Probably all of us have come across some frightening data provided by the World Health Organization. According to the statistics of the WHO from 2016 global air pollution caused an estimated 4.2 million premature deaths worldwide. The cause of these deaths was the exposure to ambient pollution from particulate matter higher than the average of 2.5 micrometers. Exposure to particulate matter may lead to serious health problems such as cardiovascular and respiratory diseases and even cancer. But what does this all have to do with DPF?
Today every modern Diesel car has a so-called Diesel Particulate Filter as part of its standard and mandatory equipment. Basically, the job of the DPF is to filter out the soot from the exhaust gases therewith preventing it from being released into the air that we breathe. In addition to the exhaust gas recirculation (EGR) and the catalytic converter, the DPF also serves a reliable and effective cleaning of emission gases.
In order to guarantee a proper and steady work of the DPF, it needs to undergo continuous regeneration.
However, this can only occur at an average temperature of 600 °C . Normally, an engine reaches this temperature when the car is running at full speed on long motorway journeys. In stop-and-go or city traffic, the engine reaches only about 400 °C of combustion temperature. As a result, the soot cannot be burned and clog the DPF filter eventually preventing it from doing its job. In the worst case, a clogged filter can lead to a significant decrease of engine performance.
What is the solution?
To prevent a DPF from blocking we actually recommend servicing it on a regular basis. But how do you know that a DPF needs to be serviced? The first visible sign a car will give you is a DPF light that will appear on your dashboard announcing that a complete clogging of DPF is about to happen.
Here are some symptoms that will not remain unnoticed by an attentive driver:
- Loss of engine power
- An increase in fuel consumption
- Noticeable increase of emissions
- The car is unable to reach its maximum speed
In this case it is recommended to give a special DPF regeneration additive directly to the fuel which significantly delays the clogging of the DPF.
How does it work?
The regeneration additive lowers the ignition temperature to 350 degrees allowing the soot to burn leading to a successful regeneration of the DPF. In countries with good fuel quality we recommend using the additive at every third tank filling for a clean and effective DPF. In countries with low fuel quality it is recommended to use this preventive measure at every tank filling.
Remember that a clogged DPF does not only endanger your car, but also your well-being. It´s an absolute must to take good care of it.
