Abstract

Una testata per motori a c.i. con dispositivo per l'iniezione diretta di carburante assistita pneumaticamente entro almeno un cilindro dotato di una apertura di valvola con relativa valvola, essendo previsti mezzi per l'alimentazione di carburante entro una camera che da un lato è collegata alla valvola e dall'altro è collegata ad un condotto di alimentazione dell'aria, entro la camera agendo inoltre un pistone per iniettare entro il cilindro, attraverso l'apertura della valvola, la miscela aria combustibile generata nella camera, il pistone essendo meccanicamente azionato da una trasmissione positiva azionata dall'albero motore, ove in corrispondenza di una estremità del condotto affacciata alla camera è disposto un elemento valvolare. L'elemento valvolare è costituito da una o più lamelle o da un disco rotante.A cylinder head for c.i. with pneumatic assisted device for direct fuel injection within at least one cylinder equipped with a valve opening with relative valve, means for supplying fuel are provided within a chamber which on one side is connected to the valve and on the other is connected to an air supply duct, inside the chamber also acting a piston to inject into the cylinder, through the valve opening, the mixture of combustible air generated in the chamber, the piston being mechanically driven by a positive transmission operated by the motor shaft, where a valve element is arranged at one end of the duct facing the chamber. The valve element consists of one or more lamellae or a rotating disc.
