Abstract (en)
[origin: WO2022033827A1] The invention relates to a method for operating an internal combustion engine (10) of a motor vehicle, in which method the internal combustion engine (10) has an intake section (20), through which air can flow and via which at least one combustion chamber of the internal combustion engine (10) can be supplied with the air, a compressor (24) arranged in the intake section (20) with a compressor housing (32) and a compressor impeller (28) arranged rotatably in the compressor housing (32), and a line element (36) which is connected fluidically to the intake section (20) at a first connection point (V1) arranged upstream of the compressor impeller (28) and at a second connection point (V2) arranged downstream of the compressor impeller (28), wherein, in order to heat at least the compressor housing (32), the internal combustion engine (10) is operated in a heating mode, in which air is branched off from the intake section (20) at the second connection point (V2), is introduced into the line element (36), is returned to the first connection point (V1) by means of the line element (36), and is introduced into the intake section (20) at the first connection point (V1).
