The particle filter is a quite modern invention that aims to remove harmful particles from the exhaust gases of modern diesels. It has long been discovered as the miracle solution to these pollution problems.

Its operating principle is to store exhaust fumes that are unburned or that still contain harmful particles, and when it is at a sufficiently high temperature to cause a second combustion that will finish burning and get rid of all these carcinogenic particles.

The second one, the one we are enthusiastic about today, functions with precious metals that will generate a chemical reaction at high temperature and cause the regeneration of the filter and the evacuation of the carcinogenic materials. However, as explained above, it needs very high temperatures, if these are not reached the filter will clog. If the filter is not regenerated manually, drive at high speed for about 20 minutes to reach this temperature and thus regenerate your filter, you will clog it and risk damaging your turbo, your EGR valve or your engine unit.
