I’m not even going to attempt to describe it, as I can’t figure out a good way to make it comprehensible. You can see an animation of it here. To me, it looks like you’re going to have friction and syncronization (for lack of a better term) problems at the very least. It might work at a single RPM speed, but I can’t imagine it working well in a variable environment like you’d see in a traditional automotive application.
The issue I see is that, in order to turn the wheel, you need to lock the clockwise-most piston to the wheel, but then release it just before it connects with the second piston. The little pin that did that would have to be jumping in and out at a pretty ludicrous speed comparative to its size. I’d be worried that it would break.
Why not use a TESLA TURBINE? :smack:
How exactly are you expecting someone to use a turbine as a car motor? Or is this a woosh?
Ahah. Still, I’m not sure that a Tesla turbine would be all that much use in an internal combustion engine. It works through constant, low-speed flow, and I suspect wouldn’t really mesh with pulsing rapid blows of force.
I don’t think this is correct. If you look at the animation in the middle of the page, the Scotch yokes are each solidly attached to four of the pistons. They then drive the crankshaft in a way somewhat similar to the way piston rods drive a crankshaft. One big difference is that piston rods are pushing straight down on the crankshaft, so they’re just in compression. The Scotch yokes are enduring a lot of torque. The two Scotch yokes are synchronized by being attached to the crankshaft.
To the OP, I’m not seeing why this would have any more trouble working at a variety of RPM than a conventional engine. Other than the possible issue of metal fatigue with the Scotch yokes, I’d believe the engine could work. I’m not qualified to say whether it’s better than conventional engines.
Ahh, okay. I’m presuming it’s the two pendulum-like things rocking back and forth. That’s pretty ingenious (though probably not all that miraculous in the clockworking world.)
Sounds a lot like Chrysler’s 1963 model.
One thing that I like is how the fuel intake and exhaust ports just “appear” at the correct chamber when they’re needed (see the animation). But they don’t show you how they’re connected to the rest of the car. Image 9 from the March 2005 gallery is the best picture I could find. There must be some seals between the rotating and the fixed pipes. I’d be worried about those wearing out.
Sorry, no link…it was a regulat IC engine, but with no valaves. instead of valves, the head had a roatating cap. which had holes in it (instead of poppet valaves). Seemed like a good idea.
I can’t remember the name of it, either, but someone posted a link to it here on the Dope and the general feeling was that it wasn’t a workable design, really.
