PCT No. PCT/EP94/04061 Sec. 371 Date Oct. 23, 1996 Sec. 102(e) Date Oct. 23, 1996 PCT Filed Dec. 6, 1994 PCT Pub. No. WO95/16113 PCT Pub. Date Jun. 15, 1995The invention concerns a two-stroke internal combustion engine and a method of operating a two-stroke internal combustion engine which includes at least one cylinder (10) with a piston (20) reciprocating therein and with at least one inlet (40) and exhaust duct (70), wherein the inlet duct (40) is arranged in relation to the exhaust duct (70) in accordance with the uniflow scavenging process in such a way that the inlet duct (40) opens into the cylinder in the region of the combustion chamber (30) and wherein a regulating element (50) is provided in the mouth opening region of the inlet duct (40). In that arrangement the regulating element (50) of the inlet duct (40) can be adapted to be controllable and a controllable regulating element (80) can also be arranged in particular in the mouth opening region of the exhaust duct (70). As a result the internal combustion engine can be operated in such a way that the exhaust duct (70) can be closed in dependence on an operating parameter of the internal combustion engine.
