ABSTRACT:
Internal combustion engines with a cylindrical working chamber (1) in which there slides a piston (3), and which is closed by a cylinder head (4) with a device (5) for injecting atomized liquid fuel under high pressure and operating on the two-stroke cycle with a loop-scavenging system across the cylinder head, with two axisymmetric valves with coincident axes, one of these, an external, inlet valve (7) interacting with a seat (15) in the cylinder head and the other, an exhaust valve (6), exhibiting a tubular shape with a bearing surface applied against a seat (16) formed at the lower part of the inlet valve (7), the inlet valve opening towards the working chamber and the exhaust valve opening in the opposite direction, in order to delimit an exhaust passage (8) between them, the injection device (5) emerging in the working chamber substantially at the centre of a central hub (21) borne by the cylinder head and about which the exhaust valve (6) slides.
