Title: SYSTEM HAVING A SECONDARY CURRENT GENERATING ASSEMBLY FOR THE SECONDARY CONVERSION INTO ELECTRICITY OF EXHAUST GAS HEAT FROM A PRIMARY CURRENT GENERATING ASSEMBLY
Abstract:
The invention relates to a system having a primary current generating assembly (10) comprising a primary thermal engine (7) and having a secondary current generating assembly (9), in particular an electric turbo compound installation, for the secondary conversion into electricity of exhaust gas heat from the primary current generating assembly (10), wherein the secondary current generating assembly (9) comprises an exhaust gas turbine (26) arranged in an exhaust gas stream (25) of the primary thermal engine (7), and the exhaust gas turbine (26) drives an electric secondary generator (24). In order to improve efficiency, and in particular to reduce fuel consumption, it is proposed that an exhaust gas cooler (29) followed by a compressor (30) are arranged in the exhaust gas stream downstream of the exhaust gas turbine (26), the compressor (30) being driven by an electric motor (21) and the rotational speeds of the compressor (30) and the exhaust gas turbine (26) are controlled by a process control system (33). The invention also relates to a vehicle equipped therewith.
