Lego Flat 2 Engine
Finally, I got an engine working with the Lego fake engine blocks. Leave a comment if you have any suggestions for how to make it faster or have a better seal. I use graphite powder to make it rev faster, like in the second clip, but it doesn’t last very long.
In the future, I hope to make more cylinders, and try the tire valve system in a v4 or v8. So far, the tire valves have been too slow and haven’t had enough power.
