SYSTEM FOR PROTECTING A TURBO-SUPERCHARGING SYSTEM, IN PARTICULAR FOR PREVENTING A RESPECTIVE DAMAGE WHEN A PRESSURE OF A RESPECTIVE LUBRICATING OIL IS INSUFFICIENT

摘要

A system to protect a turbo-supercharging unit (T, C) and, more specifically, to prevent a respective damage when a pressure of a respective lubrication oil is insufficient comprises a first bypass means (OV, GB) of exhaust gas controlled as a function of a pressure of the lubricating oil of the turbo-supercharging unit (T, C) in order to allow to at least a part of the exhaust gas to bypass the turbine (T) when the pressure is below a first predetermined threshold.
