摘要： The invention concerns an engine, wherein the piston (6a, 6b) linked by pairs, through a rigid rod (7) form a running part moving in opposed cylinders (2a, 2b) aligned along a common axis. The transformation of the rectilinear reciprocating motion takes place, in a central crank-chamber (5), through one or several connecting rods (10a, 10b), located on either side of the rod (7), driving one or several cranks (12a, 12b), capable of being coupled on a common shaft (17) by gear or any other system. Only the rotating mechanical energy is transformed by the rod/crank system. The compression/expansion energy is directly by the rigid rod. That arrangement enables to separate by sealing partitions (18a, 18b) the crank-chamber (5) from the piston compartments (19a, 19b), which serve to compress fresh air before intake into the combustion chambers (B) through the pistons (6a, 6b). The gas path is simplified, the central part is maintained at room temperature. The burnt gas exhaust is ensured by the cylinder heads (3a, 3b) arranged at the ends of the cylinders (2a, 2b). The cool gases are never in contact with the hot gases, thereby improving performance. Fuel injection is carried out in the cylinder heads (3a, 3b) using compressed air pressure in the combustion chambers (B), the amount injected being mechanically and electronically controlled. The architecture of the engine enables easy control of the set of parameters ensuring proper non-polluting combustion with reduced fuel consumption.

摘要： A simple propulsion engine utilizing unheated atmospheric air as the propellant, and driven by a single cycle engine with internal combustion cylinder and free piston is disclosed. A plain piston(3a, 3b, 4) is slidably displaceable in an elongated cylinder containing cylinder heads (21a, 21b) on opposite ends. The piston receives a combustive impulse at each end of its stroke. The cylinder also has exhaust/inlet ports (9a, 9b, 19a, 19b) and propulsive nozzles at each end with relevant valves and actuators (13a, 13b, 22a, 22b, 26a, 26b) to effect the requisite timing of the combustion, air induction, and propulsion functions. The preferred embodiment combines a free piston with an annularly arranged thrust piston to divide a dual-diameter cylinder into two combustion chambers and two thrust chambers. Scavenge feeder lines connecting the thrust chambers to the combustion chambers via check valves provide exhaust scavenging, additional thrust output through exhaust nozzles, and feeding of fresh air into the combustion chambers.

The injector apparatus (310) includes a first piston (314) defining a first working area facing an associated chamber (332), a high pressure piston (318) defining a high pressure working area facing a high pressure chamber (319), and a control piston (317) defining a control piston working area facing a control chamber (315). The first piston (314) is moveable with a body of the injector apparatus (310) to compress fluid in the high pressure chamber (319) using the high pressure piston (318), while movement of the first piston (314) is selectively controllable by controlling the fluid in the control chamber (315). The first working area is larger than the control piston working area and the control piston (317) working area is larger than the high pressure working area.
