2. INTRODUCTION
 WHAT IS PNEUMATIC BIKE
 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.

3. 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.

4.  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.

7.  Analog signals are sent to relays thereby playing an
immigrant part in switchover of power from electric motor
to pneumatic cylinder.

8. PNEUMATIC CYL
INDER 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

10.  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.

11. 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.

12.  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.

13. DESIGN ANDPARAMETERS
 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.

14. 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.

15. SALIENT FEATURES
 Pollution free.
 Light on the pocket.
 Helps conserve gasoline.
 Dynamic braking.
 Reverse rotation capability.
 Exhaust air sent back to atmosphere.

16. DRAWBACKS
 Cannot handle high loads.
 Lower efficiency
 Low pickup

17. CONCLUSION
 The bicycle can be designed and modified according to
person’s aspects.
 The exhaust air from the vehicle can be reused and
passed to the compressor. So refueling of the air can be
minimized.
 High power motor and good suspension can be used in
pneumatic bikes

18. LiteratureReview
• 1-V. Lohit A. Imran Mohideen (October 2014) According to this research paper a pneumatic bike is represented in which IC power
engine is removed by the pressurized air power and obtains the reciprocating motion of the piston, this motion is obtained by the
continues reciprocating of the pneumatic cylinder and reciprocating motion converted into rotatory motion by the crank. It uses the
compressor for compressing the air, torque sensor, NC & NO relay (normally closed and open relay), and a pneumatic cylinder.
• 2-P Madhu Raghava, T. Lokesh, M. Ravichandra, O.Jayaramudu (April 2017) According to this research a tricycle which is moving by
the power of pressurized air, the pressurized air is used in the 1.3 hp ratchet fixed at the bottom of the body and when the
pressurized air reach on the ratchet, it rotates the sprocket and transfer the motion with the help of chain to the rear shaft wheel.
Basically, it develops a tri-cycle for handicapped people over the manually operated wheelchair in the development, it uses a 12V dc
compressor for compressing the air, electrical control unit for control the supply of electricity and fluid power actuators and hose pip
• 3- Valmik patel1*,Shalin shah2, pankil shah, jay patel4(2017) the technology of compressed air vehicles is not new. In fact, it has
been around for years. Compressed air technology allows engines/ motors that are both non-polluting and economical. We designed
3 wheeled vehicle in order to reduce weight. Unlike conventional transmission systems which include clutch, counter shaft, fly wheel,
propeller shaft, differential, the pneumatic motor has been connected and coupled to the rear wheel with the use of an intermediate
gear box reducing transmission losses and weight of the vehicle. It also occupies lesser space compared to a four wheeler. But in-
depth research is required to completely prove this technology for its commercial as well as technical viability
• 4- Chaman Meena1 , Tarun2 , Jitender Kumar3 , K.D Sharma4 –May(2018)pneumatically operated vehicles is very broad, many types
of research had been conducted in it, the reason why the researches were conducted in the development of eco-friendly vehicles.
The basic idea or principle on which their researches were done was providing compressed air to a pneumatic actuator and making it
to provide a reciprocating motion and father this reciprocating motion was conducted in rotator motion
• . 5- Rayon Robert, Sharath Machaiah A.M., Jose K. Roy, Santo Sunny, Chennakeshava R (2018) In this review paper, the power system
of the conventional C engine is replaced by the pneumatic system. It uses a compressed air to run the double acting pneumatic
cylinder. It uses the reciprocating motion of double acting cylinder to run the wheel of a bicycle with the help of a slider crank
mechanism. It uses the hall effect sensor to measure the frequency of the rotating wheel, the measured frequency of the wheel is
indicated in the display connected to the control unit. The sensors also help in controlling the frequency of opening and closing of the
pneumatic valve
