Embodiment Construction
[0093] For supplying the cylinders with charge air, the internal combustion engine has an air intake system 1 and, for supercharging the cylinders, an exhaust-gas turbocharger comprising a turbine arranged in the exhaust-gas discharge system (not shown) and a compressor 2 arranged in the intake system 1 . The compressor 2 is a radial compressor 2b in a housing 2c, the impeller 2d of which is mounted on a rotatable shaft.
[0094] The compressor 2 of the exhaust-gas turbocharger has an inlet area 2a which extends coaxially with respect to the axis of the compressor 2 and which is designed so as to approach the compressor 2 of the exhaust-gas turbocharger The flow of charge air of 1 extends substantially axially, and the part of the intake system 1 upstream of the compressor 2 has no change in direction.
[0095] The internal combustion engine is also equipped with an exhaust gas recirculation device comprising a recirculation line branching from the exhaust gas discharge syste...

A supercharged internal combustion engine having a compressor and a method for operating the internal combustion engine of said type are disclosed. The invention relates to a supercharged internal combustion engine having: an intake system (1) for supplying supercharged air; an exhaust gas discharge system for discharging exhaust gas; and at least one compressor (2) arranged for compressing a flowof supercharged air in the intake system (1), the compressor comprising at least one impeller (2d) equipped to a rotatable shaft in a compressor housing (2c) and equipped with impeller blades. It isan object of the present invention to provide an internal combustion engine of said type, by means of which the formation of condensate in a compressor housing (2c) can be hindered. This is achieved by an internal combustion engine having the characteristics that the compressor housing (2c) is equipped with a phase change material (4) upstream of the at least one compressor impeller (2d), the phase change material (4) being present as a liquid phase or as a solid phase, the phase change material (4) absorbing or releasing heat during the phase change.
Description
technical field [0001] The invention relates to a supercharged internal combustion engine having: an air intake system for supplying charge air; an exhaust gas discharge system for discharging exhaust gas; and at least one compressor arranged for compressing For pressurized air flow in an air system, the compressor comprises at least one impeller fitted to a rotatable shaft in the compressor housing and equipped with impeller blades. The invention also relates to a method for operating an internal combustion engine of the type described. Background technique [0002] An internal combustion engine of the described type is used as a motor vehicle drive unit. Within the context of the present invention, the term "internal combustion engine" includes diesel engines and Otto cycle engines, but also hybrid internal combustion engines, i.e. internal combustion engines operating with a mixed combustion process and a hybrid drive which, in addition to the internal combustion engine,...
