LEGO Vacuum Engine Tutorial - HIGH PERFORMANCE

Рет қаралды 611,261

Күн бұрын

A step-by-step, hand-built tutorial for the latest and greatest Lego Vacuum Engine.. My personal design, version 5! Capable of up to 6000+ RPM and lots of power for its size! In this particular design, I optimized the amount of airflow as well as reduced all forms of friction by lubrication. The engine also features a newer 'slide' throttle design which is much more efficient and compact compared to a standard Butterfly Valve throttle. Feedback is always greatly appreciated, so leave a comment!

Also I made a Studio model of this so that people can upload the .io file to BrickLink to automatically create a Wanted List. That way they can order the parts. Someone ordered it today and said it cost them $35 including the shipping. Look for it on the #free-instructions channel on the Discord Server.

I didn’t have all of the parts for this engine so I had to improvise. After hours of mind numbing adjustments I was finally able to get it running at it was so satisfying. Thanks for the video and for people looking to build this, don’t give up! Even if you don’t have all the parts, get creative and use the different parts to get the job done. Only thing you absolutely need the exact same pieces for is all the crankshaft parts. The small 1 and 1/2 pieces are essential for the engine to run and they have to be at a 90 degree angle to the 2 hole cranks on the piston side.

You can very easily replace that piece for a 2 stud long one, you may have to adjust the length of the valve connecting rod but it would definitely work. My first LVE on youtube utilized that crank setup and it worked just fine.

I finally made it. A solid connection DOHV Lego vacuum engine using a 4x4 piston. The base is only studs in length, and six in width. I believe this is going to be the first of this kind on KZfaq. (I inspired it from my other design for the chain driven one) I'll post it sometime soon :D :D. After some research I believe that it might possibly be the fastest of the pushrods ( With consideration that solid connections are like a family of the cam actuated ones).
