A method includes initializing an estimated fuel property associated with a fuel of an engine system. The method also includes determining an estimated quantity associated with operation of the engine based on a model. The method also includes receiving a signal indicative of a measured quantity…
A hydrogen concentration calculating process calculates a hydrogen concentration in a specific portion of a target region based on an operating state of an internal combustion engine. The internal combustion engine uses hydrogen as fuel. A downstream passage is a portion of an intake passage of the…
A method (50) includes receiving (54) a fuel composition analysis, deriving (56) a fuel index based on the fuel composition analysis, deriving (60) a control adjustment for a gas engine based on the fuel index, and applying (62) the control adjustment to an actuator of the gas engine.
A system for determining a quality of natural gas includes a fuel line (42) for communicating natural gas to an engine (22). An infrared light source (54) is disposed along the fuel line (42) and is configured to emit a beam (50) of infrared light into the fuel line (42) having a wavelength of 6 to…
An object of the present invention is to provide a technology with which when a gaseous fuel is supplied into a fuel tank of a vehicle with an internal combustion engine that uses gaseous fuel, properties of the supplied gaseous fuel can be determined promptly. To achieve the object, the fuel…
The method involves determining the possibility of occurrence of knocking by sensor, such as methane number sensor (2) and knock sensor (6), and recirculating cooled exhaust gas during occurrence or possible occurrence of the knocking. The knock sensor is provided for sensing the occurrence of…
A hydrogen fueling nozzle (20) comprises housing having a portion that is adapted for coupling to an opening of the container, and sensor(s) (100) that is positioned inside the nozzle. The sensor is for detecting the concentration of hydrogen and emitting a signal indicative of the concentration of…
