The particle filter is a fairly new technology that is designed to take out harmful particles from the exhaust gases of latest diesels. It has long been discovered as the miracle solution to these pollution problems. However, it doesn’t work as well as designed and causes more problems than it solves, which is why we will discover in this article when changing the particulate filter of a Ford Focus? . To get this done, first of all, we will find out what the particle filter on your motor vehicle is intended for, and then when to change the particle filter on your Ford Focus.

What’s the point of a Ford Focus’s particulate filter?

So we start our content page with the explanation for this element recently built in into diesel automobiles. As we outlined quickly in the introduction, the intent of this filter was to resolve the problems of pollution and harmfulness of exhaust gases from Ford Focus 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 cause 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 Ford Focus engine revving up. So we have realized over time that cars that are specifically on short trips or in the city do not enable the particulate filter to burn these gases and we will see in the next part that these problems can force you to change the particulate filter of your Ford Focus .

The second one, the one we are interested in today, works with precious metals that will produce a chemical reaction at high temperature and cause the regeneration of the filter and the evacuation of the carcinogenic materials. However, as described above, it requires 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.
