In this video we tackle the #1 Problem on DEF and DPF Systems and offer some secrets and solutions on getting these problems fixed! There are many problems with these systems, but this seems to be the most common and solves the most issues. This is not a technical video explaining the intricacies of the exhaust filter system, it is explained in laymen's terms. Were down to $100 for DEF injector, plus labor, on an install at our shop in Houston

The DEF Doser does not effect the temperature during an active regeneration. It is used only to combat Nitrogen Oxide in the SCR and is mounted after the DPF Filter downstream. The truck uses the turbo actuator, 7th injector, and DOC to heat up to spec.

@TruxasSales 2 жыл бұрын

The DEF fluid does actually create heat in the SCR. The reaction that occurs and changes the gases is an "exothermic reaction" and creates heat. And if is sprays to much fluid or dribbles the fluid out it can cool the SCR and cause "ammonia slip." The SCR can also get dirty and clogged as well as the DPF filter. If the Doser is not spraying properly the system can abort the cleaning/heating. We made this video in layman terms and it isn't a video teaching about how the SCR and DPF work. "...NOx reduction with ammonia is exothermic, resulting in the release of heat." www.epa.gov/sites/default/files/2017-12/documents/scrcostmanualchapter7thedition_2016revisions2017.pdf

@gcmd5852 Жыл бұрын

The DOC creates heat to bring the SCR up to temperature then when the SCR is hot enough ( approximately 400 degrees ) the def gets injected into the SCR and turns into ammonia.

I have a 2016Cascadia and had constant def issues and shop changed nox sensors and def pump dpf filters dozer valve and still kept having issues costing me thousands of dollars. Then I came across a video about the def metering valve and while it was expensive like you were saying right away on first regen I noticed the difference in regen temp in the first 5 to 10 min the codes popped back up and 5 min later were gone after cycle ran codes check again codes were cleared and gone. Freightliner kept telling me my one box needed replaced. Saving me from a ten thousand dollar job.

eBay, but you may have to wait 2 months to get them at that price, we have them right now for $30. I'll see about the video. it's pretty easy to change but if you don't do it right the dowser doesn't work property and you have to take it all apart again and you may have engine codes that need to be cleared. sometimes the extra money for the whole dowser is worth the less potential headaches.
