    • A concentric cylinder engine includes a toroidal outer cylinder having an inner cylinder contained therein, the inner cylinder wall comprising a sleeve assembly acting as a transfer valve. Each cylinder contains a piston, the two pistons being connected to a single crankshaft. The inner and outer piston crank throws are at least generally opposite one another, with the two pistons traveling in opposite directions during engine operation. The outer piston provides intake and compression functions, while the inner piston simultaneously provides power and exhaust functions. The concentric cylinder engine thus provides the four separate and distinct intake, compression, power, and exhaust phases of conventional Otto cycle engine operation during a single revolution of the crankshaft. The concentric cylinder engine may be constructed in multiple cylinder configurations having spark or compression ignition, in either liquid or air cooled embodiments.

    • An engine includes an engine shaft configured to rotate and cause one or more pistons to reciprocate within a cylinder chamber along an axis, each piston having a first piston part and piston stem to move in unison with or separately from a second piston part to define piston strokes for different thermal functions of the engine. The engine further includes a piston lever having a first end coupled to a movable fulcrum point and a second end coupled at a copy point to the piston stem, an actuation mechanism configured to move the piston lever and thereby the copy point, and a guide apparatus configured to dictate movement of the copy point in a direction substantially parallel to the cylinder axis.

    • An internal combustion engine has a piston reciprocating between a piston top dead center, PTDC, and a piston bottom dead center, PBDC. The piston is slidably arranged in a sleeve which reciprocates between a sleeve top dead center, STDC, and a sleeve bottom dead center, SBDC. The sleeve is slidably arranged in a cylinder. The movements of the piston and the sleeve are synchronized such that when the sleeve is at its SBDC, the piston is at its PBDC, and during a movement of the sleeve from the SBDC to the STDC, the piston performs a reciprocating motion from the PBDC to the PTDC and back to the PBDC. During a movement of the sleeve from the STDC to the SBDC, the piston again performs a reciprocating motion from the PBDC to the PTDC and back to the PBDC, or the piston remains stationary at its PBDC.
    • 内燃机具有在活塞上止点PTDC和活塞下止点PBDC之间往复运动的活塞。 活塞可滑动地布置在套筒中,该套筒在套筒上止点STDC和套筒下止点SBDC之间往复运动。 套筒可滑动地布置在圆筒中。 活塞和套筒的运动是同步的,使得当套筒处于其SBDC时,活塞处于其PBDC,并且在套筒从SBDC移动到STDC期间,活塞执行从PBDC的往复运动 到PTDC并返回到PBDC。 在套筒从STDC移动到SBDC期间,活塞再次执行从PBDC到PTDC的往复运动并返回到PBDC,或活塞在其PBDC处保持静止。

    • An engine is provided with two chambered cylinder bifurcated by a liner with such a ratio of volumes that the annular outer chamber to act as a compression chamber/zone while the suitably designed piston is moving towards Top Dead Center (TDC), and the inner chamber to act as an expansion zone with enough volume such that when the burnt gases are expanded during power stroke, the gases reaches pressure equivalent to atmospheric pressure and thus enabled to extract more power following Atkinson Cycle successfully. In particular, the volume ratio between the compression & expansion is provided by different effective cross sectional areas of compression chamber (encapsulated by the outer portion of cylinder (20), cylinder middle block (14), liner (23) and piston outer part (61) and the expansion chamber (encapsulated by liner (23) cylinder head (13) and piston inner part (60) ) for the same stroke length.
