Because it doesn't rely on heat. All engines convert heat energy into mechanical energy, this is simply being ran on air pressure alone which would be described as a motor.
no, engines are categorized as a device that converts chemical energy into working energy. Take for example a diesel engine. it converts the chemical energy stored in the diesel fuel, and turns it into energy that does work. This is considered an engine because air, even though inert, is something that has stored energy, and this device is harnessing that stored energy and putting it to work.
No my friend. The definition of an engine is a machine that converts thermal energy (heat) into mechanical motion or work. Air motors do not operate using thermal energy it strictly relies on pressure alone. Engines can only operate using multiple cycles (compression, ignition, combustion), or can operate on differential pressures caused by temperature changes (Sterling Engine). The device in this video does not rely on thermal energy.
WOW! Actually I have a few of these thing you can plug into an air hose and turn fasteners! New invention called the 'air wrench'. Also I have tools that shoot nails, powered by compressed air as well. Wow, the future time we live in is so wonderfully technologically advanced. Just imagine the concept of compressed air powering utility machines. Incredible! What will they come up with next I wonder...Astronomically voyaging robots? Oh wait we already do that
man, these take so much work to make. Sorry we don't all take the easy road and use an air wrench. Some of us like the challenge and the technology behind the steam/air engines.
So maybe we can congratulate them for showing us this fine piece of engineering and not just flame them from our comfy office chairs.
its a single piston air pressure engin, mutch like the steam enging but i would not be prepared to wright it off at this point after all i dont beleive oil regenerates its mass so it might be all we have one day.. wouldnt that be scary
The air motor goes back a long way, the 1864 whitehead torpedo was powered by an air motor using compressed air from a flask. Its range was hundreds of yards and speed about 12 knots iirc.
if they used a high pressure liquid eg. refrigerant..a single 25kilo bottle would carry on boiling off thus sustaining a high pressure for a very long time..u could go hundreds of miles with just 1 tank :D

this is not a motor. its a toy spun by compressed air. a motor has to generate its own power so if ithis is a motor. then its compressing the air used to run it and it is not.
the title is actually air engine, not air motor. a engine converts energy into mechanical force or power. in this case the momentum of the incoming air, a force, multiplied by a distance = N*m=Joules (energy) is converted to mechanical power when the shaft turns and lifts a weight a certian height in a measured amount of time (mass*grav*distance)/time=(Power) (kg*m/s^2*m)/s=Watts
A motor does not generate its own power. It cant or else that would be perpetual motion which is impossible due to friction. An electric motor converts electrical energy into mechanical. This air motor or air engine converts potential energy of compressed air into kinetic energy of a spinning shaft
@valduare dude, you are a tard, when you run a electric motor does it make electricity. (I know some double as a generator, but this could double as a compressor.)
did you make this motor if you did how do you get the air in to the haed i aks you that because i tryed to make a motor like tha but i guse that you beat me to it i tryed to use a rotor valve
Where the hell can I get one? I joined a yahoo group that is working on an open-source air powered car. We're looking at EngineAir's engine right now, but I could use a small engine for other projects.
why is it that the only thing some people focus on is the insignificant fact that they are wearing jewelry.... so what! They fact is they did something not many people here can do and thats what you clicked on the video to see
Great engine - shame about all the shitty comments. Some people build engines, and some people snipe from the sidelines I suppose. Some people create and others are pathetic.
Why not just clamp down this device or bolt it down so you don't need a team to hold it down to keep it from bouncing around? Seems like a more practical and safer way of operating it. You could wear all the bling you want too without worry of losing fingers.
we had just assembled it and wanted to see if it would run. some of the most basic tools are the hardest to find. hammers clamps and screw drivers are scarce and no one had the time to go on a building wide search for the elusive clamp lol.
not possible.... also air has condensation in it.. the tanks required to run the vehicle/motor would need a dryer before going to the engine. I suppose you could recycle a portion of the exhaust into a lower pressure tank & reduce the effort needed to compress further, but a self sustaining motor is a fools errand.
i dont quite think your right. i built a v12 20hp engine and then mounted it on a 1/3 scale duece and a half gun truck. on the back axle i put a recompressor piston on both sides of the axels going to both wheels so however fast you turn the axel the more compression you put into the tank. it also sustains 160psi
mostly yea we used whatever we found around the shop. the flywheel was copper. the crank was steel and brass and the cylinder with the cam was brass. the rest was aluminum.
no, you are right. that is the machine shop rule. no jewelry. also no open shoes, no loose clothing, long hair must be tied up. i was the one taking the video. what my team wanted to do with their hands is their business. i was just trying to defend them when that first guy said something completely uncalled for. this isnt a safety video on how to properly hold an air engine as it runs, its a video of a air engine that was designed and built by a few engineering students.
again with your shit talking. when you have not slept for two days your mind functions like a drunk bastard. i guess you have never had a deadline to meet.
halter63, with all due respect, it appears you're last three brain cells have finally broken off diplomatic relationships. Someone commented on the foolishness of wearing rings and bracelets on when working with moving machinery. You reply that "your teams has balls" and you were working under deadline pressure. How about just admitting that, "yeah that was dumb, I'll be more careful next time"? What's worse: a bad grade or an severed finger?
its fine if he wanted to mention it was foolish for my team to do what they did. if he said something to the effect of what you said in your comment like a warning KIDS: do not wear...around moving parts. i can respect that but he said it with sarcasm so i gave him a bullshit reply.
actually it didn't heat up and...seize i think was the word you were looking for. we were decreasing the amount of air pressure to see the minimum required to run the engine.
i have a sugestion 4 noise reduction without power lose, blow the exost through a read type device or over an orface like blowing acrose the top of a bear bottle will produce sound if u could produce a sound outsjde of the human hearing range .
Thats not bad. See now if we could get it to power a generator to create power to run the air compressor and the batteries for the electric drive system for a car i would say all u would need is ... Nothing but an oil change maybe on the air engine. Pretty good guys. :)
