To conceive of it is one thing; to actually build it AND make it work, is another. When I was young, I WOULD have thought of something like this but I NEVER would have been able to make it happen. You are a true genius, young man!!

[@TankToChest]

So the purpose of a boxer engine is to balance all the motion. This is a 180 flat twin. Boxers have thier own crank pin for each piston. This was done brilliant though man.

[@mandernachluca3774]

respectively a 180° V twin, technically speaking. ;D

[@MichaelSteeves]

The plexiglass crankcase worked exactly as well as I would have expected. It was a great proof of concept though, showed everything was working before committing to welding up a steel one.

[@jojojo7333]

Until now I was wondering why engines wasn't made of plastic ;)

[@NLynchOEcake]

I think in theory if you could somehow fit extremely long studs straight from one head to the other the plexiglass would have been totally fine. The problem with this configuration is that the crankcase is structural, so it needs to bear the load of combustion. Every fire, the pistons push down but the head gets pushed up - the crankcase needs to have enough tensile strength to withstand the force of both pistons trying to blow the heads off the cylinder, hence the plastic failing by the area around the bolts ripping out. If the studs could reach all the way through to each other the crankcase would take a negligible amount of force. In this configuration it would have been neat as an alcohol motor maybe.

[@trollbane66]

It actually ran a lot longer than I figured it would.

[@trollbane66]

@@NLynchOEcake I think you also would eventually see heat become a problem.

[@NLynchOEcake]

@@trollbane66 I think it would depend on if it were crankcase scavenged or not but in this case it appears to have an oil injection setup so exhaust in the case would be less of an issue. There would probably be issues at the interface between the cylinders and the plastic case though, cylinders can get bloody hot and would likely melt the case

@@yusufyakti flat twin has both cylinders on same crank pin. 1 is at TDC the other is at BDC. A boxer has each cylinder on its own crank pin and both at TDC / BDC together at same time. This gives better balance as the pistons are moving in opposite directions and primary balance is cancelled (except rocking couple due to cylinder offset) BMW bikes, Subaru, VW beetle/Porche are boxers

if you want it to run smoother, put a flywheel on it and lower the compression with more headgaskets. Also running camping fuel as well

Um... No, do not use camping fuel! It has very, very low octane. I would like to at least see him put the stator on it and make some electricity to charge a battery or something. Giving the engine something to actually do.

[@DatBlueHusky]

@@johnwyman6126 camping fuel would make the engine run cooler and smoother, why would he need to build it to make it work, its just an engine to show its working. he already has twin cylinder engines he made thats in a motorcycle

[@johnwyman6126]

@@DatBlueHusky exactly what is it that makes you think that running camping fuel will "make the engine run cooler and smoother"?

[@DatBlueHusky]

@@johnwyman6126 because i have actual model engines that run on it? Running gasoline is more powerful but creates more heat and runs harder. Camping fuel burns slower and lower heat making it run better. I dont see you having any videos so i see you are just a keyboard warrior lol

[@BrokeWrench]

A heavier flywheel would make it much smoother. Lowering compression and making it run on oil would slow the burn down but isn't particularly helpful as it reduces power significantly. More headgaskets will also affect the valve timing reducing power even more. Your engines are smooth because they barely make enough power to run. There is a reason they stopped using low compression oil burners once a reliable supply of fuel was available

[@edvinjohansson9625]

Cool build as always. Just two bits of constuctive critisism. ALLWAYS mask cylinder walls when sandblasting, even if the cylinder is just laying off to the side while blasting the head. Sucks to destroy a nice cylinder. You should also allways put a small amount of grease on the crankshaft seals. They can in some rare circumstances be destroyed because of friction before oil can creep its way in.

@@Avetho It is a great engineering exercise, but as you have stated, it is a flat- twin and not a boxer. A typical (Honda) underbone engine alreadyhas a lot of vibration and making a flat-twin would put high lateral loads(double) near the top of the rev range.

Zen or the art of craftmanship. Chapeau Monsieur, I admire and envy your skills. One remark: This is not a boxer engin but a flat 2. Or more accurate, a 180 degrees V2. In a boxer engin the pistons will move in opposite directions because every rod connects with a seperate crank on a flat 180d crankshaft. I can imagine that this was near impossible to achieve. However, in comparison to your accomplishment here, this is just semantics, splitting hairs. In enjoyed this video immensly. Thx.
