As we mentioned quickly in the introduction, the goal of this filter was to solve the problems of pollution and harmfulness of exhaust fumes from Opel Astra 5 vehicles. Its functioning concept is to store exhaust fumes that are unburned or that still contain harmful particles, and when it is at a sufficiently high temperature to trigger a second combustion that will finish burning and get rid of all these carcinogenic particles. Sadly, to reach this very high engine unit temperature, you have to be on the highway or have your Opel Astra 5 engine unit revving up.

The second one, the one we are interested in in this article, works with precious metals that will generate a chemical reaction at high temperature and trigger the regeneration of the filter and the evacuation of the carcinogenic materials. Nevertheless, as mentioned above, it necessitates very high temperatures, if these are not reached the filter will clog.
