  • Publication number: 20220325658
    Abstract: Operating an engine includes moving a piston in a combustion chamber between a bottom dead center position and a top dead center position in an engine cycle. A fuel is injected into the combustion chamber through a plurality of sets of nozzle outlets varied set-to-set with respect to outlet size and spray angle. Spray jets of the injected fuel are propagated in an impingement-limiting fuel spray pattern that is based on the set-to-set variation in outlet size and spray angle so as to limit dissipation of heat from combustion of the injected fuel to material of the engine by way of a thermal barrier coating (TBC) upon a surface of the combustion chamber.

  • Patent number: 11437816
    Abstract: A STATCOM arrangement includes an MMC and a transformer arrangement arranged to be an interface between the MMC and an AC grid. The MMC is connected in a wye topology with a plurality of converter arms, one for each phase of the AC grid, each arm including a plurality of chain-linked converter cells. The transformer arrangement is arranged to interface each of the arms of the MMC with a respective phase of the grid, and arranged to for each of the converter arms produce leakage reactance resulting in reactance in series with the arm which obviates the need for a phase reactor connected in series with said arm.

  • Patent number: 10934966
    Abstract: A combustion control system for a dual fuel engine includes a combustion control unit structured to receive phasing data for combustion of a main charge of gaseous fuel ignited by way of pilot shots of a liquid fuel, output a pilot fueling command based on the phasing data, and output a valve timing command. The combustion control unit is further structured to vary a phasing of combustion of a main charge of a gaseous fuel ignited by pilot shots of a liquid fuel based on an adjustment to at least one of a pilot shot delivery parameter or a valve timing parameter such as intake valve closing timing from a first engine cycle to a second engine cycle. Control of the intake valve timing can be based on a main pilot shot timing error.

  • Patent number: 10268892
    Abstract: A system and related methods for volume dimensioning may be implemented by a smartphone, pad, tablet, or similar mobile computing device configured with a three-dimensional imaging system. The system may recognize the edges and corners of an object and infer its dimensions, from which a volume and dimensional weight can be calculated. The system may utilize the determined dimensions to allocate shipping resources to most efficiently and safely transport a shipment through a supply chain, assess damage to an object, assess the compliance of carry-on baggage to size requirements, and quickly assess the stocking of a retailer's and a competitor's products.

  • Patent number: 9593629
    Abstract: A method for controlling an air-fuel ratio (AFR) in an engine powered by a gaseous fuel having an unknown composition may comprise receiving an assumed gas species composition for the gaseous fuel, and determining an assumed lower heating value (LHV) for the assumed gas species composition. The method may further comprise determining a perceived lower heating value (LHV) for the gaseous fuel based on a perceived gas mass flow and a gas energy flow for the gaseous fuel, and updating the assumed gas species composition until the assumed LHV and the perceived LHV are aligned. The method may further comprise determining a desired AFR and an airflow necessary to provide the desired AFR using the aligned gas species composition and a desired lambda (?), and adjusting an air system controller of the engine to provide the airflow.

  • Publication number: 20140174406
    Abstract: A system associated with an internal combustion engine is disclosed. The system may be configured to inject fuel at a current fuel injection flow rate and to direct exhaust at a current EGR flow rate. A controller may be configured to determine a maximum fuel injection flow rate and a maximum EGR flow rate based on a first and second group of operating parameters, wherein the first and second group may comprise at least common operating parameter including an oxygen-to-fuel ratio limit. Additionally, the controller may set the current fuel injection flow rate to the maximum fuel injection if a fuel injection flow request, associated with a fuel injector, is greater than the maximum fuel injection flow rate and set the current EGR flow rate to the maximum EGR flow rate if an EGR flow request, associated with an EGR valve, is greater than the maximum EGR flow rate.

  • Publication number: 20070154092
    Abstract: A coded image capture and decoding system includes an image capture unit and a host unit which operate to capture image data, generate a plurality of coded images, and, thereafter, to decode the plurality of coded images with a non-dedicated host processing circuitry. The system comprises an image capture unit and a host unit which may be installed together or separately in one or more physical devices. The image capture unit includes an image processor, an image buffer, an optical unit, an image buffer and an interface module. The host unit includes a host processor, conventional hardware and software functions, and an interface module. During a capture cycle, the image capture unit repeatedly captures images from a coded target. When the capture cycle is complete, the image capture unit attempts to interrupt the host unit. The host unit responds to the interrupt when it is available, receives the plurality of coded images over a communication link, and performs decode processing of the coded images.
