Abstract

An air filter arrangement for an internal combustion engine, especially for a two-cycle engine in a manually guided implement such as a power saw, a cut-off machine, etc., and including an air filter element that delimits a first clean chamber. The air filter arrangement has an inlet opening for an air channel and an inlet opening for a mixture channel. A shield is provided for shielding the air filter element relative to the mixture channel. The inlet opening of the air channel and the inlet opening of the mixture channel are interconnected via the shield.
