Abstract: The present invention relates to an internal-combustion engine comprising a combustion chamber provided with a single intake valve (2), a single exhaust valve (3), two plugs (4a, 4b) and a fuel injector (5). Furthermore, the combustion chamber comprises means for forming an aerodynamic swirling motion structure of the intake gas in the combustion chamber. Besides, fuel injector (5) is oriented so as to inject the fuel into the central area of the combustion chamber in the direction of the aerodynamic swirling motion structure.

Abstract: The present invention relates to a combustion chamber of a combustion engine. The combustion chamber comprises a single intake valve (2), a single exhaust valve (3), a fuel injector (5) and two plugs (4). According to the invention, the combustion chamber is substantially elliptical (6) and the components of the combustion chamber are arranged as follows: valves (2, 3) are located at the ends of the major axis (8) of ellipse (6), plugs (4) are located close to the minor axis (9) of ellipse (6), fuel injector (5) is located on the periphery of ellipse (6) between intake valve (2) and a plug (4).

Abstract: The present invention relates to an optical engine comprising a cylinder head of an industrial engine and a transparent cylinder. According to the invention, the transparent cylinder is tightly applied to the cylinder head by pneumatic means, a jack for example, allowing easy dismantling and cleaning of the cylinder. Furthermore, the industrial cylinder head is mounted on a support secured to the frame of the <<engine bottom>> by jacks or equivalent means, at least one of these means being pneumatic for opening the engine.
