Embodiment Construction

[0020] by reference figure 1 and 2 Exemplary embodiments are used to explain the present invention in more detail. exist figure 1 and 2 In , two different embodiments of the charging device according to the invention are shown for this purpose, wherein the same reference characters refer to the same structural or functional features.

[0021] exist figure 1 In , a first embodiment of a supercharging device 1 according to the invention or a system consisting of such a supercharging device 1 and an internal combustion engine 10 is shown.

[0022] From figure 1 It is evident that a supercharger device 1 is provided for an internal combustion engine 10 . In this case, internal combustion engine 10 represents an internal combustion engine in a hybrid drive system, wherein internal combustion engine 10 can be operated at different load points approximately along its power curve. When the internal combustion engine 10 is in an unloaded state, it produces only a small exhaust g...

Abstract

The invention provides a device for supercharging an internal combustion engine. A supercharging device (1) for an internal combustion engine (10) having a compressor (V) that is driven by an electricmotor (M) for supercharging the internal combustion engine with air via an air feed passage (L), and an electric energy accumulator (20), which is fed with electric energy via a first power generator(30) that is driven by the internal combustion engine (10). For energy supply, the electric motor (M) is connected to electric energy stored in the energy accumulator (20) to drive the compressor (V)independently of a current operating point on a power curve of the internal combustion engine (10).

Description

technical field [0001] The invention relates to a device for supercharging an internal combustion engine, preferably an internal combustion engine in a hybrid drive system. Background technique [0002] A wide variety of supercharger system configurations are known from the prior art. From DE 10 2016 107870 A1 a method is known for operating an internal combustion engine comprising: at least one high-pressure exhaust gas turbocharger comprising at least one high-pressure exhaust gas turbine with variable turbine geometry and a high-pressure compressor; And at least one low-pressure exhaust gas turbocharger comprising a low-pressure exhaust gas turbine with variable turbine geometry and a low-pressure compressor. [0003] WO 2016074752 A relates to a charging device for an internal combustion engine having a compressor during the compression of a fluid from a first pressure existing on the suction side to a second pressure existing on the pressure side , delivering fluid in...
