Abstract: An engine head assembly includes a plurality of fuel injectors each positioned within a fuel injector bore in the engine head, and each being fluidly coupled with a fluid conduit. Each fuel injector includes a valve assembly positioned within a fuel injector case that includes an elongate body having an opening. A filter sleeve having a particle-blocking perforation array structured to block particles is press fit on the fuel injector case to form a fluid flow path from the fluid conduit into the fuel injector case.

Abstract: A hydraulic piston pump includes a piston disposed in a blind housing bore of a piston housing and that reciprocates to generate a pumping action. To accommodate the piston, a piston cartridge is installed in each of the housing bores. The piston cartridge includes a piston sleeve having an inner sleeve periphery, a first outer sleeve periphery, and a second outer sleeve periphery. The inner sleeve periphery is configured to establish sliding contact with the piston. The first outer sleeve periphery has a first outer sleeve diameter that is larger than a second outer sleeve diameter associated with the second outer sleeve periphery. To seal against the blind housing bore, a liner cap having a cylindrical liner wall and an axial liner cover is disposed over the first outer sleeve periphery. The axial liner cover abuts a housing bore ceiling of the blind housing bore and can receive hydraulic fluid there through.

Abstract: A gaseous fuel engine combines the efficiencies associated with high compression ratio engines with the attractiveness of fueling with natural gas. Each engine cylinder has an associated fuel injector positioned for direct injection and supplied with gaseous fuel from a high pressure common rail. A separate ignition prechamber is also supplied with natural gas and includes an ignition device. Hot gas generated by igniting a mixture of gaseous fuel and air in the prechamber are used to ignite a much larger charge of gaseous fuel injected into the engine cylinder from the fuel injector. The engine has a compression ratio greater than 14: to 1.

Abstract: A cryogenic pump system includes a supply of liquid natural gas, a source of hydraulic fluid, a cryogenic pump, and an electronic control module. The cryogenic pump is operatively arranged with the supply of liquid natural gas and the source of hydraulic fluid. The cryogenic pump is configured to operate using the source of hydraulic fluid to compress at least some of the supply of liquid natural gas for delivery to an engine. The electronic control module is operably arranged with the cryogenic pump and configured to selectively operate the cryogenic pump. Control strategies for operating the cryogenic pump system are disclosed which have reduced power demands.

Abstract: A bearing arrangement for a wobble plate piston pump includes first, second, third, and fourth bearing assemblies. The first and second bearing assemblies support the drive shaft portion for rotation within the housing about the central longitudinal axis, while the third and fourth bearing assemblies support the load plate for rotation relative to the offset shaft portion of the shaft. The second bearing assembly is distally disposed from the first, the third disposed distally to second, and the fourth disposed distally to third. The fourth bearing assembly is the most distally disposed bearing assembly along the shaft.

Abstract: A cryogenic pump comprising a shaft disposed in a bearing. The shaft rotates with respect to the bearing housing, and the shaft includes an end with an angled face. The pump includes a drive at one end of the bearing housing. A tappet passage is formed through the drive housing. A pushrod housing connects to the drive housing. The pump includes a piston and a tappet sliding within the tappet passage. The tappet has a base end disposed within the tappet passage and a rod end extending below the tappet end of the drive housing. A fluid cavity is in the tappet passage between the piston and the tappet. The pump includes a pushrod connected to the tappet. The angled face of the shaft rotates and drives the piston toward the drive housing, pushing fluid within the fluid cavity against the tappet, driving the pushrod away from the drive housing.
