Abstract (en)
[origin: FR2745328A1] An improvement to loop-scavenged two-stroke internal combustion engines with an intake valve (7) engaging a seat (10) for fresh air intake, and an exhaust valve (8) engaging a seat (13) for combustion gas exhaust, is disclosed. The valves are arranged in such a way that the fresh air intake scavenges a susbtantial part of the burnt gases. In at least one of said valves, the valve surface (21) located downstream from the valve face (9) and the surface (23) of the downstream extension of said seat (10) are configured in such a way that they form a substantially isentropic diffuser.
