Combustion engine coolant circuit has heat exchanger sections/heat exchangers independently supplied by pumps; pump(s) can operate with flow delay, especially as generator

摘要

The coolant circuit has at least one control element (6), a coolant pump (4), a cooler (3) and a heat exchanger (18) for heating the vehicle interior, whereby at least two heat exchanger sections and/or heat exchangers are each supplied by a pump (14,16) mutually independently. At least one pump can operate with a flow delay function, esp. as a generator
