Abstract: PCT No. PCT/FR91/00056 Sec. 371 Date Oct. 11, 1991 Sec. 102(e) Date Oct. 11, 1991 PCT Filed Jan. 30, 1991 PCT Pub. No. WO91/12419 PCT Pub. Date Aug. 22, 1991.In a two-stroke internal combustion engine with a compression-ignition of Diesel type, the exhaust valve or valves (10) are so arranged as to allow flow on at least the major part of their periphery; the piston (3) cooperates with the ceiling of the cylinder head (6) in such manner as to leave, in the vicinity of top dead center, only the required operational clearance between the piston (3) and the part of the ceiling of the cylinder head in which the exhaust valve or valves (10) is or are placed; and a cylindrical recess (14) in which is placed the head (13) of the inlet valve or valves (8) and into which a fuel injector discharges, is arranged in such manner as to constitute practically alone the combustion chamber (7) when the piston (3) is in the vicinity of top dead center.
