ESTIMATING A LEVEL OF CORROSION OF AN INJECTOR

Disclosed is a method for estimating a level of corrosion of an injector of an engine, the engine including a reference injector and at least one other injector, each injector including a tip in fluidic communication with a combustion chamber specific to each of the injectors, the respective combustion chamber of each injector also being in fluidic communication with an exhaust system of the engine. The method includes: while the engine is stopped, inhibiting a propagation of the gases from the exhaust system toward the tip of the reference injector; determining a static flow rate of an injector and a static flow rate of the reference injector; and estimating a level of corrosion of the injector by comparing the static flow rate of the injector with the static flow rate of the reference injector.
