  • Gas intake device having two asymmetrical intake ducts
    Patent number: 11578644
    Abstract: The present invention relates to a gas intake device (1) for a cylinder of an internal-combustion engine. The gas intake device comprises two intake pipes (5a, 5b), two intake valves (4), two intake valve calibration parts (6a, 6b) and, in each intake pipe (5a, 5b), means for forming an aerodynamic gas motion of tumble type in the cylinder. Furthermore, for each intake pipe (5a, 5b), the intersection between intake pipe (5a, 5b) and calibration part (6a, 6b) occurs along a line non-parallel to the plane of the fire face. Besides, the inclination angle of this intersection is different for each pipe (5a, 5b).

  • Gas inlet duct generating an aerodynamic movement of gas within a cylinder
    Patent number: 11415042
    Abstract: The present invention relates to a gas intake pipe (2) for a cylinder of a thermal engine. The pipe comprises means for diverting the gas so as to generate a tumble type aerodynamic motion of the gas within the cylinder. The diversion means comprise at least a “ramp” shape (6) on the lower profile (12) of the pipe and a concave zone on the upper profile (10) of intake pipe (2).

  • TWO-VALVE INTERNAL-COMBUSTION ENGINE
    Publication number: 20190101047
    Abstract: The present invention relates to an internal-combustion engine comprising at least two cylinders wherein a piston in connection with a combustion chamber moves. Said combustion chamber comprises a single intake valve (SA), a single exhaust valve (SE), a single fuel injector (ID), two spark plugs (Al) and means for creating a swumble flow in said chamber.
