Abstract
The invention discloses a two-stroke internal combustion engine having an engine housing with a crankcase in which a crankshaft is connected to a piston moving in a cylinder, an exhaust port leading from the cylinder space and opening at the level of the lower dead center of the crankshaft, the exhaust port is configured to be closed by a piston when the crankshaft is in its top dead center position, characterized in that it further has a rotary disk with an opening or recess on a part of its circumference, or with a protrusion on a part of its circumference, the rotary disk extending with its circumference into the exhaust port so that the exhaust port is completely closable by the rotary disk.
Claims9
A two-stroke internal combustion engine comprising:
- an engine housing comprising a crankcase separated from a space above a piston;
- a crankshaft in the crankcase is connected to the piston moving in a cylinder;
- an exhaust port leading from the cylinder and opening at a level of a lower dead center of the crankshaft, said exhaust port configured to be closed by a piston when the crankshaft is at a top dead center position;
- and
- a rotary disk (1) with an opening or recess on a part of a circumference thereof, or with a protrusion on a part of the circumference thereof, said rotary disk extending with the circumference thereof into the exhaust port (2) such that the exhaust port (2) is completely closable by the rotary disk (1), said rotary disk (1) being formed as a single piece.
