An intake system () of an internal combustion engine includes an intake manifold () with at least two feed pipes () connected with cylinder head intake ports of the internal combustion engine and includes at least one intermediate chamber () having connections () to an interior volume () of each feed pipe (). Each connection () can be opened or closed by way of an intake control valve.

Intake system of internal combustion engine

An intake system () of an internal combustion engine includes an intake manifold () with at least two feed pipes () connected with cylinder head intake ports of the internal combustion engine and includes at least one intermediate chamber () having connections () to an interior volume () of each feed pipe (). Each connection () can be opened or closed by way of an intake control valve () having a switch chamber () which has a connection () to means for creating a pressure in the switch chamber (). The switch chamber () is separated from the interior volumes () of the feed pipes () and the intermediate chamber () by a diaphragm ().

An oil pan for attachment to the lower wall of the engine block housing of an internal combustion engine by bolts in such a way that lubricating oil is stored in the oil pan and transported from the oil pan to various parts of the engine to be lubricated by a suction line connected to an oil pump, in which excess oil flows back directly into the oil pan. The oil pan has a pan body () which is formed of a synthetic material and is closed along its upper portion by a connecting plate (), also formed of a synthetic material, in which each of the two surfaces of the connecting plate is provided with a circumferential seal () that is cast onto the plate to ensure a tight seal between the pan body () and the engine block. The bottom portion of the connecting plate () extends as a tubular connecting piece (), which is provided at its free end with a filter screen (), and which forms a segment of the suction line.
