Abstract: A turbo-compounding system may include a first turbine, a turbocharger, a bypass passageway and a valve. The first turbine may include an inlet in fluid communication with an exhaust manifold and an outlet in fluid communication with a fluid passageway. The first turbine may be drivingly coupled to an engine. The turbocharger includes a first compressor and a second turbine. The first compressor receives an intake fluid at a first pressure and discharges the intake fluid at a second pressure. The second turbine may drive the first compressor and receive exhaust gas from the fluid passageway downstream of the outlet of the first turbine. The bypass passageway may include a first end fluidly coupled with the engine exhaust manifold and a second end fluidly coupled with the fluid passageway downstream from the first turbine and upstream of the second turbine. The valve controls fluid-flow through the bypass passageway.

Abstract: A piston may include an outer peripheral surface and a crown. The outer peripheral surface may include first and second openings spaced about and extending through the outer peripheral surface. The crown may include a recess at least partially defined by a first lobe in fluid communication with the first opening and a second lobe in fluid communication with the second opening. Each of the first and second lobes may be recessed relative to an adjacent portion of the recess of the crown.

Abstract: In one configuration, the present disclosure provides a cylinder including a first housing, a second housing, and an insert. The first housing includes a first body portion and a first collar portion. The first body portion has a first inner diameter, and the first collar portion has a second inner diameter that is greater than the first inner diameter. The second housing includes a second body portion and a second collar portion. The second body portion has a third inner diameter and the second collar portion has a fourth inner diameter that is greater than the third inner diameter. The second housing is coupled to the first housing such that the first and second collared portions cooperate to form an annular channel. The insert is disposed within the annular channel formed by the first and second collared portions.

Abstract: An opposed piston engine may include a first housing, first and second pistons, and first, second, and third fuel injector nozzles. The first housing may define a first passage extending along a first longitudinal axis. The first and second pistons may be slidably disposed within the first passage. The first, second, and third fuel injector nozzles may be in fluid communication with the first passage. At least one of the first, second, and third fuel injector nozzles may be angularly offset from another one of the first, second, and third fuel injector nozzles by an oblique angle about the first longitudinal axis.

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 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: An engine control system includes first and second control modules. The first control module determines a fuel combustion parameter. The second control module determines a fuel delivery parameter based on the fuel combustion parameter. The fuel combustion parameter includes at least one of (i) a total amount of heat released by a volume of fuel during a combustion cycle and (ii) a rate at which heat is released during the combustion cycle. The fuel delivery parameter includes at least one of (i) a duration of time over which the volume of fuel is delivered to a cylinder, (ii) a time at which a fuel injector starts delivering the volume of fuel to the cylinder, and (iii) a fuel pressure in a fuel rail.
