Two-stroke motor and method for operating two-stroke motor

The invention relates to a two-stroke motor and a method for operating a two-stroke motor, in particular a two-stroke motor having a cylinder in which a combustion chamber is formed. A combustion chamber is defined by a piston reciprocatingly guided in a cylinder, which drives a crankshaft. A first suction channel is provided, which opens into the crankcase interior with a first suction channel opening. At least one overflow channel opens through an overflow window to a cylinder bore of the cylinder and through an open mouth into the crankcase inner chamber. At least one second suction channel is provided for supplying pre-purge air into the at least one overflow channel. The first suction channel and the second suction channel are designed to supply air. An injection valve is provided on the crankcase, which is designed to inject the total amount of fuel to be supplied to the two-stroke motor directly into the crankcase interior. A method for operating a two-stroke motor defines that the total amount of fuel
