Abstract: A low or no pollution engine is provided for delivering power for vehicles or other power applications. The engine has an air inlet which collects air from a surrounding environment. At least a portion of the nitrogen in the air is removed using a technique such as liquefaction, pressure swing adsorption or membrane based air separation. The remaining gas is primarily oxygen, which is then compressed and routed to a gas generator. The gas generator has an igniter and inputs for the high pressure oxygen and a high pressure hydrogen-containing fuel, such as hydrogen, methane or a light alcohol. The fuel and oxygen are combusted within the gas generator, forming water and carbon dioxide with carbon containing fuels. Water is also delivered into the gas generator to control the temperature of the combustion products. The combustion products are then expanded through a power generating device, such as a turbine or piston expander to deliver output power for operation of a vehicle or other power uses.

Abstract: A system and method is provided in the form of an injector assembly 10 for thoroughly premixing fuel and oxidizer reactants and water upstream of a combustion chamber 12. The assembly includes a housing 20 that has a first stack 30 for thoroughly mixing reactants from an oxidizer source 40 and a fuel source 50. It also includes a second stack 80 for mixing and blending the prior mixed reactants with coolant water, before ignition within a combustion chamber 12. The mixing and blending is accomplished in mixing cups 100 where the water and reactant mixture are joined in perpendicular flow streams. Some water is also introduced tangentially in the mixing cups to promote vortical flow and further enhance the mixing process. An alternative injector assembly 210 is also provided that mixes the reactants in a swirl cup 260 and enhances mixture ratio uniformity by means of a diffusion plate insert 270.

Abstract: A gas generator is provided for generating gas including steam and carbon dioxide from the combustion of a hydrocarbon gas with oxygen. The gas generator includes an enclosure with an induction head (201) having an oxygen inlet and a fuel inlet therein, an adapter block (202) to which the induction head (201) attaches and a mixing chamber (203) to which the adapter block (202) is attached. The fuel and oxygen enter the enclosure by first passing through the induction head (201). A start up igniter (210) is located within the induction head (201) to ignite the fuel and oxygen mixture within the enclosure. The adapter block (202) includes a shroud extending away from the induction head (201) and which defines a combustion chamber within the enclosure. The fuel and oxygen mixture is combusted within the combustion chamber before passing out of the shroud of the adapter block (202) and into the mixing chamber (203).

Abstract: Pollution-free or low pollution, efficient, large scale electrical power generation systems, using thermal energy from combustion of hydrocarbon fuel are described herein. The pollutant-free hydrocarbon fuel is combusted in a gas generator with pure oxygen or substantially pure oxygen that is free of nitrogen. Water is also injected into the gas generator. The gas generator discharges high enthalpy steam and carbon dioxide which can then be utilized in a variety of applications including driving turbines for power generation. The steam can be recycled into the gas generator or discharged for various uses. The carbon dioxide can be collected for industrial use or discharged.

Abstract: A low or no pollution engine is provided for delivering power for vehicles or other power applications. The engine has an air inlet which collects air from a surrounding environment. The air is compressed through multiple stages of compression with intercoolers between the compressors. The air is then purged of any constituents which have a relatively high freezing point in a scrubber and then expanded in a turboexpander which causes the air to be cooled down to near air liquifaction temperatures. The air is then passed through a rectifier, where nitrogen is removed from the air. The remaining air is substantially entirely oxygen, which is then compressed and routed to a gas generator. The gas generator has an igniter and inputs for the high pressure oxygen and a high pressure hydrogen containing fuel, such as hydrogen or methane. The fuel and oxygen are combusted within the gas generator, forming water and possibly carbon dioxide.
