but i like this one. i still doubt it will take off, but i like it anyway

pretty neat, sounds cool too, i wonder why nothing ever comes of these inventions that people come up with, is the gasoline engine we have now really the best thing out there?
-
Interesting design, problem I see is the added complexity. :noel:
-
i think what we have now is so cheap to manufacture compared to something new like this and thats why it sticks around. i think people would also be scared off if they had a choice between buying a car with this engine and one with a conventional engine. kinda like the rotary, they werent big sellers and rightly so. who wants to mix oil into their gas at the gas station. lol
-
That is pretty damn rad.
-
Where are you guys getting this extra complexity from? There is zero valvetrain. Looks pretty simple to me.

Because it doesn't use a standard ICE engine configuration, duh.
:P
-
The head gasket is now a moving combustion seal just like the piston rings. I'd like to see how long it runs before that seal fails.
-
the only thing i see complicated is the "headgasket" but if they have a solid plan for that, then everything else is simple. everything can have roller bearings so there is no need for oil pressure. there is a lot moving, but not a lot of moving parts, its just a big chunk that looks complicated but its pretty simple. valve float, coil bind, broken valves, and piston/ valve contact are all non issues. you could boost the hell out of it and rev it to the moon.
-
the reason none of these designs make it to market is because of the people that have billions wrapped up in oil and traditional internal combustion engines.
-
Uh this is an ICE.
-
Uh this is an ICE.
no shit?
-
how much boost can it handle?
-
10 pounds on a duke will turn ya out!!!
-
its a gm ac compressor :P

its a gm ac compressor :P
LOL, it's true.

no shit?

No shit brah, for realsies.

I was thinking that too, since they don't mention "matching conventional reliability" anywhere. However I would imagine a bearing-like surface with oil fed onto it with a rubber seal. It probably has the same rotational speed as a large rear main seal on a larger engine, and they don't feed those oil, nearly all are just splash lubed.
The complexity is the parts themselves, but when you have 1/3 the parts that need 2x the machining, you've saved 1/3 of the machining time/costs. They already use a similar type of "pump" in some car's air conditioner compressors. The even cooler part about that, some of those compressors are variable-compression.

this one seems pretty cool as well

If ya speak German reminds me of some previously posted mighty mite engine.
