New Idea: Air Compressor Engines

[rosh009]

recently i read an article on engines that work on compressed air.ie.they use only air as fuel.
these engines have so many advantages that some years from now,sureshot they are going to rule automotive industry.
but as of now there are many difficulties to be tackled with.
and one usual difficulty faced by all innovations is bringing the working model in the lab to common man usage
so,what i ask s is to list some of the ways through which we can bring about a change in the approach to tackle this issue!
let me start it myself:
my idea to tackle this issue is instead of introducing the newer version into the market try to modify the existing one in such way that it works under the new concept.
for example,it would be great if we can modify the existing IC engine into the air-compressor one.in which case:*people need not discard their existing vehicle to shift to the new technology*immediate shift from old technology to newer one[infact u may call it a revolution]*most importantly great reduction in pollution inturn contributing to reduction in global warming!!!

Boy o Boy! That's something similar to what I wanted to see on CE. I'm sure we are off to a great start . I request all CEans to take this up and get started. We may contact colleges/labs/companies to actually get this 'Done'.

Mechanical Engineers! Get Started!

Thats an excellent idea, but how do 'you' propose we make this possible?!

1. What research have you done on this topic?

2. What changes do you propose to the existing engines so that it can accept compressed air as fuel?

3. What will be the cost requirement to implement this idea.

4. will it be safe to just incorporate it to the existing design?

These are a few questions I have asked so it is easier for us CE'ns to carry on with the creative reasoning and coming up with good solutions.

Cmon guys, this is a good topic, look into it a bit more!

1.well!as such i havenot done any research on it.
2.i'm still finding out the changes in the existing one.once i feel i've covered all the requirements i'll post it.
3/4.and regarding cost requirementand safety,i feel first up we need to explore all posible ways to implement this idea no matter what the costs are.
once,we finish exploring those possibilities,then we can choose the most economical and the more safer one among them.

and yes xheavenlyx,this is an important topic because with global warming escalating and the atomic clock ringing danger music,its high time that we stand up and contribute in someway or the other to "STOP THIS TORMENTOR CALLED GLOBAL WARMING BEFORE IT STOPS US!"

[xheavenlyx]

"STOP THIS TORMENTOR CALLED GLOBAL WARMING BEFORE IT STOPS US!"

umm, is that US or U.S. ? (no pun intended, seriously)

1.well!as such i haven't done any research on it.
2.i'm still finding out the changes in the existing one.once i feel i've covered all the requirements i'll post it.

Well, for one thing, research is very important, and by that i mean study the present design characteristics that is specific to the pistons, valves etc.

Some points that i could think of is:

-valve sizes are important, and their pressure handling capacities. You could use steam as you suggested. However, know that its very possible that this type could be immensely inefficient as compared to a deisel and petrol one. Thats the reason we use Gasoline.

I am not being pessimistic, just critical. Its good since you can work harder to disprove this theory.

Another thing I'd suggest you to look into is the idea of Efficient Electrical systems, which can be a combo of Solar, Battery (Li-ion, CdNi etc), Fuel-cell etc. Which are way more efficient.

But as you had already pointed out, you want a system which customizes and improves the present system. So the above suggestion can be avoided at your discretion

Keep on reading, writing and thinking. Good luck!

Good going friends. Mechanical engineers should participate. I have asked one of my friends to look into this. Hes been working with engines since last 2 decades.

OK OK OK....

PURE STUFF.. IS'NT IT GUYZ....

LET ME EXPLAIN YOU THE MATTER IT IS CONSIDERED WITH... ACTUALLY THIS IS AN INITIATIVE FROM A GERMAN WHO STUDIED STEAM ENGINES A LOT. AFTER THAT AS A TYPICAL STEAM ENGINE LAYOUT HE HAD A DESIGN FOR A COMPRESSED AIR ENGINE. IE. IT HAS ONE OPENING FOR COMPRESSED AIR WITH TWO CHAMBERS. THE AIR ENTERS THE FIRST CHAMBER AND MOVERS THE FLUCTRUM TOWARDS THE OTHER AND DUE TO THAT THE FIRST ONE IS CLOSED AND THE 2ND ONE OPENS AND IT ALSO DO THE SAME AND GET ITSELF CLOSED AND MOVES THE FLUCTRUM TO 1ST .. THIS RESULTS IN A TYPICAL RECIPROCATING MOTION AND RESULTS TO A 0.5 STROKE ENGINE WITH A PERFECT POWER OUTPUT.

( I WILL PROVIDE YOU THE DRAWING SOON)

BUT SINCE THIS IS MECHANICAL.... PROBLEMS DO RAISE (joking)

IT CAN PRODUCE AN EVEN BUT LEES TORQUE BUT VEY POOR IN BRAKE POWER. IT PRACTICALLY CARRIED 5 HEN OF .75 KG EACH. THIS IS THE RESULT. OTHERWISE BEFORE THE INVENTION OF COMBUSTION IGNITION ENGINES ONLY, PEOPLE HAD MANY DREAMS ON THIS CONCEPT. ANY WAY GUYS... HAVE YOUR BRAINS MUCH MORE SHARPER... ANY MORE DOUBTS ..LEAVE U R REPLIES HERE...

pls elaborate this topic by giving some external website links

I think it is a great idea of bringing the revolution in automobile industry bu using the air compressor on behalf i.c. engines.

According to my idea we can do something like this: -

first of all the engine get started by the same method as of i.c. engines & after picking up the speed we can use the air that is striking to the vehicle as the fuel for compressor (because the coming air has got a very high kinetic energy). the high K.E. air will strike the blades of the compressor and ultimately supply the extra torque to the vehicles.

This method can greatly reduce the load on the small engine's and can tackle the more load then the existing one.

A friend of mine thought of this years ago and though he had THE SOLUTION... I had to explain to him that it takes energy to compress the air, and when you consider the loss via friction, there is an energy deficit, meaning a compressed air engine will ultimately cost more. If compressed gas was the easily captured waste by-product of a lot of industrial processes, it might be a different story... Then consider storage; it is the current debate regarding hydrogen vehicles, how to store it in as small a space as possible; with compressed gas, the range (if the compressed gas were to be where the gas tank was) is only a few miles.
