Df's lego engine thread

[dudeface]

Instead of creating a new thread every time I build a new engine, I'm going to post them here and then it doesn't matter if anybody cares or not.

So let's start with this quickly built "OHC"....

And here's my rotary valve opposed piston. I really like this one.

This was one of like 5 lego turbine speed records broken in a week  The guy who broke this one with 21,000 rpm broke his own record a day later with the same turbine at 43,000 rpm. Nobody's broken that yet..

These are some very interesting engines. Are these made of specialty Lego pieces or parts of kits? I have never put Lego together so know absolutely nothing about it apart from Lego Masters on tely.

Lego vacuum engines typically use mostly basic pieces. There aren't any parts specifically for them but the short cranks for Lego fake engines are commonly used. Some people 3d print parts but I think that's cheating. 

This guy, Erin Lassley, is thought to have semi-popularized LVEs though the first known Lego engine was supposedly built by Matthias Wandel in 1985.  https://m.youtube.com/@LazloNQ

I built this engine in April 2023. It's a double acting single cylinder and it was my first working LEGO engine. It hadn't run for a few months and some parts had been taken off it to use on other engines. For its 1st birthday I decided to put it back together and make some improvements to the ports and piston for better performance.

Thank You for the info. I will look around for some bits and pieces.
