摘要： A dual fuel system includes a liquid pilot fuel supply, a liquid main fuel supply, and a fuel injection apparatus. The dual fuel system further includes a fueling control unit coupled with a cylinder pressure sensor and a NOx sensor, and structured to vary, via outputting a fueling control command to a main fuel injection control valve, fuel delivery parameters each on the basis of at least one of a cylinder pressure parameter or a NOx parameter. The fueling control unit compensates via the varying fuel delivery parameters for a change to a liquid main fuel composition such as a change from a first alcohol fuel or blend to a second alcohol fuel or blend.

摘要： A work tool identification system for identifying the work tool attachment attached to a machine from among a plurality of interchangeable work tool attachments utilizes a data transmission device located on the work tool attachment and an electronic machine controller that may be located on the machine. The data transmission device may store work tool identification data and may measure an interval count indicative of the lapsed time since the work tool attachment was initially moved by a machine. The electronic machine controller generates and sorts a work tool identification list of the plurality of work tool attachments based on the interval count with the lowest interval count appearing before any higher interval counts that is indicative of a recently coupled work tool.

摘要： A fluid connector in a fluid joint assembly such as in a machine hydraulic system includes a connector body having a stem with a seal face extending circumferentially around a connector axis at a backup sealing location. A non-metallic seal is upon the stem and extends circumferentially around the connector axis at a primary sealing location. The fluid connector also includes a swivel nut including threads and a snap retainer and supported for rotation upon the stem. The fluid connector can establish a primary sealing state by way of hand installation, and can be torqued to a backup sealing state to provide a robust metal-to-metal seal.

摘要： A ground engaging tip of a tip assembly for a base edge of a ground engaging implement has an adapter configured for attachment to the base edge of implement and having a forwardly extending adapter nose. The ground engaging tip has a rear edge, a top outer surface, and a bottom outer surface. The top outer surface and the bottom outer surface extend forward from the rear edge of the ground engaging tip and converge at a front edge of the ground engaging tip. The ground engaging tip also has a nose cavity, within the ground engaging tip and defined between the converging top and bottom outer surfaces of the ground engaging tip, for receiving the adapter nose therein. The nose cavity includes a wear indicator extending from an inner surface of the nose cavity, into the ground engaging tip, toward the bottom outer surface of the ground engaging tip.

摘要： A first method of protecting an engine and a transmission of a marine vessel during gear shifts and a second method of programming one or more Shift Protection Sequences (SPS) are disclosed. The first method includes receiving a Shift Request (SR) and activating a SPS from among a plurality of enabled SPS. The second method includes configuring a Shift Protection Type (SPT); enabling and configuring a plurality of required and SPS variables; and, optionally, enabling and configuring a plurality of optional SPS variables. The SPT may be a Basic Shift Protection (BSP), which includes time-based SPS; or the SPT may be an Advanced Shift Protection (ASP), which includes alternate time-based and operating-variable based SPS. The SPS of the ASP may be incrementally programmed and added to the BSP.
