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.
Claims20
An internal-combustion engine comprising at least one cylinder in which a piston moves, the cylinder being associated with a combustion chamber provided with a single intake valve, a single exhaust valve, a fuel injector and two plugs, wherein the combustion chamber comprises means for forming an aerodynamic motion structure of the intake gas with turbulences within the combustion chamber, and the fuel injector is oriented so as to inject the fuel into the central area of the combustion chamber between the two plugs, in the direction of the aerodynamic motion structure of the intake gas.
