摘要： Various embodiments of systems and methods for a smart hydrogen injection controller are disclosed herein. The system produces hydrogen and oxygen from a Proton Exchange Membrane (PEM) electrolyzer and injects these gases individually into a combustion engine using port injection or direct injection at each cylinder of the combustion engine. In one aspect, varying the ratio of hydrogen to oxygen works to improve the operation of the internal combustion engine to decrease emissions and increase combustion efficiency.

摘要： The present invention relates to a zero emission propulsion system and generator sets using ammonia (NH3) as fuel for engines and power plants such as steam boilers (5) for steam turbines (7), piston engines (9), fuel cells (10) or Stirling engines (11). Due to the poor flammability of ammonia (NH3), a hydrogen reactor (4) can split ammonia (NH3) into hydrogen (H2) and nitrogen (N2). The hydrogen (H2) can be placed in a hydrogen tank (8) for intermediate storage and the nitrogen can be stored in a nitrogen tank (6). The hydrogen (H2) could be mixed with ammonia (NH3) to improve flammability and thus facilitate the ignition of an air/ammonia (NH3) mixture in engines or power plants (5, 9, 11). Alternatively, hydrogen (¾) may be supplied in a separate fuel system (5-1, 9-5, 11-8) as a pilot fuel for pilot ignition of an air/ammonia (NH3) mixture. The hydrogen (H2) can also be used in AIP systems along with oxygen (O2) from an oxygen tank (22). The hydrogen (H2) will then be used for fuel cells (10), for combustion in a steam turbine inlet/high pressure side (7-1), or in a Stirling engine (11). In addition to hydrogen (H2), other bio and fossil fuels from the fuel tank (12) can be used as pilot fuel for pilot ignition of an air/ammonia (NH3) mixture. The advantage of using existing bio or fossil fuels for pilot ignition is that engines or power plants (5, 9, 11) will have a pilot fuel system with sufficient capacity to maintain normal operations if ammonia (NH3) is not available. Alternatively, that engines or power plants (5, 9, 11) have an additional fuel system for existing bio or fossil fuels in order to maintain normal operations if ammonia (NH3) is not available. The nitrogen (N2) in the nitrogen tank (6) can be used as a gas in fire extinguishing systems or for submarine ballast tank blows.

摘要： A system for reducing polluting emissions of diesel engines includes a hydrogen gas generator that mixes the hydrogen gas with diesel fuel during certain operations phases of the engine. A default program mixes no hydrogen gas with the diesel fuel. A first operational program, during a cold start, mixes the hydrogen gas and diesel fuel in a 1:1 ratio. A second operational program, during a stabilization phase, mixes the hydrogen gas and diesel fuel in a 1:3 ratio. A third operational program, during a hot start phase, mixes the hydrogen gas and diesel fuel in a 1:2 ratio.

摘要： A system for providing ultraviolet treatment of volatile organic compounds (VOCs) is disclosed. The system can include a first gas conduit to carry a stream of gas having VOCs and a second gas conduit to carry a second stream of gas containing a partial pressure of water vapor. A gas treatment unit can be coupled to the first gas conduit and the second gas conduit. The gas treatment unit can form hydroxyl radicals from the water vapor in the stream of gas carried by the second gas conduit and inject the radicals in the first gas conduit to decrease the presence of the VOCs. The gas treatment unit can include a photocatalyst component and at least one ultraviolet radiation source to irradiate the photocatalyst component with ultraviolet radiation. To this extent, the irradiated photocatalyst component disassociates the gas containing the water vapor to form the hydroxyl radicals.
