there's a dude on eBay trying to sell a patent for a rotary that's based on a 1908 design for a steam engine. People in the other forum were talking about the viability of the design, without addressing the fact that all the guy has is a computer model showing spinning. NO seals, etc.
So I whipped this up in Flash to show how easy it is to create wacky engine ideas that seem like a good idea: http://www.rotorhead.ca/mystuff/dummyengine.swf on the surface of it this engine would seem better than a regular rotary or piston engine. -no valves -few moving parts -piston aids in high compression of fuel/air mix -piston aids in exhaust gas recirculation to burn up unburnt gas -engine captures long band of thermal energy and wasted force normally seen on the side housing of the combustion chamber on a rotary -crankshaft can be used to drive blower, alternator, & other accessories without scavenging power from the eccentric shaft -and so on, but you get the point. Anywho, the 'free' power from the crankshaft is a myth. The crank would have to be linked to the exxentric via a timing belt to make sure the piston is where it needs to be in each part of the cycle, so you're still scavenging power. Plus you're adding weight and complexity to the design (imagine trying to get in there and change that sparkplug nestled between the rotor housing and cylinder sidewall!) |
So what is it you do for a living again??
Nuclear fusion physics? Wow, I'm impressed! Nice to someone with an actual thought process! |
I *was* an electrical & mechanical engineer. Now I write & direct movies and operate http://www.rotorhead.ca

all this was too musch to read.
Do you have a link to see the guy on e-bay's idea or was all the pics what he was using to sell this petent? |
He just had a few animations, along with a text version of the books wankel dreams scanned (that's how I knew he was using the 1908 design- it was right on his website!)
