<p>Internal combustion engine comprising a cylindrical work chamber (1) with a piston (3) sliding therein, said work chamber being closed by a cylinder head (4), a device (5) operating in two stroke mode, for injecting liquid fuel atomized under high pressure, a system for loop scavenging through the cylinder head and two valves having the same cylindrical form and axes. The outer inlet valve (7) cooperates with a cylinder head seat (15), the other valvebeing an exhaust valve (6) of tubular shape which has a surface bearing against a seat (16) formed in the lower portion of the inlet valve (7). The inle valve opens into the work chamber and the exhaust valve opens in the opposite direction, thereby delimiting, between them, an exhaust passage (8). The injection device (5) opens into the work chamber substantially at the centre of a central hub (21) on the cylinder head, the exhaust valve (6) sliding along said hub.</p> |
