1. INTRODUCTION  Modified version of the     reciprocating engine. Piston is replaced by permanent magnet. Works on the principle of magnetism. Fuel less engine. Combustion is substituted by a neodymium (NdFeB) repulsive magnetic force. Fig.1: Basic configuration of MRPE

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. Fig.2: Permanent Magnet  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.

 Force of attraction or repulsion between two magnets depends on the: Fig.3: Force of attraction & repulsion -shape -magnetization -orientation -separation of the magnets.



 Magnetic Repulsion of Like Poles  Fig.4: Magnetic Repulsion of Like Poles

 Magnetic Attraction of Like Poles  Possible when a ferromagnetic plate is used. Fig.5: Magnetic attraction of like poles

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.

 Pulled-out operation cycle  Starts when pistons are at TDC.  Crankshaft moves from 0 to 180 . Fig.6: Angular movement of crankshaft during the repulsion stroke

 Pushed-in operation cycle  Starts when Pistons are at BDC.  Crankshaft moves from 180 to 360 . Fig.7: Angular movement of crankshaft during the attraction stroke

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.

 Flywheel rod  Common flywheel rod.  Helps in synchronizing the pistons movement.  Pistons will be at equidistance from the RAT plate at all times.  Helps in effectively managing the combined rotational force.

 RAT Plate Repulsion-Attraction plate. Assists in attracting and repelling the like poles of the magnets. Once attracted, very minimum force must be able to separate the RAT plate from the magnets. Moves back-and-forth in the direction perpendicular to the pistons movement. High permeability ferromagnetic materials:  Iron  Nickel  Cobalt.

 Rat Plate Driver  Meant to insert and remove the RAT plate.  Sources for driving:  Electrical  Pneumatic  Steam powered  Driver types:  Directly driven by a linear driver  Indirectly driven by a reciprocating driver

 TDC/BDC Position Detector  Detects pistons TDC/BDC positions and generates the TDC/BDC pulses.  Required for precise timing and synchronization of the RAT plate movement.  For pulse generation a notch is used.  Operates a pair of switches one at a time when the piston reaches dead centers.  Piston reaches TDC/BDC  TDC/BDC switch operates.

 Central processor  Converts TDC/BDC pulses into the synchronized RAT plate control pulses.  TDC is detected,  Repulsion signal pulls-out the RAT plate.  BDC is detected,  Attraction signal pushes in the RAT plate.  Rechargeable battery  Used to start the engine.  Provide uninterrupted power supply to the control electronics during the operation.  Charged by the onboard electric power generation system.

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.

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.
