Nowadays, automobiles consume a large number of

fossil fuels. However, the consumption of fossil fuels

has brought many serious environmental problems,

such as global warming, ozone layer depletion and

fine particulate matter. To avoid such environmental

problems, renewable energy has been applied to

automobiles. A compressed air engine of a renewable

energy vehicle is introduced.

An engine is a device which transform one form of

energy into another form.

Heat engines, including internal combustion engines

and external combustion engines (such as steam

engines) burn a fuel to create heat, which then creates

motion.

Compressed air has been used since the 19th century

to locomotives and trains.

Dennis Papin apparently came up with the idea of

using compressed air (Royal Society London, 1687).

In 1872 the Mekarski air engine was used for street

transit, consisting of a single stage engine.

A compressed air engine is a type of motor which

does mechanical work by expanding compressed air.

A compressed air engine generally convert the compressed air

energy to mechanical work through either linear or rotary

motion.

Linear motion can come from either a diaphragm or piston

actuator, while rotary motion is supplied by either a vane type

air motor or piston air motor.

compressed air enters the cylinder via the intake valve because

of the pressure difference, drives the piston downward. Then

the intake valve closes when the crank reaches a certain angle.

While the compressed air continues to push the piston down

and output mechanical work. When the movement of piston is

close to the bottom dead center (BDC) the exhaust valve

opens, so that the compressed air with residual pressure is

expelled by the impetus of the piston. After the piston moves

back to the top center (TDC), the CAE completes a work

cycle.

Tata Motors has signed an agreement with Motor

Development International of France to develop a car

that runs on compressed air, thus making it very

economical to run and almost totally pollution free.

Although there is no official word on when the car

will be commercially manufactured for India.

It uses no gasoline or other bio-carbon based fuel.

Compressed air engines reduce the cost of vehicleproduction, because there is no need to build a coolingsystem, spark plugs.

Reduction or elimination of hazardous chemicals such asgasoline.

The engine runs on cold or warm air, so can be made oflower strength light weight material.

Refueling takes 3-4 hours

Limited capacity of storage tanks.

Limited speed range (110-140 Km).

When air expands in the engine it cools dramatically

and must be heated to ambient temperature.

Since this engine is not yet common it cannot be

refilled at home but needs a compressor.

Nowadays the need for energy continuously

increases, and we are using the conventional

resources at an alarming rate hence an alternative fuel

is much required and Compressed Air Technology

can be one of the best alternative, as the pollution

caused is zero and it is also cost efficient.
