Diesel particulate filter

Soot particles are collected in the diesel particulate filter and periodically burned away at high temperatures.

During the cleaning period of several minutes:

▷ The engine may temporarily run less smoothly.
▷ A somewhat higher engine speed may be necessary to achieve the accustomed performance.
▷ Noises and a slight amount of smoke may emerge from the exhaust, even for a short period after the engine is switched off.
