Abstract

Fresh air enters the inlet (7) of the compressor (6) which discharges through a pipe (4) into the engine inlet manifold (2). Exhaust gases from the exhaust manifold (3) enter the turbine (10) which is directly coupled to the compressor and leave after doing work through an exhaust pipe (18). The compressor discharge (4) has a branch (12) leading to the turbine inlet so that part of the compressed air can be re-expanded in the turbine, returning the work that has been done on it. By varying the amount of compressed air bled through the turbine one can control the torque requirements independently of the air quantity delivered to the engine.
