This is a MOC ( My Own Creation )
I did some RPM testing after the video too, and i got over 3000 RPM!
You can also use the new type of Pneumatic switch, have a look below.
➤ This engine will only work using the v2 small cylinders, i have used a normal one but i recommend using the newer type. Follow my guide for modifying this part and the switch - • How To Modify Series
➤ Converting it to the New type of switch - plus.google.co...
At 1:37 it should say RPM not PRM, just a small spelling error sorry.
if you can find a smaller LPE that uses a pneumatic cylinder, comment below and i will have a look...
➤ Parts list - rebrickable.co...
➤ Both switch and cylinder were modified, this engine will not run without these parts modded.

I did some testing after the video and i got over 3000 RPM out of it. i recommend using the newer v2 style cylinders. they have the correct amount of stroke (3 studs), while the older type has 2.75 studs stroke. You also can use the new style of switch, read description above.
How do I hook up my air compressor to it? I can't seem to get it to work.
I have a quick question, the engine is quick but is it also strong? I thought that maybe pneumatic engines would be a better solution for my project since the normal motors get weak very quickly ad for them to be quick you also need gears which again make it eve weaker.
Goggle plus no longer works for that sort of stuff

Teppo Multimäki wow someone should’ve made a joke about that
@@cadenthecadburyengine8198 what an idea, why didnt i think of that
@@teppomultimaki1074🤓
put graphite powder on the moving parts , it reduce friction
i will look into that, do you recommend any brand? Thanks

*Looks at it closer*
Ohh... That's easy
that was the idea
This sounds so cool
Thanks
It needs a larger flywheel then you could get some more rpm out of it.
No, bigger flywheels lower RPM
@@smallenginesgarage7168 But still that's too small
Yeah the heavier flywheel would definitely make the engine run smoother
I built this with all the new parts but it still won’t turn over. I also followed your how to turn a 2 liter and make it an air holder. It won’t run and I wanted to know any way I could fix it. (I re-did the cam and it still won’t work.)
i have a new camera setup now, Nikon d5600 and the Rode videomicro. also, i am using a backdrop and a softbox.
Green Gecko Lego Technic Creations someone made a smaller engine with a large cylinder but it wasn't nearly as good as this
i think i know the one, i have built that engine before. it needs a big flywheel for it to work, once you put the flywheel on it becomes much bigger than this. my engine is still smaller
read description, updated version
Does this run with the Lego spring loaded pump?
no, off a air tank (non lego)
It works!Thank you so much Green Gecko!👍👍👍👍
Awesome!
Awesome! I never have been able to get a small cylinder engine working, may have to try this!
thank, the cylinder must me modded. its very easy and i will do a video on it.
@@GreenGeckoLegoTechnicWorkshop i drilled mine to 1.5mm with my hand and it works. i tested mine with an unmodded switch and they are perfect for an LPE
this sound!! awesome :D
thank you
Tx
At 50 PSI that thing is strong!!! You can just hear it!
Help! I built this with the new switch and v2 cylinders and when i pump air into it the pump stalls and wont turn
Any ideas for a fix ?
Might need a higher pressure pump to run it :(
make sure timing is correct on the cam for the switch. also the switch and cylinder need to be modded ( drilled to 1.5mm )
Oh i have several pneumatic switchs so i could yeah thanks !
may sound like a tad of a dumb question, but where does that pipe run to, is it some sort of mechanical pump that runs it? Thanks :)
Oliver Russell pretty sure it runs to a compressor to give the engine pressure
Google+ doesn’t exist any more so can you make a video with the tutorial with the v2 switch
ruclips.net/video/vaRLDdkt2Yo/видео.html
wow It's a pretty smart idea, compact and small, I look forward to see it in a car, well done!
Thanks
Now make a LEGO lawnmower with this engine ;)
nice idea
Now put that engine in a truck
i built it with the new switch and it sounds amazing at 100 psi
do you have a video or a tutorial to build it with the new switch? google plus dosent work anymore so i cant access it
@@somerandomdomino ruclips.net/video/vaRLDdkt2Yo/видео.html
MAN THAT SOUNDS GOOD
thanks
Sounds like my dads 1996 buick skylark
So much inspiration from you thanks !!
Thank you
When I saw a preview, I thought what it's a portal hub)
I love your dampings! 🤣😂
music loud
I don't have the 6 pin half wheel and mine won't work
Okay, you need to use the Wedge wheel for the engine timing. Then it will work. You also need to use a Modified Pneumatic Cylinder and Switch. We sell them on our store here: www.greengeckoworkshop.com
Hello it's me again... Google + is down for good do you have a bricklink for the new switch or should I not bother you at 10:33 and buy a old one
What are the most important pieces in building engines should i buy off bricklink?
Ok this is cool :O
what’s the long pipe that go off the camera for every video doesn’t show that one now to get the psi
That's from the air compressor, it powers the engine.
I made it , ot has good torque. If you have new switch i will show modification to make to make it fit on my channel
Great vid
Great work first off! How much torque does this have compared with the normal cylinders (considering how much less air they need?) Eg; is it more worth creating an engine with a lot of these little cylinders (perhaps a V8 etc, i think by the math - the standard ones are 9x bigger and have 4x the force output so it may have to be a V12...) or an I3 with standard ones if they were run off the same pressure and air flow rate?
And how do you get these modified switches - every time I've tried doing it myself with the new switches but they don't hold the pressure afterwards...(And I've never been able to get a hold of these older style switches either)
And is it also possible to make a video on how you time your engines? I can always create the mechanics but never figure out the timing well enough to run smooth (doesn't help I'm still trying with unmodified switches but I can modify cylinders).
Any thoughts? (Sorry for the lot of questions...I'm thinking about making a vehicle with an LPE in it...)
Jack Taylor I
Hi,
This engine doenst make a huge amount of torque, but it has a little bit. i am planing to make a i4 or i3 engine with these cylinders, and it will have a lot more torque.
Great idea for doing a video on the timing, will have to do a LPE mechanics series then. stay tuned.
To get modded switches you must modify them, i will do a video on that too. have a look on my About area on my channel there is a bit more info there
Thanks
So compact :)
Is this legit also where does the air go through and where does it go out? Can you show
How did you put the pressure on it?
Btw super cool thing!!!
air compresser
What if you don't have the valve in the video and have a different one
Remember my last comment you couldn't understand? It was this I meant! :D thanks
i don't remember
Have you tried using an heavier flywheel??
Yes, it didn't help much and made it unnecessary larger
Does it have alot of torque or isit easily stopped when you toich it
It has decent torque for its size
Please tell me what hoses are those I wanna get them?
You can buy them on my store - www.greengeckoworkshop.com/
idk if thats actually going 2200 rpm in the vid, he could have easily added 2 pieces of reflective tape on the wheel to double speed reading
I just used one piece, you can build it and test it yourself if you wanted to check.
How do you power it?
Ait
First of all, great video, nice engine. But you got your volume gained way too high, i'm listening on the lowest possible setting on my phone and it's still too loud! Definitly something to work on!
thanks, will decrease the volume a bit. thanks for telling me
I suggest to turn down the music volume or delete it completely. The rest is perfect.
Does the old small cylinder work with this? I saw som vids where the old cylinder also had a stroke of 3 studs. I dont know what is True now...
No, the old cylinder has a stroke of 2.75 Studs. You must use the new one with 3 studs.
@@GreenGeckoLegoTechnicWorkshop but you used the old cylinder, and it worked?
What is the source of air supply in your pneumatic applications?
Check out the Custom Air Tank video, i use a air tank at 55psi to power my LPE's
THANKS GREEN GECKO! I made mine out of the video but i used standard small 2L cams as a substitute for the Cheap wheel rim.
Edit: I also used the 42008 valves as another substitute for the 80s valve. And it works like with the one in the video!
Awesome! Glad you liked it
@@GreenGeckoLegoTechnicWorkshop no problem. but how much psi needed to run (minimum)? i used a gray lego small compressing pump and the engine nearly ran by itself
Just ordered the parts to make this please sell it on your store also can you upload how to upgrade to the new valve Google+ died
How do i convert it to be used with the new switch? The google+ link doesnt work
I can send you some photos
@@GreenGeckoLegoTechnicWorkshop please it doesnt work i need the new switch conversion im trying to make it with non modified parts i have the old cylinder but only new switch link pictures here
I have both new parts but not old switch
@@GreenGeckoLegoTechnicWorkshop and also is there any way to make this with non modified parts?
Is there any other pieces I can use instead of the switch
No, The Switch must be used. You can purchase them on my website here : www.greengeckoworkshop.com/
can you make an engine where the cylinders don't move
Work without modified parts too 😉
But need a little bit bigger flywheel
if you've never drilled out the ports on your cylinders you could get more flow/speed that way.
I drill the ports out to 1.9mm or 1.5mm, Depending on the Engine
maybe try adding a larger flywheel to reduce vibration?
That is sick o:
thanks
I have all the parts besides the switch. I have a switch with two holes on the bottom of the switch how would I mound this? I can't figure it out
i made a guide to use the newer type on my google +, have a look in the description in this video. thanks
replace the 9l with a 7l and attach another 7l and two pin and pinhole connectors (1 stud lower from the highest pinhole)
What’s the music called?
Which music is in the Background
You use 4mm x 2.5mm tubing right??
ay yo whats the torque in kg?? can it pull a hooman?
That's quick same speed as my engine
Can i make this without modifying the cylinder?
read discription
incredible design but how reliable is it becuse at the start i saw it was a bit difficult to get running?
Very reliable and simple engine, it does this because its a 1 cylinder. once it gets going it is perfect
Did you modify the tap?
Yes, it is called the switch.
Work with 20 PSI ?
I made that and is not seeming to work I modded the parts what do you think the problem is?
check the motor timing, did you use the v2 version of the cylinder? you can still use the older small cylinder but it requires a modded the seal.
Green Gecko Lego Technic Workshop the timing is exactly how your is and yes I am using the version two cylinder I think how do you know? I'm using the new switches as well maybe I didn't mod it right. I never put lubricant in them but I'm not sure how much that would affect it
did you follow my mod guide videos?
Green Gecko Lego Technic Workshop yes
Do you need to press much air to run it that hard?
around 50 psi, from a air tank.
What if i replace it with big cylinder
It will still work
Do you use clue with those pipes
What type of pump are u using
JLiu15’s Lego Studio its an air compressor
Would this work nonmodified?
no sorry
It will work, just won't be very fast. You'll have to change the flywheel though. Put a big gear on the crank where the tire is in the video, then connect it to a small gear with a big wheel
I have seen smaller. But it is pretty cool.
where?
Green Gecko Lego Technic Creations m.ruclips.net/video/Gk5xFfNCvi0/видео.html
This engine does not work, i have talked to the guy and told him he needs a switching mechanism. Thanks
Green Gecko Lego Technic Creations I have seen some of his that have worked. Just check out his videos a bit more.
i have seen all his videos, none of them are smaller than this, anyway they are not using Lego pneumatic cylinders, but highly modified lego fake engine parts. they are still pneumatic engines, but of a different kind.
Is the switch modified?
Yes, they can be purchased modified here: www.greengeckoworkshop.com/pneumatic-parts/
Needs a bigger flywheel to run smoother
At 1:32 you said 2200-2100 prm, I think you meant rpm;) great video by the way
read description
Ah, okay sorry my fault
Does it run with unmodified parts?
NO
What do you use as airtanks?
Soda Bottles, Check out some of my other videos
Do a compact I2 engine
Can you make a tutorial for non modified parts? I dont want to destroy mine.
i have other engines which are non modified
You could.... start a jet engine with that power.
Can one make this with the thicc pneumatic?
Yes, I already have...
@@GreenGeckoLegoTechnicWorkshop yeah ive seen it and it looks really good... i commented before looking
I have everything but the specific type of switch required
You can get them on bricklink.com
can this work with ver. 2 switch
yea you just have to modifidy it slightly
Where can i find air pipe?
check the about area on my channel, theres a ebay link in there
Not working
Mine isn't working can't figure out why
check the timing and the description please
Make sure the retainers aren't too tight against the cylinder.
It sounds like a drilling machine
Connect a lego air compressor to the engine to have a free energy engine
There's no such thing as FREE ENERG
Looks great - would you consider adding this version as a mochub? (I see you’ve done the other version - which looks great.)
thank you, yes that sounds like a great idea. i will do that. you do need to modify the pneumatic parts for air flow increase. i have a video on that.
Cool - I saw the video on modifying the parts. I'm interested in the mochub entry.
thanks, i will get the listing on this week
Engine turns compressor and compressor feeds the engine
Can it be made with the newer switch?
yes, i will post a photo on my google + on how to do that.
Green Gecko Lego Technic Creations ok thanks :)
look in the description
done
I won't do it if I have to spoil my cylinder and switch
modding does not spoil it, it makes it better.
But that mod only works for this creation
there will be future builds with the small cylinders, a small v8 is coming soon
Fajne 😀😀
I could make this if I had all the needed parts
IT doesn't works :'(
install it o a car and make test ;)
could do
@@GreenGeckoLegoTechnicWorkshop yo could u remake with the newer switches
Try 6 bar
Я всё собрал ,но не работает ,а воздух ты как качал? Russian
Jaka to muzyka
This switch is still working?
Yes, i have modded it to decrease friction and increased air flow. i have a mod guide for doing this.
@@GreenGeckoLegoTechnicWorkshop Can u make video about it? It can be short video ;) Btw. i subscribed and liked ;)
Ouh. Sorry i was thinking you have it on paper or a private video etc. Sorry for that xD
i have made a video on modding lego pneumatics, i am releasing a new mod guide series tomorrow as well. stay tuned
@Green Gecko Lego Technic Workshop .Okay ;) Thanks but can be use normal switch and normal piston?
