The particle filter is a fairly modern technology that aims to take out harmful particles from the exhaust gases of modern diesels. It has long been seen as the miracle solution to these pollution problems.

Its operating concept is to store exhaust fumes that are unburned or that still contain harmful particles, and when it is at a adequately high temperature to cause a second combustion that will finish burning and get rid of all these carcinogenic particles. Unfortunately, to reach this very high engine unit temperature, you have to be on the highway or have your Renault Kadjar engine unit revving up.

The second one, the one we are keen on today, functions with precious metals that will create a chemical reaction at high temperature and cause the regeneration of the filter and the evacuation of the carcinogenic materials.
