Claim:
An internal combustion engine, comprising: a cylinder having a combustion chamber that is delimited by a piston reciprocally mounted in the cylinder, wherein said piston drives a crankshaft that is rotatably mounted in a crankcase, and wherein at least one transfer channel fluidically connects the crankcase with the combustion chamber in prescribed positions of said piston; an intake channel that opens into said crankcase, wherein a first fuel channel opens into said intake channel and is adapted to supply fuel to said intake channel as a function of an underpressure in said intake channel, and wherein during an idling operation of said engine said intake channel is adapted to receive largely fuel-free air; an auxiliary channel that opens into said at least one transfer channel, wherein a second fuel channel opens into said auxiliary channel and is connected to a storage reservoir for fuel; and at least one valve for controlling a quantity of fuel to be supplied to said internal combustion engine via said auxiliary channel wherein during said idling operation supply of fuel to said engine is adapted to be effected essentially via said auxiliary channel.
