This document presents information on a magnetic repulsion permanent engine (MRPE). It consists of 3 sentences: The MRPE works by using repulsion and attraction forces between permanent magnets and a ferromagnetic plate to push and pull magnetic pistons inside cylinders, replacing the combustion process of a traditional engine. It describes the basic components, including the magnetic pistons, cylinder, flywheel rod, repulsion-attraction plate, and control electronics to synchronize piston movement. The document outlines the working principle, operation cycle, speed control, and advantages over fossil fuel engines, such as being fuel-less, low maintenance, and environmentally friendly.

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.

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.
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.

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

-shape
-magnetization
-orientation
-separation of the magnets.

8.  Magnetic Attraction of Like Poles
 Possible when a ferromagnetic plate is used.

9. 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.

10.  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

11.  Pushed-in operation cycle
 Starts when Pistons are at BDC.
 Crankshaft moves from 180 to 360 .

12. 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.

13.  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.

14.  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.

15.  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

16.  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.

17. 
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.

18. 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.

19. 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.
