I would follow all the comments. Use a 90 degree offset for the cylinders and use a switchless or modified switch design. That combination means you will reduce shaking and not need a big flywheel. The train is an excellent original idea! Every other LPE seems to get used in a car. As you progress, you could add tanker cars to supply the air for the engine. Like how a real life train supplies air to tanks on each car for the brakes.
An idea I have is: Make a depressed flatbed that holds the engine, then run a drive axle to the loco. You'd be able to add weight, and possibly shock absorbers to the flatbed. It may help a bit with the shakiness of the engine, as it's lower down and a bit more stable. It's a similar principle to a railroad slug in real life--except that the unit with the engine doesn't have any motors. I'd also recommend using a pair of U-joints as a coupling between the loco and engine car, instead of the magnets!
If you put a 90-degree crank offset vs. the 180 you have now, you won't have to start the engine by hand it will start by itself once the preasure is add still a very sweet Loco Great job
I would recommend having the flywheel parallel to the direction of travel, I think if its perpendicular that is whats causing it to wobble more. Also I think you could get it to work with only the universal joints and no worm gear if you have less of an angle in the universal joints, because the more extreme the angle the more friction it will cause.
the flywheel axis of rotation is already parallel to the direction of travel. perhaps you mean parallel to the axis the bogeys rotate on or perpendicular to both the axis the bogeys rotate on and perpendicular to the direction of travel
bro's got that "you are my sunshine" ahh exposure (means the focus of the camera is on something darker than white - like the black lego pieces on the train - which heightens white color intensity)
its a great concept, I think you need to make a it a diesel locomotive so you have room for a bigger engine, that way you can use a bigger piston or more cylinders I might try to build one on my channel, that would be a good build-off, to see who's is better, i think that would be fun. just let me know if your interested.
Lay your pistons down so they're going with the length of the car. May be able to add to the other side for a boxer layout with the bigger pistons that way too. May have to use a chain to go from center of car to your drive shaft but it'll have a lot more power. Also, smaller gears have more resistance. Putting those two 8 tooth gears in there was making things worse
The universal joints need to be 90 deg round from how you have them then the speed up and slow down ofvthe half shaft is balanced. Mind you that is a moot point for your 2 cylinder 180 deg engine.
I'm not an LPE engineer, but from I've already watched I think a switchless LPE should generate much more rpm, reducing shakes. Torque of course will be higher too. And the engine will be smaller. Try also build it in B4 - boxer generates less shake. Yo to all AFOLs.
Don't forget to turn on subtitles!
dude i was so confused, i saw subtitles but did'nt here you're voice, i turned the volume up like three times,lol
@ManosLC , it’s like a very janky experimental prototype of a shutter and I LOVE HOW JANKY IT IS, it’s adorable

The engine does not have much torque. You'll need to add additional gear reduction or make a more powerful motor.
Nope flywheel neets to spin faster and crankchaft at 90degree angle
@@Bobobob394 Flywheels do not create energy.
@@PyroteknikidFlywheel will save energy and help engine run
@@ohnocoder No it wont. A flywheel is a mechanical capacitor. It does not add power to the machine.
@@Pyroteknikid I already said this lol. Flywheel's inertion will move piston after miss strokes

Itd be sick if you had the engine powering a lego motor as a generator for the trucks

It didn't suck to me, It was a great experiment in my opinion and keep trying on improve the technology for next time :)

The design of this is pretty similar to the CliShay locomotive, steam engine mounted to the middle of the frame and uses gears to power two trucks.
I think some kind of turbine will work better with this
you should make a steam engine useing the air, make the rods move with the wheels
The comments on this video make me happy. Everyone is just trying to be constructive and help the build improve. UA-cam needs more of this.
Super. 💙 T.E.N.
Not to be such a critic, I noticed 3 things wrong in this design.
1. Center of Mass is not Lowered enough.
2. Not enough Torque.
3. Small Flywheel.
I didn’t know there were others working on the same project idea this recent… maybe not as niche as i thought!
Maybe try 4 pistons with a 90 degree offset
Mabye if you add a bending point in the middle of the train it will go smoothly
Why not just have a generator that can power some lego 9v tracks? That way, you can have a much bigger engine.
Waiting for the pneumatic lego tank

Try adding a differential
I built a high rpm engine from his instructions. I am going to run in tomorrow.
Because I have school tomorrow I am a kid I’m eight years old
Lego steam train pls
No not pistons on the top... on the sides like an old steam engine!
It's very hard to accomplish in this scale, especially since i want it to be able to run on official LEGO tracks.
more power of the motor to function
wow
Centre of gravity too high.
Flywheel too small.
Gearing too high.
Train too short.
Bruh ya need a better engine that one is too small
And it will give is better force and strength and speed
Just build it like a steam engine
