Abstract
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).
