Cummins EPA27 X15 diesel engine first look | FE Unscripted

[@michaelprue9024]

I’ve been a diesel mechanic for over 35 years now. Spent the last 21 years at a major dealership for class 8 trucks. Have witnessed the evolution of the Cummins ISX engines (red engines) from the Signature 600 to the X15. I’ve been anticipating the new engine for some time now. Thank you for the sneak peek ! Lately my shop has had me focused more on the Paccar MX 13 engines, but I still get to get my hands dirty on a red engine every now and then. I really wished Cummins would interview different journeymen every now and then, I could have saved them a shit ton of money and heartache a while back when they switched to ceramic plungers in their high pressure fuel pumps. I spent a few years working for Stanadyne back in the early mid 90s in the durability lab. My job back then was to break what the engineers built. Back then the race to reach 30,000 psi fuel pressures was huge. Bosch P pumps could do it if you tweaked the pumps barrels, but stanadyne was having a hard go of it. They used super highly polished metal rollers and plungers, which would inevitably fail, and A LOT of machining and time went into making them. They came up with a new design pump they called the R.S. pump instead of the old DS design, and switched to ceramic rollers. Those rollers failed even quicker, and would wipe EVERYTHING out. In a lot of instances they even had to scrap parts they would normally be able to reuse, like the housings, and start all over from scratch. I knew as soon as I heard Cummins decided to go with ceramic plungers in their fuel pumps they would pay dearly, and they did. What a shame it is the government had to get involved in engine manufacturing. Forcing manufacturers to feed engine their own exhaust is like forcing a mother to feed her baby its own shit. It’s nothing more than communism, state run engine manufacturers, whose ONLY interest is to sell the public on electric vehicles this country’s grid can’t even begin to support. And the proof is in the pudding. Companies like Volkswagen I believe it was, Ram, and Cummins hiding emissions through sensor readings and computer programming etc says it all. Not to mention the fact that regular folks with knowledge are able to crack the codes so to speak and overcome aftertreatment technology and jail break ECMs in order to defeat emissions and put their personally owned vehicles on a diet PROVES the public isn’t in tune with this communist government. Me, I work within the boundaries. I own an L5P Duramax, and it’s bone stock aftertreatment and all. And it’s also a ticking time bomb I’m going to have to deal with eventually because I don’t want to break the law. I just wish GM would put a Cummins engine into their pickups. What a combo THAT would be. I love my Silverado, and Cummins engines just as much. Can’t stand Ram pickups, they’re literally trash, I know, I’ve owned them. I’ll pass thanks. But the engines oh yeah. Fuck you Uncle Sam.

You said that right.

Uncle Sam is the face for Uncle Moshie. Jews hate White Christians and the Japanese I'm learning. They want to destroy us and will do it in every possible way.

You’ll never see this engine in a military vehicle, because it’s not reliable enough for that application, but it’s ok for a guy that is relying on it to make his payments every month lol!!

[@ThorneRising]

Not entirely accurate. Military engines are far more likely to see combat than an over the road engine, and the complexities and dangers of the combat environment require a simple engine.

[@mikemorse8592]

All of this to make an engine that’s less reliable and uses the same amount of fuel as the N14. Uncle Sam killed diesel engines

[@theoregontruckerT880]

I went from a 2005 KW W900 C16 625 horse to a 2017 T880 with the last run of isx15 550 horse I’ve put 500,000 miles on it doing heavy haul 12 axle lowboy. Compared to the cat it’s stronger, doesn’t break down as much, uses less fuel, easier/faster to repair when it does need repaired.

[@isaiahanderson7237]

@@craigalston2208I agree. It was one of the best ever produced. Even the 2008-2011 Maxxforce DT was alright but still had typical emissions equipment problems. The heart of the beast was still the same solid block and heads used in previous versions.

Anytime your looking for a cheap , reliable , easy to repair truck buy a International Truck with a DT-466 engine and you will have yourself a 🥇 Winner . They're not pretty like the rest but they'll get the job done and pass the test . You're guaranteed to see more IH-466 powered trucks on the roads then any other commercial vehicles .

[@williekaminski3705]

The idea of an easy drain oil and filter design is actually pretty sweet. Chrysler has been using plastic filter housings for years and they hold up.

[@TellurideS13]

International already use these in the S13

[@harleye1235]

And Detroit dd13 and dd15. Chevy and Toyota have had them in cars for years too

[@BeverlyHolzworth]

So were back to 1960- 70 filter housings design , except the housing is plastic instead of steel so the plastic will warp or crack & then buy $$ a new one. So the old engineering was right 😂😂❤❤!!

[@Gtown9011]

International’s S13 Scania is the mother of all engines. No Egr and Egr cooler.

[@michaelbenoit248]

What I’m upset about is that the location for the fuel filter is where the truck frame would be vs leaving it alone. Of all the things Paccar did wrong they have their fuel filters located perfectly. In some ways I prefer the Paccar over the Cummins because of ease of service, and the troubleshooting is easier.

[@aaronfox5808]

I keep waiting to see the EPA chase run Cummins out of OTR engines as Cat did. Its a shame that reliability from the powerplant took back seat to the Government standards that care less about the loads getting there on time. I hope it works for Cummins and even more so for the Owner operator whom is paying the payments on the newest truck that may break down with little dealer support. I do respect and prefer Cummins X15 over all other junk on the market. Just concerned about reliability for the person buying and driving the rig.

[@hellohumans175]

they are building them for the big fleets, they keep them until warranty expires they don't care about little guys

[@theoregontruckerT880]

European engines are so much further ahead it’s crazy they don’t even use def anymore they’re actually able to meet emissions standards without after treatment and still put out twice the power of the average American diesel

[@nikoz4841]

What engines are you talking about? They do use ad blue, it's def fluid

They use def, they don’t regen that is correct but add blue is still used, I don’t think you really know what you’re talking about lol!

[@isaiahanderson7237]

Europe still has similar emissions laws as us. As for them creating more power, more power means more stress and wear. 500+ HP for a big rig is more than enough.

[@6.4DieselDoctor]

You’ve basically made it a pain in the ass to work on with the rear gear train especially if there’s no “dog box” in the cab. With set back axle trucks, these engines will be awful like paccar’s mx. And the fuel pump? Yeah I’m thinking this will be just like the cp4 bs but hey, I’ll gladly take the money replacing it along with the entire fuel system when it grenades.

So far, slightly more complicated. Don't like the placement of the fuel filter. Just pay only set the time $50 more For a heated fuel filter. Don't like the idea It's not programmable if you want to get more or less horsepowor or it have to be a only certified Dealer. Renewable oil A filter, good idea maybe wait till after market Where it's just metal Instead of plastic Unless a machine shop customer makes you filter, For those is unaware most shops tend to recycle the filters. Overall, not reliable For the first few years. Sounds like less horsepower But EU have big horse power and More of a Emissions system

All the American diesel manufacturers have been caught tampering with emissions. None of them have been hit quite as hard as Volkswagen, but Cummins was fined last year for their engines in the Ram pickups were not meeting standards.
