Cummins Advanced Combat Engine.

[dave_dj1]

You Cummins fans may know about this engine but I just discovered it's existence, pretty cool. 1000hp 4 cyl twin turbo with opposed pistons and a box shape designed specifically for military use.
Here is the video I came across. I'm not impressed with the interviewer or interviewee but the engine is cool nonetheless.

interesting....

For the lazy or those that don't understand what he means by the cylinder configuration.

that wouldnt really be opposed like a boxer engine

more like inposed? i feel like thats not a word and spellcheck agrees

 

[Tech Tim]

Opposed pistons, not opposed cylinders.

 

[SanDiegoCJ]

The opposed piston idea has been around since the late 1800's, but with the application of modern tech it's been refined. Simplified engine since it's a "2 stroke", no valves, cams, etc.

This will be the new “LS” swap craze in about 20 years.
you heard it here first.

Opposed pistons, not opposed cylinders.

You're supposed say, "opposed pistons, as opposed to opposed cylinders", unless you're opposed to using "opposed" more than twice.

 

[Arickvan]

It is an opposed engine and this is just another development of really old tech. https://en.wikipedia.org/wiki/Opposed-piston_engine


Still pretty neat. The napier deltic was an even cooler design of the type https://en.wikipedia.org/wiki/Napier_Deltic

my brain hurts

Cylinder firing order of the 18 cylinder Napier Deltic diesel engine: The grid represents triangular cylinder arrangement (banks A, B, C) and rows 1 to 6

Don't post that shit! Feliks will be busting the door down.

"Feliks" was the first thing I thought of, too

Seawolf nuke subs and all preceding them, still use Fairbanks Morse 38ND 8-1/8 opposed piston diesels for back up power, originally designed in the 30's. Definitely not a new idea for a military application.

Yup, primary power for U.S. WW II diesel subs.

You saying those are going to be all over Govplanet, like H1 tires? Sounds good to me!

It may make 1000hp but at nearly 4000lbs it may be a tad porky to shoehorn into a Miata.....

Wait. I missed the weight.

This thing weighs two tons?

14.3L isn't gonna be a lightweight.

 

[woods]

14.3L isn't gonna be a lightweight.

Holy shit.

Its that big. mmk. yea, I just breezed through and watched the video on mute. the video made it seem so much smaller (phrasing, boom).

 

[Thefishguy77]

It may make 1000hp but at nearly 4000lbs it may be a tad porky to shoehorn into a Miata.....

So I may have to brake down and buy a full size. We all make sacrifices.

Will continue to check govplanet in about 5 years

well since it's going in Bradley's and possibly other tanks.....

 

[michael.gonzalez]

Perfect for a deuce and a half.

I've got a Pair of them mounted on my pulling Tractor. Y'all need to keep up

You'll probably need a bit more than a 3/4 or 1 ton. A 6.7L Cummins only weighs about 1100 lbs. That's about 1/4 of the engine in the video.

Like most of the fringe research stuff that tardec(gvsc) sponsors it will probably never be produced. If it did it won't be epa compliant so it likely won't be able to be sold to civilians.
