Method for controlling waste heat utilization device of internal combustion engine, particularly in motor vehicle, involves controlling expansion ratio of Organic Rankine Cycle as function of output of internal combustion engine

摘要

The method involves controlling the expansion ratio of the Organic Rankine Cycle as a function of the output of the internal combustion engine. The expansion ratio of the Organic Rankine Cycle is controlled as a function of the vehicle speed , the ambient temperature or the speed of the internal combustion engine.
