An improvement to a rotor is provided adapted to be rotated by at least two linearly moving support bearings linearly driven by an engine that comprises an outer ring provided on a circumference of the rotor; and an inner ring that is concentric to the outer ring. The support bearings are confined to rotate within a restraining path formed between the outer ring and the inner ring. It is also provided an improved engine having at least two traverses linearly actuated that comprises the improvement.

Apparatus and associated methods relate to nutating a piston drive linkage oriented around a longitudinal axis in response to the rotation of a drive shaft about a drive axis, said longitudinal axis being offset and canted with respect to said drive axis. In an illustrative example, the piston drive linkage may be formed as a wobble plate extending radially from the longitudinal axis. Near a periphery, the wobble plate may attach to a plurality of stationary piston cranks. The nutating motion of the piston drive linkage may impart a substantially linear motion profile substantially parallel to the drive axis of rotation. A bearing oriented around the longitudinal axis may advantageously be freely inserted into and removed from an aperture in the wobble plate. An inner race of the bearing may freely rotate about the longitudinal axis in response to rotation about the drive axis.

An optical measurement device is disclosed and includes a body configured to be mounted to at least one piston cylinder, and a compression ratio determination unit operatively connected to the body to receive optical measurement data and compute a clearance between at least two opposed pistons disposed within the at least one piston cylinder.

A two cycle-opposed piston, two cycle, homogenous charge compression ignition engine with cylinder sets, each cylinder set having a first cylinder with an intake port; a second cylinder coaxially aligned with the first cylinder and having an exhaust port; a first piston engaged within the first cylinder; a second piston engaged within the second cylinder; a combustion chamber formed between the first piston and the second piston; a first cam mechanically engaged with the first piston; a mechanical device to convert reciprocating motion to rotational motion connected to the second piston; and a charge pump connected to the intake port by an intake passage.

The invention relates to a machine that amplifies the drive torque of a moving shaft, which is formed by at least one pair of identical units facing a central shaft, each unit being formed by at least one mechanical actuator (cam), a hydraulic actuator (amplified linear force that provides the application of Pascal's law) and a mechanism comprising a piston, connecting rod and crankshaft. For mechanical considerations, the machine is a two-stroke engine (compression and intake) having at least two opposite horizontal pistons, that is, a 180 V engine.
