Edit: made a mistake lols
If I could make an engine, it would be a
straight six with 3 liters of displacement.
Aluminium block.
Dual electric compressors routed through an intercooler.
Water injection.
Koeninseg freevalve heads (basically valve, ignition, and injection controlled electrically)
48v amp.
how would you have it?

*googles incline straight six engine *
Just a typo I guess. But this gives me an idea.
Why are there no engines which incline as you said? An engine with different-sized cylinders?
Because it’s stupid, maybe. But I totally see it being a thing someone in the early 1900s tried to make. I’ll have that one.
But to answer your question, I’d love a V16 with a relatively small displacement, N/A.

The Chrysler slant-6 is at a 30-degree incline or “slant.” Does that count? :p

an engine with non-uniform cylinder size would be a primary-imbalance nightmare.
I’d love a V16 with a relatively small displacement, N/A.
that won’t happen, primarily because the more cylinders you have for a given displacement, the less efficient the engine is.

Yeah I thought of that next, but imagine a straight 6 where each cylinder is literally a different size... Would that work? You would have to tune it for days to make it work and have different-sized carbs on each, no?

you could make an engine like that, I suppose, but it would be a total bitch to seal and an unbelievable bitch to balance. and for what benefit?

It would look cool.
But maybe in a dystopia where the size of the car is incredibly important (I mean milimeters count, tiny amount of space) it could help deliver power while leaving some room for other accessories in the engine bay). This is Jason Torchinsky level stuff here.

I was confused, I meant slant six. as in, the cylinder heads aren’t point straight up, as in, having an incline. like in the bmw k 1600.
I guess language is a barrier, for as much english as I was taught I was let down by my spanglish brain.

Well I mean, it’d be a bitch to balance if the force each cylinder produces is different, but what if the shorter cylinders had more bore?

"Spanfeller is a twat" (theaspiringengineer)
11/25/2017 at 23:17, STARS: 0
it would make each cylinder output similar force?
It’d be a mess to be fair, I’m not gonna talk like an engineer because I ain’t one (yet).

Cool. The trouble with a supercharged VR10 would be packaging. It would be about 20% longer than a V10 but a lot less wide. Just for the sake of being weird, you could use oval pistons and shrink the length a bit. Due to the low displacement, you could have a pretty decent bore size and retain the supercharger without having the total engine be too tall - plus you could use a dual overhead valve (pushrod) setup instead of DOHC.
I think we’ve now built a supercharged pushrod VR10 with oval pistons that revs to 10k+.
"Nick Has an Exocet" (nickallain)
11/25/2017 at 23:22, STARS: 0
On second thought - the max RPM would be limited by the pushrod setup. Boo. Not sure what the best compromise would be there.

I think I read about a honda engine that didn’t use a crankshaft (I think)
Basically this engine recouped energy from causing combustion that would then make the cylinder move through a chamber made out of god knows what (thinking about magnets) and somehow this engine was way more thermally efficient.
If you could make such that each cylinder is fired independently and running at different speeds (perhaps higher torque from the longer strokes one and more power and speed from the short stroke ones) it would make some kind of wicked sense

use Freevalve, well... valves... no mechanical timing. its better and basically makes any design possible.
I’m thinking that you could stick that v10 in a bay designed for like perhaps a v8 or a v12 and because of the compactness of the engine you could make room for wider tires and more complex suspension components.

Freevalve is cool but it’s not in a single production engine yet ;)
Yep! I’m thinking MR engine layout :)
"Spanfeller is a twat" (theaspiringengineer)
11/25/2017 at 23:46, STARS: 1
However in order to use freevalve I think like you’d need a 48volt electrical system.

So does having uniformly-sized cylinders, which is why all engines do it.

No, its about solving problems.
