12 Rotor Engine Running- Different Angles
Watch the last part of the video where there is a glass of water on the
engine. The engine runs so smooth it does not even ripple the water.
Looking at the glass on the back, you are seeing the reflection of the Exhaust tubes bouncing on the flat
surface of the water. The water actually does not even have a ripple.
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

Rotary Engine Breakthrough?
The Wankel engine always held out a lot of promise, but never was able to
fully deliver on those promises. It was never very fuel efficient, and the
Exhaust temperatures were very high.
But now an independent car tech thinks he has stumbled onto what held that

Russian Rotary Vane Engine
Rotary Vane Engine proposed to power Russian hybrid car 'ё мобиль'
Handbuilt 4-Rotor Engine
This was a project that took about five years of weekends to put together.
There was a lot of trial and error as jury-rigged parts were improvised and
revised, leaks were identified and plugged, and byzantine electrical
diagrams were decoded. It still does not run smoothly, as there likely is
a problem with the intake system that has prevented smooth timing at idle.
But she runs!
lots of people wanted to know where the E-shaft came from: it was custom
ordered from a shop in New Zealand.
