Abstract: A configuration for a uniflow-scavenged, opposed-piston engine reduces exhaust cross-talk caused by mass flow between cylinders resulting from one cylinder having an open exhaust port during scavenging and/or charging while an adjacent cylinder is undergoing blowdown. Some configurations include a wall or other barrier feature between cylinders that are adjacent to each other and fire one after the other. Additionally, or alternatively, some engine configurations include cylinders with intake and exhaust ports sized so that there is an overlap in crank angle of two or more cylinders having open exhaust ports of about 65 crank angle degrees or less.

Abstract: The invention provides an internal combustion engine comprising a piston mounted for reciprocating linear motion within a cylinder along a cylinder axis. The piston is coupled to an output shaft by a power transfer assembly arranged to convert linear motion of the piston to rotary motion of the output shaft. The piston has a first head moveable within a first chamber and a second head opposite the first head and moveable within a second chamber. The power transfer assembly has a lubrication system for lubricating moving components of the power transfer assembly. The lubrication system is sealed from the first chamber and the second chamber to prevent the passage of fluid from the lubrication system into the first chamber and the second chamber.

Abstract: Control of airflow in a uniflow-scavenged, two-stroke cycle, opposed-piston engine during transient operation includes monitoring at least one operating parameter of the engine to recognize a transition to a transient state of engine operation. If a transient state of operation is detected, fuel injection and airflow into to the cylinders of the engine are controlled to optimize combustion and limit emissions. Airflow into cylinders of the engine may be controlled by increasing a scavenging ratio of the engine or by increasing a trapping efficiency of the engine.

Abstract: An opposed-piston engine includes a ported cylinder and a pair of pistons disposed to reciprocate in the bore of the cylinder. A combustion chamber is defined by opposing shaped piston end surfaces as the pistons approach respective top dead center (TDC) locations in the bore. At the end of scavenging, the shaped end surfaces of the pistons interact with swirl to produce turbulence in the charge air motion in the combustion chamber; the additional bulk motions include tumble. Fuel is injected into the turbulent charge air motion along a major axis, of the combustion chamber.

Abstract: In an air handling system of a uniflow-scavenged, two-stroke cycle opposed-piston engine, one or more engine operating state parameters are sensed, numerical values of air handling parameters based on trapped conditions in a cylinder of the engine at the last port closing of an engine operating cycle are determined in response to the sensed parameters, the numerical values are evaluated, and one or more of the numerical values is adjusted in response to the evaluation. The adjusted numerical values are used to control charge air flow and EGR flow in the air handling system.

Abstract: An internal combustion engine enabling asymmetric port timing has an engine mechanism including a crankshaft having a crankpin to which each piston of an opposed pair of pistons is connected and by which the pistons are reciprocatable in a respective one of axially inline cylinders. The mechanism also includes a crosshead having opposite ends on each of which a respective piston is mounted, and a coupling between the crosshead and the crankpin by which the pistons are caused to oscillate circumferentially as the pistons are driven to reciprocate.

Abstract: A port for a cylinder of a two-stroke cycle engine includes at least one generally circumferential array of port openings. Port openings have a shape that reduces ring clipping during engine operation. The port opening shape is defined at a bore surface by opposing top and bottom edges joined by side edges. Each of the top and bottom edges is characterized by rounded corner transitions to the side edges, a rounded peak, and inclined ramp portions extending from the rounded corner transitions to the rounded peak.

Abstract: The present disclosure is directed toward implementations of internal combustion engines. The disclosure describes various embodiments of internal combustion engines where most of the internal elements rotate. Such engines allow for more efficient transfer of the energy created by combustion to the motive components of a vehicle such as wheels or propellers. One specific embodiment includes a rotating cylinder with a single piston which both reciprocates and rotates. The rotating motion of the piston is transferred to the cylinder, which in turn is connected to a driveshaft. Various embodiments of the invention employ differing numbers and configurations of pistons. All embodiments have the advantage of decreasing engine volume and increasing efficiency over traditional internal combustion engines.
