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.

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.
