Abstract

A method (100) of identifying malfunctioning of a compression release arrangement (7) of an internal combustion engine (1) is disclosed, wherein the engine (1) comprises a plurality of cylinders (c1-c4), the compression release arrangement (7), and an inlet manifold (14) arranged to supply air or an air/fuel mixture to each of the plurality of cylinders (c1-c4). The method (100) comprises, when the compression release arrangement (7) is in an activated state, obtaining (110) data representative of pressure peaks (pp) in the inlet manifold (14) and the crank angle/angles (CA) of the crankshaft (16) of the engine (1) at which the pressure peaks (pp) occur, and identifying (120) a number of cylinders (c1) of the plurality of cylinders (c1-c4) associated with a malfunctioning of the compression release arrangement (7) based on the obtained data. The present disclosure further relates to a computer program, a computer-readable medium (200), a control arrangement (21), an internal combustion engine (1), and a vehicle (2).
