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

M3 Grant Tank - Home for my Radial Engine Beltring 2005
This is where my Radial engine ended up... in an Ex Range Wreck M3 Grant
Tank. The video shows its first outing at the 2005 War & Peace show down
in Kent. "restoration" was by Nick Mead at Tanks-a-lot. SEE Video of
engine running , on my drive, before it went into the Grant
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.
All credits to him.

It never ceases to amaze me how many people will see this video and

Awesome V12 Monster diesel engine Awake and Alive startup
Awesome V12 Monster diesel engine Awake and Alive startup
The first V-type engine (a 2-cylinder vee twin) was built in 1889 by
Daimler, to a design by Wilhelm Maybach. By 1903 V8 engines were being
produced for motor boat racing by the Société Antoinette to designs by
Léon Levavasseur, building on experience gained with in-line four-cylinder
engines. In 1904, the Putney Motor Works completed a new V12 marine racing
engine -- the first V12 engine produced for any purpose. Known as the
'Craig-Dörwald' engine after Putney's founding partners, the engine
mounted pairs of L-head cylinders at a 90 degree included angle on an
aluminium crankcase, using the same cylinder pairs that powered the
company's standard 2-cylinder car. A single camshaft mounted in the central
vee operated the valves directly. As in many marine engines, the camshaft
could be slid longitudinally to engage a second set of cams, giving valve
timing that reversed the engine's rotation to achieve astern propulsion.
"Starting is by pumping a charge into each cylinder and switching on the
trembler coils. A sliding camshaft gave direct reversing. The camshaft has
fluted webs and main bearings in graduated thickness from the largest at
the flywheel end." Displacing 1,119.9 cuin (18,352 cc) (bore and stroke
of 4.875" x 5" (123.8 x 127 mm)), the engine weighed 950 pounds (430 kg)
and developed 150 bhp (110 kW). Little is known of the engine's
achievements in the 40-foot hull for which it was intended, while a scheme
to use the engine to power heavy freight vehicles never came to
fruition. One V12 Dörwald marine engine was found still running in a
Hong Kong junk in the late-1960s.
Two more V12s appeared in the 1909-10 motor boat racing season. The Lamb
Boat & Engine Company of Clinton, Iowa built a 1,558.6 cuin (25,541 cc
(5.25" x 6" (133.4 x 152.4 mm)) engine for the company's 32-foot Lamb IV.
It weighed in at 2,114 pounds (959 kg). No weight is known for the massive
3,463.6 cuin (56,758 cc) (7" x 7.5" (177.8 x 190.5 mm)) F-head engine built
by the Orleans Motor Company. Output is quoted as "nearly 400 bhp (300
By 1914, when Panhard built two 2,356.2 cuin (38,611 cc) (5" x 10" (127 x
254 mm)) engines with four-valve cylinder heads the V12 was well
established in motor boat racing.
In automobiles, V12 engines have not been common due to their complexity
and cost. They are used almost exclusively in expensive sports and luxury
cars because of their power, smoother operation and distinctive sound.
