OTHER
DESIGN DIRECTIONS
The
FRE technology
can be the seed technology for a group of new industries which might
also
be patent protected industries.
One
such new industry
might evolve to manufacture the liquid fuel vaporization-fuel injection
system, particularly if the system were patented.
Although
major
aspects of this technology might be anticipated by fuel handling and
processing
systems in the rocket and jet engine arts, and unpatentable; innovative
improvements in such systems as applicable to FRE may be patentable.
Another
such industry
might evolve to produce FRE combustion monitoring and control devices.
Unlike
the cylinder
heads of reciprocating engines, the face surface at each VVC in a FRE
is
free of obstructions; therefore, sensors to monitor the combustion
processes
in each VVC can be mounted on the face surface at each chamber.
The
sensors and
their output can then be used in a patentable manner to enhance the
efficiency
of the FRE, and/or its fuel, and/or its intake air, and/or its exhaust
handling.
Other
new and
patent protected products (industries) unique to and resultant FRE
development
might evolve from design work to develop:
low inertia
partitions,
annular
cavity
circumference flow limiters,
partition
slot
flow limiters,
hydraulic
partition
pivot bearings,
hydraulic
main
bearings,
rotor
fuel pumps
and fuel feed systems (and fuel mixing?), and
rotor
cam lubricant
application systems, among others.
MARKETS
FRE
of one design
or another are applicable where other types of IC engines are in use
today.
The
simplicity
of the very low pressure FRE and its compatibility to gaseous fuels
such
as natural gas, and propane, etc. makes it attractive for use in a home
electric generator.
In
addition, the
electric generator FRE exhaust can be used to fire one of today's
admirably
efficient boilers for heat and hot water.
Thus
an efficient
gas fired home utility unite which supplies not only heat and hot water
but also electricity seems more then feasible and at an energy cost
comparable
to that required for just hot water and heat.
Higher
compression,
more efficient, FRE are likewise so applicable; however, their use
would
entail a much larger initial investment.
