  • Patent number: 11686295
    Abstract: A variable stroke high pressure pump is disclosed. The pump uses a wobble plate design with dynamically variable tilt to provide continuous adjustment of pump stroke length and output. Dynamically variable tilt is accomplished using a linearly actuated tilt thruster rotationally coupled to the drive shaft to maintain a selected tilt of the wobble plate through the rotation of the wobble plate.

  • Patent number: 10718262
    Abstract: A continuously variable displacement engine has a plurality of pistons received in a cylinder block and connected to a nutator. A crankshaft with an axis of rotation is carried in a crankcase and incorporates an upper journal with a first angle relative to the axis and a lower journal with a second angle with respect to the axis. A first slider ball is engaged on the upper journal and a second slider ball engaged on the lower journal. A carrier assembly captures the first and second slider balls and incorporates an actuating cylinder. An actuation piston assembly is translatably carried in the actuating cylinder and connected to the crankshaft intermediate the upper journal and lower journal. The actuating piston is controllably translated between a first high eccentricity position and second low eccentricity position. An anti-rotational assembly connects the nutator to a piston case.

  • Patent number: 10041405
    Abstract: A variable-displacement engine comprises an engine block, cylinders and power shaft. Pistons and connecting rods mounted in the cylinders drive a wobble plate having a rotating ring portion and non-rotating ring portion connected to allow relative rotation therebetween while constraining the portions to remain parallel. The wobble plate defines an inclination plane, pivot axis and wobble plate angle ?. A piston control mechanism (PCM) includes a control yoke rotating with the power shaft and extending to an axially and radially fixed anchor line, a control shaft mounted on the yoke at the control line and a control arm extending from the rotating ring portion and defining a control slot captured over the control shaft. A lift mechanism changes the axial position of the pivot axis, in turn changing, via the PCM, the wobble plate angle ?. This changes the piston displacement of the engine while maintaining a predetermined compression ratio.

The wobble plate defines an inclination plane, pivot axis and wobble plate angle ?. A piston control mechanism includes axial lift, control lever supported by the lift and by an anchor bearing, and links connecting the control lever to the wobble plate. Axial movement of the lift changes the axial position of the control lever pivot and changes the control lever angle, in turn changing, via the connecting links, the wobble plate angle ? and the axial position of the wobble plate pivot axis. This changes the piston displacement of the engine while maintaining substantially constant compression ratio.

  • Patent number: 8833339
    Abstract: The disclosure relates to reciprocating piston engines having four cylinders with a circular cross section, cylinder axes which are parallel to one another, and an output shaft. The cylinder axes, as viewed in axial section, lie at the corner points of a rectangle that is a square, with the output shaft, which extends parallel to the cylinder axes, in the center of the square. Each pair of cylinders which lie diagonally opposite one another are arranged in the same direction, as viewed axially, and in opposite directions, as viewed axially, with respect to the other pair of cylinders. The force or moment from each cylinder is transmitted to the output shaft via a dedicated rotating crank and a toothing system.

  • Patent number: 8464671
    Abstract: The horizontally opposed center fired engine improves on the traditional design of the horizontally opposed engines and center fired engines with a better engine geometry. The present invention utilizes four pairs of opposing pistons to compress a larger volume of air-fuel mixture within four different cylinders. The four different cylinders are radially positioned around a center axle in order to achieve a perfectly symmetric engine geometry. The center axle consists of two different shafts spinning in two different directions, which could drastically reduce engine vibrations in the present invention. Engine vibrations are caused by a change in engine speed and result in a loss of energy. Due to the design, the present invention will only experience energy loss in the form of entropy and friction. Thus, the present invention can convert a higher percentage of chemical energy into mechanical energy than any other internal combustion engine.

  • Patent number: 7377238
    Abstract: A variable compression ratio device of an internal combustion engine includes a piston inner part connected to a connecting rod and a piston outer part fitted on an outer periphery of the piston inner part. The piston outer part is only slidably in an axial direction, and is movable between a low compression ratio position near the piston inner part and a high compression ratio position near the combustion chamber. A skirt part is slidable and is guided by an inner peripheral surface of a cylinder bore of an engine. The skirt part is integrally formed on the piston inner part. A peripheral wall of the piston outer part is terminated directly above the skirt part. Thus, switching of the position between the low compression ratio position and the high compression ratio position by an inertia force of the piston outer part is performed smoothly with a reduction in weight of the piston.

  • Patent number: 6938589
    Abstract: An internal combustion engine having at least one piston with an adjustable stroke length. The engine includes a connecting rod attached to the piston and a crankshaft. The crankshaft has a journal portion that extends along a length that is non-perpendicular to a movement axis of the piston. The crankshaft may be moved in a longitudinal direction with respect to the piston to adjust the position of the connecting rod on the journal portion and to thereby adjust the stroke length of the piston.
