The document describes a project to convert a conventional two-stroke spark ignition engine to run on compressed air. The project aims to develop a zero-pollution compressed air powered engine (CAPE) as an alternative energy solution. A literature review found previous research and commercial examples of CAPE technology. The design features of the project include modifications to the cylinder head, an electronic control system, and pneumatic circuit to control compressed air flow. Testing showed the CAPE produces power while eliminating pollution, with benefits of using only air, lower maintenance needs, and no fossil fuels. Future work may include multi-cylinder versions with improved air recirculation and higher torque.

5. What’s CAPE..?
A power producing device consuming
compressed air.
Compressed air is expanded inside an engine
cylinder to produce torque.
It produces no pollution.
It consumes no fuel; only the compressed air.

10. Project Concept
Sensor Pair Sends a
Signal to control
circuit
Due to disk
interrupting the light
path between
sensor pair, valve
gets open.
Air comes in and
pushes piston
downwards.

11. Project Concept
Signal from control
circuit latches the
DCV in position II.
Low pressure Air is
scavenged out the
cylinder through
DCV.
The flywheel starts
moving piston
upwards.

20. Conclusions
• Its possible to use Compressed Air to drive a Existing ICE’s by incorporating
a few simple modifications.
• Such a CAPE is capable of producing considerable power at substantially
low cost.
• Efficiency if CAPE is comparatively poor and a subject wherein more
efforts are expected.
• A CAPE produces absolutely no pollution.
• With successful completion of project the results confirm the
sustainability and effectiveness of CAPE as most promising technology to
eradicate the use of fossils and odds associated.
