Abstract
An internal combustion engine includes a sound-proofing casing, and a silencer arranged in a separate chamber within the casing such that it does not touch the walls of the separate chamber. Fresh cooling air passes through an inlet opening from the interior of said casing into the separate chamber, and spent cooling air from said separate chamber passes back into the air flowing within the casing, whereby all of the spent air flows from the interior of the sound-proofing casing through an outlet opening of said casing to the outside.
