Guest 420GSXR1000 Posted June 28, 2005 Report Share Posted June 28, 2005 whoa.....its a rotary with an extra side..interesting though, gotta love mech. engineers!!! Quote Link to comment Share on other sites More sharing options...
Lustalbert Posted June 28, 2005 Report Share Posted June 28, 2005 Very intersting. Makes m wish i had the tooling to try and build one just to fuck around with. Also to see how it responds to our usual bag of aftermarket tricks. Quote Link to comment Share on other sites More sharing options...

You need asemetry to create real power and torque. Quote Link to comment Share on other sites More sharing options...
Lustalbert Posted June 28, 2005 Report Share Posted June 28, 2005 after looking around, aparently there is already a chainsaw that uses this engine. It is still in its prototype stages, but there are functioning units. so in therory, one could just use one big square shaft on this engine, and stack as many housings up as the shaft could handle without flexing.

large_x7 Posted June 28, 2005 Report Share Posted June 28, 2005 So explain to me a couple of things: 1. How does this thing get away with "nearly oil free operation" All machinery with moving parts requires some sort of lubrication to operate. It looks like this thing would need to have an oil injection system just like a rotary engine. 2. Fewer moving parts than what? A V8? There are 8 parts per chamber (it looks like the "carriage" is made up of 4 individual pieces with a hinge, but I could be wrong), which is about 7 more than my rotary has. It's a neat concept, sure, but we're all gonna be driving hydrogen powered fuel cells before this thing sees any real-world applications.

ohio_wookie Posted June 29, 2005 Report Share Posted June 29, 2005 Go Here I havent spent alot of time on this website but it looks like this engine can work with steam, pnematicly(bad spelling and grammer), gasoline and more. It looks like this thing could have some potentian Quote Link to comment Share on other sites More sharing options...

It looks like this thing would need to have an oil injection system just like a rotary engine. The only "oil" it needs is on the barrings of the carrages... in which case id say it would be more like axel grease. With the carrages riding on wheels around the housing, the friction is next to nothing. Rolling friction is on both ends of the spectrum. The friction is VERY HIGH when used with say ABS. But its very low when there is no power is needed for acceleration (both positive and negative). Think of a train wheel against the track. Almost no friction there, no need for lubing the outside edge of it, just a good polishing. Quote Link to comment Share on other sites More sharing options...

Too expensive, short term trial run, something for the hippies to like. Just start making LPG conversion kits for cars and all will be gravy.

I'm guessing it's the latter. graemlins/nonono.gif Quote Link to comment Share on other sites More sharing options...
Lustalbert Posted June 29, 2005 Report Share Posted June 29, 2005 Originally posted by Swirl Marks: Problems with your argument: [*]A train wheel is a poor example. The train does not slide across the rails, the wheel rolls. The wheels inside this engine also roll, not slide. There are 2 variations of this motor, one with caraiage, and one without. As far as the sides of the rotating assembly sliding on the inside of the housing, it should be similar to a wankel in terms of friction loss. The problem I can figure out is how the wheels in the cariage keep from building up any carbon deposits. Even if it runs really lean, eventually there will be some carbon build up on the wheels, or in the bearings. I think this would be especialy true if it had to have oill injected or pre mixed like a 2 cycle or bertos rx-7. Quote Link to comment Share on other sites More sharing options...
Science Abuse Posted June 29, 2005 Report Share Posted June 29, 2005 wheels would be a bad idea because where they meet the housing would be the most critical point in the motor, compression would rely on a tight fit, almost an interference fit. But, if you have that, you have force and friction, and very very short bearing life. Quote Link to comment Share on other sites More sharing options...
Mensan Posted June 29, 2005 Report Share Posted June 29, 2005 Albert, my argument was in reference to his satement that "no power is needed for acceleration", not this engine which obviously uses rolling mechanisms. The rolling mechanisms are nothing like a train wheel, which has thousands upon thousands of pounds of perpindicular force acting upon it. The very idea that it would be anywhere near frictionless is laughable. Quote Link to comment Share on other sites More sharing options...
1Quik7 Posted June 29, 2005 Report Share Posted June 29, 2005 trains are very efficient, when compared to the amount of weight they are pulling in contrast to the power being supplied. only a few inches of the wheel are in contact with the track at any one time. friction = traction, if the track was oiled the train wouldn't go anywhere, that is why they sometimes spray sand onto the track ahead of the wheels to create enough friction/traction. the only way for this thing to be completely "frictionless" would be to use MAGLEV technology. just my $.02 Quote Link to comment Share on other sites More sharing options...

There is a (heaven forbid) apex seal that rides in a slot in the middle of the caraige assembly that makes the seal.

I just wasnt sure if you where refering to the cariageless angine only, and hadnt seen the caraige type. Quote Link to comment Share on other sites More sharing options...
