摘要： Method and apparatus for adaptively adjusting the storage of fuels for use in a fuel blending process. First and second fuels are stored in storage vessels at an initial volumetric fuel storage ratio. A storage controller executes a performance strategy to adaptively adjust at least one storage parameter in response to a predicted or detected change in operating conditions of the system. The performance strategy can include increasing a storage pressure of at least one of the fuels and/or changing a total number of storage vessels used to store the respective fuels. A dispensing mechanism transfers a blended fuel formed from the first and second fuels in accordance with the execution of the performance strategy. The fuels can take a variety of forms including hydrogen (H2), oxygen (O2), hydrocarbons, etc. The blended fuel may be dispensed by a fueling station to a motor vehicle.

摘要： Methods and systems are provided for maintaining combustion stability in a multi-fuel engine. In one example, a system may include first and second fuel systems to deliver liquid and gaseous fuels, respectively, to at least one cylinder of the engine, and a controller. The controller may be configured to supply the gaseous fuel to the at least one cylinder, inject the liquid fuel to the at least one cylinder to compression ignite the liquid fuel and combust the gaseous fuel in the at least one cylinder, and retard an injection timing of the injection of the liquid fuel based on a measured parameter associated with auto-ignition of end gases subsequent to the compression-ignition of the liquid fuel. In some examples, the controller may further be configured to adjust an amount of the gaseous fuel relative to an amount of the liquid fuel based on the measured parameter.

摘要： An engine includes a cylinder, a piston, an ignition device, a rotation sensor, an intake temperature sensor, an intake pressure sensor, and a control device. The ignition device ignites a gas mixture. The rotation sensor measures the rotation speed of a crankshaft. The intake temperature sensor measures the temperature of the gas mixture. The intake pressure sensor measures a first pressure value of the gas mixture. The control device controls the hydrogen equivalent ratio of hydrogen contained in the gas mixture and/or timing of igniting the gas mixture based on the rotation speed, the temperature of the gas mixture, and the first pressure value of the gas mixture.

摘要： An engine including a main fuel injection valve, a pilot fuel injection valve, a liquid fuel supply rail pipe, and a pilot fuel supply rail pipe. The main fuel injection valve supplies liquid fuel from the liquid fuel supply rail pipe to a combustion chamber during combustion in a diffusion combustion system. The pilot fuel injection valve supplies pilot fuel from the pilot fuel supply rail pipe to the combustion chamber in order to ignite gaseous fuel during combustion in a premixed combustion system. The liquid fuel supply rail pipe is disposed at one side of an imaginary vertical plane including an axis of a crank shaft. The pilot fuel supply rail pipe is disposed at the side of the imaginary vertical plane at which the liquid fuel supply rail pipe is disposed.

摘要： A system, method and circuit restricts the amount of a first fuel being provided to a duel-fuel engine, for example a diesel—natural gas engine; wherein a secondary circuit is provided, in parallel, to the circuit formed between the engine control unit, first fuel injector, and ground comprising a dummy load, and a normally closed switch inserted in the first fuel injection circuit; such that when the normally open switch is in a closed state the dummy load provides a resistance to the second sub-circuit, such that a total resistance in the second sub-circuit is equal to a total resistance in the first sub-circuit when the normally closed switch is in a closed state.
