Embodiment Construction

[0044] In the internal combustion engine according to the invention at figure 1 The first preferred embodiment shown in has a motor block (Motorblock) 10 of an engine with cylinders 12 , here by way of example five cylinders 12 , wherein each cylinder 12 conducts fluidically and freshly The gas line 14 is connected to an exhaust gas line 16 . As charging device, the internal combustion engine has an exhaust gas turbocharger with a turbine 18 arranged in the exhaust gas line 16 and a compressor 20 arranged in the fresh gas line. The section of the fresh gas line 14 downstream of the compressor 20 is referred to as the charge air section 22 . An air conditioning / shut-off valve 24 is arranged in the charge air section 22 . It contains an actuatable flap which, depending on the position, changes or completely closes off the flow cross-section of the charge air section 22 and serves for air conditioning and for shutting down the internal combustion engine. An air filter 21 is ar...

Abstract

The invention relates to an internal combustion engine comprising a fresh gas line (14) for supplying fresh gas to working cylinders (12) of the internal combustion engine, wherein in the fresh gas line (14) next to a preferably provided compressor (20) of a charging unit, then downstream of the compressor (20) of the charging unit, a mechanically actuated compressor (26) is arranged in a charge air duct (22). An air regulation / shut-off device (24) is arranged in the charge air duct (22), in such a manner that in dependence of a position of the air regulation / shut-off device (24) a gas mass flow in the charge air duct (22) flows entirely or in part via the mechanically actuated compressor (26) or past the mechanically actuated compressor (26).

Description

technical field [0001] The invention relates to an internal combustion engine according to the preamble of claim 1 with a fresh gas line (Frischgasstrang) for supplying combustion air to the working cylinders of the internal combustion engine, wherein the charge air in the fresh gas line A mechanically, in particular electrically driven, compressor is arranged in the section. Background technique [0002] An internal combustion engine with an exhaust gas turbocharger is known from DE 102 02 146 B4, wherein an electrically driven compressor is arranged in the fresh gas line upstream of the charging device, in particular the compressor of the exhaust gas turbocharger . In order to obtain a sufficient air mass flow in small compressors, a bypass channel for the compressor is provided with an additional actuatable flap. However, this valve causes a pressure loss in the fresh gas line. [0003] It is known from "Kraftfahrtechnisches Taschenbuch" (Vieweg+Teubner Verlag, 2011, 2...
