Abstract
Abstract An electric power generating system including a motor vehicle defining a passenger compartment and an engine compartment; an internal combustion engine retained in the engine; an exhaust system defining a passage for discharging exhaust gases produced by the internal combustion engine; and a primary heat exchange system coupled to the exhaust system means and defining a primary chamber adapted to transfer thermal energy from the exhaust gases to a working fluid; a cooling system for circulating cooling liquid in a path that results in removal of thermal energy from the internal combustion engine; and an auxiliary heat exchange system coupled to the cooling system and defining an auxiliary chamber adapted to transfer thermal energy from the cooling fluid to the working fluid. Also included are an expander having a rotor driven by expansion of the working fluid; working fluid tubulation for circulating the working fluid through the primary chamber, the auxiliary chamber and the expander; an electrical generator coupled to the rotor so as to be driven thereby; and electrical energy storage means connected to receive electrical energy from the electrical generator. The primary and auxiliary heat exchanger systems recover from the engine's exhaust and cooling systems unused energy which is converted into electrical energy by the expander to improve fuel efficiency.
