Abstract
A waste heat utilization apparatus is provided with a Rankine cycle and a power transmission mechanism that transmits power regenerated by an expander to an engine. The power transmission mechanism includes an expander clutch that interrupts or permits the transmission of the power from the expander to the engine. The expander includes a rotational speed sensor that detects a rotational speed of the expander. An increase in friction of the expander is detected on the basis of an increase in the rotational speed of the expander detected by the rotational speed sensor when the expander clutch is disconnected.
