摘要
Method and device ( 1 ) for boosting an intake pipe ( 4 ) of a turbocharged engine ( 5 ) with compressed gas. The method includes storing gases in a vessel ( 12 ) at a pressure greater than atmospheric pressure and, afterwards in injecting the gases into the intake pipe ( 4 ) in order to temporarily increase an inlet pressure during low-speed operation phases. The inventive device includes a connection for temporarily and alternately connecting the storing vessel ( 12 ) to an exhaust manifold ( 6 ) for recovering the gases during engine brake phases or to the intake pipe ( 4 ) during the temporary low-speed operation phases. The connection comprises a heat exchanger ( 10 ) mounted between the exhaust manifold ( 6 ) and the vessel ( 12 ).
