Abstract

Die Erfindung betrifft eine AGR-Regelung mit mechanischer Temperaturregelung. Eine derartige AGR-Regelung wird an Brennkraftmaschinen (1) mit einer Ansaugleitung (2) zur Zuführung der Ansaugluft zu den einzelnen Brennräumen (3), mit einer Abgasleitung (4) zur Abführung der Abgase aus den Brennräumen (3) und mit einer die Ansaugleitung (2) und die Abgasleitung (4) verbindenden Abgasrückführleitung (5) verwendet, wobei in der Abgasleitung (4) ein Temperatursensor angeordnet ist, dessen Temperaturwert zur Steuerung der durch die Abgasrückführleitung (5) rückgeführten Abgase verwendet wird. Erfindungsgemäß ist der Temperatursensor ein mechanisches Thermoelement (6), dessen temperaturabhängige Auslenkung eine Abgasklappe (7) mechanisch steuert.

The invention relates to an EGR control with mechanical temperature control. Such an EGR control is applied to internal combustion engines (1) with an intake line (2) for supplying the intake air to the individual combustion chambers (3), with an exhaust pipe (4) for discharging the exhaust gases from the combustion chambers (3) and with a suction line (2) and the exhaust gas line (4) connecting exhaust gas recirculation line (5) is used, wherein in the exhaust pipe (4), a temperature sensor is arranged, the temperature value for controlling the exhaust gas recirculation line (5) recirculated exhaust gases is used. According to the invention, the temperature sensor is a mechanical thermocouple (6) whose temperature-dependent deflection mechanically controls an exhaust gas flap (7).
