Pneumatic Engine

Now is the time to look for the new technology to make us independent from the fossil fuel old technologies, I thought of lots of new inventions but some flaws are there, then I thought about the Pneumatic Engines. We can store highly compressed air, and can use that air in a Wankel Engine to move the rotary piston, as shown in the figure below:

Intake (Through Intake Port 1)

The compressed air is drawn in the intake port during this phase of the rotation.

Expansion (instead of Compression)

The compressed air will move the rotary piston and it will Expand, Hence give the power to the Engine.

Intake (Through Intake Port 2)

Again the Compressed Air is allowed through the Intake Port 2 to the Engine, as shown.

Exhaust

And finally the expanded air is expelled here in this stroke.

The rotary motion is transferred to the drive shaft by an eccentric wheel (illustrated in blue) that rides in a matching bearing in the rotor.

We are using Wankel Engine here, as it is more efficient than Piston Cylinder Arrangement also cheaper than the Turbine Technology.

Not only this, the Expelled gas has some Energy so we can also convert its remaining Energy for other purposes.

No doubt it has some complications but we can remove those, also the complications are comparatively less challenging than any other technology which are under research, with very less modifications we can make Engines, which are comparatively highly efficient, directly it is not emitting any amount of Pollution if we count then indirectly it will consume some energy to compress the Gas, but that can also be done with the help of Electric Energy. So we can achieve a possibility which is 100% pollution free.
