Abstract: An internal combustion engine control device includes a valve closing time calculation unit, a valve closing delay time difference calculation unit that normalizes a plurality of valve closing delay times with a fuel pressure and calculates a valve closing delay time difference, a content rate calculation unit that calculates the synthetic fuel content rate of a fuel stored in a fuel tank based on characteristic data indicating the relationship between the valve closing delay time difference and the synthetic fuel content rate of synthetic fuel contained in the fuel, and a combustion control unit that controls an internal combustion engine such that the exhaust temperature of an exhaust gas discharged from a combustion chamber becomes equal to or higher than a threshold temperature based on the synthetic fuel content rate.

Abstract: Internal combustion engines, including diesel engines, can safely and efficiently operate using alternative fuels by ensuring the emissions system always performs the regeneration process using an appropriate fuel. An electronic control unit that communicates with the fuel delivery system and the emissions control system of an engine inhibits the regeneration activity until an appropriate fuel is present, waits until the regeneration event is completed and then directs the engine to continue operation with the alternative fuel.

Abstract: Operating a gaseous fuel engine system includes conveying hydrogen fuel and hydrocarbon fuel into a cylinder in a gaseous fuel engine for combustion. Operating a gaseous fuel engine system further includes receiving an increased engine power output request, boosting a power output of the gaseous fuel engine by varying a ratio of the hydrogen fuel and the hydrocarbon fuel combusted in the cylinder, and varying an in-cylinder combustion parameter based on the varying a ratio. Perturbation to a performance profile of the gaseous fuel engine is thereby limited. Related apparatus and control logic is also disclosed.

Abstract: Operating a gaseous fuel engine system includes outputting control commands to a first fuel admission valve and a second fuel admission valve to admit, respectively, a gaseous fuel blend containing a gaseous hydrogen fuel (H2), and additional H2, into a gaseous fuel engine. An amount of the additional H2 is determined by way of the respective control command based on a performance target for an engine parameter varying on the basis of a relative amount of H2 in a combustion charge. Related apparatus and control logic is also disclosed.

Abstract: The present invention provides a novel combination of devices to measure and transmit to an electronic controller data pertaining to differential pressures, temperatures, regeneration status, exhaust content, accumulated gas consumption and substitute fuel consumption. The electronic controller compares the data to thresholds; when the controller receives signals indicating these thresholds or limits are met, the controller causes the gas substitution rate to be diminished or set to zero until after-treatments elements are fully regenerated thereby facilitating integration of a mixed fuel system with an application internal combustion engine.

Abstract: A multi-fuel system and a method for supplying one or more fuels to an engine in a vehicle having a multi-fuel system are disclosed. Embodiments may determine a quantity of fuel added to one or more tanks, determine energy content and a mass property for each fuel stored in the tanks and supply one or more fuels from the tanks to achieve an operating parameter of the vehicle. Embodiments may analyze a route and determine, for a segment on the route, whether to supply a first fuel with a first set of characteristics or supply a second fuel with a second set of characteristics. The selection of a single fuel or a mixture of two or more fuels for a segment may be based on cost and/or characteristics related to emissions or power.

Abstract: A vehicle control system and a method of operating thereof may include determining a first ratio at which to operate a vehicle system at a first location along a route along which the vehicle system moves. The first ratio may be based on an amount of a first fuel of a first fuel source relative to an amount of a second fuel of a second fuel source. The vehicle system may be powered by one or more of the first or the second fuel sources. First operational settings at which to control the vehicle system may be determined based on the first ratio between the first and second fuel sources at the first location along the route. Operation of the vehicle system may be controlled according to the first operational settings to move the vehicle system according to the first ratio at the first location along the route.
