Today there is need of alternate fuel for day today life. Fuel prices are increasing rapidly and environment get polluted from the emission of hazardous gases from fuel sources. Shortage of the fuel is expected from consumption. Hence there is need to reduce the emission of gases like CO, SO2, NOx, which are hazardous to nature. With reduced fossil fuel resources and increase in energy costs and environmental concerns, engines use alternate energy sources such as bio-fuel, solar power; wind power, electric power, stored power, etc. are being developed around the world. However, such engines have many disadvantages. Production of bio-fuel takes vast resources and they still pollute the environment. Similarly, the solar power is not efficient. Added to all, the initial capital and subsequent maintenance costs for machines that use alternative energy sources are very high. Hence, in the absence of a viable alternative, as of now, switching to new technology by changing from traditional Internal Combustion engines has been a great challenge. Magnetism is the basic principle of working for an electromagnetic engine. The general property of magnet i.e. repulsion and attraction forces is converted into mechanical work. A magnet has two poles, a north pole and a south pole. When two like poles are brought together they repel each other and when unlike poles are brought together they attract. This principle is being used in the electromagnetic engine. In this engine, the cylinder head is an electromagnet and the piston head is attached with a permanent magnet. When the electromagnet is charged, it attracts or repels the magnet, in this process it pushes the piston downwards or upwards where in it rotates the crankshaft. This is how power is generated in the electromagnetic engine. It utilizes only repulsive force that allows the field to dissipate completely, and have no resistive effects on the rising piston. The electromagnetic engine should ideally perform exactly the same as the internal combustion engine. The power of the engine is controlled by the strength of the field and the strength of the field is controlled by the amount of windings and the current that is being passed through it. If the current is increased the power generated by the engine also increases accordingly. The current that is used to charge the electromagnet is taken from a DC source like a lead acid battery. The main merits of electromagnetic engine are that it is pollution free. It is easy to design an electromagnetic engine because there are no complicated parts. Since the engine doesnt have combustion, valves, water cooling system, fuel pump, fuel lines, air and fuel filters and inlet and exhaust manifolds and so many other parts that are complicated in an IC engine can be disregarded while constructing an Electromagnetic engine. The main challenge faced in designing an electromagnetic engine is that it has to be as efficient as an internal combustion engine. The main objective of this project is to develop pollution free engine which fulfil the fuel requirement. The working principle of electromagnetic engine is based on magnetic attraction and repulsion phenomenon i.e. magnetic repulsion between same pole and attraction between different poles. This principle moves piston Top dead centre to Bottom dead centre and vice versa. The Electromagnetic Reciprocating Engine uses Magnetic Energy to turn a crankshaft. The Magnetic Energy is used to move the Magnetic Chamber in a linear motion, that motion is converted into a rotating motion by a crankshaft. That crankshaft converts that motion into horsepower and torque with efficiency by using haft strokes. The crankshaft is used to turn an alternator which produces the electricity for the electromagnets in the Magnetic Chamber. The Magnetic Energy is produced by the electromagnets which are powered by electricity from an attached battery. The crankshaft can be connected to a transmission for vehicles.
