It’s 11 at night, My ADHD brain has taken full comtrol and I am now an engineer
Lmaoo😂
only 11?
Same
I’ve had ADHD my whole life and I’m getting my engineering degree now and I’m doing the same thing lmao. Chase that dopamine! 😂
Same lol
Dang! Couldn't have done a better job myself, keep it up bro! I think you've given me a new video idea!
Could you help me with my Lego motor? I have a high suction vacuum, and the motor turns pretty good. It is a single valve single cylinder engine and it seems to start to turn on its own but doesn't take off
@@th3_ap3x_n3rd make sure your timing is right and everything, and make sure everything flows good. Also make sure the valve is working properly.
THANK YOU SO MUCH, I rewatched the tutorial and your basics on vacuum engines, and I got it running. The only thing is the throttle is odd in that it does not increase throttle when I give it more throttle. Any pointers in that?
Production quality is insane! You did a very good job explaining :)
Nailed it. I was pleased to see that the displacement calculation part at the end is on point.
Yes! I have you to thank for helping originally on how to calculate it.
i already built one of his models and it works so well
I’ve come up with an interesting concept for a vacuum engine that I want to try, and it seems logical but idk. My idea is to make a multi-stage vacuum engine, in that the used vacuum from the first cylinder is “recycled” to the next cylinder. My logic behind this is because you need the exhaust stroke, there is still some sort of vacuum left in the cylinder. This means, by my theory, you may still be able to use that second vacuum to make power. Now with my knowledge of steam engines, I propose you may need a larger cylinder to get the same effort from a smaller vacuum power. I need to make a rig to test this but if it works it I’ll be sick af
This is exactly what I needed
Just followed your other previous vids tutorial and i finally got it to work! Cant wait for this vid to drop
Congrats
I can't wait !!!!!
I can
I built an engine similar to this one and its indestructable, I've run it at max rpm for like 5 mins and at idle for like 20 mins with no issues.
LVE’s can be fairly reliable if you build them right, so nice job!
To find the displacement, I just fill up the cylinder with water and calculate the volume of it with a measuring cup, because 1ml=1cc
Can you teach us how to build a vacuum engine, but with a supercharger?
Making a system with gears for the supercharger to rotate more than the engine and thus be able to push air to the piston, making it go down faster and increasing its final rotation
thx from Brazil!
why don't you just use a transmission, it's more fun too :D
Since we are working with vaccum, and not combustion. This would result in a net loss. You could only get energy out of the engine that you put into it via the vaccum. So it wouldn’t really be a supercharger. It would just be more friction
@@coconut_in_a_suit975 a second vacumn
To be honest the only lego vacuum engine I've ever made was a steam engine piston type design, it worked just fine, however, I truly never really properly designed a proper throttle body valve.
I think I'll make one of these and build a clutch + transmission to go along with it
Silicone lubricant can also work! People use it all the time for modding LEGO pneumatic pistons
Yes! I probably should’ve mentioned that in the video. The best type of lubricant is either silicone based or graphite based. I mentioned olive oil or veggie oil since those are much easier to access
I am building one and was wondering if the vacuumed power changes anything?
do you need a two sized stroke engine? or is there a alternative? i dobt have one but me want make dis
I have a question do you need the holes next to the valve
Ok, I have a vacuum engine that has been adjusted for 2 and a half months SPECIFICALLY for available part I own ,and I plan on adding a turbo, yes TURBO and I might record it… so be looking for it.😉
im building my own engines and i have a few questions about vacuum enginges.
So first things first, does the engine need to be free(without oilpan)?
And i have trouble with building intakes. I Always loose the power of my vacuum in the intake.. Do you have tips for that`?
I am thinking of buying the parts for this but the vacuum part a simple vacuum cleaner which takes air in or out
I like that 2 stroke engine 👍
Do you know where you got that wheel?
those 2 pieces at 2:09 can they be 407001 pieces cuz they have holes too but smaller
Where did you get your parts
What kind of vacuum do you use?
I have made a I4 engine and it has a SOHC valve system i am going to lube it because it will improve performance
I have a vacuum engine that doesnt run using a 2x3 piston and a 1x2 valve with the crank being 2 long
The timing is on and everything any idea why it foesnt ru
my gf got me the ducati build for Xmas one year. I wonder if hooking some kind of intake (in this case vacuum) manifold up to it would have a similar effect 🤔 although idk how u could build valves into the cramped space.
dam now I can't stop thinking about it lol. I wonder if u built the valve and throttle assembly separate than ran small hoses to each cylinder head. that'd be dope lol
how do i make a five stroke engine cause o dont have te pieces for the other one
Does the vacuum need to blow out or suck in
i made an big I-4 Engine(without tutorial). I had a look at all rules, what you told me here and it didnt work. Well..is the cause probably the long way from the intake to the piston?
How do you connect the vacuum to it?
do you maybe have a parts list? recently got rid of all my old lego but wanted to try building a custom set myself. Thanks!
Look at his previous video
If you intend to order online check out the parts list file on the Discord server that can be used on BrickLink.
How do you make it run tho?…
Is it possible to make one without the crankshaft center piece for the piston? Every tutorial uses it
Yes just use a 1x2 technic piece (half stud wide and rounded, with axle holes)
What vacuum do you recommend that will give me a lot of power for these engines?
I personally use a Dyson vacuum, but I think the best one for LVE use would be a big shop vacuum, because those have a lot of sucking power.
How do I get the vaccum connected
all my engines keep getting stuck when i try to run them...
it is the vacuum cleaner or what it can be?
i did the valve timing right and it just keeps getting stuck
it needs an exhaust?
Turn it the other way same thing happened to me
Dude, i have another idea, please make video of this exact engine or the original, built side ways, like steam engine, im telling you, no regrets. Also, make video of how to build!
Btw, LOVE YOUR VIDEOS👍🏻! Keep it up bro!
Perhaps in the future I'll make a steam engine replica, I've thought of different designs in recent weeks.
Do need need a big wheel like the one you have, or could you make a wheel with other parts
You can definitely use a different part for the flywheel, as long as it’s enough weight to carry the piston through the stroke it will work fine.
@@KFPlusLegoMastery how much weight should it be?
How would you tune this and wouldn't the friction from gears cause alot of friction making this better for slow high tourque engines?
How to tune would be turning the gears to change the timing of the valve
Surprisingly the 3 gears I use have very little friction. You can also apply the olive oil to the teeth of the gears (looking at it now I probably should’ve shown that in the video)
@@KFPlusLegoMastery hey I finally uploaded that chain driven DOHV LEGO vacuum engine with a four stud bore. I think it’s the first. I’m in the process of modifying but it runs quickly. The showcase is on my channel.
@@KFPlusLegoMastery it took forever to get this one to run
Hey. What length is the valves rod?
I’m using a 5 stud technic beam for the valve.
Hi KFPlus Lego Mastery, I’ve created an engine using the same valve design as this, but whenever I run it over speeds of 1500 rpm it breaks. Is there something I could do to stop this from happening?
Glue
Well if what breaks is the valve, I’d recommend applying a small amount of glue to the valve. Nothing too crazy but it should definitely help a lot
@@KFPlusLegoMastery Thank you, I will try this
The best thing for reusing your parts would be to cut a napkin and place it on the pets you want to connect. This way the parts fit tighter. Then you can just use water to get rid of the excess napkin so there is not extra friction.
What song pls
what song
Where I can buy the LEGO parts I need to build a Vacuum Engine?
We have a downloadable parts file as well as instructions how to order the parts on the Discord server, feel free to check it out!
does the vacuum blow or suck?
It's a vacuum
How do I up the speed. It runs very slowly but very consistently.
Add a throttle
should canola oil work?
Yes! That should work just fine.
I made an engine bases off of your design , however it gets stuck at the top and does fire when i turn the shaft but does not run itself
try lowering or hiring the exhaust valve by one stud
Fuck it I’m gonna make a gas powered Lego engine
Please make a tutorial for this engine
Is it blow or suction? Since I don’t know
Suction, but these engines can run just fine on positive pressure (blowing)
My Piston blew up after lubricating it and running on full throttle cuz I hadn’t glued it I just reinforced it with more pieces lmao. I just glued it though, hopefully it won’t blow up
Update: After making a belt chain from a very old lego Star Wars set. I’m attempting to make a centrifugal supercharger.
Hey! I have a 1 cyl vacuum engine and the valve is causing problems. The friction is crazy!
Use lubrication
i run my vaccum engine without oil but I have found that is what makes it ru nthe fastest. if i use oil it ends up causing the engien to fall apart
One thing i dont get, is why the 1x1 technic blocks are needed
does ur vacuum need to blow air or suck air in?
My engines run on suction, but these engines can actually run on either blow or suck. Suction works better tho, I think
alr thanks KFPlus lego mastery@@KFPlusLegoMastery
Exact situation im in🤣💀
I am building one at the moment, does a one valve one piston engine require a throttle valve?
It doesn’t necessarily require one, and it’s not going to hinder the performance whether or not you add one. It just gives you more control over the speed of the engine without having to move the vacuum nozzle up and down the intake port
Did you build a tutorial for this engine
Yes, I built a similar engine in a tutorial. Feel free to check it out.
butter works too as an lubricant
I like my butter on toast, but I guess that could work too 🤷♂️
Olive Oil is the worst thing to use because it gets Sticky.
11Mins and 11secs٫ perfect
2:20 , technically its not an exaust stroke, its an intake stroke.
hello, is there anyway i could contact u to show u mine to see what i’m doing wrong
You can add me on Discord at KFPlus Lego Mastery#8852
Bro I need to make one but don’t have th parts
You can order parts for cheap on bricklink.com !
2k liker (when i liked it switched to 2k)
I just posted the video
tutorial pls
what makes the popping sound in this engine th-cam.com/video/burbh2C0Ntg/w-d-xo.html
Do tutorial
how do you make my valves so strong
Glue. Not so much that it permanently bonds the legos together, though
glu
Oml mine actually works.
Runs like shit but I can tune jt
That’s my mine wasn’t working my valve was moving with the valve
Instead of using a vacuum, could I litteraly just attack a Lego motor thing on the the bar where the tire is?
It's not that fun
@@fireballyt3676 but it would work right?
@@benwrycraft-jane3783 no it would be really really slow
@@fireballyt3676 what if I get like 10 of them and make a gear thing that ups the rpm
How bad can wd40 damage your lego's?
It won’t damage the plastic unless you leave it on the legos for a long period of time. Whenever you deconstruct an engine make sure you clean off the WD-40
wd40 is some pretty caustic stuff. its a lubricant but also has some solvents and other crap in there. over time that can eat away at materials its not intended to be used with.
lol
Come back :(
idk how you do this he a real hacker
So we’re did bro disappear off to it’s been 3 years
my vacum cleaner died:(
his overheated
I built a buggy
my vuucum cleaner sucks
As it should
Is there not a need for timing on this? I’m completely ignorant to all this. I just seen you on tik tok?
Ok never mind you touched on it in the video.
