Lego Engines

Tags: ,

I’ve been fiddling around with all sorts of compressed-air engines over the past few years, but these Lego Technic engines by Alex Zorko are really something.   Check out these two examples, an inline 4 cylinder and a V8, each of which goes over 1000 RPMs.  You really can make anything with Legos.  Assembly instructions, parts lists, and live videos of the running engines after the jump.

I just ordered the pneumatic cylinder and switch parts to start fiddling around with these designs over the summer and will report on progress as I go.  In the meantime, start fiddling yourself!

 

Here are the assembly instructions for the inline 4, and the parts list

 

Check out this video of the inline 4 engine running at 1200 RPMs.

Check out this video of the V8 engine running at 1700+ RPMs.

    Are the valves on the inline 4 modified or stock?

    Hi
    I know this is probably a bit of an odd question but do you happen to have the name/part number of the pieces you used for the V8? I have to get the bricks off lego.com and there’s 1470 separate bricks to go though….
    cheers
