摘要： 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.

摘要： A rotary piston engine comprises a housing (10), which forms an interior space (11), and at least two rotary pistons (20, 30), which are arranged in the interior space (11). Formed on the interior space (11) are an inlet opening (13) and an outlet opening (15) to guide a fluid through the interior space (11). The rotary pistons (20, 30) are thereby driven by fluid flowing through. Each rotary piston (20, 30) has on its outer circumference at least two sealing strips (21, 31). According to the invention each rotary piston (20, 30) comprises at least two cavities (27, 37), in each of which a tube (38B) or an elastic solid rod is arranged. The sealing strips (21, 31) project into the cavities and against the tube (38B) received therein or the elastic solid rod. Through the tube (38B) or the rod, the sealing strips (21, 31) are pushed radially outwards.

摘要： An internal combustion engine has a plurality of engine units, each having a working space, in which two rotary pistons are arranged so as mesh with each other and thereby divide the working space into an inflow region and an outflow region. Each engine unit has a closable inlet opening to the inflow region and a closable exhaust gas outlet opening. The internal combustion engine further includes a feed-line pipe to the inlet openings and an exhaust gas collection pipe connected to the exhaust gas outlet openings, so that the engine units are connected in parallel with each other. The internal combustion engine further includes exhaust gas lines which connect the engine units with each other in series. In certain cases, a control device operates some of the engine units either as internal combustion engines, or as expansion engines.
