摘要： An internal combustion engine system is described herein. The system uses a reactor to create pilot fuel from the primary fuel to assist in the ignition of the primary fuel. The system uses one or more heaters to increase the temperature of the primary fuel to an operational temperature of a reactor used to convert the primary fuel in a dehydration reaction. The heaters use waste heat generated by the operation of the engine. The waste heat can be lubricant used to remove heat from components of the engine as well as heat from the exhaust of the engine, for example. A controller is used to maintain an operational range of a level of the pilot fuel in an accumulator. The accumulator acts as a buffer to allow the engine to continue to receive the pilot fuel during dynamic and changing conditions of the engine.

摘要： An internal combustion engine in which when the gas temperature of a fuel reformation chamber when a piston in a fuel reformation cylinder reaches the compression top dead point is estimated to be equal to or higher than a soot generation lower limit temperature set according to an equivalence ratio of the fuel reformation chamber, a reaction gas temperature adjusting operation for suppressing or reducing an increase in the reaction gas temperature in the fuel reformation chamber is executed. Further, a closing timing of an air-intake valve is changed to reduce an effective compression ratio of the fuel reformation chamber.

摘要： An internal combustion engine includes a combustion chamber. The chamber includes a body that is movable in the chamber to vary the chamber volume and contains a catalyst. First valving is operable to admit an intake gas into the chamber and second valving connected with an aqueous fluid supply system is operable to admit an aqueous fluid and a steam reforming fuel into the chamber. A controller is configured to cause the second valving to admit a aqueous fluid and an amount of the steam reforming fuel into the chamber and when a predetermined condition exists in the chamber during compression of the intake gas to absorb heat generated by the compression of the intake gas in the presence of the catalyst to promote a steam reformation process to separate hydrogen from the steam reforming fuel or the aqueous fluid.

摘要： An internal combustion engine in which 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. 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, a fuel supply from an injector to a fuel reformation chamber is stopped.

摘要： Fuel efficiency in a combustion engine is increased by treating the fuel in a reaction chamber prior to delivering the fuel into the combustion chamber of the engine. The method includes the step of entraining a stream of exhaust gas to travel upstream through the reactor chamber in a first flow pattern. The method also includes the step of entraining a stream of fuel to travel downstream through the reactor chamber in a second flow pattern, where at least one of the first and second flow patterns comprises a structured turbulent flow.

摘要： A fuel reformer includes a reforming-fuel injection valve and a fuel reformer catalyst disposed in an EGR pipe and performs a catalyst recovery control when a preset fuel cut execution condition is satisfied. In the catalyst recovery control, a fuel reforming capacity of the fuel reformer catalyst is recovered by stopping an injection of a main fuel and an injection of a reforming-fuel, while supplying additional air to the catalyst by maintaining both of an EGR valve and a throttle valve in a valve open state. Further, in the catalyst recovery control, temperature and a carbon deposit amount of the fuel reformer catalyst are estimated or detected based on which of an opening of the EGR valve and an opening of the throttle valve are adjusted. As a result, fuel reforming capacity is recovered without decreasing a fuel consumption rate improvement effect and a worsening of exhaust emission or drivability.

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.
