Lego vacuum engine 

Thank you very much!

@@MR.OOFofficial always😀

@@MR.OOFofficial Hey so i dont have this what i think is a knuckle arm of some sort but can you tell me the name of the peice that makes the piston turn over please would mean alot

@@Ll-gd9sj hope this is the piece? Technic Engine Crankshaft Center BEIGE (TAN) - (6013937/6355727/2854)

This “supercharged” engine doesn’t do anything the charger is to boost the engine not just spin paddles… The super charger should be atop the valve so that when the valve goes all the way down “letting the piston exhaust escape” and blocking the vacuum to piston chamber, should only the turbo or supercharger blow air into the piston chamber to then push down the piston faster to then pull the valve up faster to then start cycle over again

Yup

AGAIN… ITS NOT HARD TO UNDERSTAND ITS JUST A BELT DRIVEN TURBINE NOT DOING ANYTHING NOT BOOSTING NOT ONE PEICE OF THIS ENGINE MATTER A FACT ITS SLOWING IT DOWN

@@TheLegoPro1234 sorry bro this was a long time ago, I already destroyed this little engine, but this is the video where I got it from, hope this helps. LEGO Vacuum Engine Tutorial - HIGH PERFORMANCE

Mhmm where..?

Yea

I did but i need to sand it down inside

@@MR.OOFofficial Noooo!! do not sand down the sides of the wall near the piston, it will make the two airs collide (bottom and top) in return making it worse plus, you'll need to get more pieces I'm an engineer, and I would know.

@@MR.OOFofficial do you have discord? if so can we talk?

@@FidgetFactory1 no sorry I don’t have it

@@MR.OOFofficial do you have iPhone?

They do kinda have a cold start to them. The plastic contracts after awhile. Once the engine has run for a good bit and has been maxed 2 or 3 times, the plastic gets warm enough do to friction to put less friction on the piston and therefore starts easier.

I have built several different types of vacuum engines and they all need an initial break-in every time you start them

@@LVBeatzMusic this is correct out of every comment on this one video

@@NovaBuilds101 Thankyou. I try to make smart comments when I have experience with whatever it is ;)

I wanted to so bad but I don’t have a Lego battery and electronics

@@MR.OOFofficial Use an inertia starter or a rubber band loaded one. Or if you have it the pull-back motor from the car sets.

It doesn’t even work…

Maybe it’s the housing of your cylinder of parts trying loosening things up, give it some play put some oil inside the engine for it can smoothly go up and down 👍

Just a little bit of oil it can be anything even wd40

To have fun and become and experience the art of engineering

There isn’t
