Building and testing a LEGO Pneumatic Engine (V2)

In this video i will build another LEGO pneumatic engine. A pneumatic engine is a engine that runs on air. If you enjoyed, i would really appreciate if you subscribed for more upcoming videos :)

what size for the hose?

You’ll get less shaking if you put the valve crank eccentric to the piston crank

Sorry I didn't get ur comment are you saying that the valve and piston share 1 crank pin or smth? Can u explain?

[@jamesgroccia644]

@@ThomasthetankengineE2 I mean the crank for the piston and the crank for the valve are in sync. That leads to a lot of shaking.
If the valve and piston cranks were opposed and still in phase, that too would result in shaking - as well as the piston itself not being as efficient.
If the valve crank were 90° ahead or behind the piston crank, there'd be much less shaking because the piston isn't getting back pressure (airflow into the wrong end). The smoother the engine turns, the less shaking.

​@jamesgroccia644 oh ok thanks for clarification sorry for misunderstanding if you pause the video at 1:23 you can see that the valve is 90° behind the piston crank
