ABSTRACT:
An internal combustion engine has an engine block, an oil pan and a sound insulating capsule shrouding the engine block. The engine block and the oil pan have circumferential mounting faces oriented towards one another. A mounting arrangement includes a sound dampening intermediate layer situated between the mounting faces for a noise-dampened connection of the oil pan with the engine block and with a lower terminal zone of the capsule. The oil pan is held by the lower terminal zone of the capsule and the capsule is supported by a component other than the internal combustion engine. The intermediate layer is constituted by a gasket which has at least one fold to take up relative motions between the engine block and the oil pan during operation of the internal combustion engine.
