What Happens During An Emission Delete - DPF/EGR Dry Run

all right hi everybody ryan here again so i've had some requests about um egr and dpf deletes uh so i'm just going to kind of do a run through and this is not all inclusive um it can be different with different engines but it's just kind of what i know what goes through um what the process is with the typically with most uh deletes so kind of jump right into it so egr this is the egr valve on this cummins is x15 right here this little unit right here the valves right there so that's what kind of controls the flow of the exhaust gas back over on the other side to the intake manifold so typically all this stuff they gotten these systems pretty incognito i mean the deletes incognito to where everything's still in place and like the the untrained eye if you're looking at it you wouldn't even know anything hasn't been done it's like you're not you're not taking all this stuff off now while everything is still be the wiring harnesses sensors everything will still be here usually this will be shut down the cgr valve will be shut down with the software basically so where it'll just be closed then so as we kind of move back around that exhaust gas goes through down around to the egr cooler which moves back up into the end of the exhaust manifold so in a lot of systems or deletes they'll actually put a blocking plate of some sort in there and that will keep the exhaust from actually it'll block off the egr cooler essentially and it's not nothing's even going through it because that with that exhaust pressure if you are still getting exhaust pressure through there it can eventually run down down the road you can see because there's there's tubes through that and there's coolant running through there to cool that exhaust gas before it goes into the engine back into the intake because you want cooler air you know to get better fuel economy with cooler air is uh is more dense so you can pack more air in so better fuel economy more power and all that good stuff so throwing hot air in isn't good like i said so you got a mixture or a basically like a radiator in there inside that egr cooler to where it's cooling the exhaust gas coming out here and you know as you know exhaust gas can reach temperatures if you've got a pyrometer you can you know be a thousand degrees so you don't want thousand degree exhaust gas coming into your engine so it's um i i don't like the whole idea but you know it is what it is i think it's stupid but uh you know throwing exhausts back into an engine and trying to reburn it on top of that you got up to 1000 degree exhaust gas that you're putting in so it's it just is what it is so so that's kind of um the egr portion of this i mean like i said a lot of this stuff is software um so when when it's programmed it's gonna shut this off it's gonna change if you get a variable geometry turbo like this that could change some of the parameters within that and like i said in and some deletes they physically block off the egr cooler as well so so that's the egr portion now the dpf portion um i'm not going to take all this apart so i'm just doing like a quick run through so if you guys have watched my dpf canister replacement if you want to see all this stuff we'll put a link in the video if you kind of want to look at what's inside of that my dpf and scr is underneath these steps two big canisters the dpf is the main one it's got that ceramic honeycomb in it so if you're doing a dpf delete again mostly software it's going to shut all that stuff off it's not going to do regions it's going to your your diesel doser injector here right off the turbo it's going to shut that off but like i said there's no reason it's still going to be here but it's just not going to do anything it's not going to inject any fuel like i said you waste a lot of fuel with this guy this is actually the fuel line this is the coolant line to cool that so this is uh yeah fuel here to where it injects fuel in to heat that up to that catalyst section of the dpf it heats that up to a little over 930 degrees or so to actually start that reaction to burn the carbon off so um and this has to be like 500 and this inlet exhaust temperature has to be like 570 degrees roughly to start that whole process so you waste a lot of fuel with that dumping fuel into your exhaust to start that reaction to burn all that stuff but if you're doing a dpf delete like i said again software it's going to change a lot of parameters in the turbo and and some people run the problems to where you actually um you can burn your turbo up so again um a lot of with these deletes a lot of people running the problems with the turbo when you change the parameters it's not uh the back pressure and all that and the way the the flow and the heat that's where people run into a lot of problems with uh if you get a bad tune you can melt this turbo down and i bought this is a newer turbo aftermarket with the actuator you're in about five grand that's putting on yourself i mean if you go to cummins just with the parts and the actuator and calibration of the actuator you could be looking uh closer to nine to ten thousand dollars on this particular engine um with a delete i mean there are some other i've heard some guys saying put a series 60 detroit turbo on there i don't know how that would all work out but uh with with this specific turbo variable geometry turbo which i like variable geometry turbos because it kind of it changes the aspect ratio of the the fins within the turbo or the turbine for the conditions you know what you're running at as far as what the needs for boost and all that so i like a very variable geometry turbo um so i wouldn't i don't think i'd be a big fan of throwing you know a non-variable geometry type of turbo in it like a series a standard series 60 turbo or something like that off of detroit so um so that's where a lot of people run into problems is with once you change those parameters if they don't know what they're doing or if it's a bad program or tune you can you can this turbo get too hot then to melt it down burn the bearings up or whatever and it's going to come apart so and then you take a risk of if you burn up these bearings you know you got oil pressure here it can start pumping that oil into the intake and then it's it's like it can the engine can actually run away which i've seen a video of an engine running away where actually the flywheel like went through a brick wall when the engine when they hit like 20 000 rpm and came apart so same thing with like natural gas engines or any any type of engine if there's a natural gas leak on the gasoline or something it can suck that gas in and just run you know very high rpms until the engine comes apart so so that's kind of my spiel on tunes and turbos as far as let me get back to the dpf and uh scr so if you're going to do a delete on dpf like i said watch that other video we have where we did the canister change out you can kind of see the internals that that honeycomb ceramic deal that's all going to have to be drilled out you're going to drill about a four inch hole through that or bust all that ceramic stuff out so that actually the exhaust can flow through it and it's not getting plugged up as it used to be with the filter so you're gonna knock a big hole in that so that you know if you're pretty much once you knock that hole in that for that canister there's no going back it's ruined i mean or it's not technically ruined but you could never use it as it was again so you might be if you're kind of wanting to do this and you might want to go back at some point you might be better off to try to find a used canister or something or an old a bad one that you can bust the ceramic out of and and put that in so but after that dear the def lines and all that df pump df doser down there and all that def injector whatever you want to call it all that stuff's going to be shut off as it's not going to work anymore it's all going to be there but it's just not going to do anything so that's pretty much it so i mean that that whole canister and all that it's just going to be straight through because you're going to put a hole in it or drill through it that ceramic and that's pretty much it like i said a lot of it's mostly software um as far as harder like i said uh the the dpf canister you got to put a hole through that depending on the kit or the tune you get you may block off the egr cooler but other than that it will the software is going to shut that egr valve off to where it's not sending that exhaust gas over and uh that's pretty much it so i hope that kind of that's just kind of a down and dirty you know kind of vague type of description um you know it's there's different for different engine models and all that and different tunes or whoever you're getting it through could be different so it really depends but that's kind of as far as what i know that's kind of what goes down with these deletes so so i hope that helps you out uh if if that's what you're looking at the information you're looking for would be trying to join the best i can uh so again uh you guys always know we're doing the landstar stuff owner operator stuff truck maintenance stuff we're kind of going into another business here with uh getting into an on-site service maintenance business kind of moving into and maybe looking into being like more of a fleet type owner type thing with uh putting somebody in this truck and maybe buying some other trucks in the future so it's kind of what we got going on here so uh if you haven't subscribed subscribe please hit the bell for the updates like the video give us a thumbs up and if you're interested in the farm and stuff you know we kind of sweat the channels you can check out the other channel as well if you like that type of stuff we got a lot of stuff going on there now that the weather is getting better and all that so check that out as well so again thanks for watching we appreciate the views and the support and we'll see you next time you
