Z-Dreamer Posted October 7, 2008 Share Posted October 7, 2008 Check out this company that claims to have invented an "80% fuel efficient Green Engine". The videos are a must! http://peswiki.com/index.php/Directory:Perfect_Motor_Corp:Turbocombustion_Engine Mark Quote Link to comment Share on other sites More sharing options...
woldson Posted October 7, 2008 Share Posted October 7, 2008 Now that one get my vote as a engine we may see on the streets!!! Hot dang that is simple, empolys proven tech in a very simple design!! FANTASTIC!! Two thumbs up! Really this could work! WOW! It is like haveing a rotory, recipcating piston, wankle, turbo charged all wrapped together!

jerryb Posted October 7, 2008 Share Posted October 7, 2008 Sort of looks like the cyclone engine.... http://forums.hybridz.org/showthread.php?t=137740&highlight=steam+engine From my perspective its still a combustion engine and carries the environmental baggage.

blue72 Posted October 7, 2008 Share Posted October 7, 2008 How about a man who thinks he may have accidentally stumbled upon perpetual motion, or at least a way to make electric engines much more efficient?

Derek Posted October 7, 2008 Share Posted October 7, 2008 What's interesting to me is they offer the 3D cad files for download and seem to encourage people to make a test model. http://www.tcengine.com/Parts.html You don't see that happen too much!

Z-Dreamer Posted October 8, 2008 Author Share Posted October 8, 2008 Imagine if you put magnets on the outer rotating assemble and then put a sleeve over it with windings, now you can generate electricity! Mark Quote Link to comment Share on other sites More sharing options...
m4xwellmurd3r Posted October 8, 2008 Share Posted October 8, 2008 wow, I like this design, it's simple and unique. instead of having the piston do the combustion stroke, the outer ring becomes the combustion chamber. the expanding gas rotates the large ring, which in turn turns the crank and piston. the small cam built into the crankshaft operates the two valves that are integrated into the piston assembly, and when the gas ignites, it looks like the ring timing makes the flap pop open as well, forcing the gas in, then shutting as it expands, then pulls in fresh air/fuel, right? I understand it in my head put words fail me. it's a really cool design. I wanna see someone build it. Quote Link to comment Share on other sites More sharing options...
woldson Posted October 8, 2008 Share Posted October 8, 2008 It also looks like it would be capable of very high rpm. I like the idea that it could be made into a gen set as Zdreamer mentioned. Wonder if the engineer thought of that:). It would be very compact. Seems like it would also generate significant torque. Quote Link to comment Share on other sites More sharing options...
m4xwellmurd3r Posted October 8, 2008 Share Posted October 8, 2008 that's what I was thinking too. and it looks like you could make it some what stackable like the rotaries are Quote Link to comment Share on other sites More sharing options...
AK-Z Posted October 8, 2008 Share Posted October 8, 2008 3 things I see wrong with it. 1. maintenance 2. balancing 3: lubrication And that center eccentric and lack of a counter balance kind of concerns me Quote Link to comment Share on other sites More sharing options...
m4xwellmurd3r Posted October 8, 2008 Share Posted October 8, 2008 the outer ring would act as a counterbalance I think. so in a way it would be an externally balanced engine. Lubrication shouldn't be too bad. it looks like they use some sort of ball bearing system, so if they had a way to add oil pressure behind that, I think it would stay lubed up fine. Internal maintenance may be an issue, but from the looks of it, externally, that shouldn't be much of a problem either. Quote Link to comment Share on other sites More sharing options...
woldson Posted October 9, 2008 Share Posted October 9, 2008 I did notice that changing the plugs might be tough, but that was it. Quote Link to comment Share on other sites More sharing options...
HowlerMonkey Posted October 9, 2008 Share Posted October 9, 2008 Until I see a video of it running and not sounding like it is eating itself to death like all the other miracle engines, I won't be believing it. Quote Link to comment Share on other sites More sharing options...
woldson Posted October 10, 2008 Share Posted October 10, 2008 Until I see a video of it running and not sounding like it is eating itself to death like all the other miracle engines, I won't be believing it. Understood completely. I will say this, the turbo charger uses the stuff that would be normally waisted. This by far the best design I've seen to capture as much of the energy from one timing event produced from combustibles. Quote Link to comment Share on other sites More sharing options...
m4xwellmurd3r Posted October 10, 2008 Share Posted October 10, 2008 I agree on that as well. everything is done in one stroke, with no waste. the power and exhaust strokes are done by the outer ring, and the intake and compression take place in the piston. I think it's a very efficient design. I wonder if you could turbocharge this design lol. it would be pretty interesting to say the least.

Challenger Posted October 10, 2008 Share Posted October 10, 2008 3 things I see wrong with it. 1. maintenance 2. balancing 3: lubrication And that center eccentric and lack of a counter balance kind of concerns me But isnt the outside moving the opposite way as the crank? So wouldnt it balance it to a point. Also, this is the "most fuel efficient engine designed!!!" Now they have to do the hard part, build it and make it work.

HowlerMonkey Posted October 10, 2008 Share Posted October 10, 2008 OK.....I finally spend some time looking at it and understand it now. all I have to say is LOL Quote Link to comment Share on other sites More sharing options...
woldson Posted October 10, 2008 Share Posted October 10, 2008 http://peswiki.com/index.php/Directory:Perfect_Motor_Corp:Turbocombustion_Engine#Independent_Testing Frist viedo on second link. Even cooler to se it built in 3D. They build so pretty cool engines out side of this project. THe read is cool too!! Quote Link to comment Share on other sites More sharing options...
AK-Z Posted October 11, 2008 Share Posted October 11, 2008 But isnt the outside moving the opposite way as the crank? So wouldnt it balance it to a point. Counter rotating doesn't necessarily result in balance. From what I can tell, the eccentric on the crank is used for the valve timing. I could only imagine the amount of vibration that it would produce (really, I could only guess). I keep a pessimistic view when it comes to engineering, because thing rarely work as they should the first time out Quote Link to comment Share on other sites More sharing options...
(goldfish) Posted October 12, 2008 Share Posted October 12, 2008 I would think it would have terrible emissions, the combustion chamber looks horrible. same problem as the mazda rotorys. Quote Link to comment Share on other sites More sharing options...
