For the internal combustion engine designer and enthusiast to comprehend the principles of the NELSON
FLYWHEEL POWER PLANT they must first admit that their beloved engine was born, in 1870, with a critical birth
defect, it had great difficulty in breathing and, after 135 years, the only solution has been to try to
give the poor thing super charges of air, when what it really needed, like your asthmatic grandad, was some
The failure to recognize this started engineers down the wrong path, which they have followed
To get enough oxygen for combustion they resorted to compressing air and to make an automatic
cycle they designed a crankshaft that would compress air and fuel mix and convert the expanding products of combustion
to rotary power. The fallacy of this is the throw on a simple crankshaft limits the expansion, resulting
in very high exhaust temperatures, which determines the efficiency of the cycle.
The Carnot cycle, the
basis for all heat engines and the Joule - Thomson laws of thermodynamics show that for a system to reach
the point of converting 100% of the heat, it would have to expand a ratio of 1:273. All ICE's, including
the Wankel, suffer from this heat loss and incomplete combustion.
Rockets, explosive propellants and
the NELSON / TYWA FLYWHEEL POWER PLANT require no compression AND THEREFORE, NO EXPANSION LIMITING CRANKSHAFT.
Instead, the pressure is expanded through a fixed turbine, converting most of the heat in to work, rotating
the mass of the engine, which stores unused torque in each power cycle, as a flywheel. The unrestricted
expansion substantially lowers exhaust temperatures and dramatically increases fuel efficiency.
The power take-off is a hydraulic variable flow/pressure type pump / motor comparable to an electric
motor /generator . The engine mass is rotated by the combustion / power cycle of the engine and only fires
when the rotation drops below a set rpm and stops firing when a safe rpm is reached (600-2,000). At 2,000
rpm the engine / flywheel has stored 200,000 ft#'s of energy (similar to a huge battery pack or steam boiler but
without the inherent added weight they require) so theoretically you could take 200 ft #'s to drive
your vehicle for 1,000 sec.s Of course friction and other mechanical losses would reduce this time by 30-40%.
These mechanical losses would slow and finally stop the rotation when no power is added or a simple
braking system would stop the rotation.
Many factors enter into this tremendous loss of energy.
mechanical accounts for much, but the major loss is in the incomplete combustion, which occurs at even low rpm's
but increases substaintialy as rpm's increase. Pure oxygen gives complete combustion but reciprocal engines can
not handle even a modest oxygen enriched fuel mix. Contrary to a conventional ICE, that must rapidly dissipate
heat, the NELSON FLYWHEEL POWER PLANT thermally traps most of the heat energy, converting
and storing it through the flywheel effect.
Practical applications of the NELSON / TYWA FLYWHEEL POWER PLANT,
beside auto/truck are heavy equipment that spend > 30% of their operation backing up or no load and electric
generators that must be oversized to accommodate start-up loads and surges, ships and pleasure craft need
fuel economy but they can benefit also by utilizing the inherent gyroscopic forces as a stabilizer.
