<p>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.</p> |
