摘要： A cylinder head assembly includes a cylinder head casting, and an injector sleeve within an injector bore in the cylinder head casting. The injector sleeve includes a first sleeve end, and an injector clamping surface formed by an inner sleeve surface adjacent to a cylindrical second sleeve end. The injector sleeve further includes a sleeve clamping surface in contact with an upward facing middle deck surface of the cylinder head casting, and a reaction wall extending between the injector clamping surface and the sleeve clamping surface to transfer an injector clamping load to the upward facing middle deck surface.

摘要： 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.

摘要： An engine power module includes a water jacket, a cylinder liner, and a cylinder head. The water jacket forms a coolant supply conduit arranged in a lower coolant annulus extending around the cylinder liner and an upper coolant annulus extending around the cylinder head. The cylinder head has formed therein an injector bore, and a plurality of drill holes convergent on the injector bore. A lower coolant cavity in the cylinder head forms a coolant flow path extending circumferentially around the injector bore between a cavity inlet opening fluidly connected to the coolant supply conduit, and a cavity connection opening fluidly connected to an upper coolant cavity. The arrangement provides flows of coolant through the drill holes to cool an injector sleeve, and separate coolant flows through the lower coolant cavity and upper coolant cavity.
