I'm out of it now but back in early '06 I owned a 3406E turned up to 550HP that was almost 10 years old. If I was going to keep trucking The time was now to buy new, so I sprung for a 379(last of THAT breed) with a C13. I got it just before Christmas , '97 with an '06 C13. No DPF , no EGR and DEF didn't come 'til 2010 so none of that either. The viva's that came with that however were too weak for the C13 because the oil pressure was too low, running about 20 psi when warm. (I had a very educated man tell me that that oil pump could float 3 C13 engines so wear was no issue) The only problems I had in ten years with the ACERT system was that the # 6 VIVA failed once, and the shop replaced both #'s 5 and 6. The guy that owns it now had that happen again but seems to happen because # 6 is the last one on the gallery for the oil. I made a lot of money with that truck with almost no down time.
ОтветитьF the EPA
ОтветитьNOX is nitrogen oxide, NOS is nitrous oxide.
ОтветитьI worked for a company that had a fleet of the infamous Cat Ct660 trucks.
13 and 15 liter , all they were was yellow painted Maxx 13 and 15.
I hated those engines, it was always something else, every single day, cracked aftercoolers, pitted cylinder liners, the pto shaft off the back of the head. Absolutely garbage engines. It's why I left heavy equipment.
We bought a 2008 f750 with a c7 acert, the engine tag list the hp as a 360. Pretty cool
ОтветитьI have 2009 century class with Cat C15 Acert engine.
so far 1.2 million km and still going like new.
not sure about all acert but I think they really good after 2008
Im glad i have a 2006. Kinda haha. Darn epa
ОтветитьAbolish the EPA
ОтветитьI owed a 2001 C-15 " 6NZ " best engine I ever had in over 30 years truck driving since 89. Wish I still had it. Thank you 👍
ОтветитьNoX is actually oxides of nitrogen
ОтветитьOutstanding explanation, sir. Definitely a better explanation than DPC modules give. I do, however, have one small correction-
NOx is representative of nitrogen oxides, not nitrous oxides. Nitrogen oxides are emissions, nitrous oxides belong in your drag car.
That is by far the best EGR system ever built in my opinion pulling exhaust after the DPF system it was brilliant
ОтветитьSounds like it's counterproductive me you're pulling easier to create less oxygen so the fuel doesn't burn a hundred percent because your dpf to get more ash in it which in return causes more down time and the toe because it dehydrates your engine down to 5%epa is stupid proper running engine that is tuned properly needs none of that equipment to pass emissions
ОтветитьHard head is like caterpillars 7th injector
ОтветитьBasically the exact opposite of what they were trying to do it caused nothing but problems and made the engine run like s*** which caused more nox and more co2 what Brainiac came up with the idea of putting concentrated Pig piss in there to get rid of the ash
ОтветитьSee this is why I hate California they're the cause of all of this maybe we should take all these woke nutjobs given California and fence it off and tell him you're on your own
ОтветитьI'll tell you what Hawaiian takeoff isx15 that has 500,000 miles on it the intake is half of what it was when it was brand new if they think that they're helping emissions by putting an EGR on a diesel engine they're badly mistaken they're causing a problem
ОтветитьI don't have a problem with you a certs I don't have a problem with the any engine dd15 isx15 isx d13 d16 3406 and so on worked on them all and they all have there problems and i look at it as job security
ОтветитьCat on Highway engines were the worst on highway engine ever when they introduced ACERT. You forgot to mention the low pressure Turbo taking out the High pressure Turbo when it failed and boy did a lot of them fail.
Cummins had problems with initially, many issues with their EGR cooler and VGT turbo ( specifically the shroud plate coming loose )
Cat should have kept it simple like Cummins did.
I had one in an '05 379 and absolutely loved it. Those compound turbos could drag a mountain up the side of another mountain.
Ответитьyou forgot to say when CAT got out of the on highway engine in new trucks.
ОтветитьCurrently in an 07 FL CL120 w/ Cat C15 NSX30749. And I cannot find any direct info on what exactly I have and looking on directions to tune it up right.
ОтветитьThank you I was looking to get a used glider with low miles that happens to have an '07 Acert. Currently I'm driving a 97 Detroit 12.7. I'm going to stick with it.
ОтветитьHey bro u havent done a single video on a 3176 b engine and theree are so many dump trucks with this engine, i wanna know more about it, i have a 94 peterbilt 377 with the 9ck serial number ecm , ive had to researchceverything myselfe as no California mechanics work on these older models, i can use some help, ime having issues with power with no check engine other than code 12, cus i dont have a coolant level sensor on my truck
ОтветитьMost with put added pressures or bigger injectors or programs made life hard.
ОтветитьJunk
ОтветитьJosh you are a great mechanic and have a ton of general knowledge thanks for sharing
ОтветитьCAT'S EGR system fails all the time in the off road engines. We have C15's in the CAT 740 and they fail more than any other engine around. The pecker head fails in the D8 dozers but the EGR fails and fills the engine with coolant and even hydraulicly lock it up.
ОтветитьI understand it's a delicate balance, but to put it in perspective, for me anyway was the realization that Cat added a second turbo to increase air in the cylinder, then IVA solenoids to relieve some of that extra air
ОтветитьThough not a Cat, I'll stick with my "new" reman extended long block N14, for only $25K from Cummins
ОтветитьYou are the cat man.nice info
ОтветитьWasn't the EPA-mandated type ACERT engine the engine that convinced CAT to get out of the truck engine business?
Edit: You answered in the video
Great video A Ape, I like your objective sarcasm on what cost the engine manufactures and industry billions. It's no wonder why Cat stepped away from over the road applications. The EPA continues to bring on the demise of the diesel engine.
ОтветитьAs an old technical writer, bless you for explaining the acronyms!
ОтветитьThat’s why I’m sticking with the 6NZ and 3406E
ОтветитьSomeone has done their homework!
John deere also started with twin turbo, vgt turbo ang EGR system in the early 2000 . In my opinion this changed the difficulty of being an diesel technician a lot.
You are very intelligent young man. Thank you for clearing that up.!!!!
ОтветитьGood stuff!!!!
Ответитьit'd be a lot easier to just Delete The EPA.
ОтветитьI am looking to get a 2007 F750 with a C7 what is the scoop on this engine?
Ответитьomg dude. use less nonsense conversation filler. reread your script and delete all your lines that serve no purpose. would make this a 7 minute video.
ОтветитьGotta watch this one again. A lot of good info there
ОтветитьACERT Advanced Combustion Emissions Research Technology. It worked in some engines. It was a very small injection of fuel before the injection cycle. The idea was to add fuel to fire (pre-ignition) at TDC +- (depending on flash file) and burn all of the fuel, instead of adding fuel to compression that caused ignition but did not burn all of the fuel before being expelled through the exhaust. Every injector fired twice which is the reason trim files were very important. Incorrect trim file would cause excessive fuel consumption. Great video!
ОтветитьI have a 2004 c15 acert ... million miles just got touched ... so far only had injectors done on it ... vibrations are the biggest problem I'm facing and also fuel filter changes very offen otherwise it doesn't even pull a empty uphill ...
ОтветитьThanks 👍🏻
ОтветитьIf it's not broken, the government will fix it until it is
ОтветитьI drive a 2004 school bus with the C 7 210 hp engine, it’s a good enough for me in the school bus but a few years ago a drove a 3406 475 hp in a KW hauling fuel and it’s a big difference in the power . Keep up the good job of letting us know about cat engines .
Ответитьmy 07 acert c-15 has never hit more than about 38 lbs mostly 32lbs . it does iva 5and 6 flashes hi current code.
