Compressed air motor #2

[atomrocketcar]

put that motor on a mini bike, and connect th3 hose to an air supply, such as rider's mouth

breath into tube and it will push the bike forward, if speed is what you're looking for, consider turbo charging it by adding an additional hose connect it to riders ass, is free and fun for all ages.

the only downside is, the bike will never reach full commerical production because most people are too close minded, maybe in india or china we may see them emerge soon

[GreeseMonkeyy]

@atomrocketcar HAHAHA your so funny!!!!! i cant stop laughing!!! if you would read the description you would understand that i was just doin this for fun and obviouslly its not gunna be used for anything it was just a fun thing to do on a boring afternoon

[htomerif]

Seems to me this thing would get cold during operation.  Does it? or does it not really run long enough.

[nissanskyliner34stun]

would drilling a 2 inch by 1 inch hole where the piston reaches the bottom, on 2 4 stroke engines. and taking out the cam and piston rings then having the 2 motors pistons going up and down in opposite directions. only problem i can think of is the pistons geting stuck in the middle of the cycle.

[dmirti1993]

how does that work without a solenoid valve?

[seelder]

how did u do that? thats a 2 stroke right? how did yo u do that without it just going back and forth?

[TePupaTati]

guys, why would you keep modifying combustion engine to air engine if you have no way to produce compressed air by an attached device to the motor? a smart thing is to try find a way to compress air ... i know most of you will say this is not possible but i am sure that can be done. one of the option is: once tha crank shaft is spinning, it will produce electricity wich you can use it to compress air and you will have an air compressed device atached to your engine... how's that?

[sledsandtrucks]

@TePupaTati

The laws of thermodynamics say no-

You cannot get more energy out of a process than is put in, and there are always frictional losses. 

[fairyheli2]

bash valve??

[thinker58]

The condenced air you see as water coming out of the area on the first part of the video where u put the muffler on. That muffler would rot off or become so corroded that it wont work at all. Put a air/water seperater before your motor. lol'

I didnt mean to sound rude at all in this either, just a word of advice! Looks good tho

[clackdwack]

no lubrication

[skutits69]

that is nice with the 2stroke......You do not lose your power like with the converted 4stoke engines with air

[leomarre]

the engine in not really running it's only alternate turning rigth and left

[sideshow45]

ewwwwwwww muffler.

[luckyPh101]

You need a solenoid valve and a reed switch use existing magnet on flywheel just position the switch where it activates valve right as the piston heads down this will make your air moter rum much more efficient

[racer4560]

Pretty Cool good job!

[MaximusMountain]

so how many psi is it? would 300 be enough to power a push bike lets say?

[GreeseMonkeyy]

@MaximusMountain doubt it, to make an air powered bike it would be good to get an air powered power tool and use that as the motor

[walkingfreak]

@MaximusMountain you could probably create something that re generates the air back into the tank to slow you down haha

[airbusA5000]

@MaximusMountain 300 psi would be enough to power a bicycle no doubt at all, ive made a air engine similar to this one, and it needs a minimum of 18 psi to operate, i have only had 130 psi because of the way the valves are situated any more and it would hold them open, if you could put 300 psi into the engine with out it exploding or rupturing that would be probably equivalent to about 50 cc+ engine im guessing.

[aForkandaSpoon]

@MaximusMountain 300 would be more than enough depending on the engine. The bigger the piston the more force on it, so lets say you piston is one square inch. You have 300 pounds of force. Now double the radius (I am doing this because it shows more how quickly power increases with size) now you have 4 square inches and 1200 pounds of force with a piston 2 inches across. Now calculate it for 2 pistons if you get a V-twin. 2400 lbs is plenty, thats over a ton

[athlonz2007]

since this is a 2 stroke, do you need lubricant added to the air??

[bikercc]

what kind of question is that, were not creating any combustion here...the only thing would be maybe to protect the crank bearings or piston rings? but not to help the motor to turn, just to keep it maintaned

[cobraman897]

oil?

[imsofly74]

so thats gay

[TheBattleWagon]

Should try it with one of the cheap bicycle engine kit's from ebay.

[mop6wewe]

Put the carb on so It will pull in gas still allowing the the motor to be Oiled so it will not seize

[bf2chinesedingdoo]

sooo...ALL you did is presurize the sparkplug hole and thats IT?!!! SOOO AMAZING!! Is this just a normal 2 stroke engine with no reed valve?? Please make an instructional video if posibe plzzz!!!!

[ScaniaFung]

how much power it have?

[GreeseMonkeyy]

not much, but itll break your finger if its running at full rpm

[adamtreyhyatt]

how many psi do you have?

[GreeseMonkeyy]

barelly any haha

[the1stbuilder65]

@GreeseMonkeyy what did you do to that engine in order to make it run off of compressed air? i didn't see a valve in the video, did you do anything other than put compressed air in it?

[MazdaArai]

nice , whats it gonna be used for

[GreeseMonkeyy]

nothin really its just fun to watch it idle and see it workin

[jaws87]

USES NONE WAT A WASTE OF TIME. unless u plan to carry a 1 million gallon reciver tank

[strantor]

pretty cool. have you tried hooking it up to a load? could it power a small generator? how fast doe it drain your air tank?

[GreeseMonkeyy]

i only have a very small compressor so i wouldnt know but i would like to hook it up to a boiler

[suggweezy]

thats bull because if u look closely the fly wheel is going back and forth cause the piston cant cum back up cause the air is pushing it back down there for its going back and forth

[GreeseMonkeyy]

hey suggweezy, the flywheel is actually spinning in full circles, and you can try this project yourself if you want to find out, just make sure u have the hose between the compressor and the motor

[TreyRust]

thats because his camera does not have enough FPS... is you watch an airplane prop, it looks like it is spinning backwards, then forwards, then very slowly.... thats because your eyes don't update fast enough, same principle applies to this video.

[jullepoju]

So you didn't have to block intake? Is it just pushing air in? or is there some kind of timing?

[GreeseMonkeyy]

well thats what amazes me, there is no timing on it, just hook up a rubber tube straight to your compressor and hook thye other end up to the spark plug hole and turn on the air

[mythril4]

@jullepoju

It is becaue a 2 cycle engine is open air until the piston is close to the top, by that time there is enough cintrifical force to finish the rotation. Once the piston pases TDC then the compressed air acts just like combustion. As the piston goes down the first open port is the exaust so theair escapes there, any remaining air escapes when the final port is exposed. This is why you see the motor struggle everytime it reaches compression.

[jomes31]

the first one sound cooler

[hheywire]

hey check out my air engine, same deal but a smaller two stroke

[robinhooodvsyou]

Try to use a car gear type oil pump as a compressed air/steam engine. I did it with steam....

[pixuma]

i can't get mine to go 360... will it work if i just open the regulator or do i have to dump it in with the valve all at once

[GreeseMonkeyy]

do you have the rubber tube like on mine? because it will not work when u hook it up straight to the compressor

[pixuma]

i have it hooked up to the compressor hose but not that kind of hose, i guess it kind of acts like a place for the air on the compression stroke to go instead of trying to press up against a high pressure hose?

[cambigfoot88]

you have to get a solenoid valva and reed switch! watch greenpowersience channel and search air engine :)

[Joeyad4]

what is in the spark plug hole is it just an air fitting

[GreeseMonkeyy]

its just a 1/4 hollow screw thingy for pipeing

[guitarsncarz]

If you had an old 2 stroke, twin cylinder motorcycle engine, with the tube and everything, would it still run without any valves? Because if you could get one to work it would put out some serious torque.

[GreeseMonkeyy]

ya i wanted to try that, but i think it would work really well

[pixuma]

look for an old yamaha banshee motor

[ballsniff13]

hey i did that befor and make sure to put oil in it because you will score the hell out of the piston rings and it wont work man

[TJScott2012]

not trying to be a critic, but squirting oil in the engine will only blow out the exhaust like it was designed to do on the two stroke.

[nismoskyline123]

wow that sounds nice how much PSI does it take to make it run? I have only been using vacum motors

[GreeseMonkeyy]

it needs about 20 psi to idle without dying

[melvis24]

Runs great. I thought a two stroke engine would'nt run as good on air as a modified four stroke engine. Do you think it's powerfull enough to run a bicycle? I intend to "update" my bike. What would you redommend as an portable air-tank?

[GreeseMonkeyy]

i dont think it would have enough power to go on a bike, for that i think u would need a solenoid on the engine so ther is not as much resistance, but a scuba tank would probably be a good portable air source

[kwacz]

so how did you get it to run off air. are there any engine mods. is this only good for 2 stroke engines. What did you do for lubrication.

[GreeseMonkeyy]

all i had to do was hook up a one foot rubber tube to the spark plug hole and then attach an air compressor to the other end of the tube, i did not mod the engine in any way and this method does onlly work on 2 strokes, and to lubricate it i just put a few squirts of oil into the crankcase and cylinder

[kwacz]

if i put a solenoid valve on there so that it only adds air when in the intake stroke, would it run more powerful and efficient. also should i remove the carb and put a plate over the intake port.

[GreeseMonkeyy]

yes a solenoid would make it run better,butt u should leave the intake port open so u can put oil in it

[kwacz]

you could mix the oil and air then pass it to the engine. just like an air tool auto oiler works. all you prob need is a very light mist. the oil wont really disipate for a while because there is not enough heat to burn it.

[GreeseMonkeyy]

that would work but i would still have to lubricate the crank shaft

[srasco78]

Thats sweet... I never thought of running one that way, guess its similar to the Air Hogs plane air motors. Got me a another project now.

[GreeseMonkeyy]

ya its pretty cool how it runs like that but u should check out my other air engine because on that one u can see the crankshaft spinning so its pretty cool
