Circuit arrangement for energy recovery from waste heat stream of internal combustion engine in vehicle, has waste heat recovery circuit, which is designed as steam circuit

摘要

The circuit arrangement (1) has a waste heat recovery circuit (AK), which is designed as a steam circuit, where multiple expansion devices (2) are arranged in the waste heat recovery circuit. Each expansion device is provided for driving a separate auxiliary unit of an internal combustion engine. The expansion unit is connected in the waste heat recovery circuit in series or parallel connection. An independent claim is also included for an operation method for a circuit arrangement for energy recovery from a waste heat stream of an internal combustion engine in a vehicle.
