Abstract
The invention provides an exhaust heat utilization device for a combustion engine with an exhaust heat utilization circuit, in which a working medium circulates. An evaporator is arranged in the exhaust heat utilization circuit for evaporating the working medium, which can be supplied with exhaust gas of the combustion engine, with an expansion machine arranged in the exhaust heat utilization circuit downstream of the evaporator for expanding the working medium. A condenser is arranged in the exhaust heat utilization circuit downstream of the expansion machine for condensing the working medium. A delivery device is arranged in the exhaust heat utilization circuit downstream of the condenser for driving the working medium in the exhaust heat utilization circuit and with a heat storage unit. The device is given an improved functionality when the heat storage unit is incorporated in the exhaust heat utilization circuit and can be supplied with working medium.
