<p>#CMT# #/CMT# The device (1) has a waste heat utilization circuit (3) in which an operating medium is circulated, where an evaporator (4) is arranged in the circuit for evaporating the medium. Expansion machines (12, 13) are arranged downstream of the evaporator for expansion of the medium at low pressure. A condenser (11) liquefies the medium, and a compression machine (8) compresses the medium at high pressure. A preheater (15) is arranged between the compression machine and the evaporator for preheating the medium and removing heat from a cooling circuit (16) that cools an internal combustion engine (2). #CMT# : #/CMT# The evaporator is formed as a heat transmitter. The compression machine is formed as a pump. #CMT#USE : #/CMT# Waste heat utilization device for use in an internal combustion engine i.e. piston engine, of a motor vehicle (all claimed). #CMT#ADVANTAGE : #/CMT# The device is designed so as to be adapted to different operating conditions of the internal combustion engine while achieving increased efficiency of the engine. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic connection diagram of a waste heat utilization device. 1 : Waste heat utilization device 2 : Internal combustion engine 3 : Waste heat utilization circuit 4 : Evaporator 8 : Compression machine 11 : Condenser 12, 13 : Expansion machines 15 : Preheater 16 : Cooling circuit.</p> |
