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.

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.
