Beschreibung
Zusammenfassung:	The invention relates to a method for monitoring a degree of clogging of the starting injectors of a turbine engine, which includes: a combustion chamber into which at least one starting injector supplied with fuel leads, said starting injectors being suitable for initiating the combustion in said chamber by igniting the fuel; and a turbine rotated by the gases resulting from the combustion of the fuel in the chamber, the method being characterised in that it includes the steps involving: the measurement (1100), during a phase of starting the turbine engine, of the temperature of the exhaust gases at the outlet of the turbine; and the determination (1200), from the changes over time in the temperature thus measured, of a degree of clogging of the starting injectors. The invention also provides a system for monitoring a degree of clogging capable of implementing the method, and a turbine engine including such a system.
