INTERNAL COMBUSTION ENGINE, SUPERCURRENT BY A GROUP OF TURBOCHARGERS, SOME OF WHICH MAY BE OUT OF SERVICE.

摘要

Supercharged piston engine. BR/ Three turbochargers (14, 15, 16) are mounted side by side on a side wall (24) of a hermetic casing (23) fixed to the engine (11); the duct (12) for collecting the exhaust gases from the engine (11) is connected to the inlet of the turbine (17) of the central turbocharger (14), and a pivoting device (28) for routing the exhaust gases is disposed at the outlet (25) of the turbine (17). In a first position, it makes the outlet (25) communicate with the inlets of the turbines (19, 21) of the two adjacent turbochargers (15, 16) and, in a second position, it makes the outlet (25) of the turbocharger directly communicate central (14) with the exhaust pipe (29). BR/ Application to medium power piston engines.
