摘要： The present invention relates to a method for diagnosing unintended fuelling from one or more fuel injectors of a multi cylinder internal combustion engine during engine operation. Pressurised fuel is intended to be distributed by means of said fuel injectors from said accumulator tank to the cylinders for combustion. An oxidation catalyst is arranged downstream said cylinders. The method comprises the steps of: determining (S1) the pressure in the fuel accumulator tank and whether said pressure is decreasing; and determining (S2) whether the actual amount of fuel provided by the pump unit exceeds the demanded amount of fuel. The method further comprises the steps of: determining (S3) whether the temperature associated with the oxidation catalyst is above a certain level and/or determining (S4) whether the air/fuel ratio is below a certain level and/or determining (S5) whether an amount of particulate matter is above a certain level; and confirming (S6) an unintended fuelling based on the determined conditions.
