Abstract
Abstract An internal combustion engine with auxiliary machines driven by a V-belt and pulley from the engine the engine and the pulley being enclosed by a sound suppressing encapsulation, the auxiliary machines being mounted externally of the encapsulation, the V-belt extending at least partly through a sound absorbing funnel-shaped leadthrough to the pulley, the funnel-shaped leadthrough providing a silencer unit and a passageway for the intake of cooling air into the encapsulation.
