Embodiment Construction

[0050] according to figure 1 , an internal combustion engine 1 preferably for use in a motor vehicle, comprising a block 2 containing a combustion chamber 3 in a cylinder (not shown in further detail). The internal combustion engine comprises a fresh air system 4 for supplying fresh air to the combustion chamber 3 . Furthermore, the internal combustion engine 1 is equipped with an exhaust system 5 for exhaust gas from the combustion chamber 3 . The internal combustion engine 1 is supercharged, for which purpose it has an exhaust-gas turbocharger 6 which has a supercharger 7 and a turbine 8 in a conventional manner. The supercharger 7 is integrated into the fresh air system 4 . Turbine 8 drives supercharger 7 and is integrated into exhaust system 5 .

[0051] The fresh air system 4 comprises an air filter device 9 connected via a first connection 10 to the inlet of the supercharger 7 so that filtered fresh air with ambient temperature reaches the supercharger 7 . A second c...

Abstract

The invention relates to a fresh air supply device (26) for an internal combustion engine (1), in particular in a motor vehicle, comprising a filter element (37) arranged in a filter compartment (35) and a filter element (37) arranged in a cooler compartment (36 ) in the charge air cooler (12). In order to keep production costs low, a one-piece housing (34) is provided which integrally comprises the filter compartment (35) and the cooler compartment (36), the charge air cooler (12 ) has a coolant inlet (61), a coolant outlet (62), and an internal coolant path that connects the coolant inlet (61) to the coolant outlet (62), and thermally Transfer-coupled to a charge air path extending inside the housing (34) and through the cooler compartment (36).

Description

technical field [0001] The invention relates to a fresh air supply device for an internal combustion engine, in particular an internal combustion engine for a motor vehicle. Background technique [0002] The fresh air supply device supplies fresh air to the supercharged internal combustion engine and generally comprises a filter element arranged in a filter compartment and a charge air cooler arranged in a cooler compartment. For supercharging the fresh air, for example, the internal combustion engine comprises a compressor or an exhaust-gas turbocharger with a supercharger connected to the fresh air system of the internal combustion engine and a turbine drive-connected to the supercharger, The turbine is integrated into the exhaust system of the internal combustion engine. [0003] A fresh air supply device is known from DE 19604738 A1 which comprises a filter compartment for receiving a filter element and a cooler compartment for receiving a charge air cooler in a common ...
