Cooling arrangement for a chargeable internal combustion engine

Abstract

Embodiments for a cooling arrangement are provided. In one example, a cooling arrangement comprises a low-temperature circuit for charge-air cooling of a turbocharger of an internal combustion engine, an engine cooling circuit for cooling the internal combustion engine, and a charge-air cooler arranged in the low-temperature circuit and connected in a fluid-conducting manner on a coolant inlet side, via a first valve device, to the low-temperature circuit and to the engine cooling circuit, and on a coolant outlet side, via a second valve device, to the low-temperature circuit and to the engine cooling circuit. In this way, coolant from the engine may heat the charge-air cooler under certain conditions.

Description

[0001] related application [0002] This application claims priority from German Patent Application No. 102011076457.7 filed May 25, 2011, the entire contents of which are hereby incorporated by reference. technical field [0003] The invention relates to a cooling device for a superchargeable internal combustion engine. Background technique [0004] The cooling device is used, for example, in an internal combustion engine with a turbocharger, in particular a motor vehicle engine, in order to cool the internal combustion engine by means of an engine cooling circuit and to feed the supercharging to the internal combustion engine by means of a low-temperature cooling circuit via the turbocharger Air. [0005] Modern superchargeable internal combustion engines, in particular superchargeable diesel engines, usually have a charge air cooling system by means of which the air required for supercharging the internal combustion engine is cooled. In this case, a charge air cooling s...
