Student name:-1) Sk samsuddin2) Vivek Wankhade

Under The Admirable Guidance Of:-Prof.U.N.Galat

Why Introducing This Project ???

India’s population 127,42,39769 and growing.Apr 8, 2014 - India has an youth demographic

65% of its population.Census 2001 has revealed that over 21 million

people in India as suffering from one or the other kind of disability mainly injured from leg. This is equivalent to 2.1% of the population.

April 1, 2011 it increased to 3%.Dec 29, 2013 - The country's disabled

population has increased by 12.4% , most of the causes for accident.

Now World population :-According to the United Nations, world population reached 7 Billion on October 31, 2011. The US Census Bureau made a lower estimate, for which the 7 billion mark was only reached on March 12, 2012. Some Facts about Persons with Disabilities. ... Around 15 per cent of the world's population, or estimated 1 billion people, live with disabilities. ... Often employers assume that persons with disabilities are unable to work due to lack of their leg condition.

INTRODUCTIONCompressed air as a source of energy in different uses in

general and as a non-polluting fuel in compressed air vehicles has attracted scientists and engineers for century.

The latest trend in the automotive industry is to develop light weight vehicles. Every automotive industry is looking to reduce the weight of the vehicle as it helps in the better handling of the vehicle and increases the efficiency of the vehicle.

Today, the heavy vehicles are known for producing a large amount of harmful gases like CO2, SO2 etc. which act as the major source for global warming.

So research is going on to find a light weight vehicle which does not pollute the environment. One of the alternatives is the use of compressed air to generate power to run an automobile

HISTORY In fact, two centuries before that 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.

Numerous locomotives were manufactured and a number of regular lines were opened up (the first in in 1879).

In 1892, Robert Hardie introduced a new method of heating that at the same time served to increase the range of the engine which in turn helped to increase the distance that could be traveled at a stretch.

However, the first urban transport locomotive was not introduced until 1898, by Hoadley and Knight, and was based on the principle that the longer the air is kept in the engine the more heat it absorbs and the greater its range

LITERATURE VIEWLatest Developments of a Compressed Air Vehicle

Compared to batteries, compressed air is favorable because of a high energy density, low toxicity, fast filling at low cost and long service life. These issues make it technically challenging to design air engines for all kind of compressed air driven vehicles.

Concept and working This project is working on the basis of compressed air and

double acting cylinder. The compressed air stored in the tank . And the double acting cylinder which is attached to the crank of the vehicle which give the motion to the vehicle.

The compressed air supply to the double acting cylinder through the pipe line arrangement and with the help of the flow control valve. The flow control valve operated by the switch .

The double acting cylinder’s one end attached to the frame by pin joint and other end attached to the handle or crank which gives reciprocating motion to the crank and the crank rotated which provided circulating motion to the wheel and the wheel rotated. And in this way the vehicle gets motion.

ADVANTAGESIn comparison to petrol or diesel powered

vehicles “air powered vehicles” have following advantages:

Air, on its own, is non-flammable, economical, transportable, storable and, most importantly non-polluting.

The mechanical design of the engine is simple .

Low manufacture and maintenance costs as well as easy maintenance.

APPLICATIONIt is very helpful for handicap peoples to run

their vehicle.It is free from pollution. it cost is low than other vehicles costThe vehicle weight is light and easy to

maintenance.No conventional fuel is used in this vehicle.

CONCLUSION It’s important to remember that while vehicles running on

only compressed air might seem like a distant dream, but they still have public interest due to their environmental friendly nature. Compressed air for vehicle propulsion is already being explored and now air powered vehicles are being developed as a more fuel-efficient means of transportation.

Pneumatic vehicle will replace the battery operated vehicles used in industries. Pneumatic powered vehicle requires very less time for refueling as compared to battery operated vehicle.
