 different types of DPF regeneration, which are active, passive and forced.
Active DPF Regeneration reads the back pressure of the exhaust or soot load of the filter to determine when to begin the regeneration. Once initiated, the timing of the fuel injection will alter that will result in the exhaust temperature increasing to burn the soot particles. During an active DPF regeneration, you may notice the following:
Higher idle RPM/Speed
Cooling fan working harder
Poor fuel economy
Smells from exhaust
Engine note change
Passive DPF Regeneration
Passive will take place once the exhaust reaches optimum temperatures where the regeneration will automatically begin. The exhaust will reach these temperatures will occur mostly on prolonged highway driving. Manufacturers that use a passive form of regeneration typically install a oxidizing catalytic converter near the engine to increase the temperature.
Forced DPF Regeneration
Forced is where the Active regeneration could not occur that has resulted in the soot levels reaching 70% and above. The diesel car will enter limp mode and will require a diagnostic tool to force the regeneration. Its important that this is done as soon as possible because once the car reaches 85% soot level, the DPF will need to be removed and cleaned.
