What is DPF soot load?
Radio frequency (RF)—The DPF load is calculated based on the absorption of a microwave signal by soot accumulated in the filter. Accumulating electrode—A DPF failure is detected by measuring a change of electrical properties of an electrode due to a time-dependent soot deposition.
How do I fix my Diesel Particulate filter warning?
If you get a warning light showing that the filter’s blocked, it should be possible to complete an active regeneration cycle and clear the warning light by driving for 10 minutes or so at speeds over 40mph.
How can I check the level of soot in my DPF?
The level of soot calculated from the DPFE sensor can be reviewed by using diagnostic equipment and viewing the live data (either in digital of graphing modes) in Snap-on’s diagnostic platforms. There are three different regeneration modes used to clear the soot stored in the DPF:
Why is the diesel particulate filter a ticking time bomb?
The Diesel Particulate Filter (DPF) is best described as the “ticking time bomb” in most modern diesels. Similar to EGR problems, the DPF can become clogged up from city driving where the car does not get up to temperature. The whole reason the Diesel Particulate Filter came along was to clean up the diesel car image (Euro 5 Emissions, 2009).
Are there any problems with the diesel particulate filter?
DPF Problems, Symptoms and Fixes. The Diesel Particulate Filter (DPF) is best described as the “ticking time bomb” in most modern diesels. Similar to EGR problems, the DPF can become clogged up from city driving where the car does not get up to temperature.
What happens to diesel soot when it is burnt off?
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.
