    摘要： A crank and connecting rod mechanism, comprising at least one piston, which reciprocates within at least one cylinder, comprising: at least one connecting rod, comprising: a piston end pivotally connected to the at least one piston, a crank end; at least one gear set, comprising: a crankpin, the crank end pivotally connected to the crankpin; a crank gear; a crank gear shaft, the crank gear rotatably mounted on the crank gear shaft, the crankpin located between centerline of the crank gear shaft and radius of the pitch circle of the crank gear; a stationary gear, the crank gear meshing with the stationary gear, the crank end driving the crankpin, which drives the crank gear and the crank gear shaft about the stationary gear; the crank pin and the crank end rotating about the stationary gear and following the path of a roulette of a centered trochoid about the stationary gear.

    摘要： An opposed-piston engine with two crankshafts includes a first power transducer coupled to a first crankshaft of the two crankshafts and a second power transducer coupled to a second crankshaft of the two crankshafts. The two crankshafts are not rotatably connected, and so are free to rotate independently of each other. Phase relationships between the crankshafts may be controlled by operating the power transducers to increase, or reduce, crankshaft torque. Changes in crankshaft phase relationships cause changes in opposed piston locations, which, in turn, enable control of engine performance factors.

    摘要： Technology is provided for a bilateral engine control system for use on a multi-cylinder opposed piston engine. The system includes first and second sets of injectors, each set mountable on first and second sides of an engine. Each injector is in fluid communication with a corresponding cylinder of the engine. First and second engine control units are each connected to a respective set of injectors. First and second crankshaft speed sensors are connected to respective engine control units. The first engine control unit independently controls the first set of injectors based on a first speed signal and the second engine control unit independently controls the second set of injectors based on a second speed signal. The first engine control unit and the second engine control unit are configured to activate corresponding injectors of the first and second sets of injectors at substantially the same time.

    摘要： A free piston apparatus includes a piston receptacle in which a piston device having a piston is reciprocable along an axis. The piston receptacle includes or forms a chamber delimited by a wall arrangement forming an inlet opening and an outlet opening. A cooling device is arranged on the piston receptacle for cooling the wall arrangement. The cooling device includes or forms a cooling channel arranged radially outside on the wall arrangement. The cooling channel has first and second cooling regions axially on opposing sides of the outlet opening. The piston receptacle includes or forms an outlet chamber, arranged outside on the wall arrangement, for exhaust gas exiting via the outlet opening. The cooling channel has a third cooling region which flow-connects the first cooling region and the second cooling region along the outlet chamber and is positioned at least in sections radially outside of the outlet chamber.
