Auxiliary unit for motor vehicles, has secondary thermal engine in addition to primary drive engine that uses waste heat from primary engine to generate mechanical drive energy

摘要

The device has a secondary thermal engine (3,4,7) installed in addition to the primary drive engine that uses the waste heat from the primary engine to generate mechanical drive energy. A heat exchanger (4) integrated into the exhaust system (9) of the motor vehicle is provided to produce a confined working gas, preferably steam.
