  • Patent number: 10975738
    Abstract: An engine fluid heating apparatus, preventing failure in heating fluid, is provided. A control device opens a sub switch during an initial opening period (“IOP”) after closing a main switch, and the control device closes the sub switch during an initial closing period (“ICP”) after the IOP. Circuit normality is displayed by turning on an indicator lamp when a heater feeding circuit is electrically conducted via a bypass electric circuit during the IOP. Heater feeding is displayed by turning off the indicator lamp when power is supplied to the electric heater via a trunk electric circuit during the ICP. Circuit abnormality is displayed by turning off the indicator lamp when the heater feeding circuit is not electrically conducted via the bypass electric circuit during the IOP, and the circuit abnormality display is held by keeping the indicator lamp off during the ICP immediately after the IOP.

  • Patent number: 10612497
    Abstract: The performance of an automotive gasoline fueled spark-ignited internal combustion engine (ICE) optionally operated with a dedicated exhaust gas recycle system is enhanced by reforming the fuel in the presence of injected water to increase the yield of hydrogen which permits higher compression ratios and suppresses engine knock associated with pre-ignition of the fuel. Reforming can occur (a) in the cylinder with the reaction of a fuel-rich mixture and steam from the water injected into the intake manifold of one or more dedicated exhaust gas recirculation cylinders; (b) in a catalytic reformer located upstream of the engine; (c) in a catalytic reformer located downstream of the engine that receives fuel and the exhaust gas stream from the dedicated exhaust gas recirculation cylinder(s), and returns cooled reformate to the intake manifold; and (d) in a catalytic reformer that receives fuel and the exhaust gas stream from the engine exhaust gas manifold, and delivers reformate to the intake manifold.

  • Patent number: 9689306
    Abstract: A method for supercritical diesel combustion combines fumigation and supercritical diesel fuel combustion to effect greater fuel efficiency and reduce exhaust gas pollutants from a compression ignition engine. The invention utilizes the fumigant method by combining two gases (DME and propane) which autoignite prior to the injection of the liquid diesel fuel. This pre-combustion of the fumigant gases combined with the engine's compression of the combustion chamber gases is managed to attain a supercritical combustion chamber environment into which the liquid diesel fuel is injected. This targeted supercritical combustion chamber environment causes the diesel fuel to become a supercritical fluid prior to combustion, resulting in significantly greater efficiency and negligible exhaust gas pollutants resulting from the combustion of the diesel fuel.

  • Patent number: 8967124
    Abstract: A fuel injector assembly includes a first coil that induces a time varying magnetic field into a second coil that is utilized to heat fuel flowing through the fuel injector. A first coil receives a first signal from a driver to generate a first magnetic field that moves an armature between an open and closed position. The second coil generates a second magnetic field generated by a current induced by the first coil into the second coil. The induced current is generated by an alternating current signal that is interposed onto a direct current signal sent to the first coil. The alternating current signal produces a time varying second magnetic field that induces heating of a magnetically active component with the fuel flow that in turn heats the fuel.

  • Patent number: 8915218
    Abstract: A process and apparatus is provided for burning liquid ammonia in an energy device such as a diesel engine, boiler or gas turbine. In particular, the process and apparatus include mixing a renewable fuel with a low flame speed and high ignition temperature, e.g., ammonia, with a combustible liquid fossil or bio-fuel and supplying the mixture into a closed fuel loop where part is efficiently burned in an engine combustion chamber, and part is used to cool the engine and returned by the loop for mixture with fresh incoming fuel mixture. The invention provides for the mixing and emulsifying in such a way that vapor lock is avoided. In the loop, the mixture is emulsified into a disperse distribution of fuel droplets such that upon injection of a portion into the combustion chamber, the renewable fuel in an emulsified droplet evaporates, mixes with the air and forms a small combustion cell surrounding the liquid fuel droplet.

  • Publication number: 20140318509
    Abstract: A pre-heater system for a combustion engine. The combustion engine uses a liquid fuel and air, and is cooled by a cooling system. The pre-heater system includes a fuel pre-heater. The fuel pre-heater includes a coolant reservoir and a fuel line traversing the coolant reservoir. The coolant reservoir is in a fluid relationship with the cooling system, and the fuel line is in a fluid relationship between a fuel tank and the combustion engine. In some embodiments, the pre-heater system further includes an air pre-heater. The air pre-heater comprises an air box and a coolant line traversing the air box. The air box is in a fluid relationship between the ambient air and the combustion engine, and the coolant line is in a fluid relationship with the cooling system. In operation, the fuel and air is heated before being consumed by the combustion engine.

    Abstract: A fuel system is provided including a diesel fuel reservoir configured to supply a diesel fuel having a first amount of dissolved oxygen. An advanced diesel engine is arranged generally downstream from the diesel fuel reservoir. A deoxygenation system has an inlet fluidly coupled to the diesel fuel reservoir and an outlet fluidly coupled to the advanced diesel engine. The deoxygenation system is configured to remove dissolved oxygen from the diesel fuel. The diesel fuel provided to the advanced diesel engine has a second amount of dissolved oxygen. The second amount of dissolved oxygen is less than the first amount of dissolved oxygen.

  • Patent number: 8794217
    Abstract: 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.

  • Publication number: 20140190457
    Abstract: Free heat or scavenged heat from the coolant system or circulating oil from the crankcase of an internal combustion engine supplies heat to a fuel pre-heater causing the liquid fuel to become superheated and partially vaporized. Liquid fuel preferably diesel is converted from a fluid at ambient temperature to a superheated fuel breaking down the hydrocarbons bonds of the fuel (cracking) before being sent directly to the fuel injectors. Water fog may be added to the air intake manifold. Catalysts inside the fuel preheater also aid in breaking down the fuel (cracking). The fuel pre-heater also operates as a coolant/oil filter to remove debris and sludge from the circulating coolant water or circulating crankcase oil of an internal combustion engine. Fuel efficiency has repeatedly been tested to increase 20% or better with highway driving. Exhaust emissions have been tested to show 20% or more reductions in greenhouse gases.
