摘要： An opposed-piston engine with a single crankshaft has a rocker-type linkage coupling the crankshaft to the pistons that utilizes a rotatable pivot rocker arm with full-contact plain bearings. A rocker-type linkage utilizes a rotatable pivot bearing with an eccentric aspect to vary translation of piston linkage along the axial direction of a cylinder, which shifts the top dead center (TDC) and bottom dead center (BDC) locations of a piston so as to change the volume of charge air compressed during the power stroke.

摘要： The invention provides a 2-stroke internal combustion engine comprising two opposed cylinders, each cylinder housing two opposed pistons and having at least one exhaust port and at least one intake port, and a crankshaft having asymmetrically arranged journals and scotch-yoke mechanisms for driving the journals from the pistons. The pistons in each cylinder operate to open its exhaust port or ports before its intake port or ports and to close its exhaust port or ports before its intake port or ports.

摘要： A piston mechanism comprises a crankcase, a crankshaft with three crankpins, a cylinder with diverging pistons defining working chambers having inlet and outlet openings, and two connecting members, one of which cooperates with the middle crankpin and the other with the two outer crankpins. In the body of the cylinder there are guide channels provided, in which connecting rods are arranged in alternating sequence, which are attached to one or the other connecting member by their bases, forming two synchronous groups of connecting rods. The guide channels are provided with through-cuts in the working surface of the cylinder with outlets into its cavity so that the faces of the connecting rods of the synchronous groups facing the cavity of the cylinder form movable parts of its working surface. The pistons are attached by their peripheries to the lateral faces of the connecting rods of one or the other synchronous group sequentially and spaced from each other, forming two movable rigid carcasses inserted in one another, moving in opposite directions.

摘要： Novel internal combustion engines of the swing beam type incorporate an improved construction utilizing a Rapson-slide motion and also are derived from two degree-of-freedom mechanisms for controlling the displacement of the piston as a function of crankshaft displacement and of the displacement of a control shaft. The control shaft either operates at an average speed which is preferably a prescribed ratio of crank speed, thereby yielding an improved thermodynamic cycle (such as the Atkinson cycle in the case of a four-stroke engine) and cycle timing, or functions as a lever for obtaining variable stroke operation. The mechanism can also incorporate a variable compression ratio feature.

摘要： A compression ignition engine has two opposed pistons acting in each cylinder. The pistons are connected to a crankshaft via a rocker beam, and the fulcrum of the rocker beam is at one of its ends so that when the piston is at inner dead center, the little end of the crankshaft/rocker beam connecting rod is at its closest position to the crankshaft axis. The position of the fulcrum is also adjustable, while the pistons are in motion, to alter the engine's compression ratio.
