ABSTRACT:
A method and an arrangement are suggested for determining a temperature quantity in a mass flow line which includes a throttle position and to which an additional gas mass flow is supplied after the throttle position. The temperature ahead of the throttle position is determined on the basis of the portion of the additional gas mass flow in the total flow in dependence upon the temperature of the mixture of the two gas mass flows as well as the temperature of the introduced gas mass flow.
