If fossil fuels are used in conventional IC engines, then energy density and power output are maintained, but greenhouse gas emissions increase and resource sustainability deteriorates
Solution Approach 1:
The patent changes the fundamental energy source from chemical combustion to nuclear fission by altering the fuel composition parameters. The nanofuel contains fissile material (e.g., uranium-235, plutonium-239) at nanoscale concentrations (e.g., 10^-9 to 10^-6 weight percent) mixed with conventional fuel, enabling nuclear reactions to occur within the IC engine combustion chamber. This parameter change achieves ultra-high energy density while eliminating CO2 emissions since no carbon combustion occurs.
Solution Approach 2:
The invention creates a composite fuel system combining conventional fossil fuel or hydrocarbon-based nanofuel with nanoscale fissile material particles and neutron moderator molecules. This composite structure allows the fuel to serve dual purposes: providing base energy through conventional combustion while enabling nuclear fission reactions that dramatically increase energy density and eliminate greenhouse gas emissions. The composite nature allows flexible composition tuning to balance energy output and emission reduction.
2Use of energy by moving object
If nuclear fuel is used to achieve high energy density, then energy output increases, but device complexity and safety requirements increase
Solution Approach 1:
The patent merges nuclear fission technology with conventional IC engine architecture by integrating nanoscale fissile material into the existing fuel delivery and combustion systems. The nanofuel injection system uses modified conventional fuel injectors to deliver nanoscale fuel particles containing fissile material. The combustion chamber design remains fundamentally similar to conventional engines, requiring minimal structural changes while achieving nuclear energy release. This merging approach avoids the complexity of entirely new nuclear reactor designs.
Solution Approach 2:
The invention introduces neutron moderator molecules (e.g., deuterium, heavy water, or boron-containing compounds) as intermediaries to facilitate controlled nuclear fission reactions within the IC engine. These moderators slow down neutrons produced by fission to sustain the chain reaction at low power levels appropriate for IC engines. The intermediary role of moderators enables precise control over reaction rate and energy release, simplifying the overall system control compared to direct high-power nuclear reactions.
