2019 first look

[CUMMINZ]

Wife and I stopped by our RAM dealer today and looked over our first 2019 5500 C/C Tradesman and 2019 2500 quad cab. Nice looking trucks.

I hear that new graphite/iron engine block doesn't sit as high in the engine bay.

Guess we'll see if it holds up?

What does block material have to do with the way it sits?
It's an industrial engine first and foremost. Like any model year changes its bound to have a few hiccups but it will be solid overall.

Smallet engine block occupying less volume

 

[JR]

Explain please.

Saw a video review of the 2019 Cummins. I think it was the TFL truck amateurs who said the new cummins doesn't seem to fill the engine compartment quite as fully as the old one.
They made this comment in reference to what appears to be more room to work under the hood.

Don't actually know the dimensionsnof the new compated Graphite Iron block of the the new 6.7 Cummins engine to compare with the old cast iron one. So i don't feel like arguing with you about it.

Might be the new engine mounts might mount it lower. Maybe not. Might be since the new CGI material is reportedly stronger that they might use less of it. Makes me also wonder if the metal tariffs may have had an impact on the material used (especially if the tariffs are assessed by weight). The graphite might also be assessed a tariff? But graphite would weigh less.

My comments in this section are really just based on the video that said the engine looked smaller. I'm sure we will gradually get more info about it.

The bore and stroke of the new engine are identical to the isb. Wondering if the (expected) increased cylinder pressures are due to higher pressure turbo (air supply)? And increased fuel? Appearantly there are also different heads. (But still cast iron)

From the sinister cast website. Sinister cast help Cummins and ford cast their engine blocks.

SinterCast is the world’s leading supplier of process control technology for the reliable high volume production of Compacted Graphite Iron (CGI). With at least 75% higher tensile strength, 45% higher stiffness and approximately double the fatigue strength of conventional grey cast iron and aluminium, CGI allows engine designers to improve performance, fuel economy and durability while reducing engine size, weight, noise and emissions. The SinterCast technology is primarily used for the production of petrol and diesel engine cylinder blocks and exhaust components for passenger vehicles; medium-duty and heavy-duty cylinder blocks and heads for commercial vehicles; and, industrial power engine components for marine, rail, off-road and stationary engine applications. SinterCast supports the series production of components ranging from 2.7 kg to 9 tonnes, all using the same proven process control technology.

From what I have read, higher cylinder pressures are mostly because, with SCR keeping NOx emissuons in check, they are able to add timing that they had to take away starting 04/05(?).

 

[JR]

According to Cummins the new engine shed 60 lbs over the previous gen engine. Assuming 100% of that weight came from the engine block - which I doubt - that's a 5% reduction in weight.
I really doubt you would be able to see that just by popping the hood.

1st new 3500 showed up on the local dealer's website as being in transit. $86+K

comrades! are the 2019s still built in satillo ( spelling ) mexico or have they shifted to michigan yet? cheers!

My question is how you can determine engine size when the engine is basically invisible. I know the air induction is completely different on the 19's.

 

[Newsa]

Since people don't like what i said about the block possibly being slightly smaller, i will retract my comment and apologize for speculating.

I would expect some components to be somewhat beefier to handle higher turbo pressure and common rail pressure. I also imagine fasteners holding on the head and (let me speculate further and upset more) the cast iron head which is not cgi to be heavier along with the increased size of radiator.

 

[Newsa]

I will have to agree with JR, tho.

It is an industrial engine. I don't see any evidence they will produce the old cast iron engine block engines for industrial and produce only the cgi block engines for Ram. If they were only producing the new cgi for Ram (and reserving the cast iron design for industrial), it might be that they are not expecting the 10,000-20,000 hour longevity from the engine.
It may take a few years to fully transfer all of their B 6 7's to cgi, tho.

You will notice the cummins 5.0 V8 is mostly supplied to Nissan. Cummins lists a 4.5 liter inline 4 cylinder as industrial. But not seeing a Cummins V8 listed as industrial

 

[Cummins12V98]

No issue for me, I just wonder how a person could see it being smaller???

 

[mpaulson]

Some of the weight shed is in the mount brackets for things like the alternators etc. They are now aluminum as before they were cast iron. This was explained in a video that was posted here before.

 

[Wiredawg]

I personally would not be concerned about a CGI block holding up. Ball bearings are manufactured from powdered metal and they hold up. I just see the CGI block as great new technology to build stronger, lighter, and more powerful engines.

It would be really cool to get a tech briefing on engine, frame, and other components manufacturing processes and materials being used in the new trucks. I think frames would be interesting.

I agree that an new transmission with an 8 or 10 speed would be awesome.

Cheers, Ron

theres a new 6.7 at the dealer here. nice looking but first thing i noticed is how low it sits. pretty sure it 1-2" lower than previous year. i hear ford is lowering their trucks as well. theyre all look like chevy soon. i guess grampa got his wish
