INTRODUCTION

Fuel is one of the key vital energy on which the world is focusing now

.Minimum consumption of the this energy helps in reducing the

degradation of natural resources

The aim of the project is to produce the rotation motion by using magnetic

equipments with the help of Neodymium-Iron-Boron(strongest magnet)

WHAT IS A MAGNETIC FIELD?

A magnet produces a vector field, the magnetic field, at all points in the space

around it. It can be defined by measuring the force the field exerts on a

moving charged particle, such as an electron. The force (F) is equal to the

charge (q) times the speed of the particle times the magnitude of the field (B),

or F = q*v x B, where the direction of F is at right angles to both v and B as a

result of the cross product. This defines the magnetic field's strength anddirection at any point.

WHAT ARE THE TYPES OF MAGNETS?

There are three main types of magnets:

Permanent magnets

Temporary magnets

Electromagnets

Permanent Magnets

Permanent magnets are those we are most familiar with, such as the magnets hanging ontoour refrigerator doors. They are permanent in the sense that once they are magnetized,

they retain a level of magnetism. As we will see, different types of permanent magnets

have different characteristics or properties concerning how easily they can bedemagnetized, how strong they can be, how their strength varies with temperature, and so

on.

Temporary Magnets

Temporary magnets are those which act like a permanent magnet when they are within a

strong magnetic field, but lose their magnetism when the magnetic field disappears.

Examples would be paperclips and nails and other soft iron items.

Electromagnets

An electromagnet is a tightly wound helical coil of wire, usually with an iron core, which

acts like a permanent magnet when current is flowing in the wire. The strength andpolarity of the magnetic field created by the electromagnet are adjustable by changing the

magnitude of the current flowing through the wire and by changing the direction of the

current flow.

Neodymium-Iron-Boron Magnets

NdFeB magnets are the strongest permanent magnets around today, and are not veryexpensive. They are used in headphones, disk drives, new toys, all over the place.

a. Mechanical ShockThese magnets are brittle - they will chip or crack or break easily when:

dropped onto a hard surface

allowed to smash together with another magnet

allowed to smash together with a piece of metalstruck with a hammer or other hard substance

So again, handle gently, like you do with your iPod or cell phone. When you bring twomagnets together, be prepared to have the force of attraction increase quickly and

dramatically as the North pole of one gets closer to the South pole of the other. Better still,place a plastic disk or rubber washer between them so there is a cushion between them.Watch your fingers so they don't get pinched! Because these magnets are so much stronger

than others, this needs to be a real precaution!

You may not realize it, but every particle within a magnet wants to push away from everyother particle next to it. Yes, it is attracted to the particle at its North end and South end,

but all along its sides, there is a repulsion. Because of this, if two magnets are allowed to

smash together, expect a small chip or particle to fly away at a high velocity and can flyinto your eye. That is why it's a good thing to wear goggles - protect your eyes from the

unexpected. Those particles have sharp edges and will easily scratch your eyes.

b. HeatThis is the weakness of this magnet.

Their maximum working temperature is only 150 degrees C (302 degrees F).

The Curie Temperature for NdFeB magnets is 310C (590F).

This is why they usually aren't used in motors. Keep your magnets cool.

c. MoistureThis is another area of weakness. To combat the problem of these magnets corroding so

easily, they are usually coated or plated. A popular plating material is zinc since it is

cheap, but it isn't very good. A better coating is nickel. This keeps them looking nice and

shiny for a long time. Some are coated with a very thin layer of gold over the nickel. Thisis more for looks, but is also useful since gold does not tarnish.

d. Demagnetizing FieldsThis is an area where these magnets outperform others. They are tough to demagnetize.

This also means that they can easily demagnetize other classes of magnets - like SmCo orAlnico or Ferrite! Again, store your magnets separately by class.

The power is obtained from the magnets

north poles repel north poles

south poles repel south poles

north poles attract south poles

south poles attract north poles

We are using repletion force of the magnets

Due to the force the piston moves front and back .

Connecting rod is connected to the eccentric shaft

The piston is connected to the connecting rodDue to the (piston movement) motion the rotation is obtained

Crank shaft :

The crankshaft, sometimes casually abbreviated tocrank, is the partof an engine which translates reciprocating linearpiston motion intorotation.

To convert the reciprocating motion into rotation, the crankshaft has"crank throws" or"crankpins", additional bearing surfaces whose

axis is offset from that of the crank, to which the "big ends" of theconnecting rods from each cylinder attach.

Here's a rough estimate based on general numbers. On average the personal vehicle is driven12,000 miles. The average efficiency is 21.5 miles per gallon. So the average gasoline used by

each vehicle is 580 gallons annually. According to the US Bureau of Transit Statistics there were250,844,644 registered passenger vehicles in 2006. The population of the USA is 300,000people. So automobiles times gallons per auto, divided by persons comes to 486 gallons of gasper person.
