The pneumatic device for injecting fuel into the combustion chamber (4) includes an orifice (18) emerging in the combustion chamber (4), a means (19) for the controlled opening and closing of the orifice (18), a pipe (20, 20a) for connecting the closable orifice (18) to a volume of compressed air, and a fuel injector (22). The means (19) for opening and closing the orifice (18) of the combustion chamber (4) consists of a rotary plug (19) of substantially cylindrical shape, the axis of rotation of which is located in a plane perpendicular to the axis of the cylinder (1). The plug (19) is pierced by a transverse channel (21) for placing the connection pipe (20, 20a) and the combustion chamber (4) in communication. The rotational drive of the plug (19) is provided by a means (25) from the rotation of the crank shaft (6) during the operation of the engine. <IMAGE>
