    That engine is what is called aProof of Concept built in a Lab of a engine company around the early 1900s. Companies like Fairbanks-Morse had Labratoryies which they had to build Proof of Concept to make sure they would work and test prior to going into building a Proto-type engine. My Dad used to work in a Crane company which was started in the late 1800s and they had a lot of stuff like that!

      Nah, this is some guy's project that he made at home.
      This is NOT a proof of concept piece, made by a commercial company, to do testing on.
      It's WAY too weak and cobbled together with weird parts to be anything made by a legitimate company.

    So what you have is a four piston, four valve, single combustion chamber high expansion ratio model engine. Someone was exploring thermo dynamics trying to extract more energy from the fuel by increased expansion ratio. As others have said a proof of concept model, it deserves to be in a museum. The construction hours in that model shows the dedication the builder had, the construction techniques are brilliantly simple. You don't need big frame bolts holding the cylinders and heads down when all the forces are balanced by the other pistons, it's the crankshaft that holds it all together, brilliant.

      the crankshaft in my machinist/engineering opinion is not beeffy enough to withstand a lot of stress. after editing the video that was what I narrowed down to the weak link in the structure of the engine. despite looking big in the video because how close I filmed the journals are only about 5/16 thick . with no bearing braces from the upper throw and the lower throws it almost has to be flexing as it runs. that and the home made chain. I had to readjust the tensioners twice top film what little running I did .

    This type of vertical opposed pistons engine was the trademark from a French car manufacturer named Gobron-Brillié. They produced big luxury cars with 2, 4 and 6 cylinders with opposed pistons from 1885 to 1922. Their biggest 6 cylinder had a displacement of 976ci ! Most of these engines had side-vales but in 1921 a sleeve valve version was offered.
    They were the first in 1904 to hit 100mph (103,55mph) setting thereby a new land speed record.

Drill tiny holes on top of piston that channel to ring center with pin as to stay in one spot ( 90 degrees to rod. The combustion pressure should then bleed to center of ring helping expand it against cylinder. Run good synthetic oil or 100 :1 premix ....it will lube piston/ cylinder and help seal it.

The o rings would outlive the engine if ran much as it's not built to be ran very much. And neoprene o rings can handle the heat and pressure. Aswell as they seal.on the poorly machine bores of the engine.

    • @vumba1331
      @vumba1331 11 місяців тому +2

      That's what I thought, all of the driving forces taken by the 3 opposing rods within the cylinders so minimal crank case load. Interesting to note at this time that there were a number of 2 stroke air cooled motorbike engines that had 2 cylinders with only 1 spark plug working through a shared combustion chamber and they workd just fine, there are still people restoring and riding them. Perhaps that configuration was all the rage around this time, maybe ignition setups and plugs were expensive, hence this design attempt?

    It's not an opposed pistoon engines but seems to be based on Doxford and similar ship engines which have a vertical link to upper pistons.

    The O-rings won't like combustion. Stretch the worn-out rings (expand the gap). I wouldn't worry about heat treating them, because it won't run enough to cause much wear. Maybe just to soften them (before stretching them), so they wear to fit more quickly.
    I wonder if expanding snap rings come in the right size to be piston rings, they're close to the proper material & hardness.

    • @cruddycornstalks
      @cruddycornstalks  11 місяців тому

      Neoprene o rings are rated for high temp and high pressure aswell as beig low friction. Model builders use them all the time as they seal a lot better and easier then normal rings . You would need to heat treat the rings otherwise they won't ever seal better as they deform from us and won't work properly. They need to be able to spring open against the cylinder wall. The rings in there current state would deform my hand without any efforts and felt like bailing wire.

      @@cruddycornstalks no (factory produced) engines use o-rings for piston rings for a reason, but I guess that engine can't run long enough to cause severe wear issues.
      It does sound like the OE rings are very soft already, and probly can't be hardened. The expanding snap ring idea is sounding better!

      @@Iowa599 the o rings are a better choice on an engine like this. We aren't dealing with a high use "factory produced" engine. It's a model. The cylinders are not machined very well and the o ring will help seal against that. And it's a lot less friction so the engine will run smoother. Aswell as o rings are dirt cheap and the day they wear out it cost a couple bucks or less to replace 4 of them. But as I have seen in other projects I've worked on. Neoprene o rings will last decades In some models or even fullsize hit and miss engines do to how little they run and how cool they run. Have some engines in my family that have one in them longer then I've been alive.

    Very cool. Perhaps you could show how the engine is

    My understanding is that you have one combustion cylinder with opposing piston tops facing each other. The combustion happens once while opposing pistons are at tdc.

    Just two main bearings supporting three big ends is not a strong design. Two cranks would not have been any heavier as that would lose the central link rod and crossbar. It also loses the valves and doubles the power strokes.
