摘要： The hydrogen supply device includes a liquid hydrogen pump that boosts the pressure of liquid hydrogen stored in a liquid hydrogen tank, a vaporizer that converts the liquid hydrogen discharged from the liquid hydrogen pump into hydrogen gas, a pressure chamber that a hydrogen gas that flows out from the vaporizer is filled with and that supplies the filled hydrogen gas to a hydrogen engine, and a pump control unit. The pump control unit controls the discharge flow rate of the liquid hydrogen pump so that the actual pressure in the pressure chamber becomes a target pressure based on the hydrogen flow rate supplied to the hydrogen engine, the actual pressure in the pressure chamber, and the rotation speed of the hydrogen engine. At the same time, the target pressure of the pressure chamber is changed according to the rotation speed of the hydrogen engine.

摘要： Some embodiments described herein relate to a method of operating a compression ignition engine. The method of operating the compression ignition engine includes opening an intake valve to draw a volume of air into a combustion chamber, closing an intake valve, and moving a piston from a bottom-dead-center (BDC) position to a top-dead-center (TDC) position in the combustion chamber at a compression ratio of at least about 15:1. The method further includes injecting a volume of fuel into the combustion chamber at an engine crank angle between about 330 degrees and about 365 degrees during a first time period. The fuel has a cetane number less than about 40. The method further includes combusting substantially all of the volume of fuel. In some embodiments, a delay between injecting the volume of fuel into the combustion chamber and initiation of combustion is less than about 2 ms.

摘要： Operating a gaseous fuel engine system includes combusting a mixture containing a gaseous hydrogen fuel and air in a cylinder of an engine, varying an operating parameter of the engine to which a crown surface temperature of a piston within the cylinder is responsive, and populating a temperature model based on a value of the varied operating parameter. Operating a gaseous fuel engine system further includes operating an oil spray apparatus to spray oil onto the piston based on the populated temperature model, and maintaining the crown surface temperature of the piston between a high temperature limit and a pre-ignition mitigation temperature limit based on the operating of the oil spray apparatus. Related apparatus and control logic is also disclosed.

摘要： Methods and systems are provided for adjusting a location of a fuel injection in response to a substitution rate and a desired EGR flow. In one example, a method may include injecting a first fuel to a combustion chamber via a direct injector positioned to inject directly into the combustion chamber, injecting a second, different, fuel to the combustion chamber via an exhaust port injector positioned to inject toward an exhaust valve of the combustion chamber, and combusting the first and second fuels together in the combustion chamber.
