Motivation
The world needs an alternative to fossil fuels…
Department of Mechanical Engineering, JSCOE 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.
Department of Mechanical Engineering, JSCOE 6
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 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.

Control System
Provides the information regarding position of piston and crank to control circuit.
Angle on the current valve timing disc is 132⁰.

Benefits of CAPE
Air Engine
Uses Only Air
No Need of Fossil Fuels
Needs Less Maintenance
Low in Cost
High Power to Weight Ratio
Zero Pollution

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.
