Abstract: An alternative fuel management system may include a base configured for arrangement on a supporting floor or other framework of a vessel and configured to support alternative fuel supply equipment. The system may also include a sealed enclosure sealingly coupled to the base and configured to surround the alternative fuel supply equipment. The system may also include the alternative fuel supply equipment and it may be arranged within the sealed enclosure. The alternative fuel supply equipment may include a high-pressure pump, a fuel filter, a transfer pump, and a high-pressure fuel delivery line extending across the sealed enclosure and configured to provide alternative fuel from the high-pressure pump to a combustion engine. The alternative fuel management system may also include a purge fluid system configured to deliver purge fluid to the combustion engine from a source of purge fluid.

Abstract: A dual fuel system for an internal combustion engine includes a first fuel supply of a liquid pilot fuel, a primary fuel supply of a liquid primary fuel, and a dual fuel injector. The dual fuel injector includes a spill valve fluidly connected with a plunger cavity and movable to control a start of injection and an end of injection, and an admission valve. The admission valve is movable to admit a pilot fuel into the fuel injector, such that the pilot fuel is conveyed through an outlet check to form, within a primary fuel passage fluidly connected to the plunger cavity, a segmented fuel charge of leading pilot fuel and trailing primary fuel by displacing some of the primary fuel. The liquid pilot fuel may be a higher cetane/lower octane liquid fuel, and the primary fuel may be a lower cetane/higher octane liquid fuel.

Abstract: A fuel injector includes an injector housing, an outlet check, an injection control valve assembly, and a valve seat orifice plate integrating a valve seat and various orifices for outlet check control. In the valve seat orifice plate a drain orifice extends between a valve seat surface and a check control chamber formed between a closing hydraulic surface of the outlet check and the valve seat orifice plate. First and second re-pressurization orifices extend between an outer surface of the valve seat orifice plate and the check control chamber.

Abstract: Operating a machine system for co-production of electrical power and filtered potable water includes operating an electrical generator by way of rotation of an engine output shaft to produce electrical power, and collecting water condensed from cooled treated exhaust from the engine for delivery to an outgoing water conduit. Operating the machine system further includes supplying electrical power produced by the electrical generator to an in situ electrical load, and to at least one ex situ electrical load such as a power grid. The in situ electrical load is produced by at least one of an exhaust conveyance device, an air conveyance device, or a water conveyance device in a water subsystem.

Abstract: A manifold for a pump is configured to connect to a jacket to form a reservoir and to connect to at least one pumping mechanism disposed within the reservoir. The manifold includes a first side including a first side surface configured to face the reservoir and a second side including a second side surface. The manifold also includes a bypass passage, at least one push rod guide bore extending through the first side surface and the second side surface, and a leakage passage fluidly connecting the at least one push rod guide bore to an outlet disposed outside the first side surface. The manifold further includes a discharge passage including at least one inlet disposed in the first side surface, and the at least one inlet is configured to receive fluid pumped by the at least one pumping mechanism.

Abstract: A system and method of utilizing engine compression braking technology to create a parasitic load on an engine during initial idling by putting some of the engine cylinders in braking mode while others remain in power mode. Engine compression brakes are operably connected to the engine cylinders. When engine temperature is below a predetermined value, the engine compression brakes for a portion of the cylinders are activated, and those cylinders impose a parasitic load on the engine that rapidly warms the engine.

Abstract: An internal combustion engine system is described herein. The system uses a switching rail in combination with a first fuel rail to operate the internal combustion engine of the system. The first fuel rail receives the first fuel for combustion within one or more of the combustion cylinders of the internal combustion engine. The switching rails are configured to receive either the first fuel or a second fuel. A controller is used to operate a switching valve that, depending on the position of the switching valve, routes or directs either the second fuel or the first fuel from their respective fuel tanks. In a switching condition, such as startup, shutdown, or when the second fuel is not available, the controller can use the first fuel as the alternate source of fuel provided through the switching rail.

Abstract: A fuel injector nozzle assembly includes a two-piece outlet check having a timing control piece and a rate control piece. A nozzle passage is formed between a nozzle body and a two-piece outlet check, and a sac cavity is formed by the rate control piece and the nozzle body and fluidly connects a through-hole in the rate control piece to nozzle outlets. A starting-flow clearance is formed by the rate control piece and the timing control piece, and is opened by moving the timing control piece relative to the rate control piece. Moving the rate control piece relative to the nozzle body opens a main-flow seat. The nozzle assembly provides a slow starting injection rate shape in a common rail or similar fuel system and improved controllability over minimum delivery quantities.
