An internal combustion engine includes a housing defining an internal cavity, an inner body sealingly moving within the internal cavity for defining at least one combustion chamber of variable volume, a pilot subchamber in communication with the at least one working chamber, an ignition element in communication with the pilot subchamber, a main injector communicating with the at least one combustion chamber, and a pilot injector having a tip in communication with the pilot subchamber. The tip of the pilot injector includes at least a first injection hole defining a first spray direction and a second injection hole defining a second spray direction different from the first spray direction. The first spray direction extends toward the communication between the pilot subchamber and the at least one working chamber. A method of performing combustion in an internal combustion engine is also discussed.

A rotary engine, parts thereof, and methods associated therewith is provided. The engine is modular and adjustable to accommodate a variety of requirements and preferences. The system includes a combustion assembly having a housing and a power rotor positioned therein. The power rotor rotates in a first direction from the beginning of each combustion process through the end of each exhaust process. The system also includes a compression assembly linked to the combustion assembly such that the compression rotor rotates in the first direction from the beginning of each intake process through the end of each compression process. A tank assembly in fluid communication with the compression assembly and the combustion assembly provides stability to the system while eliminating or otherwise reducing transitional loses.

An internal combustion engine has a plurality of engine units, each having a working space, in which two rotary pistons are arranged so as mesh with each other and thereby divide the working space into an inflow region and an outflow region. Each engine unit has a closable inlet opening to the inflow region and a closable exhaust gas outlet opening. The internal combustion engine further includes a feed-line pipe to the inlet openings and an exhaust gas collection pipe connected to the exhaust gas outlet openings, so that the engine units are connected in parallel with each other. The internal combustion engine further includes exhaust gas lines which connect the engine units with each other in series. In certain cases, a control device operates some of the engine units either as internal combustion engines, or as expansion engines.

Rotary internal combustion engine includes a body made of four parts, each of which is an L-shaped fragment, and, when connected, forming two mutually perpendicular ring-shaped walls in plan view with ribs on the outer surface and an annular groove inside, which form two passages, each of which contain a torus-shaped rotor, which can move along the groove. Each torus-shaped rotor has longitudinal notches located outside or inside the rotor forming cavities between the rotor and groove surface, connected to chambers located outside the walls. The intake and exhaust windows are made in the walls communicating with the cavities between the rotor and groove surface. The rotors are interconnected by the kinematic chain of rotation synchronization made of successively engaged gears, one of which is engaged with one torus-shaped rotor, and the last of the gears is engaged with the output shaft, rigidly connected with another torus-shaped rotor.

An apparatus and a method comprises a housing comprising at least a recessed area and an inner wall. A plurality of plates are disposed within the housing and configured to form a structure. The structure has an outside surface. The structure is capable of being articulated between a first configuration and a second configuration and a third configuration.
