3. 1. INTRODUCTION Modified version of the reciprocating engine. Piston is replaced by permanent magnet. Works on the principle of magnetism. Fuel less engine.

4. 2. WORKING PRINCIPLE Principle of Magnetism Magnet is a piece of material that has equal number of poles. pole is the point where all the flux lines meet. Magnets attract when their unlike poles (North-South) are brought near each other. Repel when their like poles (North-North or South-South) are brought near each other. Fig.2: Permanent Magnet

5. Force of attraction or repulsion between two magnets depends on the: .

6. Magnetic Repulsion of Like Poles (External direct force) (Force of repulsion) F increases exponentially as the spacing reduces.  

7. Magnetic Attraction of Like Poles Possible when a ferromagnetic plate is used.

8. 3. OPERATION CYCLE RAT plate operation cycles: Pulled-out. Pushed-in. Piston's position: Farthest position of piston from the crankshaft is TDC or RPE. Closest position is BDC or CSE. Crankshaft moves 360° rotation for every push-pull operation of the RAT plate. First half is repulsion stroke. Second half is attraction stroke.

9. Pulled-out operation cycle Starts when pistons are at TDC. Crankshaft moves from 0 ° to 180 ° .

10. Pushed-in operation cycle Starts when Pistons are at BDC. Crankshaft moves from 180 ° to 360 ° .

11. 4. COMPONENTS Magnetic piston High magnetic strength materials: Neodymium-iron-boron (NdFeB) Samarium-cobalt (SmCo) Covered by a thin layer of non-magnetic material. Cylinder High strength, high resistivity and low electrical conductivity non-magnetic materials Stainless steel Titanium Can be made by integrating both non-magnetic and non-metallic materials.

12. 5.Speed control Speed of the magnetic pistons is directly proportional to RAT plate push pull operation speed. Methods: Vary the frequency. Higher the frequency higher the speed and vice versa. Introduce skip pulses at a particular frequency. Skip pulses put the RAT plate in idle state for the skip duration. Causes the engine to slow down until the next valid RAT control pulse.

13. 6. Advantages over fossil fuel engines Fuel less engine. Easy to design. Less power consumption. No waste production. Less running cost & maintenance free. Environmental friendly, very high efficiency engine. Can work as an automobile engine, aircraft engine, locomotive engine, ship engine, etc.
