Transcript of Pneumatic bike
INTRODUCTION
The vehicle uses fluid system instead of the
Internal Combustion engine.
Will help save the non-renewable sources
of energy.
Will help in reducing the problem of global
warming since 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.
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 the wheel
into analog signal.
Analog signals are sent to relays thereby playing an
immigrant part in switchover of power from electric motor
to pneumatic cylinder.
PNEUMATIC CYLINDER WORKING:
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.

INDEX OF PNEUMATIC SYSTEM
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.
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.
Braking is used to stop the vehicle at instantaneous
hindrances.
Is achieved by the metering valve which completely stops
the air flow.
Optimal design is achieved by considering the various
design parameters.
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.
3. Power : The power delivered after initial torque is
overcome is about 0.89HP-1 HP.
4. Torque : It is the essential parameter T= 3.15 N-m is
produced after initial torque is overcome.
5. Speed : The wheel rpm is made proportional to
engine rpm.
6. The max speed is about 51 km/hr.
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 of development, It holds a lot of promise and provides scope for further research.
