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

Russian Rotary Vane Engine
Rotary Vane Engine proposed to power Russian hybrid car 'ё мобиль'
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

VW TSI ENGINE ANIMATION
Following the success of its TDI and FSI engines, Volkswagen is launching
the latest in a line of pioneering inventions with the introduction of TSI
FSI uses the direct injection of petrol into the combustion chamber to
improve efficiency and hence reduce fuel consumption and emissions. Taking
this further, TSI uses -- for the first time ever -- an FSI engine which is
then dual-charged through a combination of an engine driven Supercharger and an Exhaust gas turbocharger arranged in series.
The driving characteristics of the new TSI engine are improved over those
of the current FSI unit. The belt-driven Supercharger operates at the lower engine speeds,
with the turbocharger coming in as
engine speed increases. The result of this is excellent driveability and
performance throughout the range with no turbo lag and high maximum torque.
Key to the TSI's success is that direct injection allows an abnormally high
compression ratio of 10:1 to be used in conjunction with high maximum Boost pressure of up to 2.5 bar
absolute. This enables the relatively small engine to use very high
gearing to provide exceptional fuel efficiency for a petrol engine,
particularly at motorway cruising speeds. As an additional bonus, the TSI
engine provides driver enjoyment, producing high power and torque across a
rev range from 1,000 to 6,500 rpm.
The new TSI engine has a capacity of 1.4-litres (1,390 cc) and produces
either 140 or 170 PS. The 170 PS version has the same peak power as a
conventional 2.3-litre petrol unit but with 20 per cent lower fuel
onsumption, returning 38.2 mpg on the combined cycle. It also produces
impressive torque of 177 lbs ft (240 Nm) from 1,750 through to 4,500 rpm.
All TSI engines drive through a manual six-speed gearbox. A DSG automatic
option is also available with the 170 PS engine. This will be offered later
in the year with the 140 PS unit.
TSI technology has already received international acclaim, having been
named Best New Engine of 2006 in the International Engine of the Year
Awards. It also won the 1-litre to 1.4-litre category.

AIR CAR ENGINE Working Model From The Air Powered Car Concept
AIR CAR ENGINE Working model from the Air Powered Car Concept
Compressed air car Engines with motor replacements done and are now driven
by compressed air, which is stored in a tank at high pressure such as 30
MPa (4500 psi or 310 bar). Rather than driving engine pistons with an
ignited fuel-air mixture, compressed air cars use the expansion of
compressed air, in a similar manner to the expansion of steam in a steam
The Air car Engine can be powered solely by air, or combined (as in a
hybrid electric vehicle with proper motor replacements ) with gasoline,
diesel, ethanol, or an electric plant with regenerative braking.
