Low-temperature cooling circuit for internal combustion heat engine in motor vehicle, has recirculated exhaust gas cooling assembly connected in series with supply gas cooling assembly whose coolers are connected in parallel

摘要

The circuit (13) has a supply gas cooling assembly (A) comprising coolers (5, 7) that are connected in parallel. A recirculated exhaust gas cooling assembly (B) comprises a cooler (8b), where the cooling assemblies are connected in series. The supply gas cooling assembly is placed upstream of the exhaust gas cooling assembly in a circulation direction of a coolant e.g. glycol water, in a cooling radiator (14).
