    Abstract: An opposed-piston engine assembly is disclosed including a first cylinder liner containing a pair of first pistons that move toward one another in one mode of operation and away from one another in another mode of operation. The pistons are coupled to first and second crankshafts. Multiple block segments arranged in a side-by-side abutting relationship form the engine block including a first outboard segment, a first inboard segment, a second inboard segment, and a second outboard segment. Tensile members extend through the block segments tying them together as one structural unit. The first and second inboard segments abut one another at a seam and include bores that cooperate to receive the first cylinder liner. The first cylinder liner includes a liner support collar that is received in counter-bores defined by the first and second inboard segments at the seam between the first and second inboard segments.

    Abstract: An oil cooled cylinder liner, a method for cooling the same, and an opposed piston engine using the oil cooled cylinder liner are described. The cylinder liner includes a liner wall that has an inner face adjacent a piston bore and an outer face including an oil gallery surface. A plurality of grooves are disposed along the oil gallery surface. The grooves run parallel to each other and are spaced apart by bridging portions of the liner wall. At least some of the grooves have at least one fin disposed therein that runs parallel with the grooves. The grooves in combination with the fins increase surface area of the oil gallery to improve heat transfer from the liner wall to oil disposed along the oil gallery surface.

    Abstract: An opposed-piston, two-stroke engine is provided and includes a first cylinder having a first longitudinal axis and a first pair of pistons slidably disposed within the first cylinder and movable toward one another in a first mode of operation and away from one another in a second mode of operation. The engine additionally includes a second cylinder having a second longitudinal axis and a second pair of pistons slidably disposed within the second cylinder and movable toward one another in the first mode of operation and away from one another in the second mode of operation. A crankshaft is connected to at least one of the first pair of pistons and at least one of the second pair of pistons and has an axis of rotation. The axis of rotation is disposed between and is substantially perpendicular to the first longitudinal axis and the second longitudinal axis.

    Abstract: A clutch assembly that is less prone to overheating is disclosed. The clutch assembly includes a clutch housing, a shaft, and a clutch pack. The clutch pack includes a first apply plate, a second apply plate, a plurality of friction plates, and a plurality of reaction plates. The clutch assembly further includes a first actuator and a second actuator. The first actuator applies pressure to the first apply plate in a first direction to move the first apply plate toward the second apply plate. The second actuator applies pressure to the second apply plate in a second direction to move the second apply plate toward the first apply plate. The first direction is opposite the second direction such that the first and second actuators apply pressure to the clutch pack in opposing directions. This reduces localized temperature spikes in the clutch pack.

    Abstract: A fuel injector includes a nozzle, a needle, and a pressure control section. The nozzle has first and second ends and extends along a first longitudinal axis from the first end to the second end. The nozzle includes a nozzle body defining a first longitudinal passage that extends along the first longitudinal axis and through the second end of the nozzle. The needle is disposed within the first longitudinal passage and is movable between a first position in which the needle prevents fuel from flowing through the second end of the nozzle and a second position in which the needle allows fuel to flow through the second end. The pressure control section extends along a second longitudinal axis that is angularly offset relative to the first longitudinal axis of the nozzle. The pressure control section includes an electromechanical actuator that actuates the needle between the first and second positions.
