INTRODUCTION

The vehicle uses fluid system instead of the Internal

Combustion engine.

Will help save the non-renewable sources of energy.

Will aid in reducing the problem of global warmingsince two wheelers contribute to the problem the most.

Working Methodology

Reciprocating piston of pneumatic cylinder

drives the crank shaft.

Power system consists of electric motor and

pneumatic cylinder.

Electric system helps in overcoming the initial

torque to drive the vehicle with load.


3/17

Electric motor is active until about 20 km/hr.

Switchover of power to pneumatic cylinder

takes place by relay operations.

Torque sensor is the transducer.

Torque sensor converts the torque acting on thewheel into analog signal.


4/17

Analog signals are sent to relays thereby playing

an immigrant part in switchover of power from

electric motor to pneumatic cylinder.


5/17

Pneumatic Cylinder

Piston of pneumatic cylinder made to

reciprocate continuously by means of sensors.

Sensors (reed switches ) are placed at either end

of pneumatic cylinder.

Solenoids and solenoid valve control movement

of piston of pneumatic cylinder.

8/17

Signals are fed to the solenoid valve by sensors.

The piston reciprocates based upon the side

from the signal is fed from the cylinder to the

solenoid valve.

The reed switches are of high precision and

accuracy thereby giving approximately 450

strokes/min.


9/17

Speed And Braking

Speed is regulated by means of metering valve.

It meters the flow of air inside the cylinder.

Valve can be used to regulate the flow.

That is increase as well as decrease.


10/17

Braking is used to stop the vehicle at

instantaneous hindrances.

Is achieved by the metering valve which

completely stops the air flow.


11/17

Optimal design is achieved by

considering the various design

parameters.


12/17

Design Parameters

The various design parameters are:1. Piston Diameter : The piston dia = 25mm

2. Flow Rate From Compressor :

The flow rate required

from the compressor is

0.25 L/s.


13/17

3. Power : The power delivered after initial

torque is overcome is about 0.89 HP-

1 HP.

4. Torque : It is the essential parameter

T= 3.15 N-m is produced after initialtorque is overcome.

5. Speed : The wheel rpm is made proportional

to engine rpm. The max speed is about 51 km/hr.


14/17

Salient Features

1. Pollution free.

2. Light on the pocket.

3. Helps conserve gasoline.4. Dynamic braking.

5. Reverse rotation capability.

6. Exhaust air sent back to atmosphere.

Conclusion

Even though the vehicle is in its early stages ofdevelopment, It holds a lot of promise andprovides scope for further research.

Now the responsibility is entrusted upon us asengineers of tomorrow to develop the concept

and make it feasible so that it reaches thecommon man and we get a better environmentto live in.
