Motivation
The world needs an
alternative to fossil fuels…
Department of Mechanical Engineering, JSCOE 4
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.
Department of Mechanical Engineering, JSCOE 5
Problem Definition
To convert a conventional two stroke spark ignition
engine into a zero pollution compressed air operated
engine as a practical sustainable alternative energy
technology solution.

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.
Department of Mechanical Engineering, JSCOE 10
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.

Department of Mechanical Engineering, JSCOE 19
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.
