A modular internal combustion engine (10) comprising a cam crank (74) having a piston stroke guide pattern (76) to control the stroke motion profile of the piston (70), which can be expanded by replacing the crank shaft (22) with a longer crank shaft (22), and installing a supplemental engine block (18) with a supplemental cam crank assembly (75).

An opposed piston engine includes a cylinder having a cylinder wall, and a pair of opposed pistons, Each face of each piston of the pair of opposed pistons has a top plane and a recess formed therein, each recess comprising a first surface defining part of a cone, the cone defined by the first surface of at least one of the recesses having a longitudinal axis that defines an angle equal to at least one half of a cone angle of the cone with the top plane.

The system comprises an opposed piston engine. The pistons (1) consist of a top piston half (1a), a spring (1b) and a bottom piston half (1c). The cylinders (3) have inlet channels (8) for compressed air as well as outlet channels (10). fuel injector (12), steam injector (13) and ignition clement (14). A bipartite crankshaft (15) is fitted with exit shafts (19a, 19b) connected with impellers (22) via clutches (20a, 20b). Rotor rims (26) around the impellers contain magnetic dipoles (28), whereas stator rims (27) have induction coils (29). One method concerns using of resilience of a spring situated between two halves of the piston, furthermore piston halves are cooled by a spurt of compressed air. Another method concerns transferring some part of energy of the impeller to the system of collecting and transferring energy attached to it, from which energy is taken in case of an insufficient torque on the impeller shaft.

The present invention relates to internal combustion engines, and discloses a double-cylinder internal combustion engine. The double-cylinder internal combustion engine of the present invention adopts a curved groove ball bearing mechanism to replace crank-connecting rod mechanisms since traditional internal combustion engines have a complicated structure, high material requirements, high processing difficulty, and the inertia effect and noises thereof are hard to be eliminated. Two inner rings of the curved groove ball bearing mechanism are fixedly connected, and a valve mechanism and an ignition mechanism are driven through a gear pair, so that the two sets of cylinders and pistons reciprocate in opposite directions to automatically balance reciprocating inertia thereof. Compared with the prior art, the present invention has simple motion forms which only consist of the rotary motion and the reciprocating motion, and low noises are produced. The inertia of the reciprocating motion is automatically offset, causing small vibrations.
