Estimating the term…
The invention relates to a circuit arrangement (K) comprising a low-temperature circuit (NK) for cooling charge air (13) that is fed to a motor (8) in a motor vehicle equipped with a turbocharger. According to the invention, the charge air (13) is compressed in two stages in a first low-pressure turbocharger (1) and a second high-pressure turbocharger (2). To cool the charge air (13) a first cooler (3) is provided downstream of the low-pressure turbocharger (1) and upstream of the high-pressure turbocharger (2) and a second cooler (4) is provided downstream of the high-pressure turbocharger (2) and upstream of the motor (8). The invention also relates to a method for operating a circuit arrangement (K) of this type.
A circuit arrangement comprising a low-temperature circuit (NK) for cooling charge air that is fed to an engine in a motor vehicle equipped with a turbocharger, wherein the charge air is compressed in two stages in a first low-pressure turbocharger and a second high-pressure turbocharger, where, in order to cool the charge air, a first cooler is provided downstream of the low-pressure turbocharger and upstream of the high-pressure turbocharger, and a second cooler is provided downstream of the high-pressure turbocharger and upstream of the engine.
