such new industry
might evolve to manufacture the liquid fuel vaporization-fuel injection
system, particularly if the system were patented.
aspects of this technology might be anticipated by fuel handling and
systems in the rocket and jet engine arts, and unpatentable; innovative
improvements in such systems as applicable to FRE may be patentable.
might evolve to produce FRE combustion monitoring and control devices.
heads of reciprocating engines, the face surface at each VVC in a FRE
free of obstructions; therefore, sensors to monitor the combustion
in each VVC can be mounted on the face surface at each chamber.
their output can then be used in a patentable manner to enhance the
of the FRE, and/or its fuel, and/or its intake air, and/or its exhaust
patent protected products (industries) unique to and resultant FRE
might evolve from design work to develop:
circumference flow limiters,
and fuel feed systems (and fuel mixing?), and
application systems, among others.
of one design
or another are applicable where other types of IC engines are in use
of the very low pressure FRE and its compatibility to gaseous fuels
as natural gas, and propane, etc. makes it attractive for use in a home
electric generator FRE exhaust can be used to fire one of today's
efficient boilers for heat and hot water.
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
to that required for just hot water and heat.
more efficient, FRE are likewise so applicable; however, their use
entail a much larger initial investment.
