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.

An internal combustion engine includes a crankcase that defines a crank chamber, a crankshaft that has a crank housed in the crank chamber and is rotatably supported on the crankcase, a cylinder block that is joined to the crankcase and defines a plurality of cylinders in a horizontally-opposed arrangement, a to-be-detected body that rotates integrally with the crankshaft, and a detection sensor that extends through the crankcase from an upper face of the crankcase, is made to face a trajectory of the to-be-detected body, and generates a pulse signal in response to movement of the to-be-detected body. Thus, in a so-called horizontally-opposed internal combustion engine, a structure for disposing a detection sensor that can detect the angular velocity of a crankshaft with high precision is provided.

Systems, apparatuses and methods in interoperating with multiple clean energy sources, such as pneumatic energy, electrical energy, hydrogen energy and steam energy, with engine configurations employing theses clean energy sources dynamically and synchronously. Further embodiments including fossil fuel energies.

The present invention is directed to a dual engine-compressor system having a crankcase enclosing a crankshaft and having engine cylinder housings and compressor cylinder housings linearly disposed on opposite sides of the crankcase. Combustion pistons are reciprocatingly disposed in the engine cylinder housings and defines alternating combustion chambers on opposite sides of the pistons. Compressor pistons are reciprocatingly disposed in the compressor housings and define alternating low and high pressure compressor chambers on opposite sides of the compressor pistons. The compressor pistons undergo a 4-cycle process to drawn in, re-distribute, and then compress fluid. The compressor cylinder and piston has a series of one-way intakes and reed valves to selectively draw or push fluid in response to movement of the compressor piston.

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.
