PAUT MOTOR-REVOLUTIONARY ENGINE.wmv
PAUT ENGINE -
Prototype 2 is performed as an engine with two-sided pistons, positioned
at 90° to each other, in combination with PAUT two-stroke cycles (fig 1).
Such construction provides an engine containing less assembling parts,
having smaller mass to power and overall-dimensions to power ratios, which
are the presumptions for a successful product to be accomplished and for
low cost production/exploitation to be expected. Smaller mass, compared to
the prior art engines, derives from the fact that PAUT engine contains
considerably less assembling parts lacking elements such as: rods,
camshafts, camshaft's driving parts, some valves, large heads.
The very construction of the two-sided piston (fig 3) has more
advantages. Contact area between two-sided piston and cylinder is
considerably larger compared to prior art pistons. Hence, specific
pressures are lower and since the two-sided piston is lubricated under the
pressure, the friction is considerably smaller, the more so as we know that
normal force Fn in the engine center equals zero (fig 2a).
All these results with less wear of the piston and the cylinder. Such a
two-sided piston has considerably smaller mass compared to the prior art
assembly it replaces, consisting of two pistons with their prison-shafts
and two belonging rods, resulting in lessening of linear motion inertial
This construction has still more advantages as compared
to prior art engines such as:
- better controlled cooling of cylinders not being adjoined to each other
- smaller friction inside the engine due to less moving parts
- increasing the capacity of this engine, though considerably, results in
overall dimensions to increase only slightly
- gravity center is posted lower (it is in the engine center)
- better forces configuration in the very engine, while negative forces and
torques nullify each other completely (fig 2b)
- it is possible to dismount pistons and cylinders without entire
dismounting of the engine
- no special tools nor machines were used to produce this engine
- there is less noise due to the design of the two-sided piston
- though the cycle is of two-strokes, the lubrication is performed as if it
The objections on this construction should be as follows:
- due to the compressed construction , the starter should be mounted on the
gear box, but with some endeavour it is possible to mount it on the very
- the force on the output journal of the crankshaft (fig 2a) is twice
compared to the one at prior art engines, but this problem becomes
negligible with a proper design of the journal and of the operating shaft
- there is no oil sump at this engine, hence an additional oil-pump is
- since it is a two-stroke cycle engine, the engine cylinders are submited
to higher mechanical and thermical load comparing to four-strike cycle

World smallest V12 engine
Apparently the builder's name is Yesus Wilder and he only used three
materials to build the engine. Stainless steel, aluminum, and bronze.

Two 9 Cylinder Radial Engines - Start and Run - Sternmotor
Der erste Ausschnitt aus meiner DVD Stationärmotorentreffen Burkhardtsdorf
2011 ( 50 Miinuten, siehe Homepage )
Start und lauf von zwei Sternmotoren.
Zuerst läuft der kleinere Wilga Sternmotor mit 10L Hubraum.
Anschliessend wird der Antonov Sternmotor mit 30 Litern Hubraum und 1000PS

Lautstärke ist unvorstellbar!
First start a Wilga Radial Engine. After this run comes the Antonov Star

The Libralato engine is potentially the best small engine in the world; an
eco-engine for the 21st century. The asymmetrical rotary engine is
exceptionally compact, powerful, efficient, low emissions, low production
and maintenance costs, low vibration and low noise. The engine is ideally
suited for use as an onboard generator for the next generation of Range
Extended Electric Vehicles (REEV) currently being developed by major
manufacturers around the world, but is also suited for a wide range of
mobile generator sets and other small engine applications. For more

This is a powerful rotary internal combustion engine. When rotor round one
time, engine work six times.My mechanical design aim was to create a power
for UAV,MAV, robotics, mini-generators; engine size is very small, can be
forged or EDM etching method of mass production. Because the rotor around
its axis, uniform rotation, so it can reach a very high speed, high power.
Currently, power machinery, achieve practical machine are wankel engine,
RCV engine, and there is a traditional four-stroke internal combustion
engines, two-stroke internal combustion engine, and so on. They have their
advantages, but also have their shortcomings. Especially the mechanical
size less than 1 cm, the disadvantages of exposure of particularly, RCV
engine, the traditional four-stroke internal combustion engine and
two-stroke engine with considerable difficulty processing, especially tiny
part of the process is more difficult, the production cost is very high,
the work reliability was really bad. Wankel engine's parts relatively few,
small size relative high reliability, but cutting machining is difficult,
difficult to implement low-cost lot size
Production.while my engine rotor and stator's face is an irregular surface,
machining difficult too, but the face is smooth, in small size, available
material in plastic processing technology for low-cost of production and
the use of plastic processing methods are forging, EDM etching, forging
will not only enable low-cost production quantities, but also can improve
the mechanical parts of the structure, part of the strength and surface
finish. Adopting EDM etching, can improve parts of sealing and wear
resistance, the specific method is: etch out a lot of fine grooves on the
moving parts which need sealing, forming the labyrinth, with labyrinth
seals, improve sealing performance. and on the sliding contact surface,
etching a lot small pits, lubricants, as far as possible remain in these
areas, to improve the machinery lubrication performance.
study the 3D images that I upload on to forums, that structure, you should
understand that was not possible work, because the rotor projecting too
sharp, not only the room's sealing cannot be guaranteed, and the normal
rotation of the rotor cannot be guaranteed. There are a lot of problems you
can see, after all, is a previous primary design! If you are interested
Stator and rotor shaft is fixed to a piece of the axis.The angle between
the axis of the rotor and stator.The rotation of the rotor can be
decomposed into two parts.1.Wound stator axis rotation of uniform .2.Around
it's own axis of rotation of the uniform. Speed ratio is 3: (-2). So engine
can be high speed,HIGH POWER. Can you understand? if not,you can see my
Another video !
Rotary Rotational Demonstration
A little video for all those folks that refuse to accept the "3:1"
principle of planetary motion inside the Mazda Rotary Engine.
EDIT: For you people that are hung up on my comment at the end of the
video, I suspect you are probably one of those at which the comment
It never ceases to amaze me how many people will see this video and
continue to argue that there is some other relationship other than 3:1
between the inside and outside worlds of this motor.
