Air Engine

[endrachwer]

why the hell du you have that wheel derect on to the crankarm!!!! you need too gear it upp or something!!! it freaking stops!! and it will not help having more presure!!

[TopARO]

Dude, calm down. No need to be pissy. It was my first version. And do you know how little weight legos make for a two cylnder like this? Is it that much of a problem to you?

[shortizahn]

@TopARO you should still add a clutch oO

[iannGT2]

@TopARO well yea what the crankarm is sort of pointless. anyway, if you use a bigger cranckarm for the wheel, and increase the length of the piston rod it will turn smoother. oh and get rid of that pointless crackarm, its not the weight, its the friction and stuff that slows down the whole system.

[Pacerace100]

@endrachwer Its stopping due to the design of the switch valve. The new lego switches are 3 way, and in the center location the air flow is stopped. Its better to modify the switch, or use the old style 2 ways for the pneumatic engine.

[endrachwer]

see i wrotw that!

[the777brian]

wrong name for video should had been engine made from lego

[legomindstorm1]

is good...but video is not good!:::

[headhunta36s]

cool

[TTandN]

hey, i built a dvice like yours but i didnt put a wheel in the center. and i was wondering if you could help me, i will leave a vid as a video response show what goes wrong with mine

[TopARO]

Sure!

[zark76820]

WTF THIS IS JUST LEGO LOL

[TopARO]

It's that simple.

[linkfan770]

maybe if you switch the hand pump with something a bit more... uh... pressurized?

like my dads air-pump. you charge it, and shoot it like a gun. you use it to fill tires with air usually, but i bet it would work here

[TopARO]

That's what Im doing with my newer engines. I have a tire pump that puts out tons more air than this one.

[FrontalTraction]

I made one similar to this but with the "new" technic. (It's on my channel.)

[redyou65]

it gets slow at one point

[TopARO]

I know. All I have is a stupid hand pump. Not easy to keep pressure up.

[Helge129]

Then power the pump by electro motor :P

[TopARO]

THe lego ones aren't powerful enough. I'll have to find a small compressor.

[Helge129]

They are powerfull enough, if you use gears with them, but then, they become kind of slow :/

[TopARO]

Then there's not enough air flow to sustain the engine.

[Helge129]

Link several pumps and let those then go into a air pressure tank (yeah. there are some from lego), and that pressure tank to the engine :P

[HaloArchive]

Nice angine...C.S. Cosh's engine though is VERY inefficent...When you try to run ti on compressed air, it has a tendancy to lock up and stop working :o For this..i say that even a 1 cylinder engine is better :D

[TopARO]

to slow for 1 cylnder

[Kiti2007jordan]

I just buit this engine but unfortunately I don't have the 2 and a half long links so it doesn't work too nice but I've added 2 rubbers to pull the switches and it dooesn't block any more. Try this!

[davetheguy88]

tip: try to get the engine to switch the air valve on its own, like a steam engine does, make a lego compressor too to give a contiuous airflow to the pneumatic pistons, very nice model too

[TopARO]

It does swich on its own. Not enough pressure to make it go any faster.

[petem1989]

If you can get hold of 4 of the old style pneumatic cylinders (the single acting type) it will run smoother and faster. The double acting ones arent as strong on retraction as extension.

[TopARO]

Ya, never seen the older ones. These are slow.

[petem1989]

Try on bricklink You can sometimes find the old pneumatics on there

[shamushand]

Nicely done!
