Hydrostatic power transmission at the wheels?

Posted: 16 Jul 2011 07:05 PM PDT

Can the concept of a screw air compressor be reversed to transmit drive to the wheels?
Engine can be used to run a compressor, a highly compressible gas like nitrogen maybe used.....
Compressed gas to be stored into a tank.
Out put valve to feed compressed gas to "reversed air compressors" at wheels,drive can be adjusted by controlling this valve .
Engine starts at a minimum pressure at storage tank and stops at max pressure.

this is what i had in my mind,some benefits of this concept is maximum fuel efficiency due to constant rpm of engine,takes out the weight of gearbox,propeller shaft and differential unit.

Turbo Machines

I intend to carry out a research based project on Turbo Machines especially for CNG vehicles, I wanted to know the amount of the gas being dispersed in an IC engine, I intend to know the flow rate of the gas. Also if I am not wrong the gas gets dispersed at atmospheric pressure, so what type of pressure regulators are used which have the capacity of turning down the pressure ratio of whopping 200 :1 ?
