Abstract

Für eine flüssigkeitsgekühlte Brennkraftmaschine mit einem Abgasrückführsystem, das einen zu- und abflußseitig mit einem Kühlmittelumlauf einer kennfeldgesteuerten Brennkraftmaschine verbundenen Wärmetauscher zur Kühlung des über ein AGR-Ventil gesteuert in die Maschinen-Ansaugluft rückgeführten Abgases umfaßt, wird erfindungsgemäß vorgeschlagen, daß der AGR-Wärmetauscher zur Nutzung von Abgaswärme zur schnellen Erwärmung des Kühlmittelumlaufes in der Warmlaufphase der Brennkraftmaschine gesteuert betreibbar ist.

Figure 00000001
For a liquid-cooled internal combustion engine with an exhaust gas recirculation system, which comprises a heat exchanger connected on the inlet and outlet sides to a coolant circulation of a map-controlled internal combustion engine for cooling the exhaust gas recirculated into the engine intake air via an EGR valve, the invention proposes that the EGR heat exchanger be used for Use of exhaust gas heat for the rapid heating of the coolant circulation in the warm-up phase of the internal combustion engine can be operated in a controlled manner.
