Exhaust turbine driven generator for IC engine - recovers energy from exhaust gases to drive a generator which supplies vehicles electric equipment

摘要

The system uses exhaust gases to drive a turbine which, in turn, drives an electric generator to supply power for ignition, battery charging, fans, pumps, and the vehicle electric system. The turbine (1) is mounted in the exhaust pipe so that the momentum of the exhaust gases (A) is converted to rotation of the turbine. To assist the turbine, partic. at high vehicle speeds, a tapered coaxial duct (3) placed around the exhaust pipe allows the air stream (B) to pass over the turbine blades. An additional application for the generated energy is supercharging, using an electrically driven constant speed compressor on the air inlet. The saving provided by the system is of the order of 10% for engines having a capacity of less than two litres.
