Abstract

Die Erfindung betrifft eine Vorrichtung und ein Verfahren zur Kühlung rückgeführten Abgases einer flüssigkeitsgekühlten Brennkraftmaschine mit Abgasrückführeinrichtung. Die Vorrichtung kennzeichnet sich dabei durch einen Kühleinsatz (7, 7') in einem kühlflüssigkeitsführenden Kanal (6, 6') der Brennkraftmaschine und eine entsprechende Gestaltung des den Kanal (6, 6') im Bereich des Kühleinsatzes (7, 7') begrenzenden Bauteils (1, 28) für eine Kühlung des den Kühleinsatz (7, 7') durchströmenden rückgeführten Abgases durch die den Kanal (6, 6') durchströmende Kühlflüssigkeit. Das erfindungsgemäße Verfahren kennzeichnet sich dadurch, daß das rückgeführte Abgas vor seiner Wiedereinleitung in den Verbrennungsprozeß der Brennkraftmaschine durch einen in einem kühlflüssigkeitsführenden Kanal (6, 6') angeordneten Kühleinsatz (7, 7') hindurchgeleitet und dabei durch die den Kanal (6, 6') durchströmende Kühlflüssigkeit der Brennkraftmaschine gekühlt wird.

Figure 00000001
The invention relates to a device and a method for cooling recirculated exhaust gas from a liquid-cooled internal combustion engine with exhaust gas recirculation device. The device is characterized by a cooling insert (7, 7 ') in a coolant channel (6, 6') of the internal combustion engine and a corresponding design of the channel (6, 6 ') delimiting the area of the cooling insert (7, 7') Component (1, 28) for cooling the recirculated exhaust gas flowing through the cooling insert (7, 7 ') through the cooling liquid flowing through the channel (6, 6'). The method according to the invention is characterized in that the recirculated exhaust gas, before being reintroduced into the combustion process of the internal combustion engine, is passed through a cooling insert (7, 7 ') arranged in a coolant-conducting channel (6, 6') and thereby through the channel (6, 6 ') Cooling fluid flowing through the internal combustion engine is cooled.
