Abstract:
A two-stroke engine comprising:a cylinder in which is formed a combustion chamber that is delimited by a piston that is reciprocatingly disposed in the cylinder, wherein by means of a connecting rod the piston drives a crankshaft that is rotatably mounted in a crankcase, wherein said crankcase is provided with an air inlet for combustion air, which passes from said crankcase into said combustion chamber via at least one transfer channel which at one end opens into said combustion chamber via a transfer window and at another end communicates with said crankcase, wherein said cylinder is provided with an exhaust port for the discharge of exhaust gases from said combustion chamber and, approximately across from said exhaust port, with an intake port that forms one end of a feed channel that is provided for supplying a fresh mixture, wherein another end of said feed channel opens into said crankcase, wherein said intake port opens into said combustion chamber and when viewed in a stroke direction of said piston towards an upper dead center position thereof, said intake port of said feed channel is disposed above said air inlet into said crankcase; a mixture-forming device for a fuel/air mixture, wherein between said ends thereof, said feed channel communicates with said mixture-forming device; and a component that is external to said cylinder, wherein at least a portion of said feed channel is disposed in said external component.
