Many diesel owners believe their vehicles would be better off without the Diesel Particulate filter but are they right? In order to meet new emissions standards, the DPF was introduced in 2007 as a way to lower the amount of soot and ash being exhausted from diesel vehicles. The engines were generating the same particulate output but now those emissions were being contained and neutralized instead of escaping into the atmosphere.
Banks Special Projects Lead Erik Reider shows us how the DPF works by breaking down diesel combustion, diesel exhaust, and the process of regeneration (regen). Erik shows how to get the most out of your vehicle and DPF by using high-quality oil and tuning cleanly.

A clean tune increases power without increasing emissions and therefore does not over-tax the emissions systems including the DPF. As manufacturers improve modern turbo diesels, the engines produce less in-cylinder emissions which means the after-treatment systems like the DPF, the DOC, and the SCR can be made less restrictive. Understanding how the DPF and regens work is a major part of tuning diesel engines safely and keeping the emissions system functioning properly.
