Lego Pneumatic Engine V4 switchless (2500rpm) LPE-DIHC

[lenejam19]

I can hear the engine roar...

[Catz0125]

How do the valves work? Are they little pressure plates that squeeze the tube shut?

[thehappyapplecrew]

how can it be switchless? how does that work?!!!

[SuweraGER]

@thehappyapplecrew Uff... , I realy tried to help the people understand it. Some understand it with out help, some are... well not technically gifted (and many are noobs). But Im serious, heres my last deal: -if this comment get 50 tumbs up from people who are interessted in it and still dont get it after reading descriptions and may searching for other videos like this, I will make an animation video explaining everything, based on Littlebigplanet 2. OKAY!

[thehappyapplecrew]

@SuweraGER Well anyway the engine is cool!

[Imprexer]

sounds like a wrx doesnt it?

[Griffin0663]

Wow amazing, i am totaly amazed, just wow ;D

[Pippomone]

1:04 - Speed is fucking pumping into its veins!!

[timsau]

wouldn't some of the pieces start to melt from the friction?

[josuemorgan]

Fantastic! Please: a pneumatic diagram!

[SMGJohn]

At first it sounds like a vintage airplane and then at 2500RPM it sounds like a generator

[nodytota1]

at 0:33 that really blowed me up......... 7 words A-W-E-S-O-M-E

[Zblj1987]

Nice concept!

[BOREDfromX2z]

can it hit 3000 rpm ?

[clowj69]

sounds like an old pony car

[Enve669]

Sounds like my old Ford Transit MK4 2.5 TDI. I LOVE IT!

[COMPUTERMAN5668]

were do you get these???

[niels125521]

hey, I really like your concept, could you provide instructions for it? it doensn't need to be the whole thing, just a part like 1 cylinder pair is good. I would like to put your concept into a working v8.

i habe built a few fast LPE's, but this concept gives me a lot of questions. i think i understand the concept, but how to built it and make it perfectly run, thats the hard part :)

[emomotorgeek]

sounds like the VW flat four.

[jbrun009]

I need to try this out, seeing as I've ruined most of my switches trying to modify them

[ChuffChuffWoo]

Lets hace a video of it just on tick over! (thumbs up if you agree!)

[astaschak]

put a tranny up to it. I wanna hear it shift (: 

[luuclucas]

Power a car with it

[stophl007]

so glad my parents bought me tons of legos instead of a dumb and uninspiring playstation or something ilke that. 

[RockKing12345678]

how do you connect the cylinders? like what is the pattern?

[monstrum467]

awesome!!!!!! sounds like a real engine :D

[SolarAlliance]

Put that into a vehicle :)

[sobicodamian]

inentendible..



[stezzacat]

can you please sned me instructions?

[13Anko]

The sound is just amazing!

[avatarfan05]

Are you using the coke bottle as an air holding tank?

[hmhmhm4321]

are these for sale?

[Mansharky]

How much?

[SuweraGER]

@Mansharky Wat huw much?!.... I just know that a normal chiken lays around 250 eggs a year, does that answer your question?

[Griffin0663]

i am amazed, i couldnt for my life think that you actually could run a pneumatic engine without using switches. this is life changing for me thanks alot man!

[raymondyemm]

can you make instructions on how to make it please thanks

[kryptication]

Lovely concept! Seems to run much cleaner than any with switches. Slightly miffed as to how it runs though - on a switched LPE, when the piston contracts, the air inside the cylinder is forced out the bottom inlet and the switch allows it to escape into the room. But with this switchless LPE, how does that work? Do you have an exhaust port somewhere? Is that what the tube on the bottom left is for?

[SuweraGER]

@kryptication Basic is a two stroke engine. One tube is the inlet goes into the cylinder, one is the outlet goes out of the cylinder. Description: ... -outlet valve closes -inlet valve opens -air gets into the cylinder and push the piston > air cant escape into the exhaust, because outlet valve is closed! -piston is forced to move down -inlet valve closes > no more air gets into the cylinder! -outlet valve opens -piston can move back up and pushes the air thru outlet into the exhauste. ...

@SuweraGER

doesn't that mean you've had to modify the cylinders so that the inlet and outlet ports are both at the base of the cylinder?

It is an ingenious solution to overcoming the frictional losses associated with the switches.

[mc12spyder]

please post a link with pictures of how the valve/switch less system works! this is amazing!

[mylegocomua]

Very great sound, but I think his power is not enough to pull 3-4 kg lego model. Or am i wrong?)

[WpA09]

so it's basically just cutting off the air flow into a cylinder to get air into another one?

[WpA09]

how do you manage to make it switchlöess?? please respond

[DrDudeNL]

Gorgeous! Great sound :-) And great concept, of course. Good idea to connect the chambers this way. Did I mention that I love the sound of it? I wish I had a 6 bar compressor. Time to start saving, I guess :-)

[TheNinjanevin]

nice
