Lotta people hated seeing new things 12 years ago…. Most of us still hate the after treatment 12 years later. But the 6.7 really is a great little engine she pulls well and gets solid fuel economy especially paired with the correct transmission. I’ve seen a few of these in 26 foot box trucks get to a million miles. Most of them get worked to death and maintained poorly and need overhauled or replaced after 400k depending on how bad it was Beat on. But 400k or more on the trucks these go in takes a long time very few are over the road. So now that it’s been a while I just want to say, it’s not the venerable 5.9 but it’s a good engine capable of very solid performance and solid fuel economy. The high output 6.7 in the ram trucks this year has 420hp and 1,075lbft. Of torque, the average semi is putting down 400-500hp and 1500/1750lbft of torque with an engine twice as big…
my school just got one of these engines (a 2014 model with the CM2350 ECM) as a running training engine; and it looked just as good as the Navistar Maxxforce Display Cutaway we got a few months later, only the Cummins Both Looked Pretty AND Made noise!
Seems to me that everything that reduces pollution decreases efficiency ie. increases fule use (decreases mileage), increases vehicle and service cost, decreases reliability (especially in cold climates), increases complexity. And, pretty much everything that increases efficiency ie. decreases fuel use decreases pollution as well. Seeing that the price of oil will only ever go up at an accelerating pace, the focus should be on improving efficiency. Decreasing weight, friction and drag as well as hybrid drivetrains...
less weigt, less friction in the engine, less friction in the gearbox, less friction in the final drive, less rolling resistance in the tires, less aerodynamic drag, more energy options (bio-gas,, natural gas, ethanol, electricity, bio-diesel...), more people in the same car...
The DPF system is the biggest problem I deal with on the dozens of trucks I work on. The utility companies using these are constantly having issues and needing forced Regen cycles. Talk to your medium duty, power company guys. You'll get a ton of feed back from them.
@@Makedoniadunek there's also a differential pressure sensor next to the EGR valve and its ports get clogged and a sensor behind the intake heater grid that gets clogged. It's at a 45 degree angle and takes a T15 bit to remove. (IIRC)
I have my 6.7 in my ram deleted. Not sure if they are similar motors to the ISB but it runs so good after gutting all that EPA crap. 25mpg on the highway
I have a 2005, 2500 with 4:10 gears, 11-1/2" ring gears, 216,000 miles and still get 20+ mpg on the highway. 2006 was the last good year before the crap was added. Only catalytic converter and muffler.
Wtf like for real 🤣 engineer are not mechanics. You don't put ecm directly on the engine. Nor electronics due to heat fatigue. Plus Cummins build good engine but due to faulty emissions system it fails as a true Cummins

The Cummins sound is unmatched. One listen and you can tell, its proud to be a Diesel!

I love mine in my m2
Yes you tested the DEF in a dry hot climate, bring it to Florida and the humidity, game changer!
Why? Here in Brasil we have no problem with this engine

EGR sucks ass!
SCR systems urea gets urological problems in the cold...ie. it sucks ass!
Anything that increases complexity without increasing efficiency sucks ass!! Plain and simple.
And the best innovations decrease complexity and increase efficiency! Way to go!
These are on the STM buses in Montreal

I'm working with VDL bus 🚌 year 2014 6.7 isb engines . have changed turbocharger,dpf, new injectors adjusted the rockers and still dpf getting clogged

@@fuzzynutz069
I've been changed both differential sensors.
Thanks for the feedback 😊
I noticed the egr cooler was clogged to, 🤷 I will sending it to cleaning..
Cummins engineers give us a hint to delete it.... right?
Delete what?
@@felipequintela3254 emissions
Better fuel economy? lol yeah right. Try 20 percent less fuel economy. Along with an 8000 dollar exhaust system that has a lifespan of 100,000 miles.
These engines can move a 38 foot plus motor home??
Idk but my 37 foot has one and it drive just fine with a Jeep behind it
x fabor podrian traducirlo al español para poder entenderlo mucho mejor y tambien podrian enbiar un vudeo de sistema egr. y circuitos neumaticos .
Mejor piedele q t ensene ingles
This video is 2010 and I threw up alittle when him proudly mention “egr” :(
the 6.7 is a great engine but I wish the EPA didnt stick there nose in this .. thanks to them the 6.7 won't show it true horse power until it deleted

I wish Cummins took time to make their engines sound more vibrant. Instead, they sound low quality, loud and even more so, unattractive.
