SEMINAR ON PNEUMATIC VEHICAL PRESENTED BY RAHUL K. SHINGANE GUIDED BY Prof. IMRAN QURESHI

What is Pneumatic vehicle ? : 

What is Pneumatic vehicle ?

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. INTRODUCTION

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. Working Methodology

Slide 5: 

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.

Slide 6: 

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

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. Pneumatic Cylinder

Slide 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.

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. Speed And Braking

Slide 12: 

Braking is used to stop the vehicle at instantaneous hindrances. Is achieved by the metering valve which completely stops the air flow.

Slide 13: 

Optimal design is achieved by considering the various design parameters.

Design Parameters : 

The various design parameters are: Piston Diameter : The piston dia = 25mm Flow Rate From Compressor : The flow rate required from the compressor is 0.25 L/s. Design Parameters

Slide 15: 

Power : The power delivered after initial torque is overcome is about 0.89 HP-1 HP. Torque : It is the essential parameter T= 3.15 N-m is produced after initial torque is overcome. Speed : The wheel rpm is made proportional to engine rpm. 6. The max speed is about 51 km/hr.

Salient Features : 

Pollution free. Light on the pocket. Helps conserve gasoline. Dynamic braking. Reverse rotation capability. Exhaust air sent back to atmosphere. Salient Features

Drawbacks : 

Can’t take large load. Drawbacks

Conclusion : 

Even though the vehicle is in its early stages of development, It holds a lot of promise and provides scope for further research. Now the responsibility is entrusted upon us as engineers of tomorrow to develop the concept and make it feasible so that it reaches the common man and we get a better environment to live in.
