Embodiment Construction

[0029] figure 1 An internal combustion engine 10 for a motor vehicle, in particular a motor vehicle such as a passenger car, is shown schematically. The internal combustion engine 10 has, for example, an engine housing 12 in the form of a cylinder block, in particular a cylinder crankcase, from which combustion chambers in the form of cylinders 14 , 16 are formed. Cylinder 14 belongs to or forms a first group of cylinders and cylinder 16 belongs to or forms a second group of cylinders. The first group is also referred to as the first portion of cylinders 14 , 16 and the second group is also referred to as the second portion of cylinders 14 , 16 .

[0030] The internal combustion engine 10 has an intake duct 18 through which at least air can flow, for example the air flowing through the intake duct 18 is thereby guided to the cylinders 14 , 16 , in particular into the cylinders. In this case, an air filter 20 for filtering the air is arranged in the intake line 18 . Furtherm...

Abstract

The invention relates to an internal combustion engine (10) for a motor vehicle, comprising: at least one first combustion chamber (14); at least one second combustion chamber (16); at least one firstexhaust gas line element (44) through which exhaust gas from the first combustion chamber (44) can flow; at least one second exhaust gas line element (46), through which exhaust gas from the second combustion chamber (16) can flow; at least one turbocharger (24), which comprises a turbine (34) with a turbine housing (36), which has a first channel (38), into which the first exhaust gas line element (44) opens out, a second channel (40), into which the second exhaust gas line (46) opens out, and at least one third channel (42), through which exhaust gas from the combustion chambers (14, 16) can flow, and a turbine wheel (50) received rotatably in the turbine housing (36); a bypass device (58), which comprises at least one bypass line (60), through which exhaust gas from the first and second exhaust gas line elements (44, 46) can flow and by means of which at least some of the exhaust gas from the first and second exhaust gas line elements (44, 46) can bypass the turbine wheel (50); a valve device (64), which comprises a first valve element (66), by means of which a volume of the exhaust gas from the first and second exhaust gas line elements (44, 46) flowing through the bypass line(60) and bypassing the turbine wheel (50) can be adjusted, and a second valve element (68); and a third exhaust gas line element (48), which opens out into the third channel (42).

Description

technical field [0001] The invention relates to an internal combustion engine for a motor vehicle according to the preamble of claim 1 . The invention also relates to a motor vehicle with such an internal combustion engine. Background technique [0002] Such a motor vehicle internal combustion engine is known, for example, from DE 10 2004 055 571 A1. The internal combustion engine has at least one first combustion chamber, at least one second combustion chamber and at least one first exhaust gas line part through which exhaust gas from the first combustion chamber can flow. In addition, the internal combustion engine has at least one second exhaust gas line part through which exhaust gas from the second combustion chamber can flow. Furthermore, the internal combustion engine includes at least one exhaust gas turbocharger, which includes a turbine with a turbine housing. The turbine housing has a first flow channel, a second flow channel and a third flow channel, wherein t...
