PROJECT TITLE: COMPRESSED AIR VEHICLES

Presented by : Shreya Jitesh Jayanth A V Sachin Sathish Hemanth L Lavanya N

PROBLEM STATEMENT Fossil fuels like petrol and diesel pollute air abundantly in the metro city Delhi.

SOLUTION � Modify the current 4 stroke engine to run with compressed

air as the fuel. � Redesign the pressure to the inlet of the engine to increase

the speed and load carrying capacity. � Make a prototype which can travel for a maximum uniform

distance at one charge.

DESIGN OF STRUCTURE

WORKING �  Piston One – takes in air compresses at 300 psi and 200º F in

compression chamber during first cycle of the engine. �  Piston pauses and small amount of air is released in expansion

chamber and created a low pressure of 140 psi with low temperature and low volume.

�  A high speed shutter connects the compression and expansion chamber

�  Sudden pressure and temperature difference in the two chamber creates pressure and wave in expansion chamber produces work in that drives the piston to drive the engine.

COMPRESSED AIR TANK

o  The compressed air tank is made of carbon fibre which can hold 80 kg of air compressed to 300 bars.

o  In case of major accident, the tanks do not blow up like metals and the air just gushes out to the surroundings

o  The tanks are composed of an interior thermoplastic container which ensure it is airtight and is held in a coiled and crossed carbon fibre shell

COST ANALYSIS Cost Analysis can be broken down mainly into following and can only be approximately estimated. 1.  Engine - ₹ 4,000/- 2.  Chassis - ₹ 9,000/- 3.  Steering, Braking, Transmission and Drive System - ₹ 15,000/- 4.  Air Tank and the connections - ₹ 15,000/- 5.  Tyres - ₹ 2,000/- 6.  Rest of the Fabrication charges - ₹ 5,000/- Total: ₹ 50,000/-

OPPURTUNITIES THREATS

�  Huge demand in automobile industry for alternate fuel vehicles • Cheaper running costs • Increase in job market in this sector

�  Achieving 4500 psi of

pressure to compress air and store it requires special mechanism.

�  Nominal speed is only 60-80 km/hr.

�  Availability of charging stations is very less.

CONCLUSION �  Air Powered cars is a realization of latest technology in the

present automobile field. �  This concept is used in Germany and there about 75% of

automobiles are working on the same principle. �  If this concept is utilized in our country, then there will a lot of

improvements in Automobile field. REFERENCES �  Global Journal of Research in Engineering Automotive �  Matt’s Sullivan World’s First Air Powered Car (
