This patent discloses thrust vectoring ignition chamber engine. Thrust vectoring ignition chamber used in this engine is an annular cylinder having nozzles mounted in a way such that during fuel suction phase they are sealed and during ignition of fuel they are unsealed so that hot jets of ignited fuel escaping through nozzles cause coupled rotatory motion on the ignition chamber. Engine uses cam operated specially designed bilaterally operated double action scotch-yoke mechanism which facilitates two phase suction and compression of fuel and facilitates separation of fuel valve from ignition chamber. Flywheel mounted on extension of ignition chamber functions as output of the engine. Each half rotation of flywheel completes three phases namely fuel/air suction, compression and combustion. Thus this engine fires for every half revolution and therefore can give improved power boost.

It is disclosed a boxer engine with two substantially mirror-symmetric engine sides (L, R) comprising a crankshaft (1) to which is connected, at least two main scotch yoke assemblies (110) each having one main piston (7) arranged inside one main cylinder (I, III; II, IV) of each engine side (R; L), and at least one auxiliary scotch yoke assembly (120) having a pair of auxiliary pistons (8) arranged inside a pair of auxiliary cylinders (V, VII; VI, VIII) of each engine side (R; L), wherein the main scotch yoke assemblies (110) are arranged synchronized on the crankshaft (1) and the at least one auxiliary scotch yoke assembly (120) is arranged 180° offset on the crankshaft (1), each auxiliary piston (7) defining an outer space and an inner space within each auxiliary cylinder (V, VII; VI, VIII), the inner space facing the opposite engine side (R; L), wherein, said inner spaces of each auxiliary cylinder (V, VII; VI, VIII) pair are in fluid communication and forming a compression chamber, said compression chamber comprises first and second check valves (69, 70), wherein the auxiliary cylinder (V, VII; VI, VIII) pair is adapted to suck in ambient air through the first check valve (69) and compress and pump said air out through the second check valve (70) into a main cylinder (I, III; II, IV) of the opposite engine side (R; L), and said outer spaces of each auxiliary cylinder (V, VII; VI, VIII) pair are in fluid communication and are receiving pressurized exhaust gas from a main cylinder (I, III; II, IV) of the same engine side (R; L).

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.

An internal combustion engine including at least two cylinders with parallel longitudinal axes, each cylinder including an opening and a piston capable of moving in translation inside the cylinder, the respective openings of the cylinders facing each other, the pistons being in kinematic relation with a connecting rod-crank mechanism including: a spacer connecting the pistons, suitable for maintaining a fixed spacing between the pistons, the pistons being respectively attached to the arms of the spacer, a crankshaft rotating about an axis, arranged between the openings of the cylinders and between the longitudinal axes of the cylinders, the crankshaft comprising a crank pin, a rocker rotating about the crank pin, at least one connecting rod including a first, small end, rigidly attached to the spacer and a second, big end, rigidly attached to one of the ends of the rocker.

The present invention is directed to a process for operating a combustion engine having a double-sided piston in a piston cylinder, wherein every stroke of the double-sided piston is a power stroke. Every piston cylinder defines a combustion chamber on each side of the double-sided piston. The process includes igniting a fuel-air mixture in each combustion chamber on each side of double-sided piston during every compression, i.e., at about top dead center and at about bottom dead center. The process utilizes the double-sided piston to achieve two power strokes per piston for each engine cycle.

A double-piston compressor of a compressed air supply device includes a first pressure stage and a second pressure stage, each having a cylinder with a piston guided therein in an axially movable manner. The piston of the cylinder of the first pressure stage and the cylinder of the second pressure stage are rigidly connected to one another via a piston rod and are in driving connection with the drive shaft via a slotted guide. The slotted guide comprises a recess which is formed in the piston rod, provided with a slotted guide track and oriented perpendicularly to an axis of rotation of the drive shaft with its cross-sectional plane. The slotted guide comprises a drive roller which is engaged with the recess and fastened to the drive shaft in an axially parallel, eccentric, and also rotatable manner with respect to the axis of rotation of the drive shaft.
