I dont -think- this has been posted, but I wont be surprised if it has been. I searched for 'revetech' and didnt find anything so here goes.
Sort of a new take on a boxter engine, though they tossed in some bits that look like they came out of a rotory engine, and it doesnt rev very high, but it sounds pretty sweet.
Revetech
They claim that many existing parts (such as valvetrains - etc) can be used on these things, they have less moving parts, no side load on the piston/cylinder walls, and a 4 cyl engine has 6 power strokes per one crank revoltution. If fitted with a different rotor it can have 10.
Image
This allows for an assload of torque compared to standard engines of simalar displacement.
Anyway, makes a good read - and its very cool to see someone thinking outside the box.

and a still of the internals...

hmm...very interesting idea

I want to see how far it will go.

yup, might have the potential to be something someday. though i dont see many manufactuers instrested in spending money on a new engine design when they would rather be trying to find ways to do the hybrid thing or whatever else.

I'm not terribly mechanically savvy, so I have no 'opinion' on this, other than to say it sure looks cool.

(hey, at least I'm honest!)

Looks like my indian relatives are good at things other then working for Dell's technical support!

hey i need to read it a few more times to fully understand whats going on. it looks cool, it works. http://****************.com/smile/emthup.gif

I dunno, a new type of crank and efficiency skyrockets by 60%? That seems way, way too optimistic.
And I wonder how they would extract output from a row of pairs of piston, i.e. an H6 or H8. How do you connect the middle cylinder with a crank shaft?
It seems like you could get an H4 to work by getting power from both sides.

Re: New engine design - Revetech (TurboWraith)

Actually, I think the concept sounds great! I'd like to see an animation of the engine internals in motion because the description doesn't really give a good indication of how it works.
It doesn't sound yet as though there are any major drawbacks, but real-world testing will tell.

yea, you really didnt read very close.

i found an animated gif on their site, ill have to post it up.

It sounds very interesting, but just from reading the description I'm having a hard time figuring out exactly how it works. The basics of it seem right though. However their claims seem very optomistic (not that it surprises me).

heheh, funny - not a whole lot of intrest i guess. figured TCL engineers would come out of the woodwork for this one.

The armchair engineers run away when something is past the initial concept stage.

does the site tell you how to pronounce it?

i dunno...ive been reading it as RevEtech (capital E is long with accent on tech).

mike brings up a good point, wear in the cylinder walls would be down, but those rotors could wear pretty hard.

Wouldn't there be similar wear compared to a cam lobe? Without delving deep into speculations about forces exerted on the larger lobe versus the lobes on a cam, I can't imagine that there'd be much difference in wear.

no, not really
a cam lobe is spinning to push a much less massive part. those rotors are being pummeled by an explosion and a much more massive part is doing the pummeling.

but, they have working models, and they already have cars running with them, i would hope that they have it worked out somehow.
