Carburetor arrangement for an internal combustion engine

摘要

A carburetor arrangement is provided for an internal combustion engine that is to be started with a pull cord. A fuel channel that is connected with a fuel-filled storage space opens into and supplies fuel to an intake channel portion as a function of the underpressure in the intake channel portion. The underpressure in the intake channel portion is increased during the start-up process via a start-up mechanism. To keep the engine ready to run with the start-up mechanism engaged, a control valve is disposed between the storage space and where the fuel channel opens into the intake channel portion. The control valve is opened or closed by a control unit as a function of the speed of the internal combustion engine.
