    摘要： An internal combustion engine is provided that enables normal combustion of a lean premixture generated from reformed fuel to be achieved in a wide operational range. An internal combustion engine (1) includes a fuel reformation unit (2) that generates reformed fuel based on liquid fuel and higher in octane rating than the liquid fuel and introduces the generated reformed fuel to an output cylinder. The fuel reformation unit (2) includes a first fuel reformer (2A) that includes a reciprocal mechanism where a piston (22) reciprocates in a cylinder (21), a second fuel reformer (2B) that includes a reformation catalyst, and a reformed gas passage (51) that connects the first fuel reformer (2A) and the second fuel reformer (2B). First reformed gas discharged from the first fuel reformer (2A) is introduced to the second fuel reformer (2B) through the reformed gas passage (51).

    摘要： A required reformed-fuel heat generation quantity (required output cylinder heat generation quantity) is calculated based on a required engine power and the thermal efficiency of an output cylinder (3). An estimated reformed fuel heat generation quantity is calculated based on the molar number of reformed fuel, mole fraction of each gas component in the reformed fuel, and heat generation quantity of each gas component in the reformed fuel. When a value resulting from subtracting the estimated reformed fuel heat generation quantity from the required reformed-fuel heat generation quantity is negative, a fuel reforming operation is not executed, assuming that there is a possibility that surplus reformed fuel may be generated. For example, fuel supply from an injector (25) to a fuel reformation chamber (23) is stopped.

    摘要： A catalytic apparatus for efficient pre-combustion refinement of fossil fuel in vehicular engines, including an elongated outer metal pipe containing an elongated stainless steel inner tube of smaller diameter. The outer pipe is crimped or welded onto the inner tube to create a fuel chamber with connectors for the inflow and outflow of fossil fuel therethrough. The fuel chamber contains at least three catalytic elements each comprised of a different metal selected from the group Au, Cu, Ir, Ni, Pd, Pt, Zn and platiniridium, which may be electroplated small-pore screens. As engine coolant is diverted through the inner tube, excess heat is transferred to the inflowing fuel. The fuel is forced to flow in close proximity to the inner tube for maximum convection, and through the catalytic elements before flowing out through the fuel line to the fuel injectors for more efficient combustion. Also disclosed is a method of pre-combustion fuel refinement consisting of the steps of transferring excess heat from engine coolant through a tube disposed through an inlet and outlet of a fuel chamber. In the chamber the heated fossil fuel is forced through the catalytic elements described before returning to the fuel line for injection and combustion.

    摘要： Fuel tank inerting systems and methods for aircraft are provided. The systems include a fuel tank (202), a first reactant source fluidly connected to the fuel tank (202), the first source arranged to receive fuel from the fuel tank (202), a second reactant source, a catalytic reactor (222) arranged to receive a first reactant from the first source and a second reactant from the second source (220) to generate an inert gas that is supplied to the fuel tank (202) to fill a ullage space of the fuel tank (202), and a back pressure flow restrictor positioned within or along a fuel tank supply line and downstream of the catalytic reactor (222), the back pressure flow restrictor arranged to maintain highpressure operation of the catalytic reactor (222).
