摘要： The present invention refers to a device (1) for water circulation in a cooling circuit of an internal combustion engine (3). The device comprises a pump and a suction chamber (8) which develop in a circular way around the axis of the pump impeller. The device comprises also a water manifold (50) that can be connected to the outlet of a radiator (40) of said cooling circuit. The device comprises a first duct (5) connected to the manifold and a first opening (5′) which defines an axial inlet for said first flow in said chamber (8). The device comprises also a second duct (6) connected to the manifold (50) and to the suction chamber (8′) by means of a second opening (6′). The latter defines a tangential intake for water, so that it is subject to a rotation around the axis of the impeller. The device further comprises flow rate partition means (9) suitable to vary the flow rate of the water circulating in both ducts (5,6) as a function of the operating conditions of said engine.

摘要： An internal combustion engine with controlled ignition comprises a cylinder, a relative piston, and a head between which a combustion chamber is operationally defined. The cylinder and the piston define a first prismatic coupling. The engine also comprises a pre-chamber made directly inside the combustion chamber, and a male element stably connected to an upper surface of the piston to penetrate the pre-chamber at least in one portion of the relative motion of the piston in the cylinder. A spark plug is arranged to look out into the pre-chamber.
