Summary Die Erfindung betrifft einen Verbrennungsmotor (1) mit zumindest einer Abgasleitung (2), in der ein Wärmetauscher (4) angeordnet ist, und mit einer dem Wärmetauscher (4) umführenden Bypaßleitung (13). Der Verbrennungsmotor (1) weist einen Motorölkreislauf (6) auf. Dem Wärmetauscher (4) ist zumindest stromaufwärts eines Abgasstromes ein Mehrwegeventil (12) vorgeschaltet. Der Wärmetauscher (4) ist in dem Motorölkreislauf (6) integriert, so daß das Motoröl in einer Warmlaufphase des Verbrennungsmotors (1) mittels der Abgaswärme aufgeheizt wird.
Combustion engine comprises an exhaust gas line (2) containing a heat exchanger (4) connected to a multiple way valve (12) upstream of an exhaust gas stream. The heat exchanger is integrated into an engine oil cycle (13) so that the oil is heated in a hot running phase of the engine using the exhaust gas heat. Preferred Features: The multiple way valve is formed as a three-way valve connected with two connections to the exhaust gas line and with one connection to a bypass. A siphon (14) is connected to the heat exchanger.
