The particle filter is a quite modern invention that is designed to remove harmful particles from the exhaust gases of modern diesels. It has long been discovered as the miracle solution to these pollution complications. However, it doesn’t work as well as intended and causes more complications than it handles, which is why we will discover in this article when changing the particulate filter of a Toyota Rav 4? . To do this, first of all, we will identify what the particle filter on your motor vehicle is utilized for, and then when to change the particle filter on your Toyota Rav 4.
What’s the point of a Toyota Rav 4’s particulate filter?
So we commence our article with the rationale for this element not too long ago integrated into diesel automobiles. As we outlined quickly in the introduction, the goal of this filter was to solve the complications of pollution and harmfulness of exhaust gases from Toyota Rav 4 automobiles. Its functioning concept is to store exhaust gases 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. Sadly, to reach this very high engine temperature, you have to be on the highway or have your Toyota Rav 4 engine revving up. So we have realized as time passes that vehicles that are specifically on short trips or in the city do not allow the particulate filter to burn these gases and we will see in the next part that these complications can force you to change the particulate filter of your Toyota Rav 4 .

The second one, the one we are keen on 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 described earlier, 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. If you need to clean the EGR valve of your Toyota Rav 4 because of your particulate filter, do not hesitate to look at our article on this subject to identify what the process is.

In spite of everything, the current particulate filter have not been well designed and remain problematic, it is considered that because of the lack of a sufficiently regular temperature rise and other design complications, you should begin planning to change your particulate filter from 200, 000km if you have a use of your XX that is more urban and a little more if it is mixed .
