  • Patent number: 9624851
    Abstract: A method of operating a vehicle powertrain includes determining a selected powertrain operational mode. A demand fraction is determined. An internal combustion engine (ICE) is to output a maximum power when a gaseous fuel is conveyed to an injector of the ICE at a source pressure greater than a cutoff pressure. The source pressure in a container in fluid connection with the injector is determined. The gaseous fuel is received at the source pressure by the injector to inject the gaseous fuel into the ICE for combustion in response to the source pressure, demand fraction, or selected powertrain operation mode meeting a first set of criteria. The injector is prevented from injecting the gaseous fuel into the ICE and the powertrain is driven from an alternative power source in response to the source pressure, demand fraction, or selected powertrain operation mode meeting a second set of criteria.

  • Patent number: 9546604
    Abstract: The present disclosure provides methods, systems, and computer-readable media for the detection of valve faults based on transient air pressure measurements. For example, a method for fault detection may comprise actuating a shut off valve to an open position, determining a first air pressure of air in an enclosed space at a first time, determining a second air pressure of the air in the enclosed space at a second time and in response to actuation of the shut off valve to an open position, subtracting the first air pressure and the second air pressure to obtain an actual pressure difference, comparing the actual pressure difference to a predetermined pressure difference, and determining, based on the transient comparison, whether at least one of the shut off valve and a check valve is in a failed state.

  • Patent number: 9457789
    Abstract: A fuel control module, based on an engine torque request, fuels N cylinders of an engine using a first fuel system. N is an integer greater than zero. A throttle control module, based on the engine torque request and the fueling of the N cylinders using the first fuel system, opens a throttle valve to a predetermined wide open throttle (WOT) position. A cost module, when the engine torque request is greater than a predetermined torque: determines a first cost value for fueling at least one of the N cylinders of the engine using a second fuel system; and determines a second cost value for adjusting at least one operating parameter other than fueling of the engine. An adjustment module, based on, the first and second cost values, one of: initiates the fueling of the at least one of the N cylinders using the second fuel system; and adjusts of the at least one operating parameter other than fueling of the engine.

  • Patent number: 9410499
    Abstract: The present invention is intended to suppress generation of a misfire and an increase in the amount of emission of HC, in a multi-fuel internal combustion engine of compression ignition type using, as fuels, a liquid fuel which can be ignited by compression and a gas fuel which is lower in ignitability than the liquid fuel. In the invention, in the same operating state, in cases where the liquid fuel and the gas fuel are caused to combust with the liquid fuel being used as an ignition source, the equivalent ratio of a mixture in a cylinder is made to increase, in comparison with the case where only the liquid fuel is caused to combust, and the rate of the increase of the equivalent ratio with respect to the case where only the liquid fuel is caused to combust is made smaller, when an engine load is low in comparison with the time when the engine load is high, and when an engine rotational speed is low in comparison with the time when the engine rotational speed is high.

  • Patent number: 9127599
    Abstract: The present invention is intended to suppress an excessive increase in the amount of emission of HC in a multi-fuel internal combustion engine of compression ignition type which is able to perform mixed combustion of a liquid fuel, which can be ignited by compression, and a gas fuel which has methane as a primary component. In the present invention, a required mixing ratio of the liquid fuel and the gas fuel as well as a required amount of HC emission is calculated based on an operating state of the multi-fuel internal combustion engine (S103, S104). Then, based on the required mixing ratio and the required amount of HC emission, a required compression ratio is calculated which is a compression ratio at which an amount of HC emission from the multi-fuel internal combustion engine becomes the required amount of HC emission (S105), and the compression ratio of the multi-fuel internal combustion engine is controlled to the required compression ratio (S107).

  • Patent number: 9127600
    Abstract: An engine system is disclosed that combusts both gaseous and diesel fuels. The system includes a diesel reservoir in communication with an internal combustion engine via a diesel rail. The system also includes a liquefied gaseous fuel reservoir in communication with the internal combustion engine via a gaseous fuel rail. The gaseous fuel and diesel rails both are in communication with a pressure control device. The pressure control device measures the pressure differential between the gaseous fuel and diesel rails. If the pressure differential exceeds a desired range, the pressure control device vents gaseous fuel from the gaseous fuel rail to a spark ignited engine, where the vent gas is used as fuel. The spark ignited engine then converts the vented gaseous fuel to useful work.
