How Many of You People are Aware of Air-Run Engines

yup its good...but do send the design for a ref. dude🎉

No, I will not send anyone a design or complete a project for you, dude. I think that was clearly stated.

I hope people will like to discuss this concept, propose specific questions/answers or debate practicality/future use of such a design. If so, please post! Otherwise if we only have beggars I am done with this thread...

boss me tooo ready

Here i am posting my project videos...

Thanks for sharing the vids!

seen about it on discovery long ago😁

hi friends.....


Yes, it could. You could compress the air at your house using an air compressor, fill a compressed-air tank in the car, and the car could run off of it. You could use an engine very similar to a #-Link-Snipped-# (using pressurized air instead of pressurized steam) to convert the compressed air to rotational energy
The main problem you would have is the size of the "gas tank" you would need to get any kind of reasonable range. You would need a LOT of compressed air to take a car very far.
An alternative would be to use a liquefied gas like liquid nitrogen. You can think of liquid nitrogen as air that has been compressed so much it has liquefied. Liquid nitrogen is much denser than compressed air, so you could store enough in a car to give it reasonable range. You could then fill up at the liquid-nitrogen station.
A compressed air car would generate no #-Link-Snipped-# while you are driving. However, the #-Link-Snipped-# that produces the electricity that compresses the air (or liquifies the nitrogen, for that matter) is probably generating pollution from the coal or oil it is burning. Power plants are relatively clean and very efficient compared to #-Link-Snipped-#, so this is not a bad trade-off. Still, it's important to compare apples to apples.
Another thing that would be interesting to figure out is the efficiency of a liquid-nitrogen engine. If you burn #-Link-Snipped-# in a car engine, only about 20 percent of it powers the wheels. The rest creates wasted heat. It would be interesting to see how efficient a power plant is, plus how efficient a nitrogen liquefier is, plus how efficient a liquid-nitrogen engine is -- that would tell you whether you were creating a technology that is better or worse than the gasoline engine in terms of efficiency.

I appericiate the idea, but liquified nitrogen 😀shock😀 is not a really good alternative!!

First off, since it is stored under tremendous pressure, think of the increase in factor of safety and hence the cost!!!

Also there are following points to consider (Hope you don't mind me quoting from wikipedia):

"Frost formation

Unlike internal combustion engines, using a cryogenic fuel requires heat exchangers to warm and cool the working fluid. In a humid environment, frost formation will prevent heat flow. To prevent frost build up, multiple working fluids can be used. This adds topping cycles to ensure the heat exchanger does not fall below freezing. Additional heat exchangers, weight, complexity, efficiency loss, and expense, would be required to enable frost free operation.<a href="https://en.wikipedia.org/wiki/Liquid_nitrogen_economy#cite_note-Knowlen-1" target="_blank" rel="nofollow noopener noreferrer">Liquid nitrogen engine - Wikipedia</a>


Safety

However efficient the insulation on the nitrogen fuel tank, there will inevitably be losses by evaporation to the atmosphere. If a vehicle is stored in a poorly ventilated space, there is some risk that leaking nitrogen depletes the level of oxygen in the air and causes suffocation. Since nitrogen is a colorless and odourless gas that already makes up 78 % of air, such a change is difficult to detect."

Great to hear about the Air-run engines,
I was not aware of this type of engine until i saw this thread.

hi buddy!!!
yep we can run an engine with air
but condition is highly compressed air has to be used.
Also we cannot run these at high speeds..
if any extra information is needed pls ask me😀

It's good to get engines run in air mate...

Hi friend,
This is possible but it is not simple air but it is compressed air we are going to use here.
You can go to how stuff work for more information on CAT engine and car run compressed air .
Can You tell me, some project that i can do, in my winter vacation , i am 2nd yr mech. student.

is this technology, had advantage over oil, as this needs electricity .
is this not transferring from car to power plant ?
How much chances is their , to produce less pollution than fossil fuel used car ?

Guyz.. I'm back...
For those who are stil interested to construct the working model for their college project or so...
I simply request you go through the whole thread and raise your questions...
I wanna see how many are really interested to do this thing in material... than simply commenting on the thread with the then and their jargon which hit u r mind while reading someone's question 😛

#-Link-Snipped-#: I have been thinking about vehicles running on compressed air for some time. I was thinking about rotary air engines,I tried to do some calculations and develop a design, but never came up with something useful.Now after going through this post i realized that , i was trying to run even before I could stand.Am going to start with a clean slate now,will try to gain as much knowledge as possible and then try again.

Hi friend, I don't know about it.Please explain it.

@white-hat .. fine.. how about converting of air pressure in to force... That's the key for this design.

#-Link-Snipped-#.. Study the whole thread and then raise questions 😀
