OBJECTIVES To replace the conventional two wheeler

.power source by fluid power source

To meet environment pollution and.regulation act To save the economy of the nation and as

.well as every individual

.To bring zero pollution factor

CONSTRUCTIONBasic set up consist of four parts

COMPRESSOR The compressor has a motor whose supply is.fed from a rechargeable battery The air compressor increases the pressure

of gas by reducing the volume of gas as

.described by the perfect gas laws

LECTRIC MOTOR : Electric motor is a rotary actuatorwhich is used initially to drive the

vehicle to overcome the initial torque.required to drive the vehicle with load

Once the vehicle gains the initialmomentum and the running torque and a( / ),stipulated speed say 20 km hr the power

system is switched over to the pneumatic

.system from the electrical


8/23

This is achieved by simple relay

.operation & (NC NO RELAY NORMALLY CLOSED AND OPENED) -RELAY The NC 1 relays which feeds thesignal from the torque sensor whose signal

-is of the analog form and therefore NC 1- . .becomes NO 1 i e no longer motor is used.to drive the system

,Similarly signal from the other end from

-the same sensor is fed to NO 2 there by- - .making NO 2 as NC 2 Therefore the relay operation acts as a

.bridge for switching the power system


9/23

TORQUE SENSOR:- Torque sensor is a transducer which

converts the torque acting on the wheel

.into analog signal The signal is thensend to the relays and thereby playing animmigrant part in switching over the power

.from motor to cylinder

The cylinders which now start.reciprocating become the drive source


10/23

The sensor picks up the pressure causedby the cylinder during extension and.retraction The signal from the sensor is

fed to solenoid valve which subsequently

shifts the ports based on the side the.signal is fed to the valve


11/23

NEUMATIC CYLINDER :- Pneumatic cylinder is made to

reciprocating continuously by means of reed

( ).switches sensor The reed switches are of high precisionand resolution thereby giving approximately

/ .450 strokes min

The pneumatic cylinder is prime actuatoronce the power system transfers to.pneumatic system

ORKING METHODOLOGY The principle of generation of power ina two wheeler is by means of fluid power

and there by replacing the power system of.conventional engine This is achieved by the continuous

reciprocation of pneumatic cylinder where

its rod ends are linked to the crank of an.engine


14/23

The linear reciprocation of cylinder is

.converted into a rotary motion The vehicle runs on the power produced

.by the air

The fluid hitch is the main source of.supply is sent in the pressurized formThe fluid is compressed in the rated

pressure to the rated pressure for the

.desired power

SPEED AND BRAKING

Speed is regulated by means of meteringvalve which meters the flow of the air.inside the cylinder

The valve can be used to regulate the

.flow to increase and as well as decrease The regulation would give the speed.variation or the vehicle

Braking is achieved to stop the vehicle

at the instantaneous hindrances.


17/23

This is achieved by metering the valve.which completely stops the air flow Note once the torque increase the motor

,is employed so in order to stop this the

hand brake is applied which act as switch,between the supply and the motor.eventually cutting of the supply


18/23

:-MECHANISM

The design mechanism is the key part in.achieving it The arrangement is in such a way that

linear motion of the pneumatic cylinder is

converted into rotary motion by connectingthe rod end of the cylinder to the crank.of engine

The entire head of the engine is

dismantled and only the crank rod is taken.along with the chain sprocate


19/23

Power stroke obtained is directly

proportional to the pressure at which the.air is sent

This is an effort to substitute and

optimize the conventional design of the

vehicle to simple and lighter construction.


20/23

ADVANTAGES:-

As air is used as a fuel it produces zero.pollution these bikes are ecofriendly

,Silent in operation thus reduces noise

.pollution .These bikes are light in weight It reduces the consumption of natural

,fuels like petrol diesel etc.


21/23

:-ISADVANTAGES ( - / ).Less speed up to 60 70 km h .Frequent maintenance is required It has a high cost.


22/23

CONCLUSION:-

We hope this paper gives a vision of whatextent we engineers can value to this.nation

. .Thus if we replace conventional I C powersystem by fluid power system then it is

.always beneficial to us
