Abstract

The coolant circuit downstream of the coolant pump 1 of an internal combustion engine is divided intoa) an engine cooling loop (I) through the internal combustion engine (2) with a crankcase and a cylinder head,b) an exhaust loop (II) with an exhaust manifold (3) and a turbocharger (4) andc) a heat exchanger loop (III) with a charge heat exchanger (9) and a raw water heat exchanger (8)in a parallel configuration. These loops are recombined upstream of the coolant pump (1).
