Trivoli, IL
getting side tracked by below couple threads.... go with the flow....

What would you say to John Deere's tractor engineers?

What to Say to Deere's Tractor Engineers - Thank you!

==============
in order to try and wrap up anything goes for engine search. and begin focusing on narrowing down the list.... going to finish out the few other engines i found...

it is a barrel / swash plate / wobble plate per say. but the pistons are rectangle shape. vs cylinder shape. it is a possibility. though i gotta question 4 seals that would be needed around each piston, and how long before wear and tear on the pistons deteriorates enough to really cause performance to go down quickly. and wondering what might happen to the pistons, if the engine "stalls" due to trying to overcome to much torque. along with if the pistons can withstand the constant beating / vibration from the 4 stages, of air intake, compression, explosion, exhaust, over a long term doings as in years. i would imagine the pistons could be made decently enough to last a handful of years, but say 7 years even 10 years? i honestly don't know, to much math, and material properties, and ways something could be manufactured / made. and most of which would most likely come from a specialized select group of folks.

to be honest not sure what to make of this engine. i see a lot of parts, that have "curved" edges that someone would follow or slide on, a wobble/swash plate kinda thing. but not sure how it works. the need for a simple animated diagram would help understand how the engine operates.

to be honest i originally passed up on this engine type/style many times. but seeing below page, help push things through. the issue i do have with this engine is the "casing" halves. and trying to hold back the pressure from the explosion, and not getting "leaks" and trying to micro manage how much torque each and every bolt got for the 2 casing halves. to make sure a perfect seal happen. and then making sure that all the bolts stayed at same torque (not loosening or tightening) over a longer period of time. other wise i do like the engine, variable air intake / compression, the external compression chamber, and then controled point of were explosion happen all looks good. but that "small wheel with grove cut in it, to let piston spin around". that wheel also has me, and pressure causing that wheel to become "warped" and to vibrate. ya i am sure someone could make it X thick, to beef up this grooved wheel. but don't know. past my knowledge.

it would seem to be a wankle engine manufacture alternative to the mazda wankle engine. though do not quote me on that.

from reading, it looks like another barrel / swash plate / wobble plate engine. but there is only a single huge piston in the center. vs multi pistons in more of a barrel engine. if i got that right, not sure about it. i guess it might work kinda like a "double acting hydrualic cylinder" it might have promise. if everything was worked out. but that large mass of metal going back and forth. it just sounds like a "vibration machine" waiting to happen. granted vibration most likely be reduced a good amount. but not sure if the overall mass could ever be compensated for.

not to sure about idea, turning piston into a cork screw pipe. it might have promise, but information is lacking, to make it useable.

see comments more of "cat and mouse engine" the engine makes sense. but for what ever reason, i want to back away from the engine. it looks like it is going into production, or is in production. but not sure at this point. the whole piston thing, and keeping the pistons from wanting to twist back and forth, between the 4 stages... and long term life span of the engine. perhaps it is just me. and i simply do not understand.
http://peswiki.com/index.php/Directory:Massive_Yet_Tiny_%28MYT%29_E...

there was other engine, that got lost some place along the line for a link....
--one of them had a "free piston" that bounced back and forth in a tube. the middle section of piston was magnets, and middle portion of the cylinders was coils of wires. basically it was a direct piston movement generator i guess you could call it. though i frankly dismissed the idea. due to creating a "vibration" machine. and possibility of something going wrong, and a piston slamming into either end of cylinder housing, and piston turning into a bullet shooting out of the engine. good concept, wish i had the link... but then again vibration machine might not be. if compression was happening to kinda act like an air bag cushion.
--really wish i had the link now...

if i had to choose engine right here today, it would most likely be a mazda wankle engine. and most likely entire engine dropped into the SSTT. with exception of muffler, air intake filters, and general plumbing of coolant (antifreeze/water mix), and engine oil locations moved about some to make it more feasible to actually work on within the SSTT, and to better fit the overall SSTT frame work. i would assume any problems a mazda wankle engine has now, would carry right on over. maybe fixing one thing, but another thing showing its ugly rear. i am guessing most of any additional problems would creep up in the electronic air injection system, and fuel injection system. and trying to tie it into everything else.

looking at a SBC (small block chevy) 350. the dimensions just to tall. at moment it is on the bottom of the list. and most likely would prefer to put cash towards some new tech engine that does not have a track record, vs trying to deal with a generic piston/cylinder engine like a SBC 350, and the height they would need, and problems that would result of that height.

below three....

the way SSTT is currently setup. has plenty of length, but small width and height for an engine. the current dukeengines setup might be best choice. playing around in autodesk inventor, and trying to find physical room to route, exhaust pipes, and air intake pipe work. and simply not enough room to route them past the engine. ya it could be done. but it looking pretty ugly and so cramped. that heat build up, would most likely cause a bunch of other problems. the current dukeengine, with exhaust / air intake only on one side. and to the point same side. might be a better overall option for SSTT. and being able to use up total 20x20 for the pistons/cylinders and not have to make them smaller to allow for air intake / exhaust.

engine size would fit the SSTT. but the entire outer mass rotating has me concerned. way to much garbage (leaves, steams, etc...) that could fly up between this outer drum of pistons per say. and get stuck between it and the frame work, and start a fire. if the outer drum of pistons was held stationary. and only the center rotated. this engine could be a good possibility for the SSTT.

might be something, but at moment, i am having second thoughts over it, vs other engines noted above.

below 2....

possibility, for the SSTT.

http://www.regtech.com
no idea about this engine. looks like a lot of work to route exhaust and air intake around the engine. if i am guessing what is inlet/outlet ports on the engine.

============
head is starting to spin... information overload, and trying to visualize things quickly in my head vs actually taking time in autodesk inventor to see things. time to post and let things soak for a bit to maybe narrow things down a bit more. granted at this point i doubt i will be able to make final selection and needing folks more up to par with various engines speak up. and until that point, only narrowing down approx engine HP, and approx dimensions, approx CFM (cubic feet per minute) of air intake and exhaust to deal with air filters, and exhaust pipe sizing.

at least now i know engine size can be meet without any major changes to the frame work for the SSTT (sideways snake train tractor) though finding locations to check oil, fill oil tanks, or coolant tank or like, still needs to be dealt with.

alright time to make spread sheet it would seem of specs.
