Abstract

The invention relates to a carburetor arrangement for an internal combustion engine (1) which drives a work apparatus. The engine (1) has an intake channel (3) leading through a carburetor (2). The intake channel (3) includes an intake opening (4) on the side of the carburetor (2) facing away from the engine (1). A baffle wall (5) is provided and covers the intake opening (4) at least partially. The baffle wall (5) is mounted transversely to the longitudinal axis (6) of the intake channel (3) at a spacing to the intake opening (4). The baffle wall (5) and the intake opening (4) define a baffle enclosure (7) disposed therebetween. At least a first component part (8) of the baffle wall (5) is inclined with respect to the longitudinal axis (6) of the intake channel (3) in such a manner that fuel droplets (9), which exit from the intake channel (3) and which impinge on the first component part (8) of the baffle wall (5), form a fuel film (10).
