So we commence our content with the reason for this element not too long ago integrated into diesel vehicles. As we described quickly in the introduction, the intent of this filter was to fix the complications of pollution and harmfulness of exhaust fumes from Infiniti QX50 vehicles. 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 bring about a second combustion that will finish burning and get rid of all these carcinogenic particles.
