NAGY’S ROTOR MOTOR
Terminological note
In the wording of the United States Patent no.: US 10,047,668 B2 awarded on
Aug.14, 2018 to Imre Nagy (HU), there are three expressions denoting the
pateneted device and the method inter-changeably used :
- COMBUSTION ENGINE WITHOUT COMPRESSION ;
- NON-COMPRESSION INTERNAL COMBUSTION ROTOR-MOTOR , and
- NON-COMPRESSIVE INTERNAL COMBUSTION ROTOR-MOTOR
There is yet another option how to name this engine:
- COMPRESSIONLESS INTERNAL COMBUSTION ROTORMOTOR/ENGINE.
To avoid negative labelling, I would suggest to name this type of engine
-
ATMOSPHERIC INTERNAL COMBUSTION ROTOR MOTOR / ENGINE.
Note on phonetics - Pronunciation
Inventor‘s family name is Nagy. This Hungarian word means great, large, big in English. Its proper pronunciation should make no
trouble to speakers of English. Although it is written with four letters, there are only three phonemes N [as N in „Name“], A [as U in
„but“], and GY as the first phoneme in „dew“, usually phonectically transcribed as [dʸu:]. So try to pronounce the name NAGY as a
word written in usual standard English orthography - NUDEW [NADyU], omitting the final phoneme [u]. In linguistics this last
phoneme is oft transcribed as /ɟ/.

NAGY’S ROTOR MOTOR
All data on roto motor provided below
refer to the NRM functional prototype
Nagy‘s non-compressive internal combustion rotor motor
[NRM] resembles an electric motor its external appearance
by. The base block of the engine is of cylindrical shape
whereby its axis is horizontally oriented.
Slide 5/28
NAGY’S ROTOR MOTOR
The NRM combustion/explosion space is shaped as
a perpendicular circular hollow cylinder (cylindrical shell). Its
inner surface is formed by the central/main rotor, while its
outer surface is formed by combustion chamber covers that
are shaped in principle as a cylindrical shell strips.
Slide 6/28
NAGY’S ROTOR MOTOR
These covers are additionally modified in such a way that
they may harbour tube-like, „C” shaped timing rotors. As
there are three covers, so there are also three timing
rotors. These rotors virtually divide the combustion/explosion space in the shape of cylindrical shell into three
equal parts. The angular distance between axes of these
three timing rotors is 120⁰. The covers also harbour fuel
mutiple injection, ignition and exhaust ports.
Slide 7/28
NAGY’S ROTOR MOTOR
The principal gear mounted on the shaft of the main rotor
synchronises the gears mounted on the shafts of three
timing rotors and in this way an unhindered rotation of the
blades mounted on the main rotor is provided as well as
the closure of the combustion chambers by the blade that
is just transversing it
Slide 8/28
NAGY’S ROTOR MOTOR
In the combustion space, designed in the described way
and closed from all sides, there is the air under atmospheric pressure, at each rotation six ideal fuel ignitions/
explosions which release quadrupled energy compared to
combustion technology, take place and the blades mounted on the main shaft – are thus continuously under
pressure of gases generated by the fuel explosion. In this
way the chemical energy of the fuel is converted into
enormous mechanical power with a wide range of torques
at the output. The quadrupled energy extraction provided
by ideal explosion of gaseous fuels under atmospheric
pressure, is exploited with efficiency close to 100%.
DON‘T BE SHOCKED – IT WAS PROVEN BY TESTING!
Slide 9/28
NAGY’S ROTOR MOTOR
The suction of fresh air into the
explosion chambers in rotor
motor is performed by the same
blades mounted on the central
tubular shaft in angular distance
of 180⁰. During their rotation, the
backside of the blades works as
centrifugal ventilator and through
the boreholes in the tubular
shaft, continuously fresh air of
atmospheric pressure but in
large volume blows through the
engine interior.
Slide 10/28
NAGY’S ROTOR MOTOR
Hereby not only the cooling of whole interior space of the
engine is provided, but also the whole combustion space
is filled with fresh air and at the same time the same blade
pushes exhaust gases out of the chamber.

Slide 15/28
NAGY’S ROTOR MOTOR
The prototype has two blades and three timing chambers,
and therefore the timing rotor diameter is ½ of the main
rotor diameter.
Should the timing rotor diameter be 1/3 of the main rotor
diameter, then it would be possible to have 4 combustion
chambers and 3 blades and to perform 12 combustions
per rotation.
Should the timing rotor diameter be 1/4 of the main rotor
diameter, then it would be possible to have 5 combustion
chambers and 4 blades and to perform 20 combustions
per rotation.
Slide 16/28
NAGY’S ROTOR MOTOR
Should the timing rotors diameter be 1/5 of the main rotor
diameter, then it would be possible to have 6 combustion
chambers and 5 blades and to perform 30 combustions
per rotation.
It is self-evident that a rotor motor working with thirty
combustions per rotation would consume 5 time more
fuel, it is also self-evident that it would generate five time
more mechanical power.

Slide 17/28
NAGY’S ROTOR MOTOR
It is self-evident that the rotor motor equipped with multibladed rotors would be able to generated enormously
greater power and torque.
The relation – (number of blades/number of combustion
per rotation) to number of combustion per rotation – is
given and fix. The physical dimensions of mechanical parts
are variable in very broad range and allow for very variable
and easily adjustable design of rotor motor according to the
required service it should provide.
As the inventor says – rotor motor may power any transport
device - from small drone to transocean ship, whereby his
dearest dream is to power an airship with rotor-motor.

NAGY’S ROTOR MOTOR
Nagy’s rotor motor may be designed with a different
number of combustion spaces, which in their turn may vary
in volume depending on the critical parameter - the outer
diameter of the cylinder-shaped engine block. The
diameter of the block may also vary over a wide range.
This almost uncompromised design versatility of the noncompressive rotor motor makes it possible to manufacture
engines with power and torque in unimaginable broad
range and attain an operating efficiency close to 100%.
It makes it a universal propulsion unit with a wide range of
applications in various areas of human activity.

- Low maintenance costs,
and above all
ITS ENVIRONMENTAL
PERFORMANCE
Slide 21/28
NAGY’S ROTOR MOTOR
ENVIRONMENTAL PERFORMANCE OF NRM
Nagy‘a rotor-motor is designed for green gaseous energy
carriers: hydrogen, natural gas, liquefied propane-butane
and biogas. These fuels are suitable for use in the ideal
explosion process at normal atmospheric air pressure
without any additional compression and in this way they
release and utilise up to four times the amount of energy
with almost 100% efficiency.
The NRM makes it possible to substantially reduce
environmental pollution: the exhaust gases released into
the atmosphere contains almost exclusively water
vapor and carbon dioxide.
Slide 22/28
NAGY’S ROTOR MOTOR
APPLICATION FIELD OF NRM
NRM may be installed and replace any type of piston
engine currently being used anywhere.
A. Industrial application - electric power generating
facilities, mobile electric power generators.
B. Transport application – any kind of transport
- on land (road, railway),
- by water (boats, ships, and even submarine), and
last, not least
- by air.
Let us dwell more on air transport.
Slide 23/28
NAGY’S ROTOR MOTOR
It was one of the motives that has driven the inventor
du work on new type of engine – to find a propulsion
for airships. It is conviction that NRM applied to air
transport or flying machines would
- increase the usueful payload due to its small weigh;
- reduce fuel consumption by up to ten times;
- reduce noise level of air transport (no noisy turbines),
- eliminate dangerous heat generated by turbines;
- extend profoundly working life tremendously;
- reduce maintenance costs; and
- principally increase flight security, and above all
- substantially reduce air pollution of higher layers of
atmoshere.
Slide 24/28
NAGY’S ROTOR MOTOR
NAGY’S ROTOR MOTOR IS A TYPE OF AIR-COOLED
ENGINE, THEREFORE IT DOES NOT NEED ANY
ANCILLARY COOLING SYSTEM WITH SOME LIQUID
AS COOLANT.
NRM NEEDS NO OIL AND OIL TANK TO KEEP LUBRICANTS NEEDED FOR TRANSMISSION PARTS AS IT
IS OF NON-PISTON TYPE.
BY THE SIMPLICITY OF ITS DESIGN AND ENERGY
EFFICIENCY, ITS LOW-CARBON PRODUCTION, NRM
WILL BE OR ALREADY BECAME AN ALTERNATIVE
AND SERIOUS COMPETITOR TO OTTO (GASOLINE)
AND DIESEL ENGINES.
Slide 25/28
NAGY’S ROTOR MOTOR
NAGY’S ROTOR MOTOR MAY PROFOUNDLY
CONTRIBUTE TO MITIGATION OF CLIMATE CHANGE
AND WORRIES ABOUT FUELS NEEDED FOR
MODERN INDUSTRIAL SOCIETIES.
NAGY ROTOR MOTOR MAY DRAMATICALLY REDUCE
THE AIR-POLUTION AND THUS TO HELP TO SAV
OUR EARTH.
IT IS THE GREEN ENGINE
FOR OUR BLUE PLANET.
Slide 26/28
NAGY’S ROTOR MOTOR
IT IS INVETORS’S DEAREST WISH TO START AND
RUN PRODUCTION OF THIS MACHINE IN HIS
HOMELAND - HUNGARY. IT DOES NOT MEAN THAT
HE IS NOT INTERESTED IN INTERNATIONAL
COOPERATION.
SHOULD AN INVESTOR BE INTERESTED TO
FINALISE THE EXTENDED TESTING AND
PREPARATION FOR THE MASS-SERIES
INDUSTRIAL PRODUCTION IN COOPERATION THEN THE OPTION OF THE PATENT
SALE WOULD COME IN CONSIDERATION.
