Embodiment Construction

[0042] figure 1 with figure 2 Shown are different views of the air-guiding device configured as the intake distribution duct 10 . The intake distribution pipe 10 is appropriately drawn such that components that are hidden or arranged inside the intake distribution pipe 10 are shown in dashed lines. The intake manifold 10 can be part of an internal combustion engine (not shown) of a motor vehicle, in particular a commercial vehicle. The commercial vehicle can be, for example, a bus or a truck.

[0043] The intake distribution pipe 10 has a pipe body 12 . In this duct body 12 there extend an air distribution channel 14 , a plurality of individual ventilation channels 16 and a converging ventilation channel 18 . The pipe body 12 can be, for example, a metal casting, for example made of an aluminum alloy.

[0044] The intake manifold 10 can be mounted, in particular screwed, on the cylinder head. In other embodiments, the intake distribution pipe 10 may be cast directly on ...

Abstract

The present disclosure relates to a device for conducting air, in particular inlet air distributor pipe (10), for an internal combustion engine with a plurality of cylinder heads (26). The device forconducting air includes a pipe body (12). The pipe body (12) has an air distribution channel (14) with a plurality of outlet openings (22) for connecting to a plurality of inlet channels (28) of the plurality of cylinder heads (26). The pipe body (12) includes a plurality of single venting channels (16) for connecting to a plurality of coolant chambers (30) of the plurality of cylinder heads (26)for venting the plurality of coolant chambers (30). The pipe body (12)additionally includes a collective venting channel (18), the plurality of single venting channels (16) discharging therein.

Description

technical field [0001] The invention relates to an air-guiding device for an internal combustion engine, in particular an intake manifold. Background technique [0002] The cylinder head can have coolant flow through it for cooling. The coolant flows in a so-called coolant chamber or coolant core, which is also called a water core when water is used as coolant. When using a single-cylinder cylinder head (single cylinder head), each cylinder head has its own coolant chamber. [0003] In the coolant chamber of the cylinder head, the coolant in the coolant chamber boils locally at a portion where the flow rate is low and the local temperature is high. At the same time steam bubbles are formed. Said vapors must escape from the coolant chamber, that is to say the coolant chamber must be ventilated. [0004] EP 1 514 020 A1 discloses a cylinder head of a reciprocating internal combustion engine with a cylinder head lower part, a cylinder head cover and a frame for accommodatin...
