Abstract: A compressor housing for a turbocharger may include an outer volute having an outer volute inner surface with a clamp groove defined therein, and an inner volute having an inner volute outer surface and an axially facing surface. The inner volute is inserted into the outer volute through the outer volute inner surface with the inner volute outer surface facing the outer volute inner surface. The inner volute is positioned with the axially facing surface disposed axially inward of the clamp groove. A clamp plate includes a radially outward portion inserted into the clamp groove and a radially inward portion extending downward past the inner volute outer surface. The clamp groove and the axially facing surface engage the clamp plate to retain the inner volute within the outer volute when an axial load is applied to the inner volute.

Abstract: A method of bank to bank trimming for a locomotive engine during steady state operation comprises receiving a plurality of operating parameter signals, receiving a fuel quantity signal for each of a standard cylinder bank and a donor cylinder bank, providing a trim map, determining whether the engine is operating in a steady state condition based on the plurality of operating parameter signals, determining a target fuel injection duration for each of the standard cylinder bank and the donor cylinder bank if the engine is operating in a steady state condition, and adjusting an actual fuel injection duration to equal the target fuel injection duration for the standard cylinder bank and the donor cylinder bank.

Abstract: A jacket cooling system for an engine of a locomotive is disclosed. The jacket cooling system may comprise a jacket coolant pump driven by a crankshaft of the engine. The jacket cooling system may further comprise a coolant jacket associated with one or more components of the engine, and a delivery conduit in fluid communication with the outlet of the jacket coolant pump and configured to deliver a coolant from the jacket coolant pump to the coolant jacket. The jacket cooling system may further comprise a bypass circuit configured to divert the coolant away from the delivery conduit and the engine, and an electronically-controlled bypass valve in the bypass circuit. The bypass valve may allow at least some of the coolant to flow through the bypass circuit when a valve position of the bypass valve is at least partially open.

Abstract: The preset disclosure provides a control system for operating one or more locomotives in a train, the control system including a first communication unit located on-board a first locomotive of a first consist in the train; and an off-board remote controller interface located remotely from the train, the off-board remote controller interface being configured to receive or generate a locomotive control command, store the received or generated locomotive control command in a shared ledger, and relay the locomotive control command to the first communication unit. The first communication unit is configured to receive the locomotive control command from the off-board remote controller interface.

Abstract: A turbocharger variable speed control mechanism for a turbocharger for an engine includes a sun gear of a planetary gear set coupled to a turbocharger shaft, a planet carrier operatively connected to an engine output shaft of the engine, a brake disk coupled to and rotatable with a ring gear, and a brake actuator mechanism proximate the brake disk and mounted to a turbocharger housing. The brake actuator mechanism is selectively actuatable between a non-braking state where no braking force is applied to the brake disk so that the ring gear is free to rotate relative to the turbocharger housing, and a full braking state where a full braking force is applied to the brake disk such that the ring gear is held stationary relative to the turbocharger housing and rotation of the planet carrier is transmitted through the planetary gear set to cause rotation of the turbocharger shaft.

Abstract: A fuel tender for providing fuel to an internal combustion engine of a marine vessel may include a first pontoon, a second pontoon, and a truss structure connecting the first pontoon to the second pontoon with the first pontoon being separated from the second pontoon by a pontoon separation distance that is greater than a vessel width of the marine vessel so that the first pontoon and the second pontoon can straddle a vessel stern of the marine vessel with the truss structure disposed above a stern deck of the marine vessel. A fuel reservoir may be mounted on the truss structure and have a fuel supply line extending therefrom, with the fuel supply line being fluidly connectable to a fuel inlet port for the internal combustion engine when the first pontoon and the second pontoon straddle the vessel stern of the marine vessel.

Abstract: A cooling system is disclosed for an internal combustion engine. The cooling system may include a first cooling circuit having a first coolant that flows through cooling channels of an engine, and a second cooling circuit having a second coolant that flows through a charge air cooling component. The cooling system may further include a drain line adapted for fluid communication with the first and second cooling circuits. A first temperature responsive valve disposed on the second cooling circuit may be included, the first temperature responsive valve configured to open to allow mixing of the first and second coolants when the temperature of the second coolant is at a preselected minimum temperature. Also included may be a second temperature responsive valve disposed on the drain line and configured to open to drain both cooling circuits when the temperature of the first and second coolants is at a preselected minimum temperature.

Abstract: A valvetrain for an engine includes a pair of valves that are disposed in a spaced apart relation to one another, and in which each of the valves has an elongated valve stem. The valvetrain further includes a valve bridge that is coupled to the pair of valves. The valve bridge is configured to define a pair of receptacles to at least partly receive the pair of valve stems therein. The valve bridge further defines a central recess that is located midway between the pair of receptacles and disposed in a co-planar relationship with the pair of receptacles.
