The particle filter is a fairly new invention that aims to remove harmful particles from the exhaust gases of latest diesels. It has long been discovered as the miracle solution to these pollution complications. However, it doesn’t work as well as expected and triggers more complications than it solves, which is why we will see in this article when changing the particulate filter of a Renault Megane? . To get this done, to begin with, we will find out what the particle filter on your car is intended for, and then when to replace the particle filter on your Renault Megane.
What’s the point of a Renault Megane’s particulate filter?
So we start our article with the reason to do this element not too long ago built in into diesel automobiles. As we mentioned briefly in the introduction, the intent of this filter was to fix the complications of pollution and harmfulness of exhaust gases from Renault Megane automobiles. Its operating principle is to store exhaust gases that are unburned or that still contain harmful particles, and when it is at a adequately high temperature to trigger a second combustion that will finish burning and get rid of all these carcinogenic particles. Unfortunately, to reach this very high engine temperature, you have to be on the highway or have your Renault Megane engine revving up. So we have noticed with time that cars that are principally on short trips or in the city do not allow the particulate filter to burn these gases and we will observe in the next part that these complications can force you to replace the particulate filter of your Renault Megane .

The second one, the one we are enthusiastic about today, 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. However, as described above, it necessitates 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.
