Abstract: An opposed-piston, two-stroke engine is provided and includes a first cylinder having a first longitudinal axis, a first inlet port, and a first exhaust port. First pistons are slidably disposed within the first cylinder and are movable toward one another and away from one another. The engine additionally includes a second cylinder having a second longitudinal axis, a second inlet port, and a second exhaust port. The second cylinder is disposed adjacent to the first cylinder with the second inlet port being aligned with the first exhaust port in a first direction extending substantially perpendicular to the first longitudinal axis and the second longitudinal axis, and the second exhaust port being aligned with the first inlet port in the first direction. Second pistons are slidably disposed within the second cylinder and are movable toward one and away from one another.

Abstract: A cooling system for an internal combustion engine according to the principles of the present disclosure includes an engine block, a compression device, a cooling circuit, a first pump, and a fuel delivery device. The engine block at least partially defines a combustion chamber and a cooling passage. The cooling passage extends through the engine block. The compression device is received in the engine block to partially define the combustion chamber. The compression device is movable within and relative to the engine block. The cooling circuit is in fluid communication with the cooling passage. The first pump is in fluid communication with the cooling circuit and is configured to circulate a fuel through the cooling circuit and the cooling passage. The fuel delivery device is in fluid communication with the cooling circuit and is configured to deliver the fuel to the combustion chamber.

Abstract: A powertrain system is provided and may include a combustion engine, a crankshaft, and a turbo-compounding system. The combustion engine may include an intake manifold and an exhaust manifold. The crankshaft may be driven by the engine. The turbo-compounding system may be configured to drive the crankshaft and may include a first turbine and a drive system. The first turbine may include an inlet fluidly communicating with the exhaust manifold. The drive system may include an input shaft driven by the first turbine, and an output shaft engaged with the crankshaft. The drive system may be configured to drive the output shaft at more than one drive ratio relative to the input shaft.

Abstract: An engine assembly including a cylinder wall extending about a cylinder bore is disclosed. A piston slidingly received within the cylinder bore includes a ring groove extending about the piston in a ring plane that is transverse to a longitudinal axis of the cylinder bore. A piston ring is received in the ring groove of the piston. A port extends through the cylinder wall to communicate fluid to or from the cylinder bore. The port has an oblique geometry relative to the ring plane and a plurality of windows that extend at least partially about the cylinder bore in a path that is transverse to the ring plane. The oblique geometry of the port staggers entry and exit of the piston ring relative to the plurality of windows as the piston reciprocates within the cylinder bore. This helps prevent the piston ring from clipping the port.

Abstract translation: 公开了一种包括围绕气缸孔延伸的气缸壁的发动机组件。 滑动地容纳在所述气缸孔内的活塞包括环形槽，所述环槽围绕所述活塞在与所述气缸孔的纵向轴线横向的环平面中延伸。 活塞环容纳在活塞的环槽中。 端口延伸穿过气缸壁，以将流体与气缸孔连通。 该端口具有相对于环平面的倾斜几何形状，以及在横向于环平面的路径中至少部分地围绕气缸孔延伸的多个窗口。 当活塞在气缸孔内往复运动时，端口的倾斜几何形状在活塞环相对于多个窗口停止进入和离开。 这有助于防止活塞环夹住端口。
