Abstract:
The invention relates to an exhaust-gas energy recovery system, comprising an exhaust-gas line system ( 111 ) for conducting exhaust gases of an internal combustion engine and comprising a motor-generator device ( 101 ), which can be driven by means of exhaust-gas energy in order to produce electric current. The exhaust-gas line system ( 111 ) comprises a first line arm ( 124 ) to the motor-generator device ( 101 ) for conducting exhaust gases into the motor-generator device ( 101 ). The motor-generator device comprises a motor ( 100 ), which is arranged in such a way that the motor can be driven by a pressure of exhaust gas flowing through the motor. The invention further relates to a corresponding method for exhaust-gas energy recovery.

Claim (Index 1):
An exhaust gas energy recovery system comprising:\n an exhaust line system ( 111 ) for guiding exhaust gases from a combustion engine, a motor/generator unit configured to be driven by exhaust energy to generate electrical energy, wherein the exhaust line system comprises a first line arm to the motor/generator unit for guiding exhaust gases to the motor/generator unit, wherein the motor/generator unit comprises a motor which is arranged to be driven by a pressure of passing exhaust gases, and wherein the motor is a rotary engine comprising:\n a housing defining an inner room, \n at least two rotary pistons arranged in the inner room, \n an inlet opening which is connected with the exhaust line system for introducing the exhaust gases into the inner room, and \n an outlet opening for the exhaust gas defined at the inner room at a side opposite to the inlet opening, \n wherein each rotary piston comprises a gear rim at its outer circumference, and \n the rotary pistons are arranged such that their gear rims mesh.
