ABSTRACT:
An intake arrangement for an internal combustion engine includes an intake channel (80) which connects the clean side (81) of an air filter (41) to the engine. The intake channel (80) is subdivided by a partition wall (11) into an air channel (8) and a mixture channel (21). A throttle flap is mounted in the intake channel (80). A fuel opening (27, 28) for supplying fuel opens into the mixture channel (21). In order to avoid a throw back of fuel from the mixture channel (21) into the air channel (8), it is provided that the clean side (81) of the air filter (41) is divided into two chambers (82and83) and the mixture channel (21) opens into the first chamber (82) and the air channel (8) opens into the second chamber (83).
