Air Compressed Car

Well, there are several designs.

Compressed air. These vehicles have a rather limited range. Range is limited by the size of the compressed air tank, or the length of the on-board hose.

"How does a air compressed car work?"

Very badly. Very short range.

If you are referring to a pneumatic car crusher the car gets considerably more compact but the trade off will be that it no longer works for transportation duty nearly as well as it used too.

Plan A: Expand compressed air through an air motor (vane or various other types).
Plan B: Expand compressed air through a nozzle, like rocketry.

_{How does a air compressed car work?}

Which one do you mean? A car which is compressed by air ? Or a car which uses compressed air to run?

If the first one, then you compress the car and its occupants, all made of springy material, and allow them to expand in the proper direction to make it move....

If the second one, there are many such cars if you do google search, but for "Compressed air car"

Please see previous threads on CR4 on the subject as myself and others have spent a lot of time explaining the concept and the advantages and disadvantages of engines and designs over the years.

Short answer is badly in comparison to just about any other engine or form of powered transportation.
