Butterfly Lego Vacuum Engine Tutorial!

[@smallenginesgarage7168]

You did it! You completed the challenge

[@smallenginesgarage7168]

Im also building it I dont care

[@Jesus_Christ_loves_you_alot]

"It blew up" Piston just straight up falls out lol

[@alejandroacevedo9961]

really good engine, i dont have enougth pieces to meke the valve so thanks by making this video :)

[@forensic5032]

I remember at some point I made a 2 cylinder version of this engine and made the engine base with more ports for the exhaust and it ran great

[@bigmac2909]

I dont have the yellow lift arms but i used the one with 2 holes that are straight And my piston has 3 top Holes so my Blocks have i used 3 1x4

[@antonykarlssonsalmon9145]

Thank you I spent so long trying to figure out how to build a vacuum engine

[@AnthonyMichael-vq7ez]

What prices make the piston go up and down and where do you get them

[@alejandroacevedo9961]

pls, can you tell me what hapens to my engine if isn't works? bcs the engine dnt work, but don't matters if din't work, if not for your effort and your determination

[@Wojciechwrzalik]

Where are you guys getting these big lego walls from

[@JackVac_joeblower]

3d printing.

[@jlbgamez6134]

Mine just locks up with only 1 hole for the intake… any ideas???

[@bigal1774]

How do you start it I can’t get it started and I’m trying to spin the wheel but it just won’t start

[@JackVac_joeblower]

Hi, I've built with a 4 stud high liftarm. It works but, it is shaking a lot, it seems like the piston head was hitting the small little gaps beetween blocks cause I had to build it with block cause I don't have the big walls. I've sandle the corners on the piston heads and lubrificated it. Still can not get it to rev higher that 500rpm. Could you give me tips?

[@KFPlusLegoMastery]

I would say to raise up the walls and make it with a longer connecting rod. the shorter rod means there’s more force against the cylinder walls and more friction. In my experience, a longer con-rod makes a very smooth and fast engine.

[@JackVac_joeblower]

Thanks @KFPlusLegoMastery I'll try it, I've still managed tho to make it run to aproximatively 3500 rpm by putting a smaller flywheel and changing the side of the intake.

[@ccricar]

Woah! So simple!

[@thestreetlightchannel3945]

If u dont want to glue it i recommend to make some rpm first and then fully put on the vacuum hose

[@yaboywynstan808steve_lj6]

Hey could you make another tutorial showing the parts that you would need as you build it please and thank you

[@alejandroacevedo9961]

the engine worked :)

[@dominikvarholik7519]

what to do when u dont have the parts to make the piston?

[@cessnafun5385]

You can’t make it. You could of course figure out a solution by using other pieces.

[@CREWOFPREWAX]

Thanks for the tutorial!

[@BrickMasterBuilds4522]

Mine didn't work I have all the parts and built it correctly thr vacuume made it so hard for it to rotate it was like near impossible to spin it what fo I do to fix it?

[@patateyoutubeuse]

I’m actually surprised it works thx for the tutorial I just finished

[@themechbuilder6171]

why did you delete the original video?

[@KFPlusLegoMastery]

Forgot to add music. Would’ve been boring and less exciting with the silent building session

[@alexismartin1139]

Does it matter on what you use for the crank?

[@messierobjectm1]

how dose the piston go up and down mine just goes up and dose nothing

[@supersimi5276]

Yeah same

[@gavinwhite120]

Can you use a different flywheel

[@lukastomlinson3033]

How do you get it running, mine is too stiff

[@thatyoutoubekid8260]

It stays together but the piston wont move i did everything like you said with the same parts and still doesent work

[@jlbgamez6134]

same

[@wolkan260]

do you need a tire that big or can you use any tire?

[@KFPlusLegoMastery]

You probably want a decent size flywheel, considering the piston constantly has a force pulling up on it (albeit not very much when it’s going down in the stroke) You want something that can easily and smoothly carry it through that cycle. Nothing too small, pretty much

[@wolkan260]

@@KFPlusLegoMastery alright thanks!

[@RK66-RK66]

Help please my piston doesn’t go down again

[@DerMopedGuru]

Mine too 😢

[@Mcneds]

You need to start it partially

[@littlegenius08]

Nice

[@filipn4946]

1:10 what's that yellow part? Please name it.

[@Mcneds]

Comes from engines in technic sets

[@Ll-gd9sj]

Hey kf can you please tell me if there's any substitute or what the block name is for the bottom part of the piston because I don't have that and I do not know what that arm piece is called

[@winetaster-i1x]

mine doesnt run i am using the 60287 rear wheel as the fly wheel does anyone know why?

[@EDP667]

YES

[@XDMBossMan]

How do I get all the parts?

[@mattemotionaldamage586]

i made an performance piston for it and an inline 3 and 4.the inline 3 was idling at pretty much vacuum already and were i think at 1000 rpm max.; the inline 4 doesnt at least get 500 rpm i think. Do you know why?

[@BoskoRLonTwitch]

I keep getting low rpm but when I increase my vacuum cleaner power it stops

[@cpl_legend2700]

You need smal pistol my bad I vacuum my lago

[@cpl_legend2700]

Oops

[@HAMMERTIMEBUILDS]

Can you make a tutorial for it with a carb to change the speed?

[@dirtbikinglucas]

Go to the single piston with valve tut and it will show you how to make one

[@Polobear33]

The vacuum has suffered enough😂

[@carl-2023]

I made the same one and it's not working do you have any suggestions

[@alejandroacevedo9961]

le's see if this engine works :)

[@Alexsshittyelectricals]

Can you pls tell me what size of wheel you use for a flywheel? And can I have a parts list for the 1 cylinder LVE?

[@bricknplay]

What are you using for thumbnails I am using LightX

[@smallenginesgarage7168]

I think I will also do a tutorial for a butterfly engine, I will make a thumbnaul

[@KFPlusLegoMastery]

I use a combination of a bunch of apps on my phone, including Background Eraser, Photo Leap, and Phonto. They’re all free apps and the basic features are fairly decent.

[@elputinlegomastery8054]

Oh hi brick n play 😂😂😎😎

[@BoskoRLonTwitch]

I’ve built it and it is popping but not running do u know why??

[@KFPlusLegoMastery]

The piston is very prone to breaking, which is why I recommend gluing it together. You don’t need anything too strong, and you can always pull apart and clean off the glue when you’re done with the engine

[@BoskoRLonTwitch]

@@KFPlusLegoMastery the piston is fine it just won’t start

[@EthanAdey]

Again?

[@FoxSock]

im trying to make one of these but its jank cuz i dont have the "right" parts

[@Carburator_Ranger]

Mine doesn’t work, the piston only goes up. I double checked everything, and I built it to an exact replica of what the video said. Can someone help please?

[@matthewpagels7247]

I had the same issue

[@KFPlusLegoMastery]

Normally these engines don't start up on their own. Did you try turning the flywheel over manually? If you build everything correctly it should spin right up with a little help.

[@Carburator_Ranger]

@@KFPlusLegoMastery yes, I tried turning it manually. Can the vacuum be too powerful?

[@KFPlusLegoMastery]

It’s possible your vacuum could be too powerful. If you haven’t already, try to start it without the whole vacuum nozzle over the intake but rather only a small portion of it. It should help the engine start up and then you can rev it up

[@jlbgamez6134]

Did you get it working??? ive got the same issue

[@JimmyTheJimmy]

Could you make a tutorial that actually shows you how to make it

[@KFPlusLegoMastery]

What do you mean? This shows step by step how to make the engine

[@JimmyTheJimmy]

@@KFPlusLegoMastery yes but can you show the structure and the mechanism and how it works not just showing an engine because that doesn’t help anyone

[@KFPlusLegoMastery]

Oh so you mean like explain how it works?

[@Neblixfn]

Bro my vacuum is too powerful it won’t start it just pull and hold it

[@kola544]

i wonder if I can make a two-cylinder out of this idea.

[@KFPlusLegoMastery]

It’s certainly possible!

[@mattemotionaldamage586]

I built one like that with some changes and it runs so fast! But it needs much vacuum to idle. Thats the only one problem

[@josephcreedmore4005]

Does putting olive oil on your engine damage the vacuum

[@KFPlusLegoMastery]

It shouldn’t be too much of an issue unless you literally drown your engine in oil

[@a_sheeeep]

I added a throttle to this and wow

[@anton3568]

How

[@a_sheeeep]

@@anton3568 there are different tutorials. The basic idea is to limit the air flow at the start then allow more or less air through

It’s really the genius of this design, where the piston _is_ the valve! There are many different piston designs that would allow for more tilt and more seal, but this particular style worked the best for me.
