Engine waste heat recovery system

摘要

A waste heat recovery system is provide for a vehicle having a plurality of heat generating components and an engine cooling circuit. The system includes a heat collecting circuit collecting heat from the components and the engine cooling circuit, and a power generating circuit operating on a Kalina cycle. The heat collecting circuit operates with a first working fluid, and the power generating circuit operates with a second working fluid. The power generating circuit drives a turbine which drives an electric generator. A heat transfer unit transfers heat from the heat collecting circuit to the power generating circuit. The power generating circuit including an exhaust gas cooler for super-heating the second working fluid.
