Understanding the Most Hated part of your Truck | Banks Entry Level

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.

With tighter emissions standards and stricter enforcement, the DPF and the rest emissions systems seem to be the only way to keep diesel trucks from being regulated out of existence. Will manufacturers come up with a better simpler way to reduce emissions? Or is the DPF here to stay? What do you think?

[BigKandRtv]

It's crazy that the highest quality videos on diesels are by an after-market support company. Banks, keep it up!

Great video! I am a retired mechanic (ASE Master Tech) and I live in Northern California. I had a CA Smog (test and repair) smog license for over 30 years. Banks is a world apart from all the so called "experts" out there. Understanding how these systems work and designing components that work with and even improve the performance of these modern emissions systems is key. Gale Banks and his employees are a class act really know what they are talking about.

Coming up on 100k miles running the Derringer on my L5P. Reliable and powerful, I couldn’t ask for more. Thanks for the great product!

[hansberggren]

We shall now show you why you shouldn’t cut out your emissions equipment by cutting apart this emissions equipment that we got from… well never mind that part…

In all seriousness thank you for explaining all of this. I have asked 3 performance shops and 2 EPA agents how all of this garbage helps the environment. You are the only people who’ve been able to speak to it intelligently so THANK YOU!

[GuretoSefirosu]

I don't believe that a majority of people delete for power. It's reliability. EGR systems clog intakes and ruin engines WAY before the rest is worn out. The DPF can clog and not burn completely (think city driving with multiple stops) and ruin the engine as well. On top of that, when these parts that are forced upon us fail, the government won't be there to replace them and it's insanely expensive to replace them. It's far more financially viable to remove the components when they fail rather than replace them. God forbid your engine is fried due to a clogged DPF, those things are over $10, 000, which is the cost of a small commuter car.

I see regens almost every tank. My truck is 100% bone stock. Reliability concerns drive my desire to remove the crap, but I have not done so, yet.

[mikerider]

Great video. Although DPF and SCR technology has came such a long way producing less emissions and record power/tq, when they need replaced, parts availability and costs are crushing. Trucks sitting for extended periods at dealers waiting for parts can really put a business owner who relies on it for a living in a real bad spot. Thats when the systems are removed- wait to follow the rules or put food on the table and keep the business open. Banks understands diesels better than anyone but when this emissions technology fails, the consumer is left to wait and pay up or remove it. The government is the king of "Do as I say not as I do". The blatant disregard of EPA rules by military vehicles, ships, planes etc etc. makes me scratch my head. If costs to repair and maintain diesel emission systems were reasonable and readily available when repairs are needed, I believe there would be far less deleted late model trucks out there.

[rodgraff]

Erik, s explanation sounds like it’s coming from a very accomplished teacher. Give this guy a raise, and keep him around. Coming from a service engineer who taught 30 years.

[frankclark]

My 2017 Superduty has 300, 000 miles. Zero issues with the Egr or DPF. Been running the derringer and Amsoil for 200k miles. I’m living proof this works.

[craighoffman]

Really informative and well produced video. Eric is excellent!

DEF vs. EGR use is the tightrope manufacturers have to walk while meeting emissions targets. Heavy EGR use to lower NOx creates more soot which taxes the DPF. Lighter EGR use runs hotter and cleaner soot wise, but requires more DEF to deal with the resulting NOX increase while meeting emissions targets. Less EGR is generally good for the DPF and overall emissions system reliability.

It is reported by owners that GM's new 3 liter I6 diesel uses quite a bit of DEF. I wager GM is running lower levels of EGR in that engine, and the EGR it does run is filtered through the closely mounted DPF first. Recently saw a teardown video of the new 3.0 on the "I do Cars" YT channel, the engine was quite clean inside, looking more like a gas engine and not looking like a 145K mile diesel at all. Alas, that particular engine got chewed up as the idiot owner didn't keep oil in it and the pressure fed cam chain tensioners lost the plot, as did the main bearings if memory serves.

Though much maligned for it's belt driven oil pump, GM's 3.0 I6 diesel is a cool engine, and the apparently by design increased DEF use is worth it. The belt looked fine in the YouTuber's teardown video by the way. GM's problematic by the 150K mile mark torque converter will probably need replacing anyway, the belt is easy to service at that point 😆

The biggest issue i have with the emissions system is that it is extremely unreliable and is consistently the cause of down time and in the trucking industry, that costs you more than the repair itself generally

[TheStickinator]

Makes me appreciate my 7.3 all the more.

[extremerc]

Cool technology, it’s a shame the epa mandated the 250 mile limp mode fault. Unfortunately that’s not practical for my use, I ended up deleting after being stranded.

[jeradbennett]

I've always thought that the focus should have been on fuel efficiency standards instead of emissions. If modern diesels were allowed to run uncorked but tuned for maximum efficiency imagine the fuel economy numbers we would be seeing these days. And it almost goes without saying that if you're burning far less fuel your emissions output would be much lower as well. The fuel economy numbers on modern diesel pickups are pretty terrible and we've actually gone backwards in most cases. I salute Banks for doing what they have to do to stay in business and push the tech development envelope with their products. That being said, the folks that I know with deleted trucks have seen substantial fuel economy increases and overall reliability improvements.

[kurtbyars]

My first good diesel truck was stock and I contacted Gale Banks Engineering about how to do something to help the fuel mileage and performance meaning torque for towing REALLY heavy loads they talked with me anytime I wanted and finally my changes were made very few actually and the thing doubled in mileage and torque. It was over the warranty and had RIDICULOUS TORQUE AND FUEL MILEAGE and I can't say enough for their help ! And no charge for telling me what's best for that particular truck ! When my new truck warranty is up I'll be doing this ay with their direction of course !!!! We're talking EXPERTS. THANKS GUYS

[Thomas-cktm]

thanks for video, gave a really great explanation about the system.. some old timers complain about all the new emission standards but I remember a time when you didn't want to be driving behind a big rig or sitting beside them on the road because of all the pollution coming out of their exhaust..and the truck stops were like a bad industrial park

[BlackenedBrew]

Fantastic video! I've always wondered why the #1 guy in trucks (Gale Banks) is trying to work with the emissions systems instead of fighting them. Sure, money talks, but with as educated as he is on the subject, he has to know something we don't. Please keep these videos coming!

[d.williams]

Excellent video! My personal goal is to buy a taken care of pre emissions diesel truck and never have to worry about emissions checks and the issues that come with emissions equipment. Honestly if manufacturers would just warranty emissions equipment my faith would be restored. I wasn’t able to enjoy any road trips with my DPF equipped truck because I couldn’t stop thinking about it failing in the middle of nowhere and being stranded because a particulate sensor went out.

[thewanderlywagon]

Congratulations to Eric for his outstanding presentation on DOF, DOC, and SCR in the field of chemical and mechanical engineering! It’s impressive to deliver such a comprehensive overview you have earned your PhD. Eric’s expertise and excellent delivery certainly deserve applause. Well done, Eric! Now, I can’t wait to order ALL Banks products for my 2020 Ram 3500 just need to wait for warranty to end.

[DanSpeerRacing]

Just wanted to say I'm loving this series. You guys are breaking information down to clear, easy to understand bits that are explained clearly for people of every level of knowledge to understand without being boring or condescending. Great job, and I look forward to the next installment!
