Abstract: A blowby disposal system for disposing of blowby contaminants from a blowby mixture contained within a crankcase chamber of an internal combustion engine includes an air-oil separator, a passage to transport the blowby mixture from the crankcase chamber to the air-oil separator, a pump, and a passage to transport the blowby contaminants from the air-oil separator to the pump. The pump directs the stream of contaminants into the exhaust system of the engine where it becomes a portion of the overall exhaust emission stream. Degradation of the engine components and the turbocharger components is reduced because the blowby contaminants are not introduced into these components through the air intake system.

Abstract: An integral fluid pump is disposed in the cylinder head of an internal combustion engine is directly driven by an engine piston and provides fluid flow to a fluid system. First and second check valves are connected to the cylinder head and control fluid flow between a reservoir, the fluid pump, the fluid system. The integral fluid pump is particularly suited for providing fluid flow to an engine lubricating system.

Abstract: A jumper tube assembly connects a fluid supplying port of a fluid passing member to an inlet port of a fuel injector and passes fluid flow between the fluid supplying port and the inlet port. A tubular conduit of the jumper tube assembly is connected at a first end portion by brazing to a sealing member has a configuration sufficient to absorb a fluid applied load and provide a leak resistant joint at the inlet port to the fuel injector. The jumper tube assembly is particularly suited for use in a fuel injection system of an internal combustion engine.

Abstract: A system and method for automatically controlling the position of a work implement movably connected to a work machine and maintaining the work implement at a preselected slope of cut relative to a geographic surface is provided. The system has first and second receiving devices mounted on the work implement for receiving position signals from a plurality of remote locations. A processor determines the actual slope of cut of the work implement based on the received position signals. An implement controller delivers an implement control signal in response to a difference between the actual and a preselected desired slope of cut of the work implement. An implement control system elevationally changes the slope of cut of the work implement at an automatic mode of operation of the system. The system is particularly suited for use on a geographic surface altering work machine.

Abstract: A method of engine compression braking for an internal combustion engine is disclosed wherein the engine is converted to a two-cycle mode for braking. Exhaust valves are opened in cylinders wherein associated pistons are near top dead center and substantially simultaneously, exhaust valves are opened in cylinders wherein associated pistons are nominally past bottom dead center. The method results in an advantageous braking power increase due to back-filling of the cylinders wherein the pistons are nominally past bottom dead center. A similar method is disclosed for use during four-cycle braking.

Abstract: A self flushing centrifugal pump has a fluid flushing passageway disposed in a housing of the pump which directs flushing fluid flow from a volute passageway in the housing of the pump near an outlet port of the pump to a chamber in the pump near a pump shaft seal and from the chamber to an inlet port of the pump via apertures in the impeller of the pump in response to rotation of the impeller.

Abstract: A cooling air system for an internal combustion engine has an engine enclosure and a plenum connected to the engine enclosure. A radial flow fan disposed in the plenum has blades which are spaced from the side wall a preselected distance. An inlet duct in the engine enclosure directs drawn outside ambient air toward a radiator located within the engine enclosure. A shroud extending into the plenum directs air flow passing through the radiator axially toward the radial flow fan. An outlet opening at the top end of the plenum exhausts radially directed heated air flow elevationally to the atmosphere.

Abstract: Adjustment capabilities are useful in gearing mechanisms so that backlash settings between gears may be changed to accommodate for normal operation, wear, or maintenance disturbances. The subject backlash adjustment mechanism allows for adjustment of center distances between an adjustable idler gear (23) and a camshaft gear (24), while providing a geometric alignment (47,82) relationship to maintain a substantially fixed center distance between the adjustable idler gear (23) and another mating gear (22). The subject backlash adjustment mechanism (26) has the adjustable idler gear (23) rotatably mounted on an idler gear mounting (31,58) having a slotted hole (33,62), with the idler gear mounting (31,58) being releasably connected to a cylinder block (11).

Abstract: A glow plug assembly having a shield integrally connected to a housing is disposed in and retained in a bore in a cylinder head by a clamp connected to the cylinder head. A stop surface connected to said housing is engageable with the cylinder head and establishes the location of a heating element second end in the combustion chamber. The clamp maintains the stop against the head and the orientation of the shield angled second end relative to the combustion chamber. The heating element is connected to the housing by a spacer and the housing is sealed with a filler material which blocks the transfer of fluid through the housing. The filler material maintains the housing from passing fluid between the first and second housing ends, minimizes the vibration of the electrical conductors and conducts the heat out of the glow plug.

Abstract: A system for automatically controlling lubricating fluid flow in an internal combustion engine having an engine bearing lubricating system, an intake oiling system and a pair of lubricating fluid reservoirs for carrying separate lubricating fluid for delivery to the engine bearing and intake oiling systems is provided. In response to the fluid level in one of the reservoirs being delivered to the intake oil system being at a predetermined low level, the controller swaps reservoirs and delivers fluid flow from the other reservoir to the intake oiling system. The controller commands filling of the low level reservoir prior to delivery of lubricating fluid from this reservoir to the engine bearing lubricating system. The system eliminates the need for lubricating fluid changes.

Abstract: This invention relates to a cooling system for a turbocharger engine having a first and a second fluid passing cooling circuits connected to a common radiator at spaced apart locations on the radiator. The first fluid passing cooling circuit circulates cooling fluid flow between the radiator and the engine and the second fluid passing cooling circuit circulates cooling fluid between an aftercooler and the engine. A temperature controlled valve in the first fluid passing circuit increases the cooling capacity of the second fluid passing circuit when closed or partially closed.

A processor determines the first and second current coordinate positions of the first and second receiving devices in a site coordinate system based on position signals from the first and second receiving devices.
