<p>The present invention relates to a method for identifying a malfunctioning fuel injector (1-6) associated with an individual cylinder of a multicylinder combustion engine (50), comprising an accumulator tank (120). The method comprises the steps of: determining a first pressure value (P1ij) of the accumulator tank, prior to supplying fuel to one individual cylinder; supplying fuel to the one individual cylinder during a predetermined on-time; determining a second pressure value (P2ij) of the accumulator tank after the fuel supply; processing the first and second pressure values so as to establish a test value (Qi); and identifying, when applicable, a malfunctioning fuel injector based upon said established test value (Qi). The invention also relates to computer program for identifying a malfunctioning fuel injector, a computer program product comprising computer program code for implementing a method according to the invention, a computer, and a platform having a computer.</p> |
