Abstract

An internal combustion engine surrounded, at least in part, by a sound insulating casing. The casing is closed to the atmosphere with the exception of an inlet opening for receiving air for combustion in the engine. An air filter is coupled to the inlet opening for filtering the air passing through this opening into the interior of the casing.
