Abstract:
A method and a device for purging an injector in a fuel injector system of use in regeneration of a particle filter. The aging of fuel is determined and compared with a fuel aging threshold value, and a purge request is activated if the threshold value is exceeded. On activating the purge request the satisfaction of the conditions of purge activation are verified and, if satisfied, the purge is activated. The purge is continued while the conditions are satisfied until the quantity of fuel purged reaches a quantity of fuel to be purged.
