There is presented various embodiments disclosed in this application, including an improved crankshaft system using a load connecting member which provides a greater maximum torque angle than a conventional system, thereby improving efficiency and power.

A cylinder assembly includes a cylinder with an inlet channel of compressed air and an outlet channel of exhaust gas located in the middle which is closed by a head and a partition. One end of a push rod goes through a linear slide bearing located in the partition. A working piston is rigidly embedded on the push rod. Bottom and top compensating pistons are separated from the working piston by spiral compensating springs. A counter-rotating combustion engine including a crank mechanism is connected to two oppositely directed identical cylinder assemblies via an engine case. The crank mechanism constitutes a crankshaft having two crank half shafts lying opposite each other and connected rotationally. The crank mechanism includes two pairs of connecting rods whose ends are rotationally connected to one of crank half shafts via a rotary shaft. The other ends of the connecting rods are connected to one of two shafts, each connected to a push rod of a cylinder assembly.

Various exemplary embodiments relate to an engine including a cylindrical cassette that converts linear into rotational motion. The linear motion is provided by a normal cylinder and valve mechanism driving pistons in a reciprocating motion, and the rotational motion is transmitted to an output shaft. Further embodiments relate to methods of converting linear motion to rotational motion by using a cylindrical cassette.

An internal combustion engine comprising a crankshaft rotatable about an axis, one or more pairs of cylinders opposed from each other on either side of the crankshaft, one or more pairs of pistons alternately moveable within the cylinders by combustion therein, and a common rod connecting the pair of pistons, the pistons and common rod being linearly slideable in a first direction. A linear bearing is disposed on the common rod between the pair of pistons and connects the common rod to the crankshaft, the linear bearing being slideable in a second direction normal to the first direction. As the pair of pistons alternately move within the cylinders, the crankshaft is driven by movement of the common rod and pair of pistons back and forth in the first direction and movement of the linear bearing back and forth in the second direction.
