Internal combustion engine with exhaust gas turboJt ^ 3wr '^, ^

The invention relates to an internal combustion engine with an exhaust gas turbocharger and intercooler.

In known internal combustion engines, the pre-compressed charge air from the exhaust gas turbocharger to the intercooler through air lines supplied, which represent independent components. These lines take, especially in internal combustion engines with high Charging degrees, take up a lot of installation space and have to be laid in aerodynamically unfavorable shapes due to lack of space the. The invention is based on the object of a space-saving and aerodynamically favorable air duct between the exhaust gas turbocharger and intercooler to allow. This is according to the invention solved in that the exhaust gas turbocharger "<and the intercooler are arranged on a common device carrier, which is designed as part of the air line between the exhaust gas turbocharger and intercooler is.

The proposal according to the invention achieves the gate part, that an extremely small installation space is required without having to accept lines that are unfavorable to the flow. After another The arrangement of the air passage means that the configuration of the invention can be symmetrical to that in the direction of flow Central plane of the device carrier of the further Yorteil can be achieved that regardless of the location of the air outlet of the

Exhaust gas turbocharger, on the right or, on the left, ane short space-saving connection line can be used between the exhaust gas turbocharger and the equipment rack.

The device carrier is simple as an independent component of the machine type adapt. You are therefore free in the structural design of this line part. There can be funds without significant additional expenditure be provided that improve the flow conditions and the cooling of this part. In further embodiments of the invention it is therefore proposed that the cross-section of the air passage in the equipment rack to the intercooler widens, whereby a particularly streamlined and low-loss entry of the charge air into the charge air cooler is made possible. It is also proposed to connect the walls of the air passage of the device carrier to this only at one end. This allows them to get involved the other end freely expand under the influence of heat. Finally can It may also be advantageous to cool the walls of the air passage of the device carrier. In this case, in the equipment rack Cold rooms or cooling fins provided.

In the drawings, for example, embodiments of the invention are shown.

Fig. 1 shows a partial section of the arrangement of an exhaust gas turbocharger to the intercooler.

Fig. 2 shows, in addition to Fig. 1, the alignment of cold rooms in the equipment rack.

Fig. 3 shows a section along the line III - III in Fig. 2.

An equipment carrier 2 is flanged to an internal combustion engine 1, which is designed as part of an air line 3 between an exhaust gas turbocharger 4 and a charge air cooler 5. The exhaust gas turbocharger 4 and the charge air cooler 5 are attached to the equipment rack 2 and with a flange 6 or 7 with an air passage 8 of the equipment rack tied together. The cross-section of the air passage in the equipment rack expands towards the charge air cooler, which creates a particularly streamlined system metrologically favorable solution is achieved. The walls of the air passage 8 are connected to the intercooler side 7 with the equipment carrier, while they are free on the exhaust gas turbocharger side 6 by a Opening of the device carrier are performed.

In Fig. 2 the walls for the air passages are on both Ends firmly connected to the device carrier, whereby the walls of the air passage 8 with the walls of the device carrier 2 a Form refrigerator 9. The coolant is supplied through an opening

10, the coolant is drained through an opening 11. '

Fig. 3 shows a section along the line III - III in Fig. 2, from which it can be seen that the air passage is symmetrical su the center plane 12 of the device carrier lying in the direction of flow 2 is arranged. With 13 cooling fins are designated, which in the air passage 8 are arranged and cause a pre-cooling of the charge air.
