The invention relates to a waste-heat utilization assembly (1) of an internal combustion engine (50), comprising a circuit (2) that conducts a working medium, wherein a pump (6), a distribution valve block (7), two evaporators (10, 11), an expansion machine (3), and a condenser (4) are arranged in the circuit (2) in the flow direction of the working medium. The two evaporators (10, 11) are arranged in a parallel connection, and the parallel connection begins at the distribution valve block (7) and ends at a node point (8). A temperature sensor (21) for determining the outlet temperature of the working medium at the expansion machine (3) is arranged between the expansion machine (3) and the condenser (4).
