OPERATING METHOD FOR AN INTERNAL COMBUSTION ENGINE IN COMPRESSION BRAKING MODE, INTERNAL COMBUSTION ENGINE CAPABLE OF OPERATING IN BRAKING MODE AND AUTOMOTIVE VEHICLE EQUIPPED WITH SUCH AN ENGINE

摘要

This method operates an internal combustion engine (1) of an automotive vehicle (T) in compression braking mode and includes the steps of recovering at least a part of the exhaust gases of the engine (1) via EGR means (2), mixing the recovered gases with fresh air (F1) and fuel in order to form a gas-to-fuel mixture and injecting this gas-to-fuel mixture within at least a cylinder (12) of the engine (1) when a piston of this cylinder moves from its bottom dead centre position (BDC) to its top dead centre position (TDC). The engine (1) comprises two turbo-chargers (3, 4) whose turbines (31, 41) are located in two different exhaust lines (61, 62) which extend in parallel, downstream of an exhaust gas manifold (13).
