Each time I see "efficient" inline carb engine it makes me nostalgic for the old versions, where you could get 20k PPM at 100% with 4 turpos per cylinder and engine large enough. Basically it was budget RTG with tradeoff being it's ridiculous volume.

I'm fairly certain that turbochargers gain most of their efficiency boosting potential at low gas pressure and get diminishing returns as pressure increases. In practical terms, it's better to split the gas from the cylinders equally among all turbos at once, rather than feeding it through each one in sequence. It doesn't matter once they're all getting used to their full potential, but it would increase the efficiency of the turbocharger stage when the injector stage isn't running yet, as demonstrated in the video where the last two turbos weren't getting much pressure. I do find exhaust pipes to be a confusing mess, and I understand that it might make it harder to fit them all together in the desired form factor this way.

I remember making some like this back when I was making engine rafts before they super-nerfed the turbo.

My monkey brain doesn't understand, but he's trying.

The engine certainly could use some work, 2/3rds of the power comes from the injectors, and that means the PPM can’t be much higher than 450, and doing the math, the PPV is about 29 across the whole engine, I’ve been able to make an engine with about 30ppv and 780 ppm, In short, While serial engines are cool concepts, thier true viability is somewhat questionable. I’ve dabbled in them too, but I’m not much further ahead than you

It would be interesting to have a serial set of 3D carburetor tetris The first set is the base set, then the turbocharger section kicks on Then the final set of pure 3d kicks in if you need more, and potentially feeds the turbos (maybe a second set of turbos) I don't know that serials with injectors are likely to work out maths wise, since you can get very power-dense, cheap, and 500ish PPM engines from just 3d carbstacking

Great engine set-up for variable draw vessels like airships. I'll be adding this to my 'call it research' folder

This is a neat engine. Gotta give it a spin at some point.

I *almost* arrived at this sort of solution ages ago. I've of course done different engines with different priorities. Mostly 1T vs 2T engines back when turbo engines ruled the day. And back then I did try throwing a few injectors on an otherwise turbo engine to make more gas, but found that at the time it wasn't worth it. Never really tried taking exhaust from one engine and using it in another as far as I can remember. Might be a concept worth revisiting. See if I still have my old turbocharger prefabs if they even still work after all this time. Then get to testing for the right balance of injector to turbo for optimal gas usage. Probably would actually want multiple turbocharger engines - a smaller one to run off the superchargers and it's own exhaust, then a second bigger one that kicks on with the injector engine.

I think the last turbo has the exhaust intake and out flipped

The surreal cereal killer serially killed cereal.

I just got done taking all o the fuel tanks out of my engine prefabs, as I used to have the gaps filled with fuel (up to their max use) which is a liability now that causes fires, and can take a tiny bit of damage to an engine to "whelp, that engine is gone now"

Always good with some more exposure! I feel folks are not using multi stage engines even though they are good!

Do not forget cooling. You need lots of cooling to get the numbers you saw.

Maybach HL230

I should send you my prefab. Its a fairly efficient no priorty engine. But very inconvinient lol.its has much better power density I'll guess.

About seriel or chain engines there's alot. Alot

cereal 👍

Learning so much for this game. At which hour mark do I get to start the campaign? xD

dude years of playin the goddamn game and u still tryin to understand the fuel engine...
